Hot Rods Who is the Dana Trac Lok expert

So I am working on a Dana with a Trac Lok and so far no success in reinstalling the clutches. Any tips ? There are four tools listed in a old Motor Manuel but I have not been able to find a photo of them. The tool numbers are J-8646-2 , J-23781-6 , J-23781-3 AND J-23781-7. I don't know what brand tools they used. The side gears have a Belleville spring that has to be compressed as you roll the spider gears in and that just ain't happening.

 

Chrysler used Miller tools.

 

I think maybe KentMoore(sp). I know many GM manual did refer to that company regarding “use KM # ….”

 

J lettered tools are usually Kent-Moore.

 

This is where I am at right now.

 

That’s the right idea. Only thing you are missing is a long bar that is the same size as the spider gear pin. Put the round bar in one spider pin hole and use that as leverage to rotate the diff around the spider gears. You will have to get your bolt set up just right tension so they will slip around there. Make sure there’s plenty of friction lube on the clutches.

 

It’s been a thousand or so years since I worked on one but I seem to remember rolling in the pinion gears with the bevel springs at the same time.

 

Yeah that sounds right, I came across this ****er manual and that is one of the tools they show ( a long handle ) I will get a fresh look at it today and see how it goes. https://media.****erparts.com/cfs/files/media/kF8WeN3yGdv9Pn52d/5314-2.p

 

Done, a fresh look and a longer lever and goes right together.

 

If memory serves, the clutches when new should hold to 65? I think rotational force.
I made an adapter that bolted to one hub, left the other tire on the ground. (Yes, set the brake/block the opposite side).
Torque wrench on the nut I welded to the adapter to verify.

 

I did not install new clutches, I am putting new bearings in and had everything apart for cleaning. The fix on Youtube is they drive the gears around with a br*** drift ( with all the chips of br*** now in the carrier ) as Ardinger said in a above post you need to rotate the carrier. So I clamped a axle in the vice to mount the carrier on, I used a 1/2 bolt , washers and a couple nuts to spread the side gears by compressing the Bellville springs. I was concerned about damaging the pin hole as I did not have anything that was a tight fit. So I used a piece of 1/2 threaded rod through a ring gear bolt hole as my leverage point. Then set the spider gears in place without the thrust washers and rotated the carrier until the spider gears lined up with the hole for the pin.
Installing the pin is straight forward for the most part, as you tighten the nuts pushing the side gears outward this allows the spider gears to drop towards the center line of the carrier making installing the thrust washers and the pin easy. Maybe down the road someone will find info. this and benefit from it. I wonder how many problems Youtube repair videos create. I guess I am now the expert !
