Assembly Procedures (continued...):

34. Re-install support roller shafts continued:

iii) Install support roller shafts (PN 101-3939) in four locations where they are coincidental with the top and bottom brake band

lug weldments (top left & bottom right weldment PN = 101-0083, top right & bottom left weldment PN = 101-0096) as shown in

illustration 3.H.6. These support rollers do not use top or bottom washers.

35. Thread the top shifter bushing (PN 101-0020) into the top plate, over the shifter shaft, until snug. Thread the detent tube (PN 101-

0019) into the top shifter bushing as shown in illustration 3.H.7. Thread three 5/8” NC x 5/8” hex socket set screws into the remain-

ing three ports in the bushing - these set screws are intended to be used as contamination barriers only. Do not bottom out the set

screws on the shifting shaft, or the shaft will not move.
