Over 30 years ago Mack dominated the dump truck segment. Thats all they used to use in the coal mines.
That's awesome to hear! Macks are my favorite, I love hearing anything new I didn't know.about them.
Been longer than 30 years.more like 60 or more,I'm old just not that old. I remember B model MACK dumps all over the place.
It’s always a pleasure to watch an individual that is clearly enjoying what they do. Can’t help but smile at the older equipment you are running.
I really appreciate that! I really love and enjoy it. Thank you for watching!
Hey I see your a newer channel and you post constantly. I love the video, especially this one. It brings back so many fond memories of riding with my grandfather in his early 90s single axle Mack dump truck. Whatever you do I really hope you stick with this UA-cam thing because I really enjoy watching your videos
That means so much to me, I really appreciate that and just want you to know because of your comment I will be putting in 110%. Thank you for that! And I like your name, because I was that Mack kid and I still am. My entire house is filled with Mack stuff hahaha
Loved the engine sound track thru the video. Very inspiring and exciting... great job!!!
Thank you! I really appreciate that!
Just found your channel, Bro. You're really bringing back memories. Thanks for the ridealong👍🇺🇲🤠
Thank you for riding along! That means alot to me thank you!
You take me back to when I started driving trucks! I started with tractor trailers at 24 years-old. I'm 62 now. Started driving 6 wheelers and 10 wheelers at 18 years-old. Whatta pisser! Rack body for a garden center and oil trucks and a dump truck for a different garden center 😂. So much fun! Bad a?? driving a 24 ft dry van 6 wheeler up to and all over Connecticut from NJ. Man! Keep posting! God bless and safe travels!
Hahahaha that's awesome man and thank you! I'll be doing my best!
Keep posting bro, legit don’t stop that’s difference in these UA-camrs who make it big. Even if you don’t want to make it big I love your content bro, it’s inspiring.
I really appreciate that! I have no intentions of stopping! And making it big wouldn't necessarily be a bad thing but I'm happy to have the people interested that i do! Thank you for watching
I am glad you post a lot. As a mechanic, I thoroughly your videos, Thanks man!
Thank you! You will love the next one lol be sure to check it out! I did a tiny bit of mechanic work lol I can fix just about anything, maybe not the right way but I try to get it done lol
Awesome! Sometimes you do what you have too in order for things to work. Ive been a school bus mechanic for years and have worked on every make and model engine. I have also worked on trucks, mostly Cat on the truck side.
@@natewiltsie6279 I agree! That's so awesome man!
Enjoyed the Ride in the Mack !!!! Thanks .... I had the same thing happen with a load of busted up concrete in my single axle International . thank goodness for the guy there with the excavator lol
5 speed Maxitorque is a good gearbox by Mack just got to get use to shifting slower and let those RPMs drop to shift it’s just a different style of driving when compared to a multi speed gear box that requires a progressive shift method I don’t know what to say about useing the Jake or as Mack called theirs Dynatard Check your gearbox oil and make sure your clutch is properly adjusted ???I don’t know what else to say !!?? Good luck
Thank you I really appreciate that! Thanks for watching
The way you described putting the PTO in the gear is definitely the correct way
Thank you! First comment about that! I really appreciate that!!!
That's how I always engaged the PTO as well.
I drove an old International 6 wheeler for a short bit, it had the red button 2-speed rear.
keep them old trucks going love that sound
I'll do my best, thank you!
Hello from New Zealand just found your channel and must say awesome work I to myself grew up driving and being taught how to drive older trucks fro r-series Mack’s to superliners plus ford 9000 and k100e kenworths
Keep up the great content
Thank you that's so cool your watching from New Zealand! I really appreciate you watching and that's so awesome you taught yourself and learned in the older trucks! You and I are two of the same. I'll be doing my best to keep the content coming!
@@Only4Trucks i love the old r-series to drive plus the video you when you picked theat one up and drove it back home was a good watch
Those Mack’s are fun to drive, drove one hauling wood chips and one for gravel. The one for gravel cut out one day and wouldn’t go over 35-40 wide open after the first load and the shop replaced the fuel filter and air filter and something else and she opened back up. My uncle used to get on to me for having the jake on unless I was down shifting…lol, he was my trainer and after those two jobs I moved up to a Peterbilt and cow hauling, did some log hauling on my off days. Awesome times🙏🏻🇺🇸💯🤙🏻and I was no mean’s saying you were doing it wrong, just telling you how they taught me as a teenager. You’re a damn good driver!
Nah man no offense taking! I love the story, I enjoy hearing about how people were taught and what they drove in their life time! I appreciate you watching!
