I spent this evening searching on Google for Vacuum Pump rebuild Threads, for the Piston and the older Diaphragm type pumps.
Read threads from Peachparts, Benzworld, MBCA , a couple You tube Videos from MB Sauce, and one Forced Induction did.

There has been threads in the past of bypassing the engine driven Pumps because of the bearing possibly falling into the Timing chain and putting an end to the forward motion of the vehicle.

Electric Pumps have been discussed, not sure where that has gone.

I came across this one used on a Citroen and Peugeot.

Add a pulley to it and a way to mount it to be run off one of the belts might solve the problems with the bearings falling into the engine.

Whadayathnk?
