Procedure
Important: The drive shaft yokes must be exactly in
line with each other when the outer yoke is installed on
the gear box splined PTO shaft. Remove the sleeve and
change the yoke position if the alignment is not correct.
Misalignment of the two yokes will shorten the life of
the drive shaft and cause unnecessary vibration when
the cutting unit is operated.
1. Line up the holes in the yoke and input shaft of the
gear box. Slide the yoke onto the shaft and secure them
together with a roll pin and 2 capscrews (5/16 x 1-3/4
inches) and locknuts (5/16 inch) (Figure 11).
