Re-sealing a 1960 18h.p. gear case. It appears that swivel pin seal #304083 is N.L.A. Does anyone know of a replacement? Thanx in advance.

Someone on eBay has 3 for $9.50 free shipping.

I’ve also found suitable replacement in a kit like this:

Also Amazon and Harbor Freight, but this one on eBay I think is the cheapest.

I always use a little 3M 847 or similar sealant on that washer.

Thanx for the reply. I always panic and forget about eBay when I see nla. I think it early old-timers kicking in.

“use 307853 or Sierra 18-1034 18-7120”

Those numbers are for o-rings. Around ’64 they changed the pivot pin to have a recess under the head to accept an o-ring. The pin before that just used the flat fiber washer.
