Oil Seal Number for 310-8

Recommended Posts

Fiddlestix

I have a 1988 310-8 (21-10k805) that is drooling from the axle seal. These are clearly 1" axles and yes, a stock lite 300 series axle. I would like to replace these seals. I would also like to have the parts on hand when the event comes. Therein lies the problem...

The Toro Parts Viewer lists two possible seal numbers...100863 and 114677. I gives dimensions for the 114677 as 1"ID X 1-1/4" OD. Perfect! I have calipered the bore in which the seal seats and indeed it appears to be 1-1/4" diameter. The Parts Viewer @ Toro does not give the dimensions for the #100863 seal. Toro does suggest both part #'s available and valid.

OK, so we look at some parts lookup viewers of online sellers( Jack's, Mowpart) and now comes a problem. These viewers are showing both of these #'s and some give dimensions:

100863 Seal-Axle 1 I.D. X 1-1/2 O.D. 300-Series Only

114677 Seal-Axle 1 I.D. X 1-1/4 O.D. 300-series Only

When the 114677 is selected, I am directed to 100863 stating it super'd 114677.

What's the deal? Are there really two different OD seals for 1" axles and the or are the dimensions incorrect and both of these numbers are 1-1/4" OD? Which is the real deal for my wee little Horsey? :D
