Hello all. I am new to this site. I currently have two project trucks. One is a 47 one ton, all original. It was my grandfathers truck and all the parts are there. I also have a 52, 1. 5 ton truck. This truck has a later 235 in it with oiled bearings. The other has the babbit engine. The 1.5 ton truck has a three speed auxiliary Watson gear box in it. Over and under drive. There is also a PTO on this truck. My question is does anyone have manuals they can share on rebuilding a Watson? I have a Model 42. I have some info, IE gear ratios, shift pattern and a few cutaway drawings that I have found on the net. If you have any thing you wish to share I would be most grateful. Thanks in advance!
