Subject:      Power Steering Pumps - Again!
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Since I now have three Vanagons to maintian, and all three have bad pumps, I am facing a $900 bill for PS pump replacement, so needless to say, I have been studying the pump problem intently. Bentley has some really good illustrations of the construction of these pumps, and I see absolutely no reason one cannot rebuild them in one's own garage. The problem is the availability of parts.

These pumps are simple. A few gaskets and seals, a spring loaded pressure relief valve, a stator, a rotor, and some vanes to go in the rotor.

The parts that wear are the vanes - which wear against the stator, and the rotor, where the vanes wear in their respective slots on the rotor. Those three parts - stator, rotor, vanes - are really easy to replace. So, what is the deal with getting those parts. All of our regular list vendors carry the seal kit, ie, gaskets, o-rings, etc, but I have yet to see one carry the stator, rotor, and vanes. So why not? As common as these parts are on Vanagons, surely they are available somewhere to the public at large. Why would/should these parts be the exclusive purvue of automotive component/appliance re-builders.

I hope to turn this situation around, and I'm on the trail. Any input anyone has would be appreciated. I would like to add this as a success story to the archives.

Homey's have rebuilt/repaired AFM's, ECU's, Auto Trannies, PS racks, to name a few - all in their home garages. So why not PS pumps??

Thanks for any help.

Thanks for putting up with a semi-rant!

John
