Got home a little early tonight, and decided to tackle the transmission on my 1939 9N. I already had that section seperated and on the floor, so all I had to do was dissassemble it and pull the gears out. This tranny was very noisy when I drove it for the test drive before buying, so I expected the bearings to be shot. Surprisingly, the bearings were in great shape and almost like new, even more surprisingly, they had the Ford script on them and the part number (and Timken stamp as well). Not sure if they are the originals, but very old none the less to be in such good shape. The main shaft came out - and so did the rear bearing! It just slipped right off the shaft, so I tested the front pilot bearing, same thing. Now I am assuming they should be fairly tight on the shaft, so I will need to address that. All the cups have slight pitting, so I will replace those. The gears were in grear shape except the far rear gear on the bottom shaft, there were some teeth that were chipped pretty bad - but only in one area. The bearings on the bottom shaft are in good shape and tight on the shaft.Still baffled at why the tranny was so loud, I turned over the main shaft (which looked to be in excellent shape) and there it was. It didn't look like pitting, it looked like gouges all around the circumference Like the bearing was wobbling around inside there. Now, seeing as this is a '39 with a straight cut gear on the end, finding a new one will be daunting to say the least. Any ideas on how to maybe fill these gouges and smooth down flush with the rest of the surface? Also, any ideas on what to do about the bearings that are loose on the main shaft? Loctite? TIA,
Dan
