So I learned abt this series from your last video regarding the D2 rebuild success etc.. I'm kinda enjoying this series You def need to tidy up your main ytb page !
Man, what devastation inside that casting. Would there have been any way for the operator to foresee and / or prevent that clutch dog from coming off and destroying everything or was that something that was just going to happen after a certain number of hours had been put on the machine?
I know old Farmall M's would crack a case if a ball from a rear axle bearing got in between the bull gear and the case. I think that was fixed in the Super M tractors. There are a quite a few Ms with patches on the rear end case. That live power clutch lever is a little bigger that a M rear axle ball bearing though. Great video.
Squatch253 Maybe the roller bearing was better on the Super M and didn't give troubles or there was more clearance between the bull gear and the case on that unit.
LOoks like you've got another dandy but it'll be fine. You'll fix it. I know what you're talking about about the spline being twisted. I swapped a Troy Bilt for 2 Gravely walk behinds. Had one about ready to run when I saw the main case was cracked. And those guys you found did a dandy job on the M&M. I ended up swapping all the guts from one case to the other and had never turned a tap on a Gravely before. Pulled them down and the good case had a splined shaft run through the middle with 3 sets of splines on it. The 1st was hi/lo, the next was fed/rev and the last was the P.T.O. The best I could figure was a bolt fell out of a quill shaft and locked up the p.t.o. or fwd/rev at speed and every spline was twisted about a 1/16th. Tough is all I can say. You probably know the insides of a Gravely better than I do the outside. Got 2 left, both with 301 Kohlers. Man killers. Take care and happy Daddy's day!
That'll be fine. It's like Brian Block dropping that big drill (7 tons I think) when the hoist cable broke and breaking the motor and gearbox off of it and trying to weld it all back up, being cast. Cracked a 10 or 12 inch slab when it hit. Fell 2 feet. Glad yours is on the floor!
It's actually interesting to see all those castings like this, compared to other brands as they make rear end casings in many pieces. Then bolt the axle trumpets and brake housings on instead of it all being one huge cast lump like this. It don't take a lot to break some diff carriers , I've seen guys even snap a heavier duty carrier that was fitted to 1970's Leyland/ Nuffield 10 speed skid units in backhoe loaders built by JCB . I'd bet from the amount of work in fixing that casting, I sure didn't want the bill after but good work costs good money unfortunately.
@@squatch253 Thanks for the reply Considering what that prototypes worth "If" it ever came up for sale that is cheap. I'm going to guess if you realistically priced your time and tooling in thats still a 5- $6000 + repair, yes I get we do this restoration stuff for fun not an hour rate, or much chance of seeing all the money back on average common machines . I have this discussion with my parents when I repair machines on our farm . If I did that for anybody else it's $50 an hour through my business, Technically they are costing me money as i'm not there doing the paying guys job sometimes. our Min wage in Manitoba's around $11.75 an hour for employed workers "pumping gas" or what ever. Really we should be working minimum on that kind of figure an hour here for our farm even then it would be cheap labor I was getting $14 on somebody elses farm 10 years ago and not financing any of it !.
You might contact Jay Leno at his garage, he has a company that has repaired cast blocks that have been deemed unrepairable by every one else. I have seen some of the work and it is good. they repaired the block in an old fire engine he was working on. I don't know what they charge but if it is a one of a kind block they will fix it. I hope this helps................
It's a brave man that successfully repairs cast iron.
5 years in the future, this section is now shiny and wonderful
Finally found this video. I love the damage assessment. I used to do it for on A/C engines in the Navy.

You def need to tidy up your main ytb page !
Wowzers. You’ve certainly gotten yourself into quite a project. I’m binging the episodes :)
Your drive for absolute perfection is admirable.
Good detective work,it makes perfect sense,shame the previous owners beat this unit so badly.

sucks that it happened but nice to see getting repaired and saved...awesome job
Thank you for taking the time and effort to preserve and restore these irreplaceable pieces of MM history. Love your channel!
Thanks for explaining the details of the damage and repairs.

@@squatch253 That seems like a really fair price considering how much welding there is and how well it was done.
