Differential and seal/gasket questions

What would cause this?
Best place for a rear end gasket kit finals, diff, and trans?
What gaskets actually set tolerances?
Can I use rtv for ones that dont?

As guess the bearing froze up, spun, and galled the backing metal and bearing race. It's a short video but it doesn't look like the bearing is or has been lubricated.

One place for sure, Case/IH dealers. Might try the advertisers on this site. New Holland dealer if you have the IH parts numbers.

what gaskets actually set tolerances?
I don't know.

Can I use rtv for ones that don't?
I use black RTV on covers that just hold lubricant. Not under any type of pressure. Cheap, works well.
I have an excuse. CRS.

What's a good plan of action to fix the differential?
Or do I have to purchase one?

Unless someone has a better idea, appears to me that you need to replace the differential.

yes the carrier is toast, make sure the ring gear was not damaged also

A few well chosen still photographs placed inline rather than a pointer to a 6 second video would make it easier to help you.

It broke. Looks to me like part of the differential carrier is stuck inside the bearing. Possibly a failed bearing added slack that made it easer to break. The bearing failing and binding could have generated heat that led to failure. Hard to tell from a picture.

Multiple sources as stated. Gaskets are the least of your trouble.
Abryd09 wrote:What gaskets actually set tolerances?

None of them. Shims on each side and at the front of the lower transmission shaft set mesh of the ring and pinion.
Abryd09 wrote:Can I use rtv for ones that dont?

Sure.

As already stated, you need another differential carrier. Don't know without a closer look, but probably both carrier bearings. The carrier will no doubt have the ring gear attached. If you change the ring gear and keep your current pinion gear (part of the lower shaft), the gears are likely to get noisy(er). Once you get into changing the lower shaft, swapping out the entire transmission for a good replacement may be easier and possibly no more expensive.

That's not a removable sleeve in the carrier?
Probably going to throw it back together and save for winter project.
Does anyone have seal numbers that are Steiner so I can source them locally?

Go to your local NAPA with IH part numbers and they can easily cross them to their part number.

Hi,
Below are pages from the Cub parts manual showing the differential.

The piece of metal in your bearing is broken off the differential case. You can see the one on the right side in the parts pic.

JP Tractor Salvage at the bottom of the page can probably sell you used parts, the guys on here have said that they have good service.

TM Tractor has gaskets and seals for the transmission.

http://www.tmtractor.com/new/df/di_001newparts.htm

http://www.tmtractor.com/new/tr/tr_001newparts.htm

The side to side clearance of the ring gear has to be set with the shims shown in the parts pic, they are numbers 3, 4, 5, and 6 in the pic.

There are 3 oil plugs on the transmission case.
The filler plug is on top of the trans, to the rear of the shifter.
The oil level plug is low on the left side, fill it only to there, until oil comes out the hole.
The drain plug is at the bottom of the trans, visible from under the platform.

The trans holds 3 1/2 Pints of oil, until it comes out the level plug hole.
It is common for them to have water in them, from rain, or condensation inside the case, over time.

The 2 final drives have their own separate oil levels to check also. They all need checking to be sure they are not low, or the oil changed if they haven't been changed lately.

Below is the Cub service manual, the trans and differential are in section 6, I would recommend reading it before working on the differential. :)
