Bronze Oil Pump Drive Gears - Only $128.16

Bronze Oil Pump Drive Gears for Harley Davidson Sportster and Buell Models

Sportster and Buell engines are notorious for wearing the oil pump drive gear on the pinion shaft. Pinion shaft runout causes this. HAMMER PERFORMANCE has the solution, though, a bronze oil pump drive gear that greatly reduces wear in this critical area. Check your stock drive gear; if the teeth are getting sharp on one side, it's time to get one of these. If you're into the cam box anyway for a cam change, it's cheap insurance.

Note: a pinion gear locking tool is absolutely required to safely change this gear, i.e. without the risk of scissoring your crank.

Pinion Gear Locking Tools

GrindLock Pinion Gear Locking Tool for Harley Davidson Sportster and Buell Models

OK, so it's not directly related to lubrication, but if you're changing the oil pump drive gear as described above, you need this tool! If you hold the crank still from the other side of the assembly - the primary side, or by putting the bike in gear and holding the brake - you apply twisting force through the crank pin, and the crank pin is not designed to resist much twisting force. You run the very real risk of knocking the crank out of true, which requires a full tear-down to fix.

Don't take the risk, get yourself one of our exclusive Grindlock pinion locking tools. We work on these bikes all the time, and frankly the other offerings on the market for this function frustrated us with weak teeth that liked to push away from the pinion gear. The Grindlock design solves that problem. It also engages for the full depth of the pinion gear for maximum strength.
