Loved helpin you pull her. Apart boss Man and will love even more!! Helpin you put ole Kenny. Back toghether again!! 👍👍👍 long live the 1396!! And ole Kenny!! ❤❤❤❤
As a very young child, I would sit for hours and watch an old diesel mechanic (RIP Bob Wallace) that was amazing with the old Detroit’s, he told me every damn thing he knew about them, not sure why because he complained about literally everything, but he liked me I guess..listening to you reminded me much of how he was with his knowledge of those old Detroit’s. Great video
And that class , is today's lesson on 1693's . Tonight's assignment is to read the manual ,there will be a quiz tomorrow , test next episode 😳 Thanks Jeff , always keeping my interest peaked ! 😜👍❤️
I still kick myself in the ass !!! I had a chance to buy a 74 A model Kenworth with a 1693 . From my friend that I would rent when my old cabover Freightliner PC Cat , would go in for repairs . Had the shop foreman at that time tell me. You know why Cat quit making the 1693 ? They couldn’t make enough money on parts because they ran so good!!!! Thanks Professor JPAYDIRT for another CAT educational video !!!! 👍👍👍👍👍 ❤️❤️❤️❤️❤️
First time I have ever heard such a beautiful simple description of a 1693 PC and DI comparison. Personally, I'll take a PC over a DI, just for the nostalgic sound and great conversation piece. Keep up the great work you do.
Interesting video, I'm looking forward to watching the buildup. Here's a thought, sell the old pistons (or piston half's) to raise some money for Shane, I'm sure there's guys like me looking for cool stuff for there workbench.
YES YES YES YES YES!!! Old Kenny back on the table... well the heart anyway. Yeah, that would be awesome to see the process to convert to DI, but I totally get that it may not really be worth it. And leaving it as a PC should test/prove the switchblade turbos a little more too! Thanks for another AWESOME video!
Great video. Interesting info on the cat engines. I’ve worked on school bus and motorcoaches for 40+ years. In our world we didn’t see many cat engines. We purchased a Van Hool with a C13, we couldn’t keep head gaskets in it. We repowered it to a Detroit series 60.
Nice to see you making a start on Old Kenny, uncle. But I think you should take a break sooner or later otherwise you might need a overhaul. Emerald is just how I left it and mum is enjoying her stay... nice and quiet. Talk to you and Tammy soon. Cya.
I drove a 73 kw long hood with a 1693 cat. it had 260 in wheelbase. 800 thousand plus miles and supposedly had only one injector replaced. 3-4 mpg. Never had any other truck out preform,on any mountain pass, or top speed. The fastest truck I ever drove in the 23 years driving. Leon Peterson owned it, from Spanish Fork, Utah. fun truck.
I still have my set of multiple pre cup shims around here somewhere to index the glow plugs on the 330's that I worked on many moons ago. Actually had a 140g that had was turbo, non spacer 3306 and a 12g that was turbo spacer plate and it was unreal the difference between their power. I sure like the way you go in depth on your vids!
When I went thru Diesel training at Wilson Community College, my class installed a 1693 CAT in a 1986 359 Pete, in place of a Big Cam Cummins engine..... was a complicated process.
I wouldn't worry about the crank if you were to DI that 343. The 3406PC and the 3406B used the same narrow bearing cranks and B's will go to 600hp at the tires without any trouble if properly tuned. The reason on the 3406C and later engines for the wider rod was for bearing life. On a 3406 or B to be safe you want to roll bearings about 250k miles if it's a road truck, or about 175k or so if it's a heavy haul/low mileage application. Water aftercoolers are also very efficient compared to air to air's and maintain a more consistent charge temp, but if you use engine coolant then at cruise you loose some efficiency due to the coolant temp. However, if you isolate the aftercooler and run it on it's own system they are very good. I've done quite a few 855's and N14's that way and a few early 3406B's. Not 100% sure, but I think the 7FB 3406's were the highest factory pump timing and were around 26*'s (I'd have to look in the book to verify but that's close anyway).
Patrick you are not kidding!! Heavy equipment mechanic here and i used to love my job and couldn't wait to fix whatever problem was going on. lately I have been seriously considering quitting this career. Its no longer fun with all the shit engineering and horrible parts quality. Recently I had a new hydraulic pump straight out of the box grenade within one minute of operation, and very expensive boom cylinder leak worse than the bent one it replaced, and the latest was a "certified" reman perkins engine for a rock processor go nuclear with under 5 hours of run time due to a new pos temp sensor. Pissed isnt even close, the added down time for customers is horrible. One good customer is a lot like ol paydirt and loves his vintage equipment. I really dont give a rats ass about fuel economy. The machinery that will run all dam day and half dead will still out work this garbage they sell today. Cat, Commie Cat, McCloskey, and i wont even go into the dam semi bullshit.
