Which can case even the Newer type Vacuum Pumps with the Bearings that have a Metal Cage and Washers that shield them from falling out.

My question What in particular causes vacuum pump failure?

The pump piston was broken where the connecting-rod is bolted to it. Since it happened at the same time that my pump bearings came apart, I'll assume that caused the excessive play, since the new pump has been working reliably in there about 5 years now.

Happy Motoring, Mark
