D-2 Roller bushings

I am in a similar boat with my 5J. I plan on boring the old ones out then press fitting a new commercially available sleeve in. This assumes they are not totally worn through or too thin.

Since the original bushings are closed on one end, I figure it would be prohibitively expensive to make whole new ones out of solid stock. If you find a source for new ones, please let us know!

In a pinch, I suppose you could just flip them 180 in the housing so the unworn area takes the load. Not good on the seals though with the shaft bouncing around on uneven ground.

Off Road shows 3 at $62.00. Just went down this path but was lucky had some spares. Next time I would dig out my furnace cast some cores and machine to size. Most areas have someone that does casting - just round up some brass scrap. Bob

Thanks for the different ideas. I pressed one out ,not hard to get out. I don't think its good enough to turn and reuse . I like the idea of having some castings made ,local scrap yard has brass scrap but don't know where to get them cast yet.The seals are damaged but I think I can make some that will work. Will check with Florin about some new bushings, didn't think any were still available. Thanks again for the different ideas.

Hey,

I am about to do the same on mine, bushes are slogged out and need to be removed so I can turn some new ones up.

Question: how did you press them out? having a look at mine you can't get to the back of them as its sealed by the casing ? I was considering drilling them out.

also does anyone know the original measurements for the bushes & the pins they run on ? I can easily get the O.D from the housing for the bushes but my pins are worn so getting the correct pin measurements is hard, I would like to build them back up to original specs.

Cheers.

The track rollers on my D 2 seem to be the same style as the 22 which uses a bushing the same OD clear through the part that bolts to the track frame . later D2 roller bushings are different. The early style push out easely with 20 ton press. Got bushings from Mc Master Carr 1 1/2 ID x2"OD ,cut off solid end of old bushing with grease fitting and pressed back in ,locked in with set screws. also had to ream the inside of bushing for roller shaft and wrap 0.025 steel shim around bushing before pressing into holder.

okay yeah must be different as I have no way of getting a press into the back of the bushes on my 5U - my manual has a photo of a big puller being used to get them out so I might need to look into this option, does not appear to be heaps of room inside to get the pullers claws into but it might be just enough.

My apply some heat to see if that helps.

I used a 3 fingered slide hammer puller but had to grind the finger tips to get behind the bushings as they are close to the back wall of the housing. The bushings were very tough to get out and I had to really pound on slide pretty hard. I found bushings from Bronzebushings.com in Detroit Mi. USA for $20 each. The closest size were the right length and ID but were 2mm ,too large OD so I had to turn them down a bit.
All the bellows seals were completely destroyed so I made round aluminum plates that fit into the housings with an inside hole just slightly larger than than the shafts then machined a groove inside and fit an o-ring. I secured them with 4 counter sunk screws I fitted into the seal spring holes after drilling and tapping them. I used the thrust plates and shims to take up space and control the end play. I hope with a lot of grease the seal plates will last a long time and found an Alemite volume grease can to keep them pumped up.