Thanks for your response Jeff .i worked as a performance engine builder in the mid sixties to the late eighties Many Chevy and ford engines two very involved 440 molars that were quite successfull But returning to your 1693...recently last few yrs BMW was tasked with providing a 3 liter Diesel engine to mimic the performance level of the gas engine...they made considerable improvements to the piston design with Mahler They have a steel piston that is quite amazing....and very lite....you would certainly get them to make a set I’m sure
Nobody will make custom stuff anymore, I talked to clevite and Federal Mogul and they all said the same thing, ISO 9000 complient companys cannot deviate from the design of said part
MANS MOTOR? Oh yeah, PC vs DI Keep the PC It's all about Fuel air ratio and changing the air intake and turbo is Key to that engine being GREAT AGAIN! Keep p on Turning those wrenches. I loved those PC engines Life is not the same in the DI world for sure.
Ah the piles of uppers and lowers I have put in Cat blocks over the years! Old Kenny probably couldn't haul them all. lol Your cheapest route would be custom pistons. You could probably get a proper speced set of pistons for less then 2k. It wouldn't have the steel inserts for the top rings though. maybe there is enough room in the pan to stroke the crank and make up that pin height difference? Turn your 1693 into a C18!! :-)
with an IDI like this, you could run it off bacon grease or french fry oil and it wouldn't complain. Much more versatile than a DI (as long as you boil the water out of the oil first)
The 3406b had a narrow journal crank, check the bottom end every 250,000 miles. The 3406b/c manual had a wide journal crank, 750,000 miles plus before a bottom end.
Running those power levels is one thing. Pulling your loads is another ball game. I'd say your driving style allowed it to live as long as it did. I like seeing equipment pushed then reviewing the failure modes. Going DI would be interesting, but not something I would do on a machine I need to pay the bills with. I think if you get your air and fuel dialed in you will be more than satisfied with the end result.
@@donnatalielucasheimbigner7598 WTH is a "pre-cupper" ? U meant indirect injection ? This engine is direct injection. The ones I know about using the pre-chamber design usually run 20-22:1 [great for torque], but most happen to be N/A so no real gain against direct injected turbocharged ones of the same displacement [usually running at 16:1].
@@GIGABACHI Yes, I mean pre combustion cup- as this engine is. Fuel injected into a small "cup", with a glow plug to ignite it, before the flame front is applied to the piston through a hole above it. Allis Chalmers used this type for a long time, & with a turbo.
@@donnatalielucasheimbigner7598 adjust your glasses, my fellow diesel enthusiast. This thing is DIRECT injected into the bowl formed in the crown of the piston. There's is no pre-chamber on this model.
Hey Mr. Anderson. Will you be decking the block and head? Also line boring the crank? I've heard balancing dose wonders. I wound not change it over to direct injection! Stay PC please.
3406 A and B went to a wider rod and main bearing. Later figured out that the wider bearing on the rod still wasn’t wide enough especially when the DI 425 B model came about in late 85. Not to get into great detail of timing changes etc. putting combustion directly on top of the piston is hard on on bottom end. 3406C came out and had even wider rod journals. Same crank as a 3406E minus the gear up front
Hey Jeff As usual a thought full job..the bearing wear could benefit from getting the block main bearing bores ALIGNED HONED…FIND A SHOP THAT USES THE SUNNEN MACHINE…I CANT SAY ENOUGH ABOUT THE PRECISION OBTAINABLE AS YOU CAN SEVE FROM THE WEAR PATTERN….THE BORES ARE NOT BORED BY CAT YRS AGO ON ANTIQUE EQUIPMENT….GOOD LUCK
Always be careful handling the deck plate gasket. The 0.008" metal gasket can cut your fingers to the bone. The DI 3406 has "TP" rods-as wide as possible on the low side for high piston pin loads.
