I am redoing/checking a rear end of a 1924 Model T touring and a 1924 Model TT truck. I have read the Chaffin/MTFCA and Ford Service books and collected good old axle bearings for both(all bearing miced out well and surfaces in good shape). I did not find the acceptable thickness for the axle bearing sleeves in the Chaffin/MTFCA and Ford Service books. What is that acceptable thickness for a Model T and model TT axle sleeve?? I have several sleeves that look good and want to know if they are good on thickness.
Also what is the acceptable thickness for the Model TT worm gear bearing sleeve? I think I have NOS sleeves but the Chaffin/MTFCA and Ford Service books did not have this information either.
I never worried about how thick they are because all most all of them I have had are worn or flaking/pitted. If they are not worn or flaking/pitting I would use without worrying about how thick the metal is. There will be some up/down back/forth movement, these are not tight bearings like modern roller bearings.
The passenger car sleeves that Don Lang sells are made exactly from the Ford print, and the toughness is exact. Don't mess with anything else!
