Thanks and Information
I would like to begin this post by thanking all the forum members who have shared their knowledge over the years. Having no training as a mechanic, I could not have accomplished what I have on my Model A without the help of this forum.
That said, I am asking for the members to share their knowledge about cam shaft bearings and axle bearings. None of the restoration or maintenance manuals that I have mention these bearings. All of the books seem to treat these bearings like they don't need replacement, and that the shafts are just shoved into place. Likewise, these bearings do not appear in the parts catalogs of the suppliers that I know of. Lastly, I have had little success searching this site or other Model A forums for information. Please excuse me if this topic has been covered; perhaps someone would direct me to the discussions. Thanks, again. Mike |

I'm sure Ford never expected the Model A to last 90+ years tho.

I imagine that if a block has excessive worn camshaft bearings (holes) that the block could be reamed and bushings inserted. I don't have the specifications, but the rollers on the axle bearings can be measured with a micrometer. If they are 0.002 undersized then they need replacing. Or if pitted. Model T rollers, if I remember correctly, are 0.500 originally. Also they need replacement if the pins that hold them together are loose and cannot be peened to tighten them. I am not sure if a Model A has a sleeve but if that is oversize or pitted it needs to be replaced. The shaft journal also needs to be measured and replaced if undersize. Again, not sure of the specifications but in general you are looking for excessive wear. Perhaps someone with more knowledge can chime in.
