Super C transmission gone out?

[madscotsman59]

My 53 Super C won't move now. i was digging gravel with the front loader and i pushed the clutch in to reverse and put it in gear then let the clutch out and nothing moved. I Thought maybe a gear tooth let loose and it was sitting in a gear hole so i moved the wheels a bit and still nothing. I'm hoping somebody will tell me theres a simple shear pin or something that won't require breaking the tractor apart to fix it.

Clutch?????

Clutch?????

The clutch works fine, it engages the gears in all speeds and reverse but when i let the clutch pedal out the tractor doesn't move.

Just a wild guess, but, thinking you may have snapped an axle, or stripped the splines at the end, that go through the bull gear.. Easy way to tell, is to put it in gear at a lower throttle setting. If your brake pedals are locked together, unlock them. Then, easily apply one brake, or the other. If it does move, the side the applied brake is on, is the side that's broken.

Like an "open" rear end on a car/truck, it will power out to the side with least resistance.

I'll check that out this morning. It's low on gear oil i think, but i wouldn't think that would keep it from shifting or moving.

 

[madscotsman59]

You were right, i tried the right brake side and it pulled a little but when i tried the left side it wouldn't budge. Now comes the fun part. Thank you.

Well it's mid afternoon and i managed to take my truck and pull the tractor back up to the shop and started stripping stuff out of the way and got all of the bolts loose except to two rusted ones in the front of the toolbox inside and started spraying rust buster on them every hour till i'm satisfied they are soaked good, then in the morning i'll try to tighten them slightly then if need be toast them with the torch then try to back the nuts off. Then i'll see what's going on. Hopefully it's just the lock nuts have backed off the gear and it moved out of position.

 

[madscotsman59]

just one quick question if there is anybody still out there...is there anything else like the shifter that needs to come off before i can get the transmission cover off? I Have all of the bolts out including the ones inside the steering pedestal. but it is hanging up on something when i pry up slightly in the back. I Don't want to pry up on the cover too much because it might snap in two. That would e my luck. I Could see inside with a flash light and the bull gear is in place and looks o.k. but without getting the cover completely off i can't tell.

 

[DJ54]

I've never had the cover off the Super C's, but have taken one off a H. Pretty sure there are dowel guide pins in either the cover, or diff. case. That's been 35 years ago,so... Anyway, it will have to come pretty well straight up. Not nearly as heavy as one on an H, or M, but probably still a pretty good chunk.

 

[madscotsman59]

Well i finally was able to get the cover off of the trans. and saw the right bull gear laid over with a sheared off axle chunk clinging on. So now i have a ton of work to do to get the axle housing loose. sheesh. All of the half track equipment has to come off. A ton of work for me. Oh well...gotta do it.

 

[DJ54]

I don't envy you on that job. Looks like those tracks are a little rough on tires too..!!

I saw a Farmall M once with the bull gear showing through the slot it had ground through the housing. In fact I once bought an M that had apparently done the same thing and had been repaired. It had what looked to me like green body filler over the weld. Good luck with your repair and, I'm glad your Super C didn't get that far.

 

[madscotsman59]

Actually they save the tires a lot of wear and tear. Believe it our not there is no vibration.

 

[DJ54]

I just saw those big cracks between the bars on the tires. Looks like it's pulling the tread, right off the casing.

 

[madscotsman59]

They are the original tires best i can tell and i don't doubt they are due to fail but they still make new ones and i have two waiting when they decide to "retire" .

 

[madscotsman59]

now i need to know how the axle comes out of the housing. is there a retainer clip on it?

 

[DJ54]

Axle comes out the other end of the housing, but first you need to remove the end cap. Axle is larger in the center, and machined for the bearing to fit over the splined end, and the outboard axle size. Here's an exploded view of it, from Case/IH online parts store. Pretty simple, once you see it. Official Case IH Online Parts Store and Case IH Catalog for Best Parts Search and Best Parts Look Up. Case IH Parts for Case IH Tractors, Case IH Combines, Case IH Tractors, Case IH Manuals, Case IH Parts

It looks like you have the bearing retainer removed on the inside, so, once you remove the outboard axle end cap, it should tap right out.

 

[madscotsman59]

Thanks..I Think these bearings and shaft are original. The bearings are corroded a little to the axle even with a gallon of grease and oil surrounding it. When i first broke the housing gasket seal about a cup of water came out from either condensation or top cover bolts collecting water in their little mini funnels. I'll fix that when i put the cover back on.

 

[madscotsman59]

Yep, the axle and bull gear are damaged, so i was able to salvage the two bearings though. They are good and tight and roll for a long time with a good spin. So now i'll need three gaskets and a piece of rubber tubing and two hose clamps (guess where they will go) and a tube of gasket sealer and some heavy oil. I'm thinking 90 weight.

 

[madscotsman59]

Now i'm having a little trouble finding the inner oil seal for the axle housing. Case/IH says it's out of stock and when i tried to find one using their numbers i get nothing. I Have the outer seal installed but can't find the larger inner seal. The number i have is 380768R91
i have a 1953 Super C btw. I Bought the outer seal on EBAY and it fits fine.

I did a quick Google search, and seems to be quite a few out there. Even one OEM on ebay. I also used the Timken number in the ebay ad, to look at NAPA, and got a hit. The ebay OEM seal is the least expensive @ $21.95, but who knows how long it's been on the shelf. I have no idea what shelf life is on these. NAPA stocks them for $25.99, although they may have to order it from their regional warehouse, for your location. Here's the link to the Google search. 38768R91 - Google Search
