Hearing a .110 off of the cylinders kind of made me cringe a little, fearful of water jackets. At that point, I was almost sure that you'd do a bore and sleeve to bring it back to original spec.

Oh that's nothing. In the 50s, Up to .010 wear you could hone the block knurl the pistons install G I spacers and a new set of rings, be good as new !

Really $25 for this round me in rural blue collar mn this would be hundreds

Heckter was the Old dog in the funny pages in the newspaper, way back in the day. Remember news papers ? They had a comic page with Dagwood and family. Plus, the family dog that got in trouble all the time. Hecktor was his name. I think he was 20 + years old.

My dad's kubota engine had overheating issues and I found that the radiator was plugged up. The fins in the radiator were very thin. Dad used well water for coolant. He was on a farm with lots of minerals in the well water. kubota will not sell radiator parts but sold us a new radiator for six hundred.

Turbo cars by pass the that pcv stuff as well 22:17

That would be so cool to see that getting put into that D17 Allis Chalmers also seeing how you all know about doing it, making all of the different mounting brackets and The parts and pieces you're going to need to make the Alice transmission to work with. The Chevrolet engine, the spacer adapter plate plus also I would imagine, also, Hey, some sort of Spicer for the flywheel. It would just be a really cool project. I would love to see it

See your sucking gunk in the motor like that leave it open 21:47

why wouldnt you use a carbide bit in a lathe and just skim the schmoo off then dress the journal?

Depends on the customer and his sentimental nature… a lot comes into play. Matching # motor, the build of the car original or resto-mod, budget, parts availability , etc…

Happy birthday 👍 What you commented about fixing a mess up? This is the DEFINITION of experience ❤️ Not panicking and knowing a solution so no-one ever knew. Often getting something better in the end. My old boss used to come up with sayings Doesn’t look right? It’s wrong. No iffs, no buts. Buy well buy once. (Tools) plus look after your tools and they’ll look after you. I laughed as an apprentice electrical engineer in early 80s. But I remembered and it was great foundation for life basically, though Frank didn’t realise it. I had to retire with Crohn’s and it’s add ons inc liver failure (Primary sclerosing cholangitis (PSC) ) But I have heard myself repeating these sayings to my son. What you are fixing will be to far higher tolerance than original. Add, it’s a tractor, how can we cut costs etc and if it breaks they’ll buy another? Now retired I am getting more into engineering best I can. I fix stuff people gave up on. Love restoring old machinery. 1940?30?50? I wish I had been diagnosed ADHD in 80s instead of being pushed into more academic to start. ADHD fckd it up. Being clever and able to think outside the box meant nothing then. You had to conform to society norm sadly, so time keeping when you have no concept of time doesn’t really work for a start. But I could do 10 h work in 6-7? I found electrical engineering interesting so I excelled with distinctions. Not so in school. Realisation and why after diagnosis has helped so much. It’s not a disability? It’s an asset. But, I needed a long leash. I invent stuff now also lol. This is UK btw. Love your channel Keep it up 👍 Btw, what dog do you have? I noticed the bowl. I have Leonbergers, like GSD colour Newfoundlands? A rough description.

had to laugh at "today's standards". boy, todays engines aint gonna be around in 100 years like this one

Mando 440😊

Most Fuelie heads I've worked on already had 2.02/1.60 valves. Nice work on the oil plug problem! I may have tried to drill and press in a sleeve, re-drill the oil ways, then tap and plug the sleeve.

Please show that you cleaned all threads with a tap. Many miss this step.

Over heating makes that to happen

Sounds like Kubota wants to sell engines not parts.

I wonder why my 1930 cadillac V16 has not counter weights . I discovered it when I took off the pistons to replace them with much lighter aluminum ones . I guess I won't have to rebalance the crank ?

Putting the wax back to follow thru on the dad joke is top tier 😂😂

Nice video. For the exctraction of the old seats we now use the Newen Tug-Gun and it works great. No heat on the head, no injuries with the Cummins slide-hammer type tool. It's a compressed air puller with a pedal. For the insertion of the guides, it works great with dry ice to freeze them beforehand and a zipgun as the insertion tool. Goes in real easy when frozen that cold. For machining we have a SERDI CNC machine that cuts like a vertical lathe all 3 angles one after the other on a couple passes. Do you lap the valves after machining? We do so to get a perfect fit and vacuum pressure test each one after.

How about you making your one from brass bar ? You say you are an engine just make them you will no it makes the job easey.

