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 🥂
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!
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.
Thank you for watching! We don't plan on going anywhere!
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.
Really good cam angle shoots. Clear as could be, and you showed the perfect removal of material.
Thank you! Working on stepping up the filming!
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.
Nice comment ✌🏻
It's awesome to see this kind of attention to detail and technical skill being applied to keep these workhorses running.
notification squad, happy easter!🔥🔥🔥
Great video and excellent close up footage of the valve seats being cut 👍🏻🇦🇺
I am always impressed by your high standards and quality work. The videos are also superb.
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.
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.
So cool you’ve learned this from your dad. I work in industry that gate keeps information from everyone else to protect their job
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.
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.
Method with an explanation in plain English is awesome 👌
Great job guys
I know nothing about machining but I love watching the skill involved in doing this. Great job!
Great commentary and camera shots; thank you.
Interesting tube and thanks for explaining the way the Serdi locates the cutter 👍
Nice job!
Everything I've seen todate has been "Top Notch"!
Good camera work. Am impressed with how clean the shop is. Usually the walls behind the equipment have layers and layers of oil on the,.
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!
I'm glad you were able to locate a better core on short notice.
Sure wish you guys were near the New Jersey area. The attention to detail your Father and yourself is exceptional. Great work as always.
there's always FedEx
First rate work! Just excellent - well done.
Thanks for sharing 👍 and Happy Easter to you and your family.
Hey Jimmy, Glad I found your you tube channel.Machine shops are disappearing at an alarming rate. Give me a call sometime at RTP.
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.
I never knew I wanted to know this, but now I can't look away!
I have watched so many of these I should be able to do the job...lol.. Love to see the precision measurements and cutting.
It's nice to see exemplified a few generations later, young men blessed with the skill set, taking-up and doing the vocation.
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.
Best content and presentation on youtube.
it's pretty cool to see what actually goes behind the scenes in a machine shop
Thats a treat to see.
Nice work !
could you have sleeved the original guide with .502 od guide or thin wall bronze
You should show how to use the clover valve lapping compound. Spinning it round and round to polish up the valves and seats..
Excellent work! Well filmed too.
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
AWESOME WORK....MOPAR 4 EVER.
Well trained technican. He knows what he`s doing.
Nice work! 🏆
Nicely done.
You guys do good work!
Super nice work !
Used to work in a machine shop and man I miss working like this.
Nice!!! Keep up the good work!!!!
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?
Nice job young man, very nice 👍
You guys have come a long way
Seeing those seats come in is money 💰
BFH works every time!
Thanks for the his "Guided" tutorial!
These are great running engines
If I'm not mistaken I used to usually drive them out from the bottom. And drive them in from the top.
great content, nice work
Great stuff
Beautiful 👍
I used an expanding pilot sometimes... on weird farm stuff sometimes.
try methylated spirits for coolant when you cut Aluminium for better Surface finish
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.
Held lubrication better
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 make some nice Chips...!!!
I love these videos
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
Man you nailed that head
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 remember watching a video from years ago of someone repairing cracks in a head just like shown here in the beginning... same engine, possibly?
Good job... 😀
Looks like an awesome machine I am old school still use Sioux Seat Grinder debating what brand machine is next.
Serdi is amazing!
nice djob dude
"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.
I might have 1 or 2 extensions that are now used on my press🤔🤔🤔🤔
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.
When you were cutting the seats how much of a cut do you usually end up taking to clean them up?
Do you never get tempted to port them? 😀
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.
Nice hat!
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.
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!
I’ve just started working at an engine recon shop in Perth W.A.
I’m wondering why not just use k line inserts?
I learned long ago to always lap the valves.
What would you suggest to loosen seized flat head four cylinder case tractor engine? Or are they even worth it?
You are a machinist version of a Brain surgeon. You account for so much that other shops would just cut away.
Sounds like you guys have a lot of communication with the customer.
When he said plumbus I instantly thought of Rick and Morty lol awesome video tho
Cool
As technically your work is it would be nice to see the outcome etc the initial startup
Have you had any customers ask for port work to be done to the old tractor heads to help improve power and flow
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.
How can i get some custom rods? I have a 20r with 22rte pistons, & newer 85+ 22r are shorter pistons.
Wonder why no valve stem seals on the exhaust valves?
Do you really find that pfl actually works? Or does a fluid like wd-40 or just some oil work almost as well?
if the customer went with the option to completely replace old valve seats with new ones, how much extra would that cost?
guess I'm confused about "umbrella" style valve seal usage. Only on intake? Why not both? Why either?
I believe those little ford tractors were mainly used for gathering eggs.
Is it ok to hammering on that machine, if you made precise machining on her?
Nice job 👍
I have 2 questions. One do you or can you do motorcycle heads if I supply the parts, and would you do this with me shipping the head and parts to you??? I'm currently rebuilding my 99 honda CBR 900rr and want the head decked and new valve seats installed. I will reassemble the head I really just need the valve seats done most of all.
Will y’all work a set of heads for a race motor?
I didn’t see you lap the valves in, was that done off camera or is it not needed? Just curious
So are hardened valve seats not necessary with unleaded fuel in these old tractors? My 1955 JD Model 60 will need rebuilt at some point, I’m bringing it up to you guys. I am in Southern Colorado
I think the general opinion is they're not needed unless you're working it long and hard all day every day like they did when new. For the occasional use we'll put on the old tractors the benefit of hardened seats will never be seen.
