Vacuum Pump

[MIDNIGHT RIDER]

all three bolts are captive to the pump with the pulley installed.

Please explain "captive", thanks.

the v-belt pumps have the threaded bolt holes. the serp pump has open holes in the castings for the bolts to go through and mount in the alu bracket.

That is good to know and something I will have to keep in mind when collecting these pumps at swap-meets and the like.

As many as I have accumulated, I have yet to see one that didn't have the threaded holes.

Captive...you can't get them off with the pulley on.

On mine at least You can loosen the bolts that hold the V pump to the engine but while the pulley is on the pump You can't take the bolts from the pump just loosen each one a few threads at a time until it is out.
