vacuum pump pulley. should it turn freely?

Hey guys,

quick question about the vaccum pump pully on my '96 OBS. I went to replace the serpentine belt this afternoon and was checking all the pulley to make sure they turned freely. The A/C, idler, etc all spin freely but the vacuum pump one does not turn at all. Is that how it should be? Should it resist a hand turn?

Thanks for the help.

It should hand turn, with some resistance. You'll feel the resistance go up and down as you turn it, and the diaphragm does its thing. But it sure shouldn't be so tight that you can't turn it by hand.

+1. You need a new vacuum pump.

Trust me. Replace the vacuum pump and get the one that comes with a new pulley. My vacuum pump just put me and my 5th wheel on the side of I-40 in New Mexico. It threw the bearings out of the pulley and shredded my belt. It took 2 wreckers to get me off the hi way. One towed me 60 miles to the only Autozone that had the pump with pulley. Trust me after that experience spend the extra coin and save yourself 5 hours on the side of the road.

My vacuum pump does not have a bearing on the pulley it is in the pump itself. You must have a diff. setup.

bearings are in the pump. When they go, you're done...replace it if its that hard to turn.

None of them have bearings in the pulley, by definition. The pulley has to turn the shaft.

The replacement pump that comes with the pulley must be the Cardone 64-1029, and it has (as it would have to) the bolts already in the bolt holes, captured behind the pulley. That's a reman pump, and Cardone's reputation for quality is right "up" (ahem) there with Dorman's. There are a couple of online sellers, accuratediesel.com being one of them, that carry new (not reman) pumps. All you need is a power steering pulley tool, which is cheap at Harbor Freight, or can be borrowed for a deposit from your FLAPS. Depends on how quickly you need to be back on the road.

AZ has a _new_ Cardone pump, without the pulley, for less than the reman one with the pulley.

Thanks for all the replies. Y'all were right. Fired up the truck this AM to go buy a new vacuum pump and the pump blew and shredded the belt on the way to the store. At least it happened in town and not on the road. That pump only lasted me 30 months, just barely out of warranty. Lesson learned.

Thanks for the help.

You could've prevented shredding that new belt if you'd heeded the advice before starting the truck. Or did you put the old belt back on for this trip?

The creepy ad-bot strikes again; banner ad indicates the Cardone 64-1029 for $89 on amazon. Amazon has had some good prices on auto parts lately, usu. with free shipping. Now if only they could get that 30-minute drone delivery thing figured out.....