@@Only4Trucks Yes Sir I’m the same way and I learn new and better ways of doing things just by watching and listening. I’m 53 now and still learning. God Bless You and stay safe 🙏🏻🇺🇸💯🤙🏻
Really enjoying these videos behind the wheel! The one through NYC was awesome! I remember riding through NYC with my dad in the 18 wheeler.
Keep them coming! Dig the old iron.
These old masks with the super wide ratio 5 speeds have always been cool to me. 8,9,10,13,18speeds ... And then the obnoxiously wide ratio 5 speed. They're a beefy trans for sure. Are you winding it out enough between shifts? Never piloted one but I always herd you need to run them up to the governor before shifting
You definitely do run them up to their limit then shift lol I think I was running them out for the most part, I may have short shifted if I was empty but I'll never do that loaded unless I'm coming up to a red light lol.. and that's awesome! And I really appreciate that and I appreciate you watching! Hang on for the ride because we have plenty to go!
I’ll give you the info you are all looking for .The truck was originally a tandem tractor with the five speed . The rear is out of an older single axle tractor that was turned in to a dump truck . The motor blow on the old truck so I made this one you all see now .cut the tandems out ,swap body and rear from the old one . Now with the lug in 5th is because of the old air to air in front of the rad is probably leaking and needs a core .that would be my start !
Definitely needed this comment! I wonder if I can pressure test the air to air
Check how fuel pressure you have while idling. Then check if it raises while on throttle. Could be as simple as clogged fuel filter, spring return, clogged air filter. Lot of times guys over look the boots on turbo piping and while you think u may not have a boost leak, the smallest leak will cause that issue.
What's up driver, your little Mack is cool. I would invest in a swing tail gate, it makes life way more easier, trust me. I won't own a dump without one, you can haul and dump anything without having major issues. Maybe try some fuel injector cleaner and dump some oil in the fuel to help lubricate the pump. The way they condition the fuel now a days it doesn't burn hot enough for the older truck engines. I even do it in my pick up truck's, the old Ford's with the 7.3 diesels. Stay safe out there my friend and keep the videos coming and always travel safely catch you on the next one.
Thank you! I appreciate that! And we were just talking about a swing gate or barn door for this thing lol. Your right on time there! And thank you for that, we're gonna try that along with some other stuff. I'll be keeping the videos coming, thank you so much for watching!
New sub here. Your vids came across my feed cause i was checking out some truck stuff and if my guess is right your pretty close to me. I grew up around here. Anyway keep up the good work ,i enjoy your videos! Cheers!
That's awesome! Maybe I could meet you at a show one day and thank you I really appreciate that and I'm glad you found the channel!
Enjoyed the ride good job👍👍
Thank you and thank you for watching!
Check your Pollution control valve routing (Puffer Valve). It wont let the fuel rack fully open until the turbo has created a certain amount of boost. There were a couple ways to tune/"delete" the pcv entirely while leaving it in place. I believe you could use a penny to block off one of the airline restrictions. Youll get more bottom end power but also easy to overfuel cylinders.
Follow airline from turbo to intake side of block and youll see the little valve there I think mounted on the manifold.
I will check that for sure
I’m 11 months late but I commented this as well. Still scrolled the comments to see if anyone suggested it.
My new faveourite channel!
Thank you so much! That means a lot to me and I really appreciate that! Glad you found me and thanks for watching!!!
The DM 237 I drive wouldn’t spool up the turbo quick and it kills it on the mountains.
There is an air line that goes to the fuel pump I believe, it’s a puffer valve and it would restrict the fuel until the turbo spooled up and got the RPMs back to 1600. My uncle plugged it and it lets it have fuel before that turbo spools up, makes it smoke but boosted the HP in that critical moment.
Worth looking at
Maybe you’ll see this it’s been a year haha anyway keep on keeping on
Like mentioned, no smoke, not enough fuel. Install pressure gauge after lift pump and hang on air cleaner so you can monitor while driving. I had similar issue and lift pump was just bad enough it lost pressure under load. Puff limiter? It pulls fuel until you build boost. Many unhook it but will smoke bad(not good if you have e check). Small air cylinder on front of injection pump with line on it.
Jake switch, yes just adjust it until works properly. No biggie.
Thank you very much! Definitely gonna try that to check the pressure, and also maybe delete that limiter because we have no e check or concerns where we are
Love them old macks. Looks like you got a nice fleet there and youre fairly local to me. Hopefully i catch you on the road sometime
That would be awesome for sure! I know a mccann electric and a mccann that worked for Glasgow, any relation?
