Winch seals?

[TWhetten]

I was checking the fluid in my winch and had to add a lot of fluid in the right side of the winch. As I put it in, the oil was running out of it as fast as I put it in. It was coming out from between the spool and the box. How hard is it to change that seal? Does anyone have a part number and a source? Also I was filling it with 80w-90 oil will that work?

-thanks Ty

V.P.W. has the seals I dont know the modern part #.s though, and here is a site that shows the rebuild of a Lu-4 winch (also used on M-37's)

John Deere Cornhead Grease will work if you don't want to take it apart. OD Iron also has the parts I believe as does AB Linn.

Thanks for the link, the pictures will really help. Thanks for the sources for grease too.
