4.1 AUGER/IMPELLER and WHEEL DRIVE BELT
ADJUSTMENT/REPLACEMENT
When operating machine release the auger/impeller
clutch control. The auger/impeller should come to a
complete stop in 5 seconds. If the auger/impeller does
not come to a complete stop in the required time,
check and adjust belt tension. Inspect belts frequently
for signs of excessive wear. Observe drive belts for
slippage due to wear when operating machine. If
slippage does occur, adjust/replace as follows.
4.1.1. AUGER and WHEEL DRIVE CABLE
ADJUSTMENT
1. Measure control cable extension from a relaxed
position to full extended position. Move control lever
against handle. Measure the overall length of the
spring. The length of the cable spring should
increase by 3/8” when the clutch control lever is
depressed. See Figure 4.1.
FIGURE 4.1
2. Adjust control cable by loosening jam nut at the
upper end of cable. Hold threaded end of cable and
then turn cable clockwise or counter clockwise until
correct extension is achieved. Retighten jam nut.
IMPORTANT: DO NOT over tighten the control cables.
The cables must have slack for the auger/impeller brake
to function properly and for the wheel drive to de-clutch
properly. If the auger control cannot be properly
adjusted, belt adjustment and/or replacement will be
required. Refer to Section “Auger Belt Idler Pulley
Adjustment”. If the wheel drive control cannot be properly
adjusted, the rubber drive tire will require replacement.
Refer to Section “Rubber Drive Tire Replacement”.
4.1.2. AUGER BELT IDLER PULLEY
ADJUSTMENT
NOTE: To adjust the idler pulley and properly tension
the auger belt, the auger control cable adjustment
must first be loosened as described in the following
step. Cable adjustment must be checked after
completing the idler pulley adjustment.
1. Loosen jam nut at the end of cable. Hold
threaded end of cable and then turn metal housing
of cable counter clockwise until threaded portion of
cable is extracted from metal housing. Reinstall 1/2”
of the threaded portion of cable back into metal
housing. Retighten jam nut.
2. Remove belt cover. See Figure 4.2.
FIGURE 4.2
3. Loosen nut and bolt that secures the idler pulley.
Move idler toward belt for more tension or away
from belt for less tension. See Figure 4.3. Retighten
bolt and nut securely.
