Howdy All, ran into a problem today, I recently rebuilt my Ross TA 12, new bushings, and turned my pins 90 degrees. I have been waiting for steering box grease and seal from SI to put it all back together. Today the grease and seal arrived, and when I went to insert the shaft though the new bushings it is a no go! They are so tight that even bumping the shaft with a rubber mallet produces no movement through the bushing.:( I tried the shaft on both bushings with the same result. There were no burrs, or other blems in the openings when I pressed them in. I double checked my invoice from SI, and my parts book numbers, both are #680210, so they should be the correct ones for my TA12. I mic'd the shaft and the bushing opening, and they are .937, and .934, so there is a difference of about .003 Shy of having the wrong bushings am I missing something here? Thanks for any suggestions.

You may have to have a machine shop ream the bushings to fit such as is done with king pins.Not unusual to have to have that done.

.003 could be a tight press fit. Is it possible to use a C clamp and a deep socket to press the seal in? Or, as the manual for my '53 says, a block of wood and a lead hammer.

Thanks for the input 41 Frank, I kinda figured that they might have to be reamed, just one of those jobs that you would rather put off if possible! ;) Chucked the shaft in the lathe and dial indicated it, and it was about another .002 out of round. After some carefull measuring, I reamed those bushings this morning, and now have a pretty good fit. Snug at one side when the shaft is turned, but they should wear in OK. Thanks Again