No relation to the electric, im not sure if any of my family works for Glasgow or not, id have to ask them
@@JMcCannATC 10-4 figured I'd ask lol
That Mack 5 spd Maxitorque was made for use in the city and local roads with not a lot of grades for simplicity in heavy haul where multi speed progressive shift driving is not needed or required
I appreciate the comment!
I have drove those Mack's all of my life and that is the first one I have seen with one stick most have the 5 speed maxe dine with the low and high and reverse on 1 Pole and the 5 on the other 10/4
That's awesome! I appreciate you watching
You said in a different video that the engine was replaced. The truck should have had a 2 valve E6 285 with a engine mounted charge air cooler. It looks like the truck now has a e6 4v engine with CAC mounted in the front. The 5 speed trucks usually were matched with a low rpm power band that produced torque from around 800 rpm to 2100 rpm hence using the 5 speed.
The econodyne was designed to be a low rpm engine power band typically designed 1200 to 1800 rpms.
I think the engine set up is not match to the drive train
I also saw the econodyne emblem on the hood and said uh oh to myself if it truly is an econodyne under the hood mated to a straight 5 speed. Easiest way to tell is if it pulls to 2100rpm it’s not an econodyne. Being air to air does not mean it for is an econodyne, but it could be. If it only pulls to 1800rpm then it is. But even if it is, it should be able to pull 5th gear in an empty single axle truck.
I’d be looking into the boost line to the air/fuel ratio valve on the pump and puff limiter. Sounds like the afc isn’t getting a good boost signal to let the rack go to full fuel, or the diaphragm is leaking and therefore the rack isn’t going to full fuel.
I think you are exactly right! I said the same, the thing that gets me is my friends and family who drove this truck over s decade ago swear it used to be plenty fast and never had this lagging lug issue. But I question if they just thought it was fast back then when it wasn't because of the time change now a days things are much different. But I don't know. We will look over a few things and attempt to make upgrades but no matter what we still plan to change the transmission anyway. We have an 8ll here we might stick in it but we haven't decided for sure
Check to see if the waste gate is opening and closing. You can hear it spool but it won’t open and close at the right time causing it to never have enough boost.
Will do
Used to drive by your yard back at a previous job. Always enjoyed looking at the older trucks in the yard. Didn’t y’all have an LTL9000 dump?
Wow that's awesome! We did but unfortunately it was rolled over running millings in Plymouth meeting pa so she was a goner
It’s the valve that controls pressure to the puff eliminator.. not letting the rack travel far enough..
Thank you for the knowledge, I'll be checking
Fuccck I just missed an opportunity to buy a 1985 Mack dump truck at auction. It sold for 10k 325k miles on the odometer. It Needed work on the tailgate, and it was a twin stick which I have no experience in. Also recently was in an accident, shattered my left elbow, broke some fingers, etc. those two reasons are why I didn’t buy it. Watching your videos makes me regret not buying it hahaha
The old Mack would make a nice little single axle, then if you can find a nice little single axle flatbed trailer it would be pretty cool.
Don't know a lot about trucks but I have watched a video once where some new trucks even had a auxiliary tranny that was air shifted maybe if you can find a 2 spd one or change out the rear-end with a 2 spd rear for more gear ratios to keep your rpms up so the turbo will properly spool up
I agree randy, we talked about it before, it could happen, I would love it
@@mike1397 that would help for sure, I just wanna make sure there's nothing elsewhere that isn't up to par before doing so
It’s already a single axle set up to pull a flatbed trailer on a pintle hitch lol. Why give up the versatility of a dump truck to make it a single axle tractor? 9 times out of ten it’s done the other way around.
D00d living the dream..
I'm trying! Lol
drove an old Mack triplex one time, never again :)
Ran a few 237s 5sp did the same lugged till it built power
Uh oh lol thank you for watching!
@@Only4Trucks anytime thanks for the videos
Hi from England 🏴 check to see if it has a diaphragm on Fule pump for boost smoke control it may be split or leaking
Wow all the way from England! That's awesome! Thank you and I will check for sure
i named my dog after the r-600 mack in mad max 2. great rigs.
That's awesome! I agree!
Can adjust the fuel plate on the injection pump give it some more fuel and a little more power
Definitely going to be doing that
When you’re on the hammer trying to accelerate in 5th, is it rolling coal or not? If it’s rolling coal, you’re getting the fuel just not enough air, clogged air filter, or a boost leak. If no black smoke, then it’s not getting the fuel, clogged filter, throttle linkage not going to full fuel on the injection pump, or something along those lines. Let me know.
