Splitting Cub to stop oil leak

Postby ShawnAgne » Tue Aug 16, 2016 7:06 am

Cub is slowly leaking oil behind the oil pan on my 1952 Cub and I need to replace the gasket and plate so have some question.

1. Looked on the website but is there a good thread on how to split the cub?
2. Reading around it sounds like TST is the person that sells the correct plate and gasket?
3. Since I have it split is there anything else I should check/replace since I'm in there?

Many thanks in advance
Shawn Agne

Cut some wedges and drive in on both sides of the front axle to keep the front part of the tractor from tipping to one side or the other. If you haven't ever put a clutch in it this would be the time, TM Tractor has the cheapest one you will find with original type graphite throwout bearing. You will regret not doing it in a few years if you don't go ahead. Here's a link on how to.

Spend some time using the search function of this site. There are many variables; such as shop space, blocking/cribbing available, tools for lifting and moving the split portion of the tractor.

There are several posts on home made splitting stands. A shop crane/cherry picker will greatly assist in the split.

If you haven't split a tractor before, suggest getting experienced help.

Space is not an issue. My brothers father-in-law is a very experienced tractor mechanic so I have him to fall back on. Actually I think he has the shop crane and everything I need. The manual helped, but was also wondering about the parts.

TST is that the same as TM tractors for the crank case cover and seal?

I will say it wasn't the safest way to do it but it was the only way I had to do it. I split our '49 to put a clutch in it by myself using only blocks of wood and a floor jack. I moved the front end and had the back chocked and locked. Putting it back together was a challenge doing it alone. The block of wood is barely visible under the front end and on top of the axle. There is one on both sides and they are tight. Our son wanted to check it out, that's as close as I would let him get and he wasn't there for long! I just noticed the touch control is removed, I took it off to rebuild it at the same time. There is no need to remove it from the tractor to split, only the line to the pump. And no, TST and TM Tractor are not related I don't think. TM Tractor offers a new rear engine oil seal retainer for $184.90 http://www.tmtractor.com/new/en/377fp.htm

Tim Talleur is tst (forum name). You can PM him for directions and cost on the seal retainer and seal. TM Tractor is one of the Forum Sponsors and sells new and used parts, but not the reworked retainer.

While you have it split, take a long, hard look at the clutch and throwout bearing.

Also, shine a light down the tube and see how the transmission input seal is doing.

Ok so far have
1. New seal retainer and seal
2. Clutch and bearing
3. Transmission input seal
4. When put oil in the steering housing it leaked so replacing that
5. Oil ran out of the final drives so guessing I need to replace those seals also.

Since I'll have the hood off should i go ahead and replace the plugs too?

If the engine is running fine, don't worry about it. If anything just confirm the spark gap.

The only time I'd consider replacing plugs is if the electrodes have eroded or the plug is badly fouled.

If you do some searches, especially in the HOW TO section, there is a lot of info on rebuilding assemblies like the steering gear housing (upper "bolster" and lower) and the finals.

Before you tear into the finals, however, you might check the transmission gear oil level. Quite often it gets overfull due to either the owner overfilling with gear oil, or condensation getting in and raising the oil level. The increased level will cause leaking at the differential seals, and can mess up your brakes, too. In either case, remove the small plug on the left side of the transmission block, near the left brake rod. This is the "FULL level plug", and if oil/water come out, it is overfull. You probably should go ahead ahead and drain the transmission (plug on front bottom of block), then refill with gear oil...only 3 1/2 PINTS. PDF Manuals above have procedures and quantities...free downloads.

IF the seals ARE bad, there is a HOW TO for SAFE removal and rebuilding. Good luck!

Dale,

Actually after I drove it around and noticed it leaking this was one of the first things I did. Drained the oil out of the finals, hoping to see water and then changed the gaskets on the gear housings. Refilled per instructions and it still leaked. So I'm guessing it is the seals on the finals themselves?

Also on the stearing unit up front when I removed all the grease and filled with oil the oil leaked out. Should i just replace the gasket at the bottom or the one attached to the steering wheel rod also?

The hole goal of this is just to go in and get everything replaced so I know the age and don't have to keep going in and doing one thing at a time.

Thanks for all the help, very much appreciated.

Shawn

This leak could be the oil seal where the shaft comes out the bottom of the steering gear assembly. If you clean it all up good you might be able to see where the leak is coming from. I've not used it but some have suggested using corn head grease in lieu of oil for this lubrication. I is supposed to not leak out as bad. Stan

The fluid level to which I referred is in the transmission, not the finals. IF the level of gear oil is too high (capacity only 3 1/2 PINTS), fluid can leak out the seals in the differential. This can also "goo" up the brakes and make them more ineffective than normal!

Here is a link to the LUBRICATION Guide from the Owner's Manual, that discusses servicing the transmission.
http://farmallcub.com/rudi_cub/www.cleancomputes.com/Cub/Cub%20Owner's%20Manuals/International%20Cub%20and%20Cub%20Lo-boy%20Tractors%20Operators%20Manual%202-75/Page-71.jpg
The plug I spoke of is item #29: The OIL LEVEL PLUG

And here is a photo of that plug on the LEFT side:
20160401_150041 (Small).jpg

BTW, the seal you see where the final bolts on, is the seal where the gear oil would be leaking. Just outboard from that seal is the brake. IF you remove the final, go ahead and replace that seal while you have it off. There is another seal for the axle, too. If that one is leaking, the oil can often be seen running onto the rim.
