Posted: Fri May 30, 2014 3:13 pm Post subject: Oil Pumps
Hi,
I received my NOS oil pump in the mail today. I learned that there are two different oil pumps: the early style and the later style. The one that failed in my engine was the early kind and the NOS one I received is that later style.
2 questions:
1) Just to make sure - these can be used interchangeably, correct? In other words I can use the later style on my engine?
2) Please take a look at the pictures: I am pretty sure the NOS I received is damaged and has a piece broken out of it.
As I recall there are at least 3 versions of the pump. All three interchange. But make sure the gasket you use fits the pump. The pump driven gears differ in that the early chain drive engine cam gear is angled one way and the later gear drive cam gear engine is angled the other way. _________________ Wes K

Ryan's book lists two oil pumps on page 55.
Both pumps I have are gear driven.
I am still hoping for answer to my second question. In the second picture you can see that it looks like a piece broke out of the flat bottom, right between the mounting holes.
Is it broken?
I couldn't discern the condition based on your photos. Need a clearer and larger file photo. _________________ Wes K