I think you made right decision for now, based on your options. Perhaps could have considered just replacing the 2 overheated rods, if the other 2 were good. I hope the manufacture rep finds the mistake, and makes it right, for you and the customer! Let us know what happens! I'm thinking🤔🤔 the spec for the finished bushing size, was somehow mis transposed as the pin size, then added oil Clerance to it...🤔 Thair rods are correct because the bushings are original production. I'd also want to flow test those water jackets, and or look in them with a camara, and compare to the others. Same with the head, looking for an obstruction, or casting defect. Also check the head gasket, could it cause an issue if installed wrong, or does it seal off any of the jackets? You could also be right about posable dirt. One more thing, take that Ball bearing, machine a flat about 1/4-th or so, leave a 3/32 pin sticking out. Then drill into the mic tip (with a diamond bit if necessary, or torch it first), press and superglue the piece you made in. Then machine the other mic end until it zeros out. Yeah, you could buy one, but not as much fun!!! You guys are doing an excellent job with this content! Mutch appreciated!

$ you can buy connecting rods for a top fuel dragster for less than$ 500 ea. see this from online racer One supplier of custom-made titanium rods said titanium rods typically cost $425 to $450 each, or about two to two and a half times as much as a set of quality steel rods.

Asking respectfully but would that valve impression on the piston head cause a hot spot or stress riser? I don’t know but was surprised to hear you say it didn’t hurt anything, as though you would reuse it. 😊

😮

Tell me why you couldn't obtain oversized bushings and machine them to the proper size while center to centering the bushings? We used to do ot all the time at the Crankshaft Co I worked for.

"Hone cylinders to the next oversize" Surely that shoud be rebore and hone?

Excellent video. More than just engine work going on here.

I have had to machine dowel bushings/buttons for many various applications through the years. I own a transmission shop and often times vehicles come in missing the dowel pins because other shops omit, lose, or delete, them not realizing how important they are. Most dealerships don't have them on the shelf for sale so I'm forced to lathe cut them from drill rod.

We had a Ajax engine operating at a well site in this area. 4 cylinder, horizontally opposed. 2 cylinders on one end were engine side, 2 cylinders on the opposing end were compressor. Entire unit was about 8 ft long and 4 ft high. Would have loved to tear it down.

This video is super helpful. I have a 235 in my 51 Chevy 3600 from a 56 Bel Air. My motor bent all the intake push rods during the first run in over 30 years. We suspected bad gas gummed the stems, but I think too tight a stem/guide clearance was actually the issue. Tear down revealed that the head had recent machine work. I had the engine re-rebuilt in 2024 and have not run it yet. I'm 1/2 afraid to run it. I think my shop cross hatched the stems and put umbrellas on it as well. Also, worried about good oil drive/distributor engagement. Definitely going to look at some things before first run.

So the block is shot?

You can weld it and rehown it 38:54

I did 50.000 km

4 bolt main I stead if a 2 bolt 28:09

Very informative video where things get explained clearly and also working with your father who is extremely knowledgeable and makes for a very pleasant show to watch.

A suggestion for a replacement engine: The Pontiac Iron Duke, which was used in the Pontiac Astre (their version of the Chevy Vega) and many subsequent models. Hopefully there are some available in salvage yards

You hope men like this have many sons that can step into their shoes one day.

drill a 1/8 0r 3/16 hole twist a counter thread in and make sure its seated and has a good bite then drill it out. " only way to remove a roken bolt " lol

My guess is that motor will never be apart ever again.

I Love That Clean Up Guy!!! I Lost Mine When He Was Training Me To Twist Wrenches At The Tender age of 9. But I Like You Loved Working With Him!!!

Ive worked on allot of propane forklift motors and some cng autos. Ive always been amazed how clean and wear free everything was. This must be the bunker fuel of cng.

I worked eight years in a performance engine rebuilding shop. Had bearing shells mixed up in brand new boxes. Had standard rings mixed in with +.030 rings in new boxes also. As you know, you have to assume it's the wrong part, until you prove to yourself that it is correct.

Give a man a grinder and he will de idiot proof anything.

When we have hese kind of problems we buy external oversized bushes and our rectiffier shop (like you) gives the exact diameter he needs by rectifying the external surface. We are in Uruguay

Old iron

Interesting repair. I have seen stitch repairs done but never in this heat-soaked area of an engine. I think it’ll work, as you said, likely the first area of failure if the engine overheats again.

Wax does work moe better lol

How come no one ever uses an EDM (Electro-Dynamic Machining) rig to remove broken bolts and taps. It's like a spark erosion drill. No welding, pounding, or magic fluids required... Oh, that's why. Goobers.

What’s Really Disturbing is He Just Wants The Bolt and Tossed The Engine Block 😮
