Nice job with your filming, editing and the pace of the video. It's sad that so many engine machine shops are closing across the country due to the high labor costs which translates into expensive valve jobs, crank grinding, etc on used parts. Then couple in that you can buy new replacement heads, or cranks from China for the same cost as rebuilding or re-machining the original OEM parts. I'd pay more to have my original parts rebuilt/machined any day over buying the junk parts from China. I'm glad that your shop is doing well in this new world.
Those "parts" from China are NOT up to OEM specs. I know of camshafts that the lobes rounded off in literally 3 or 4 months, & camshafts have snapped in half in less than 8k miles. I always get the parts i need from reputable American parts stores. It costs a little more, but at least you know they will last, & the parts stores will back up their warranty.
@@timothygeiger8271 Totally agree Tim. Restored/rebuilt OEM parts are night and day better than the new inferior parts from China. Most aftermarket companies having their parts made in China only care about price point. So, the Chinese make them as inexpensive as they can. People who buy replacement parts based on price pay for it many times over.
Yes, repairing the head instead of buying a junk head (either salvaged or China made or Mexican made) and just going with it (hey, it's JUST a tractor!) shows craftsmanship and PRIDE in doing the job RIGHT! He's a REAL MACHINIST, not a parts replacer or machine operator. He KNOWS what he's doing and WHY he's doing it. The tractor owner could get his tractor running for less, but I promise, it won't run longer (or better) than from Jim's.
@@unclejoe6811 i said in my comment the parts from China are junk! I don't use junk Chinese parts & don't plan to use them. If you read my comments, you would've seen where i said that.
Thanks to you I truly understand terms and processes that I have heard about for years. Doubt that I will ever have any true need of this understanding but but appreciate your sharing in a manner that is both informative and entertaining. Happy Easter to you and your family.
Those Ford tractors purrrrrrr like a kitten. Unique torque curves, too. As the engine lugs down, torque climbs. You'll run out of traction before you run out of torque. Yet that engine only puts out a whopping around 50-55 HP!
Love watching someone ELSE do quality machine work. Good stuff. I know the engine will start, idle, and run much more smoothly with good sealing valves.
Great video. I went to AAI in 1980-81 I learned to grind valve seats with the old stones. Then doing them working at a dealership 80’s. Yea they took time to do. We reamed the guides back then. The grinding the valves and hand lapping them in to the seats. If you were off you’d have to either grind the top or bottom of the seat. This 3 angle cutters are nice.
Yep, multi angle cutters change the game! We very rarely use the stones these days but we do still have them. Every once in a while they have their place!
Your workmanship is very, very good! I think you really take pride in doing your work and giving the customer the excellent finished product the customer wants and is paying for. GREAT JOB.
I enjoyed you guys using the modern way to cut seats. My valve seat geometry is quite rusty but I did work in the industry back in the 80's, My Automotive A/S degree is from 1978. Keep up the good work. Wish you could offer some training video's for today's students.
I really appreciate your job adn respect all what you offer the youtubers to learn; really nice clean job where many shops do not give a small care about those old engines even new ones; one of your biggest fans from Algeria thousands of miles away of you I say to you thank you so much.
Valve jobs have come a long way since I started working on cars. For some reason?...it was common to do a valve job at about 75k miles. Maybe the leaded gas? They used to knurl the guides and grind the seats and valves with stones. You were looking at maybe 150 bucks with gaskets and krylon paint. The cars ran way better but the knurled guides was a short term fix.
Yes the switch to unleaded also came with hardened valve seats so that's part of it. But really with the advent of CAD design in the 1980s, manufacturers have been able to increase tolerances and engineer and fabricate parts more precisely. Couple that with the much better quality and grades of oils available in the last 30 years and people following the proper maintenance procedures, most engines made since the early 1990s can easily run 150,000-200,000 miles or more without even taking the valve covers off. And they will still run smooth, strong, without misfiring, with all the horsepower they had when new.
Engines were required to have hard valve seats in 1971, because that was when cars were required to be unleaded gasoline compatible. By 1975, everything required unleaded gasoline. I think another thing that helped was replacing umbrella valve seals with positive seals.
You have the skills I'd expect of a fifty+ year-old ! You are a REAL MACHINIST not just a trained monkey machine operator, and that's about the highest compliment I can give you, as my Daddy was a machinist during WWII. My local engine machine shop may CLOSE when Guy retires because they can't get a young kid to learn to use the Sunnin honing machine correctly. Guy honed my 1964 SuperHawk block to .02 mm straight and true-ten times better than factory specs. When I put it together and started it, I felt it. Guy did a seven-angle cut on the valves and head like a Formula-One Race head. For you to do that QUALITY work on a TRACTOR engine shows your PRIDE in your work.
Crazy that that engine is 172ci. I work on V Twins that are almost that size daily. Lol You guys do great work, I put slot of stock in what you and your father have to say.
Where are you working on 172 CI V-twins? You realize 172 CI = 2819 cc's? I saw by your profile you work on motorcycles, a 103 CI harley is about 1688 CC's. A Milwaukee 8 107 CI = 1753 CC's
@@ttank1994 you might notice I said “almost” but 143 and 131 cubic inch V Twins are quite common these days. You probably just don’t know all that much about them.
My Valve “two cents”: I’ve seen a lot of very worn valve stem to guide clearances in a perfectly fine running engine. The beauty of a poppet valve is that it self centers itself in the seat as it closes.
Funny you guys call the core plugs freeze plugs, I grew up in the south and when we replaced them we called them core plugs...as they were called when cast at the foundry...however my father told me once of a john deere in Indiana they had during winter the water froze the core/freeze plugs were still in it while the block was cracked....lol
"As clean as when it left the Ford Factor" ... LOL ... most people still had outhouses when this was first made. I'm thinking you did a better job. Enjoyed the vid.
The serdi does. Great job. I am curious though why not use stones? It's a standard 3 angle and stones or machine will do it the same way. I find stones are quicker than setting up the sunnen vgs-20 in the shop I work at. We only set up a head in the sunnen to cut seats for a high performance/output application when I want to get valves to a perfect same height and add as many angles as I can.
I saved a ford 4000 from the scrapyard that has the diesel version of the 172. Got it running but seems low on compression. Parts seem to be hard to find and super expensive. Trying to decide what to do with it!
How much does it typically cost to get this done I have a stuck valve on my 70's ford tractor and I am debating just selling as is or pulling the head and having a machine shop fix it.
Back in the day all this was common-place with highly skilled machinists everywhere.
It's great to see this skill level still at work 🥂

