Belt Service; Clutch Cable Adjustment - Snapper I422 Manual

Section III - MAINTENANCE
BELT SERVICE
Belts do not require attention at any specific
interval, but should be checked if performance
deteriorates. This could occur due to slippage of
worn or loose belts. Check and adjust tension of
clutch cables first as described in the CLUTCH
CABLE ADJUSTMENT section. If performance con¬
tinues to be poor, after clutch cable tension has
been corrected, then check belts. MAKE SURE
ENGINE IS STOPPED AND SPARK PLUG WIRE
DISCONNECTED before working on the belts.
CLUTCH CABLE ADJUSTMENT
If slippage is noted, check tension of both clutch
cables. When properly adjusted,the cables should
becorhpletely slack with clutch handle released and
tight when the handle is fully depressed. The
springs on both cables should deflect 3/8" when
the handle is depressed. To adjust, loosen nut on
cable connector, turn connector to shorten or
lengthen cable as needed to attain the 3/8" deflec¬
tion, turn nut tight against connector tube to lock at
correct setting. Refer to FIG. 3.5 and 3.6.
NOTE; Blower rotation should cease within five
seconds after clutch handle is released. If rotation
continues after five seconds,cable may be too tight.
If readjusting the cable does not correct the
stopping time, check to make sure the idler return
spring is connected and that the idler is properly
set. See your SNAPPER Dealer to have this
condition corrected.
BELT TENSION: Tension on the traction drive belt
is automatically maintained by an individual idler
spring. After removing the belt guard and bottom
cover, check to make sure this spring is intact and
properly installed. If the spring is properly
connected, check for excessively worn belts. Notice
the return spring on the idler for the Auger/Impeller
drive-this spring activates the brake. The idler
should always return to braking position! Tension of
the Auger/Impeller drive belt, which is on the 3/4 dia.
engine drive shaft, is adjusted by loosening and
repositioning the idler puley. To increase tension,
loosen the idler pulley retaining nut, hold the idler
arm and push the pulley tighter against the belt. See
Figure 3.4. RetIghten nut after repositioning and
check for proper clutching action with blower clutch
handle released. Tension of the traction belt on the
inside pulley is non-adjustable. Before reinstalling
belt guard, check to make sure the belt guide on each
side of the pulley is about 1/16" away from the out¬
side surface of the blower belt with clutch engaged.
Adjust the guide by loosening bolts and moving
guide.