Make it a TT ! Screw the CAT Purists ! Make it a full blown hot rod ! and slap a PayDirt Engineering sticker on it ! 🤘🏻👌🏻👍🏻🤣 Thanks for sharing all the little details and intricacies about that old CAT engine. I feel like Indiana Jones discovering some neat shit ! 😁👌🏻
If you pulled the valve covers off a precup eng (1693) you could easily see if the head was cracked by checking the pc,s , if they were loose the was cracked
I always wanted a Kenworth W900 13 speed with a open pipe Loud caterpillar 6NZ a game called American truck simulator has been there for me someday the road will hear the rumble of my 6NZ
Hi Jeff ..I read your reply on your unsuccessful inquiry about federal mogul not wanting to make your pistons Mahle does in fact ,make a steel piston for a few applications...but Diamond pistons does make custom diesel pistons...if you can give me your email I would be glad to forward you the information about the engineering BMW did to make 650 diesel horsepower from a 3 liter inline six cylinder....they had mahle involved in the steel diesel pistons..which was not easy as many issues had to be resolved....but just a thought as I’m very impressed how much you have invested in this engine design...my limited experience with them has only been through listening to owners who had success with them in how they claimed they never wore out...but they were not in the higher horsepower ranges..good luck
So Jeff, would the cost of putting a winch on your truck. To pull trailer on, instead of ramming on. Be too much, to save the cost of damage to parts when ramming? Know little more work to set winch cable to pull on, but the overall shock loading when ramming is very hard on truck.
Depends what your going to use Old Kenny for when your done Jeff.Show truck work truck or both that would determine the horsepower.If your plans are just doing some hauling with the bottom dump or pulling nothing really heavy on the lowboy I think 425 to 500 would be good.I wouldn't go nuts with the horsepower if it's not necessary.
,,, much less money. Keep the rods, machine the 1693 pistons for a combo larger diameter heat plug that would have the combustion bowl shape to it. Actually wouldn't be a heat plug but a steel combustion bowl . And yes, you can ignore any balance problems on a six cylinder, just keep all the pistons the same weight, regardless of how heavy they are . If you want: quieter, cleaner, more power, easier on the walls and bearings, build a common rail system. I put this in Malinson's and or Rutherford's ear(s), also . Entirely within Malinson's capabilities .
Hi Jeff ..I’ve been watching you and am very impressed at your depth of knowledge...and your work ethic...what I don’t quite understand as money is not the only directive is why you want to bring a outdated back to life again I’m not saying that you need to switch teams..like the six Cummins..which when I first saw it introduced at a truck show and commented to the Cummins rep that it looked like a Plagiarized version of the 1693 cat...he kinda got pissed off But my point is why keep beating a dead horse...is there a possible interchange with a non emission C15 I see impressive power numbers for real world longevity use
Well the A model KW is a pretty popular truck for restoration and keeeping CATs first big bore on hiway truck engine in it is a must, I would equate it to restoring my 73 dodge challenger with a chevy motor in it, LOL and I have this same engine in my 637 CAT scrapers, it's called a D343 in the equipment but it's the same engine as the 1693
HI Jay Blaylock (lol), Question - will an AFR (Air Fuel Ratio) sensor work to tell you if you are getting the correct air? I work with some gas fuel injection engines and run AFR instrumentation and I can program fuel mixtures to a gnat's whisker, full throttle 12.1~12.8 in about any engine speed range. Wondering if the oxygen sensor put in the exhaust stream somewhere, before or after the turbo will help you know the Air/Fuel ratio being combusted [prevent piston failure] Ask yer engineer buddy with the calculator.
On Diesels they are monitored by Pyrometer or EGT, same as very high end race engines. Ideally one Pyro bulb on each exhaust port. But now I'm curious. Does anyone now if an O2 sensor could live in a diesel's exhaust stream ? I'm gonna say NO. Soot deposits and all that good stuff diesels are known for. Someone with the know how please chime in and set the record straight ! 👌🏻
You gonna use a 325 horse power intake manifold or are you going to go for a custom built one when you switch over to radiator mounted charge air cooler?
Yes 1693 is a man's engine with the need of a giant bank account to keep them up-the whole reason they came out with the 3406-which it has the same bore x stroke.
It's all about air (o2) fuel ratio. Black smoke is nothing but a waste of fuel. "0" gain in power. Get that ratio right throughout the full RPM range and you will be the winner instead of the dirtiest.
Hey, Jay, could you number the 1693 rebuild videos for us, please? That way we'd know if we were seeing them in the right order. Mostly for future review, like a second time they're watched. Thanks. Maybe for all the Old Kenny restoration.......
John Warden Spacer plate won’t increase the stroke. Only way to increase the stroke is to increase the rod journal throw on the crank, which increases the travel of the piston.
