Title: Oil pump assembly
Post by: 1976RD400C on August 04, 2020, 02:58:06 PM
Does pin #11 supposed to stick out of only one side of the plunger shaft #9 or should it be centered in there? Mine just sticks out one side and it hangs out enough to interfere with the seal #13 mounted in case cover #2 as it gets reassembled. The pin seems to be a tight fit in the shaft. Thanks.

Not centered. Sticks out but will clear the seal with a wiggle on way in. Don't forget the grease on outside end. :metal: :cheerleader:
