WARNING: DISCONNECT PTO DRIVE SHAFT AND HYDRAULIC HOSES (RELIEVE HYDRAULIC
PRESSURE) BEFORE CLEANING, ADJUSTING, LUBRICATING OR SERVICING THIS SPREADER. FAILURE
TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
FRONT DRIVE ROLLER CHAINS
There are five roller chain drives located at the front of the spreader. Regularly check that all tensioning springs are
in serviceable condition for automatic roller chain tightening. Manually adjust spring tensioners (as needed) by
turning double locknuts on all tensioning bolt/idler assemblies. Proper roller chain tension is when 1/4” to 1/2”
deflection occurs on the slack side of the chain. Regularly re-check all roller chain tensions. Keep all roller chains
tight at all times! For clarity purposes, the following illustrations detail each roller chain reduction separately.
NOTE: The side bars of the roller chains will wear into the idler nylon rollers up to the rollers of the roller
chain forming grooves. These grooves will serve as a guide when the roller chain loosens due to
normal use. From this point on, after tightening, the idler nylon rollers should run for hundreds of
hours without any noticeable wear.
SPRING LOADED ADJUSTER
The primary chain drive (PTO input shaft to the large
RH top sprocket, Figure 10) is automatically tensioned
by a spring loaded idler nylon roller. The extension
spring should extend 2” from its neutral 5” total length.
Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the left rear of the
spreader’s front bearing mounting plate.
SPRING LOADED ADJUSTER
The transfer chain drive (large RH top sprocket to the
large LH top sprocket, figure 11) is automatically
tensioned by a spring loaded idler nylon roller. The
extension spring should extend 2” from its neutral 5"
total length.
Manual adjustment for the automatic tensioning idler,
nylon roller assembly is located at the front center of
the spreader’s front bearing mounting plate.
