Well, it's not just lubricating the moving parts, it's polishing up the corrosion on the commutator on the motor that moves the parts. It's almost always sitting in the same-ish position, so you need to either polish up those spots, and/or move the rotor to brush alignment so a different part of the commutator is being used. > When mine (in a 900/-91) was dying, I finally ordered a second-hand > AIC valve from a junkyard that collects wrecked Saabs.

It's not worth too much work, but if you're comfortable with, say, a brake rebuild, an AIC valve isn't bad. Dave Hinz
