2-8 Adjusting The Dump Mechanism
The linkage rods may be adjusted in two places, at the
adjusting screw P#(K1435 and the latch assembly items.
See Figures 9 & 11 for visual clarification. To change the
door closure tightness, screw the adjusting screw in or
out. To adjust the latch, change the length of the latch
rod by screwing the latch adjusting ball joint in or out.
The latch hook pivot should be in the middle of the slot in
the latch hook pivot plate. Slide the pivot back or forth
and then re-tighten.
2-9 Belt Installation
Loosen the (2) bolts that secure the gear box assembly
P#(A0429) to the PTO mount plate (Figure 14). Loosen
the adjustment bolt P#(K0348) until the gear box
assembly is at its far left adjustment (the gear box is
moved towards the mower’s engine pulley). Connect the
kevlar cord belt from the engine pulley to the lower gear
box pulley (Figure 15).
To tension the drive belt, turn the adjustment bolt
clockwise until there is 1” of deflection, with 10-11 lbs. of
pressure between the engine pulley and the gear box
pulley.
Once the correct tension of the belt is achieved, tighten
the (2) bolts that secure the gear box assembly.
2-10 Cam Assembly Adjustment
The cam assembly P#(A0422), which controls the
blower belt tension, comes from the factory pre-adjusted
if the belt is too tight or becomes too loose, remove the
hair pin clip P#(K0099) from the belt tension rod
P#(K0326) and pull the “L” end of the rod out of its hole
in the cam assembly. The tension rod may then be
screwed out to tighten the belt or screwed in to loosen
the belt. Replace the “L” end into the top hole in the cam
and replace the hair pin clip. Adjust the cam stop bolt
P#(K1159) to allow the cam to rotate slightly over center
when the blower is disengaged (Figure 16).