It is not smoking when I'm holding it to the floor in 5th. The throttle linkage is definitely properly opening the fuel rack all the way. But I'm loving your insight so far hopefully we can come up with something!
It sounds like you have a air problem, can you hear a little whistle noise when acceleration is done definitely a air problem. It sounds like on the trans a syncronizer problem shifting.
@@Only4Trucks could be the pre boost fueling on the injection pump
I had a 85 r model with a 300 R and I'm not sure if yours has this part installed but mine has what's called a puff limiter valve, It is vacuum over air, controlled off of the intake manifold and when it gets gummed up it will not allow the rack to fully travel, just a epa/emissions thing,I disengaged mine by simply taking the air fitting off on the firewall that goes to the block on the intake, Hope that helps
l not allow it to fully travel when fuel is applied until there is enough manifold pressure to bypass I should say
@@brandonmcpherson2933 I really appreciate that, I am familiar with that part and plugging and or deleting them just to see more black smoke, but I haven't checked at all. I'm definitely going to
check the waste gate and associated parts
The anaroid valves come on different on different trucks, ask your parts guy to set you up with one that kicks in quick!!!
Good to know! Thank you for the knowledge!
No smoke no fuel
I hear that, thank you
Does it have a CB radio in it
Sounds like to me the overhead needs to be tuned up on that mack it not got the snap it should have. And you hear the engine hunting for idle when you let off the fuel it should not be doing that. Scratch that I see the problem it's dropping to many RPM's shifting the gears that's one of the reasons it's not spooling the turbo.
Is that Brittons yard?
Could do with a wash maybe a polish
Cool truck tho
Most definitely! It should get painted this summer!
When was the last time the turbo was taken off to clean or rebuilt it sounds like it is sticking open or close for a second
Probably never honestly
No waste gate on those engines
Very good to know!
My 78 does the same thing with the Jakes
Lol old stuff rocks
Cool video is the Ford tractor yours.
Thank you! My bosses, I don't own them, but yea the fords are ours as well!
👍👍👍👍💯💯💯💯💚💚
Is your puff limiter connected or plugged?
I will have to check
What engine? Cummins has what’s called an aneroid valve cat calls it a AFR either way there’ll be a boost reference line going to a valve on the pump that give the engine more fuel as boost comes up
I believe a Mack 350
I don't hear the turbo spooling. Sounds like it's suffocating a little, like an air issue. Filters or turbo. Or the gear ratio is not matched!!
I agree! Gear ratio is definitely not matched lol
Your hoses or tubes may be collapsing when you accelerate.
@@jaydouglas-up7fv it feels to consistent and also the way of when it lacks the power doesn't make.me.believe it's that. Because there's different points through the lower gears it has all the power
Hot dog!😂
😂😂😂
It sounds like it is lagging when in low gear don't know if it's missing
It does lug quite a bit but it doesn't sound or run like the engine has a miss to me. I'll try to get better audio for you in the future to help judge what's going on with it
Air filter in upside down ?
I don't believe so but I have to check now lol
check out boston trucker
I have! Love his videos!
Sounds like you may not be revving it to 2,100 in 4th, then it's below 1,000 in 5th...
What part of pa. Are you from ?
Philadelphia, I currently live in chalfont Pennsylvania
@@Only4Trucks
I live in King of Prussia worked in Chalfonte for a summer
The turbo could be getting weak
Thank you for that I will be checking
Why do you leave the jake on all of the time?
To get the rpm's down faster to be able to shift sooner. It keeps she wheel speed up. If you were running up a hill or with a heavy load you wouldn't make the shift any other way
@@Only4Trucks Yeah...you could make the shift without it....all trucks don't have a jake and they are shifted.
@@jimmywarren6685 it's just the 5 speed and the lag this truck has makes it a bit worse. But I agree with you
@@Only4Trucks We had one many years ago...no jake...and I know what you are talking about.
take the jake off when you dont need it you put less pressure on a old engine way better for it
To an extent I agree, it helps upshifting alot. But also having fun for the videos sake.
Shift slower and let the rpm’s come up. The olds r models need a bit of patience
Yes sir!
Does the truck have a waste gate maybe it’s sticking open and resulting in turbo lag
I will have to check I don't know
R 85 was a 237 r 86 was a 300
Makes a lot of sense!
First you need to learn to drive with your rpm gauge and not your speedometer that truck is fine it's a 5 speed it has long winded gear changes and stop revving the motor up so much did you learn to drive in south America that's how they drive constantly revving the engine
I would consider waste gate on the turbo is sticking
I'll be checking, thank you!
