- Installation of remaining valvetrain components, then getting the covers put on the engine. The crankcase is now completely sealed up, and the engine is ready for a coat of primer to protect the clean metal.
Watching this over 5 years later and it's amazing how far you have come in terms of video production and your current "ease" of being in front of the camera.
That was a great engine, always started and NEVER wore out, tons of power and drank fuel, would use 30 gallons a day, we had 2 of them, one in a U with a hand clutch, the other in a 445.
Lots of afterthought with that engine, Over complexity at it’s best. No wonder they went out of business. Your average farmer could not work on that machine back in the day.
HELLO from Las Vegas Nevada
5 years later 😊
GOD BLESS YOU AND YOUR FAMILY
Your videos are not boring at all! In fact I think you're really an inspiration source.
@@squatch253 Well...I should be editing one of my own videos, and I'm a JD guy, yet here I sit binge-watching this M-M assembly series. Your presentation and mechanical skills transcend make of machine. I'm here two years late, but I'm really enjoying this. Thanks.
I agree, not boring at all! You must be lucky to have a picture of the original tractor to be able to go off of. Especially because it's a prototype
Thanks for these fascinating videos! You are doing a great job and I can't wait for the next one!
I think you ought to teach a class at a junior college or trade school. Your experience and insight would be worth tuition $$$$$!
Many engines designed in the forties and fifties had very long push rods. Not only tractor engines, but auto engines as well. This, along with generous rocker arm clearances, would seem to induce a lot of flexing and other monkey motion in the valve train. I can only guess that it was cheaper to build it with long push rods than to raise the cam up in the block.
Awesome video! None of it has been boring !
I really enjoy the videos! I’d be really curious to see how you clean parts so well-that engine looks the same now as it would have on the assembly line back in the day
What a great find moline crawler looks like you enjoyed the process didn’t pay much attention when I first saw it kinda glued to it now good job
Explaining what you are doing and why makes your videos enjoyable as well as informative. The engineers did a lot of experimenting and you are leading viewers through the mystery of their modifications and possible reasoning. Thanks for posting.
There probably was a diesel prototype, but was most likely cut into many pieces. It may have been the tractor parked behind it in the photo.
Good Video! Those push rods don't end! Is that a five or six inch stroke on this beast? I know you said this in one of your videos and the valve lift is massive.
Quite the mystery with the side cover. Gee, cast iron. That girl must weigh a couple of pounds, eh?
I overhauled an 830 Case gasser and put in a M&W high dome piston and sleeve kit in it. It was larger in diameter so it took the displacement to the 830 Diesel 301 cu in specs. As I had it on the dyno my instructor came over and told me to be careful not to push it too much so he took over and he took it up to 75 PTO HP and he decided he better back off. It had more to give but he did not want to ruin a new overhaul job. He said bring it back after a year and he would check it again but I never did. I did the diesel next and all I could get out of the that was 65. I love your videos. It brings me back!
We had one of those throttles on a Super M and and a M&W overdrive in a 47 M. Dad installed that for pulling a rotary hoe.
The engine casting look like they were sand blasted.
Good that you’ve documented this rebuild....careful work.
Boring?? NO WAY !!! BRILLIANT, Thanks
Those are some longgggg pushrods!
looking forward to painting
I'n not sure that you used the proper method for your jam nuts. Looking at 2:03, I see that you have the thin nut on top and this is in conflict with the following article. www.boltscience.com/pages/twonuts.htm
.010" and .018 " on a hot engine? That is a bit odd isn't it? Usually set valve clearance when cold to spec so when they warm up that is how much the expand and should have close to zero when warm no? That is what I am use to in my experiences.
Unless someone else has suggested it my guess is that the side plate was a stock ZB casting that was modified. The patch is to cover the original ZB oil fill/crank breather opening. but that i just my guess
I notice you don't use any gasket glue on the material gaskets. Is that not necessary?
Glad to see u stayed with the original side Cover
Good job and like all your stuff. I'm a machine nut and equipment operator and truck driver so it will all work somewhere. Thanks!
There are push rods and then "There Are Push rods"
I wonder if someone in the past thought an oil leak was from the now-detached covers, prompting them to saw them off; only to find out later that it was due to the damaged copper oil line.
Could be a hyd
Never boring
I noticed you don't use any gasket cement or glue. Is that your preference or not needed?
I really enjoy your videos.
just buy john deere