@@jcarne1015 i think he meant as a way to add space for a longer stroke to a shorter stroke motor. ie: bigger stroke crank, longer rods, taller pistons. so they don't poke out the top of the deck.
froto baggins Hopefully that’s what he meant. I’ve run across a few guys who thought that putting stroker plates under their Harley cylinders would increase the stroke though.
What good would be gained by changing it to the other type? The engine failed as designed. Would changing to modified parts improve the longevity of the engine? The expense of rebuilding a stock Cat engine is already too excessive. Reinventing the wheel with all the modification parts probably cannot justify the associated risk of premature engine failure.
what failed about design bet never saw a 1693 in person much less ran one thw only fail they had was cats piss poor counter bore liner ser up outside of that the runningest pulling engine there is hands down one thing your r ite about cost but then theyre all ridiculous anymore

I love them 1693 CATs They make gobs of low end torque and rattle like hell!
It's a ton of fun rebuilding the water pump! Never was a Reman for those engines. Back in the day, many R&R and rebuild of those pumps.
So glad to see you finally messing with this engine again and hopefully old Kenny soon keep the videos coming
School day today! I like seeing how stuff broke and how it was designed to work. Good explanations, thanks.
Jeff,Thank You for the very detailed explanations and demonstrations. You do very good work.
The motor rebuild is going to be fun for us. We aren't having to pay for the parts.
Yes your are................you know the drill, remember the white box with the subliminal messages on it LOL

Good idea Sir
It's always the kids in the front row of class! Lol.. great idea jim
the smoke rolling out the stacks bring fond memories mine was a 1693 ta most powerful truck I ever drove the old Pete was built for loads

Yup , check liner heights around base .
Interesting! Best regards from Germany.
I have many scars from those spacer plate gaskets. 343 was a good old engina.
Hell yeah twin switch blades
This is going to be an interesting project to watch, learning why I liked that qle W900 A with them Kitty Cat Ponies !! To Drive !!
Do I detect a the possibility of a road trip in your future or at least some of Kenny’s engine parts making a road trip to Ohio vist Brian and Bailey?
Brian is in Kentucky.
Look at the 10 minute mark & you will see the pre cup in his hand. Even the first 3406's were pre cup design. Glasses & eyesight just fine.
3406As could be either be PCs or capsule DI-- look it up.
I always wanted a Kenworth W900 13 speed with a open pipe Loud caterpillar 6NZ a game called American truck simulator has been there for me someday the road will hear the rumble of my 6NZ
Good gravy was you putting some fuel through that Joker. Do you plan on leaving it set the same as before it shucked that button?
Well, I think with the switchblade on it and some tempature probes, ya I don't know yet
Nice job explaining👍👍👍👍👍👍👍👍
Yes, it would be... interesting........
Hi Jeff ..I read your reply on your unsuccessful inquiry about federal mogul not wanting to make your pistons
Mahle does in fact ,make a steel piston for a few applications...but Diamond pistons does make custom diesel pistons...if you can give me your email I would be glad to forward you the information about the engineering BMW did to make 650 diesel horsepower from a 3 liter inline six cylinder....they had mahle involved in the steel diesel pistons..which was not easy as many issues had to be resolved....but just a thought as I’m very impressed how much you have invested in this engine design...my limited experience with them has only been through listening to owners who had success with them in how they claimed they never wore out...but they were not in the higher horsepower ranges..good luck

Pulled good until it didn't! 😀😬580+ ain't no joke! This will be an interesting series to watch
Nice video I did the one I had in my old 988 it was very interesting
Another engine Rebuild for Jpaydirt 😋😊
So Jeff, would the cost of putting a winch on your truck. To pull trailer on, instead of ramming on. Be too much, to save the cost of damage to parts when ramming? Know little more work to set winch cable to pull on, but the overall shock loading when ramming is very hard on truck.
Depends what your going to use Old Kenny for when your done Jeff.Show truck work truck or both that would determine the horsepower.If your plans are just doing some hauling with the bottom dump or pulling nothing really heavy on the lowboy I think 425 to 500 would be good.I wouldn't go nuts with the horsepower if it's not necessary.
,,, much less money. Keep the rods, machine the 1693 pistons for a combo larger diameter heat plug that would have the combustion bowl shape to it. Actually wouldn't be a heat plug but a steel combustion bowl . And yes, you can ignore any balance problems on a six cylinder, just keep all the pistons the same weight, regardless of how heavy they are . If you want: quieter, cleaner, more power, easier on the walls and bearings, build a common rail system. I put this in Malinson's and or Rutherford's ear(s), also . Entirely within Malinson's capabilities .
