Hello all:

I want to share some information about rebuilding Saginaw power steering pumps. My '89 760GLE was leaking fluid all over my driveway at an increasing rate, and would lose significant quantities of fluid on longer trips. This last weekend I finally worked up the courage to tackle it.

I called around for replacement parts, and was quoted a staggering $285 + tax (CDN) for a rebuilt pump/reservoir combo-- that didn't include the $75 core charge! Another shop offered just the rebuilt pump for $119. I called Canadian Tire and asked about a pump rebuild kit, and they had one for $16.32! The kit was fairly complete-- 7 o-rings and a new oil seal for the shaft, with reasonably comprehensible instructions.

After 150K mi, most of the seals were well worn and very brittle. It took me all of an afternoon to dismantle, clean and reassemble the pump. Putting the reservoir back over the pump without displacing o-rings was a bit fiddly, but not too bad. At several points it was very helpful to have a second set of hands.

Total cost, including replacing the fluid, the return hose, some hardware bits and all clamps was under $25. It seems to work great so far, and no more spots on the driveway!

Now I need to find someone with a lift so I can tackle the rear main on my B280F...
