Section 4 - REPAIR & ADJUSTMENTS
WARNING
Before attempting any adjustments, maintenance,
service, or repairs, stop engine and auger/impeller,
always remove key from ignition switch, remove
spark plug wire and secure wire away from spark
plug.
4.1 AUGER/IMPELLER and WHEEL DRIVE BELT
ADJUSTMENT/REPLACEMENT
When operating machine release the auger/impeller
clutch control, auger/impeller should come to a
complete stop in 5 seconds. If auger/impeller does not
come to a complete stop in the required time, check
and adjust belt tension. Inspect belt frequently for signs
of excessive wear. Observe drive belt for slippage due
to wear when operating machine. If slippage does
occur, adjust as follows.
4.1.1. AUGER and DRIVE BELT ADJUSTMENT
(CABLE ADJUSTMENT)
1. Measure control cable extension from a relaxed
position to full extended position. Move control lever
against handle. Measure from the top of spring (The
top is in relation to where spring connects into
connector). The cable spring should stretch 3/8”
when the auger 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 rotate cable beyond the point to
where all of the slack is out of cable. Cables have to
have a certain amount of slack: When control lever is in
the released position the cable slack allows: 1) Auger
brake to stop auger/impeller. 2) Wheel drive to
disengage. If all of the adjustment is utilized at the cable
connector go to Section 4.1.2. for alternate adjustment.
4.1.2. AUGER BELT ADJUSTMENT
(IDLER PULLEY ADJUSTMENT)
NOTE: Wheel drive belt idler pulley is not adjustable. If
upper cable adjustment performed in Section 4.1.1.
and correct cable extension can not be accomplished,
adjustment can be made at the idler pulley. All
adjustment made in Section 4.1.1. will have to be
reversed from the upper end of cable.
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.