So cool you’ve learned this from your dad. I work in industry that gate keeps information from everyone else to protect their job
Ive rebuilt a few of those old fords. They don't die. Even with cracked heads, cracked blocks, they won't give up until the job is done.
It's nice to see exemplified a few generations later, young men blessed with the skill set, taking-up and doing the vocation.
I know nothing about machining but I love watching the skill involved in doing this. Great job!

First rate work! Just excellent - well done.
You should show how to use the clover valve lapping compound. Spinning it round and round to polish up the valves and seats..

Seeing those seats come in is money 💰

Thanks for the his "Guided" tutorial!
If I'm not mistaken I used to usually drive them out from the bottom. And drive them in from the top.
These are great running engines

try methylated spirits for coolant when you cut Aluminium for better Surface finish

Nice work, thanks for making the video. When your newly cut seat is not so pretty, do you ever touch it up with a stone?
Super nice work !
Nice!!! Keep up the good work!!!!
I learned long ago to always lap the valves.
what an amazing video!!! I'm so damn jealous of what you do everyday! man you are super freaking lucky bro
Inhale cast iron dust yup
Nice work! 🏆
could you have sleeved the original guide with .502 od guide or thin wall bronze
You make some nice Chips...!!!
Looks like an awesome machine I am old school still use Sioux Seat Grinder debating what brand machine is next.

Do you never get tempted to port them? 😀
I remember watching a video from years ago of someone repairing cracks in a head just like shown here in the beginning... same engine, possibly?
I love these videos
I’m surprised the owner didn’t have you replace the valve seats. I would have. My thinking is if your there, set up etc. then freshen it all up.
I believe those little ford tractors were mainly used for gathering eggs.
You are a machinist version of a Brain surgeon. You account for so much that other shops would just cut away.
I might have 1 or 2 extensions that are now used on my press🤔🤔🤔🤔
great content, nice work
nice djob dude
Nice hat!
I wonder if using a strobe light while cutting the valve seat would give a better view of the cutting process?? Would look cool on video too.
Have you had any customers ask for port work to be done to the old tractor heads to help improve power and flow
As technically your work is it would be nice to see the outcome etc the initial startup
The serdi does. Great job. I am curious though why not use stones? It's a standard 3 angle and stones or machine will do it the same way.

Pull the head it’s cheap enough to save
Ok now. Where do I send my head?!? I need a real shop that does the work right!
Have you ever done flatheads?
Curious. Old school here. Is hand lapping no longer done?
Not in our shop! Lapping is an outdated process. There is no need with the better machines of today!
Can a lap compare with a MIRROR finish?
Is it ok to hammering on that machine, if you made precise machining on her?
....YOU'RE BUSTED-(?)
Will y’all work a set of heads for a race motor?
Wonder why no valve stem seals on the exhaust valves?
guess I'm confused about "umbrella" style valve seal usage. Only on intake? Why not both? Why either?
I’ve just started working at an engine recon shop in Perth W.A.
I’m wondering why not just use k line inserts?
