does tdr have a carrier bearing puller d70

[GMichaels]

Was wondering if the tdr has a carrier bearing puller for the dana 70 that gets passed around as needed? they cost about 350. 00 hard to justify the cost.

Check with your local parts places, most loan or rent tools like that. You need a bearing splitter and a two legged puller. bg

puller

You need a specific puller for the dana axles. no room to get behind the bearing.

Like BG said, use the bearing splitter, it is a two piece clamp with a sharp edge that will clamp between the bearing and case. Then you pull on the clamp with a regular two jaw puller. The Dana axles of all sizes are a bear to work on with out the special tools. I have built lots of them without the tools, but be prepared to spend lots of time and it will try your patience to the limit. Keep track of all the shim packs and know where they came from, then use new ones of the same amount and start from there. If the carrier, housing and ratio didn't change, you will be close.

Some used the old bearing set(s) and open up the race to slide on/off. Thing is... . you gots to be able to git 'em off in good shape.



I like to to cut the bearings/weld the bearings to remove and purchase a duplicate set to set up the gears and then install the new (unmolested) set for the final assembly.



It works well.

bearing puller

Ya, bearing puller will not work in this application, got one, tried that, no dice.

I honed one set of bearings out with a cylinder hone for setup bearings. Destroyed the rocks but they are not too high.



You can remove the old bearings by removing the rollers and heating the race with the blue wrench. Some will fall off and others need tapping with a hammer and drift punch.

Read the thread

that Greenleaf posted on the 3. 07 Dana. It is on the second page now. I posted the following there.



To my knowlege, no such thing is available. It would be expensive to ship around and I don't know who would spring for the initial outlay. What I have been trying to figure out is how one might make a simple puller that would work which was not so expensive to build, then, anyone who wanted to do their Dana work could be assured of getting it right. Any input from the creative cobblers on TDR????

I built one, worked ok but got bent the second time i pulled the bearings. I would copy the design of the professional tool, which i may try soon, 350. 00 is a lot to spend.

tools

I can make the spreader tool. Have done this once before but did not have enough preload. My homemade side carrier bearing removal tool bent. The cost of taking it somewhere is much more than the tool, so I would just by the tool and at the end I would have the tool.



I am just cheap and don't want to spend the 350. 00



Now about the air chisel, you won't damage the shaft?

Puller

Has any one had their hands on the carrier bearing puller that thinks they can describe some of the functionality of the unit? Specificly, does the shoulder/ collar load against the cage or the rollers?



I am discussing with another machinist , who has a CNC lathe, as to making some parts for a puller. My thoughts are to use a large pipe coupling as the outer body and have two half pieces that will screw into the coupling and something for the other end of the coupling that will have the forcing screw in it. I want to know how to shape the grip collar/shoulder that fits behind the bearing.

Pictures

I had looked at pictures last year but I didn't have near as good clarity as these shots. From what I see, the puller flange must load against the cage.



Thanks Alan

The cage won't cut it. The two puller halves have to have inner diameter same as the bearing cups that fit the carrier bearings. The halves will also have a lip that catches over the top (larger diameter end) of the bearing rollers. If you could make the halves extend beyond the small end of the bearing far enough to have a jacking plate fit into that end with a lip to hold it in place and a collar to fit over the two halves strong enough to handle the load, might work?? bg
