Does any one have the dimensions of the rear hub oil seals for a WC ?
I need to purchase two but don't want to strip her down till I have the  seals in hand, I know I can purchase from the US but customs charge an arm and a leg and it takes forever to arrive across the pond.
I have checked all the manuals I have but can't find mention of sizes !!!

Thanks for your follow up much appreciated, I seen these measurements also on DJS web site but they don't make any sense to me ? I hazard a guess that the pinion shaft is no more than 2" in diameter !!!
My problem is oil is leaking from the diff and running down the tyres telling me its the pinion shaft oil seals need replacing, I am guessing the seal dimensions you suggest go somewhere else ??

The seal goes on the outside of the hub.
 
See the picture.

you need the inner pinion seal then not the final drive seal.

agco # is 70202602

crosses to skf #19407

Stock Number 19407

Description LDS & SMALL BORE SEAL

Lip Code Nitrile (Lip Code: R)

Type/Style CRW1

Inches Shaft 1.938
Bore 3.189
OD 3.194
Width 0.313
Weight 0.125

parts book also shows some kinda of inner seal that is different on steel rear end models.  im guessing this was a 2 piece seal and the former has replaced it

Thanks Carl
Yes I noticed after I messaged you today that I had made a big mistake by saying hub seal.
Anyway we got there in the end, many thanks for the dimensions hopefully now I can order the seals !! how does one remove and replace the inner one ? is it through the top of the brake casting ? I am sure all will become clear once I strip her down !!

Thanks Garry, I was not even aware there was a seal there, deft not one there now !!
I am guessing its to stop dirt etc from getting in  rather than oil out ???

Is the same seal used on both sides of the brake chamber on the pinion shaft on a WC?

National oil seal part # 450094 is the same as agco 70202602 . Also a Dodge truck (late 90's early 2000 maybe) wheel seal. Most auto parts will have them or can order. I replaced mine last winter and discovered this. The national seals actually fit better than the agco did on my wc.

Takes 4 on s# 86405 and prior. Only 2 after s#86405. According to the parts manual.
