Post subject:  Oil Pump Gear Failures, What Cam Were You Using?

So far, the majority of the gear failures I've heard about happened to be with the 528 Mopar cam. Anyone lose one with any other cam? :?:

If it is cam related, maybe there's a batch of cores with a out of spec gear. Most cam companies don't hobb the gear on the cam themselves so they must be relying on a core supplier, is it Mopar? Where ever the cams came from that were involed in gear failures, are there cam core marking or casting codes that can ID a specific batch?

Our failure was indeed the 528 cam (at 500 miles) But the cam that I put back in was an identical 528 purchased at the same time and place as the first one. The difference? The Hardened gear ! We now have 5500 miles on with no problems.
