Anyone else notice that the shop manuals don't give specs on the transmission shaft dimensions?
 
a member on the NOC site noticed that too:

"The workship manual gives spec.s for the i.d.s of the various bushes and of the rolling element bearings but not for the corresponding diameters on the shafts..."



In 2008, a member started a thread asking for tolerances of the layshaft and mainshaft he had measured, with two images of the shafts with the dimensions of the location where each gear rotated;
for the mainshaft, "You will notice that two areas that are free from wear (as no bushing/gear runs on these areas) are the original diameter at 0.8100."
and asked, "What is the 'as new' diameter?"

Gearbox shaft wear - mainshaft and layshaft​
