1086 oil pump

gbs · Jul 5, 2015

what is the part# for the drive splines on the crankshaft that drives the oil pump,i can't get case ih parts site to work for some reason,also ran into an issue with the front seal it was bearly touching the end of the balancer hub on the old one so I didn't install the new seal all the way to the bottom of the housing and now it's also leaking ,are there different width seals available this one needs to be 1/4" wider to go far enough onto the balancer hub

The splined pump drive is 675304C1. I have never run into a seal not contacting the surface of hub properly but I have run into the wear sleeves that were too short to fully cover the hub. Something you have to be careful of is that the key does not crawl out of groove and prevent hub from fully seating. It should have a key with shoulders on it so that can't happen but it might have a regular half moon key. Seal has to be flush with the face of pump. Just cocked .020 will possibly cause leaking seal.
