Thread: Oil pump drive shaft

Tweet

It looks like I probably screwed up when I installed the standard oil pump after I removed the high output version that I originally thought I needed. Since I was laying on my back that time too and only lowered the pan enough to snake the pump out, probably (most likely!!) got the drive shaft back in upside down, then when I primed the engine last weekend, pulled it out of the pump. I really don't know, but the clip came bouncing out when I pulled it apart.

The attached pictures show the correct way for anyone in the future that pulls a SB Ford apart. The long end with the clip attached goes up. The clip bottoms against the block and prevents the shaft from (normally) pulling out of the pump when you remove the distributor.

As a note, this ARP pump drive is similar to the Ford heavy duty version, but does appear to be finished a bit nicer. Also, the ARP pump to block and pickup to pump bolts are their normal high strength rather then the Ford's which have 4 lines on the head, denoting some sort of spec that I'm not familiar with yet.