Hi Jeff ..I’ve been watching you and am very impressed at your depth of knowledge...and your work ethic...what I don’t quite understand as money is not the only directive is why you want to bring a outdated back to life again
I’m not saying that you need to switch teams..like the six Cummins..which when I first saw it introduced at a truck show and commented to the Cummins rep that it looked like a Plagiarized version of the 1693 cat...he kinda got pissed off
But my point is why keep beating a dead horse...is there a possible interchange with a non emission C15
I see impressive power numbers for real world longevity use
Well the A model KW is a pretty popular truck for restoration and keeeping CATs first big bore on hiway truck engine in it is a must, I would equate it to restoring my 73 dodge challenger with a chevy motor in it, LOL and I have this same engine in my 637 CAT scrapers, it's called a D343 in the equipment but it's the same engine as the 1693
So, less spacer, higher compression, just like shaving a head, I’ll buy that.
CATSkinner sez: "push'n dirt is soooooo much more fun"!!!😂🤣😂
Friday
What piece of equipment is that from??
HI Jay Blaylock (lol), Question - will an AFR (Air Fuel Ratio) sensor work to tell you if you are getting the correct air? I work with some gas fuel injection engines and run AFR instrumentation and I can program fuel mixtures to a gnat's whisker, full throttle 12.1~12.8 in about any engine speed range. Wondering if the oxygen sensor put in the exhaust stream somewhere, before or after the turbo will help you know the Air/Fuel ratio being combusted [prevent piston failure] Ask yer engineer buddy with the calculator.
On Diesels they are monitored by Pyrometer or EGT, same as very high end race engines. Ideally one Pyro bulb on each exhaust port.
But now I'm curious. Does anyone now if an O2 sensor could live in a diesel's exhaust stream ? I'm gonna say NO. Soot deposits and all that good stuff diesels are known for. Someone with the know how please chime in and set the record straight ! 👌🏻
so I think they do make one for a diesel
Great job on the video. Not sure why you are rebuilding another engine when the Mopar still sits there but maybe someday? Haha.
You gonna use a 325 horse power intake manifold or are you going to go for a custom built one when you switch over to radiator mounted charge air cooler?
A REAL 425 CAT!! GETCHA SOME OF THAT!!!
Yes 1693 is a man's engine with the need of a giant bank account to keep them up-the whole reason they came out with the 3406-which it has the same bore x stroke.
It's all about air (o2) fuel ratio. Black smoke is nothing but a waste of fuel. "0" gain in power. Get that ratio right throughout the full RPM range and you will be the winner instead of the dirtiest.
That's been my goal by going with the switch blade turbos I have doubled my oil life
That engine must have a whole lot of hours on it those 1693s were bullet proof.
Great video I learned something
Hey, Jay, could you number the 1693 rebuild videos for us, please? That way we'd know if we were seeing them in the right order. Mostly for future review, like a second time they're watched. Thanks. Maybe for all the Old Kenny restoration.......
👆🏻👍🏻😎
Thanks for the video.
Jeff, was that spacer plate used as cheep way to increase the stroke of the engine
It was for a flat deck surface, without counterbores
John Warden Spacer plate won’t increase the stroke. Only way to increase the stroke is to increase the rod journal throw on the crank, which increases the travel of the piston.
@@jcarne1015 i think he meant as a way to add space for a longer stroke to a shorter stroke motor. ie: bigger stroke crank, longer rods, taller pistons. so they don't poke out the top of the deck.
froto baggins Hopefully that’s what he meant. I’ve run across a few guys who thought that putting stroker plates under their Harley cylinders would increase the stroke though.
@@jcarne1015 oh, that wouldn't be good, much lower compression sure don't help power. lol
T-18 was a fine turbo on a 525 KTA
Hmmm. I bet it was wheezing trying to keep up LOL
The 1693 was not built in direct injection.
very good video....learned new thing or two. Thank you.
What good would be gained by changing it to the other type? The engine failed as designed. Would changing to modified parts improve the longevity of the engine? The expense of rebuilding a stock Cat engine is already too excessive. Reinventing the wheel with all the modification parts probably cannot justify the associated risk of premature engine failure.
what failed about design bet never saw a 1693 in person much less ran one thw only fail they had was cats piss poor counter bore liner ser up outside of that the runningest pulling engine there is hands down one thing your r ite about cost but then theyre all ridiculous anymore
