Carriers off. Now I understand what I am working with. First glance the grease fittings are 180 degree off from where the load is. The carrier has a proud grease groove and the journals have a recessed. On the carrier that proud surface is worn off bottom 1/3 and toward the front. Makes sense driving forward and machine load. Fittings appear to fit in that wear location on bottom not sure why that wouldnít be the spot.

Bearings and seals/races are good shape but going to replace. Diff fluid might have been over filled and slightly milky. Will be adding magnetic drain plug on the diff.

This is the type of wear we are working with .

You can see the proud grooves on the top.

So plan is:

1. Hope some of these journals exist . At 1 or two more while adding bearing material to the worn area.
2. Have them made and add 1 or two more with bearing material worn area.
3. Just add bearing material and run it.

We shall see.

The piece in the pic is the outer carrier and axle bearing carrier. Due to the low wear it is a good representation of what he original journal would have been.

It is reversed on the picture .

Any idea what this repair modification was for? Brace on stop and flat stock on bottom.

I was told a story of this cat losing a rear track and driving 13 miles down the mountain before operator noticed.

Canít see how this fixed it unless some was in low or no snow condition and the track bent the stop when it came off and rocks destroyed the bottom?

Real poor stick welds. Doesnít make sense.

Here are what my factory stops looked like.





Cut out the bent section and inserted thick wall square tube but donít think it would be enough.

Got few things removed on the cat and a little final bench mock up.

Donít think rubber hose is a good bushing material. Springs need to be bushed and tuned up a little.

Table bolt holes need new bushings so going to take the whole thing to the machine shop tighten it all up like new.

Great timing today. Dropped the springs off at my fleet shop to catch the next ride to the spring shop. One of my trucks happened to be sitting there with a broken shackle and they were headed up to the spring shop today.

Two for one Friday!

Tie rod and rear tables off. Someone already rebushed the center pivot bushing in the table and they must have redone the tube bushing also nice and tight.

Tie rod ends nice and tight. Just need to address the spring bolt holes which should be easy.

Little paint and reassembly.

We are trying automotive paint for this project. We buffed a section of good paint on the table and then color matched it. Mixed up some spray cans.

This is the recipe for the future. Put some on the table and when it dried matched well. Donít plan on painting the whole cat but want to freshen these parts I have off.

Took the differential out. No surprises. Will be adding a 1/8 npt drain plug.

The housing will now be much easier and lighter for me to dry fit the carriers and make the bearing tape repair.

Drain plug tapped. Going to go with something more low profile for final install.

This is the bearing tape repair. Those are not grease grooves in the carrier that is from the journal wearing into the carrier around the groove.

Nice and tight now. If the factory says it works then IN TUCKER WE TRUST.

Tapered wear also so had to do some layering but itís tight.

Those pontoons look familiar ????

Cross thread contamination. Wish the last guy finished these!
