I dont know anything really about differentials.
I got this for free, is it a power lock or true trac? if it's a true trac I'll be scrapping it but if it's a power lock I'll have it cleaned up and i'll put it in the highboy.
It's a 16 spline so it will swap in, but not about to pay to have a true trac cleaned up to put it in.
And the pictures truly make it look 100 times worse that it really is. It does need work, it has surface rust all over it. The buddy that gave it to me says he has a buddy that can make it like new for $75.
That's a powerlock. A tru-trac is better than a powerlock in some ways, but wasn't made until just a few years back. I bet you're thinking of a trac-lok. Those are scrap.
Before cleaning it up pull the ring gear side carrier bearing. If it's loose it may not be salvageable.
Cool deal, glad it's a powerlock. I dont know exactly what the side carrier bearing is but I'll start doing research on these things right now. I'll probably have it restored for that $75.
can't you adjust how much you want it to "lock" the wheels together with the power lock's?
guess i better start researching.
The carrier bearings, the large bearings that hold the carrier that are solid rust chunks in your picture.
When I see a carrier that looks like that the first thing I think is why was it pulled? There could be a thousand reasons why, but one I have seen more often then not is a spun carrier bearing. You can't easily tell until you pull the bearings off and find the ring gear bearing has badly damaged the carrier. You can peen the carrier and loctite the bearing, but I sure wouldn't put a dime into a damaged carrier. If the carrier bearing spins it spits the shims out. Without the shims you got no preload, no preload means everything goes to hell in no time.
Just saying check that first before making any plans to rebuild it.
There are two styles of powerlock clutches. The old friction lined ones and the newer steel ones. The way you stack clutches in the case determines how much holding power they have. I prefer my powerlocks with the newer steel clutches alternated through the entire stack on both sides, but the friction clutches work great too you just get real dirty oil and need to keep it changed regulalry.
