I'm working on a 1934 BS gas road roller but can't figure out how to remove the clutches.  The final drive has two clutches, one on each side of the gear box.  I can't seem to get the outside gear off and afraid I'll destroy something if I put too much pull on the gear.  Does anyone have any idea where I could look for a diagram of the transmission and final drive?  There must be a parts book somewhere but I don't know where to look.
