'88 K2500(6lug) 6.2 Diesel TH700R4 4x4
This truck was bought used and wasn't maintained all that well. If the
truck sits for at least an evening with the temps 20 degrees or lower, the
starter doesn't seem to engage for a while. each time it just sounds like it
spins free. With the hood open, you can see the fan move ever so slightly
each time the key is turned to start. After a while, it will turn the engine
over a half revolution or so then spin free.
We pulled it out, floor tested it and it jittered when floor tested. The
drive came out and seemed to hit normally. I proceeded to disassemble it.
After new brushes, new solenoid, a thorough cleaning, testing everything
electrical in it for shorts, it was reinstalled.
Free spinning for a few key turns, then engaged every time!
I have never done it, or heard of it for that matter, but I was told that
the solenoid piston should be lubed with dielectric grease to help keep it
from sticking. Is this common practice?
I was thinking that the one-way clutch in the drive might be bad.
Any help on this?
