Auxiliary air pump repair
My aux air pump sounds like a tiny buzz-saw for about a minute after cold startup and my understanding is its the bearings. I found instructions for repair on Rennlist for a 911 pump, which entails opening up the pump and greasing the bearings, but my pump seems to be different from the 911 pump.
Has anyone repaired the aux pump and if so, how do I do it?
