Scavenge gear—driving

Driving scavenge gear for the oil pump, from the crankcase section of the parts book.

PN · 71-2122

This is the driving scavenge gear for the oil pump, listed in the crankcase section of the parts book. It's the gear that gets driven off the engine to turn the scavenge side of the oil pump, pulling oil back out of the crankcase and returning it to the tank so the sump doesn't fill up with oil the engine should be running on.

The catalog shows this part under 71-2122, with E12122 as the alternate form of the same number. Our record on this one only shows a single catalog appearance tied to 1971, so we don't have a broader fitment range to point to beyond that.

If you're chasing an oil pump issue, gears in the pump train like this one are worth a look for wear, especially if you're seeing oil retention or scavenge problems. Give the shop a call to confirm this is the right one for your engine before you order.
