APRON DRIVE SHAFT
Grease three bearings on the side drive shaft, one
pump every 8 hours. Figure 10.
Grease bearing at both ends of the top beater,
one pump every 8 hours. Figure 7 and Figure 11.
Grease the bearing on the left end of the lower
beater, one pump every 8 hours. Figure 11.
Grease the bearings on both ends and the center
of the rear apron drive shaft, five pumps every 8 hours.
Figure 8.
There is a bearing at each end of the shaft
connecting the PTO shaft with the front roller chain
drive. Grease these bearing one pump, every 8 hours.
Figure 10.
Lubricate the PTO universal joints with 1 pump of
grease every 8 hrs. Lubricate the telescoping members
of the drive shaft with 4-8 pumps every 8 hrs. Figure
10.
Grease the beater clutch, two pumps every 8
hours. NOTE: This clutch is used only for “over run”
when the PTO is stopped, preventing damage to the
tractor. Figure 7.
SHEAR PIN HUB MAINTENANCE
The spreader drive train is protected with a shear
pin hub at the front end of the side drive shaft. If the
shear bolts shear, determine cause of overload and
correct. Figure 9.
1. Realign holes in sprocket and shear pin hub and
replace bolts. Snug lock nuts only enough to
remove all slack. Do Not Tighten completely.
2. Use 3/8x1-1/4" Grade 2 bolts and 3/8" lock nuts
only. Spare shear bolts are stored in a bracket
adjacent to the shear sprocket.
