My Pete rebuild

[pearce trucking]

Yes. I had to replace mine, and I took it apart and looked at it before I returned it for the core.
Its a fairly simple mechanism. There's a circuit board with a gear that is driven by it. Then two gears that the aforementioned gear drives, and they in turn drive the one that sticks out the bottom. All the grease was dried up on mine, and the bearings were pretty well seized. You shouldn't ruin anything by disassembling it carefully. You may get lucky and be able to loosen up the works. But I imagine that they're getting to the end of their useful life. Have you had any codes or boost issues with it before?
