[kram1976]

I was going to order all OEM parts but some of the bearing are not available from Kawasaki anymore. Who makes the best aftermarket kit. I am in the process of rebuilding 4 pumps and I want to use the very best bearings and seals.
Thanks guys.

OEM or aftermarket, life span of an ultra pump is around 60hrs. Only thing I found to extend them alittle is to add alittle gear oil before closing up.
