Trying to locate steering prts
« on: February 27, 2015, 04:22:01 PM »
We have taken the ZF Ross steering box apart. What we found is that the pin was not moving and the double tapered bearing has worn. In addition one of the bearing races for the worn gear is badly worn. I am trying to find the small tapered roller bearings and any other parts that could be available. The bearings are individual.

I found two auctions on ebay but I need the part numbers to match what they have listed. If anyone has the part numbers for the components, that could also work.
Thanks
Chris

These boxes were licensed from Ross which I think was an American company, now part of TRW. The parts book calls out inch dimension bolts (but the 5/16 x 22 is a BSF thread pitch). The balls are 5/16". It's possible that some of these parts interchange with other old Ross boxes, but I haven't done the research.

Maybe if you send me or post some dimensions of the follower pin, I can compare it with the 170 boxes, but as I said in my email, it's probably larger. The sector shaft looks nasty, you will probably have to have that ground on a centerless grinder.

I've looked at this website of a place in Argentina. I believe it was posted here some time ago.. http://www.chsauto.com/en/ It might be worth sending them some pictures and see what they have.
