I have completely disassembled my wc all but the rearend should I pull it apart and replace the seals? How hard is this to do? Also can I find a factory made cover to replace the cultivator lift?

Call Brenda over at Sandy Lake, she will price the seals, gaskets and may have the cover for removing the mechanical lift.

On my 1934 WC which i restored in 2009 I replaced the donut seals on it, and I got them through agco, they are no longer cork, but rubber now.

Thad, it's not hard, just expensive. Those big side seals are a bit over $50 each now.
If it were me, I'd go ahead and do it now before you paint

I am resealing mine now, I got mine from Sandy lake. I am replacing the big donut hub seals, both inner axle seals wich seal up the brake drum are from the differential side and the final drive side. When these leak it drips out the holes at the bottom of the axle knees where the hub axles are mounted. Every WC I have seen leaks there.There are cork gaskets between the big round bull gear plate and the cast housing and a gasket for the final drive cover that holds the donut seal. One of the inner seals requires a steel adapter because the hole back in the axle housing is about 2 inches bigger than the new seals. They are $60 a side, donuts $50 a side, I think I spent a little over $200 but I am making the $60 adapters myself. All these parts are probably about $300. If you are going to restore and paint it is definately worth the money. You will regret not doing it after you paint and oil is running all over it causing it to lift your paint, I know from experiance. I find it amazing that agco still offers parts for 70 year old tractors. JM

Thanks for the input guys. I already had oil leaking out those holes below the brakes when I bought the tractor but I just wasn't sure where it came from. My I&T manual with 96 pages and covers 10 different tractors needs to be replaced with an original with more detail.

Go to agcos web site you can look up the part diagrams and part numbers.

Another vote for Sandy Lake.
Also, save your tin retainer as the new ones I got were slightly larger and wouldn't fit.

Thad ,The manual calls for 250 wt oil in the finaldrives-- I couldnt find any so I made some thick stuff using no2 grease diluting with 90wt gear oil.  HTH Mark

Do you have a part number for the seal that goes between the differential and the brakes? I can’t seem to find it at any auto parts stores because it’s such an odd size.

Welcome to the forum lee. We have lots of parts for these tractors. I’ll take a look for seals

I still have a few NOS seals available that are the large OD that do not require the spacer

If it was fun to pull in LOW gear, I could have a John Deere.
If you can't make it GO... make it SHINY
