d) Tap the pulley/bushing assembly against the shaft
shoulder with the soft hammer.
e) Tighten the 1/4 inch diameter capscrews
progressively with a torque wrench to 95 inch pounds.
Note: this installation procedure is also used when
installing replacement pulleys.
8) Belt alignment is checked with the straightedge.
Place the straightedge squarely against the driveshaft
pulley. Properly aligned pulleys should also place the
straightedge squarely against the engine/electric
motor pulley. Remove the straightedge and rotate the
engine pulley 120 degrees. Recheck the alignment
with the straightedge. Repeat the process until the
engine/electric motor pulley has been rotated a full
360 degrees. Maximum allowable misalignment is +-
1/32 inch. FIGURE 36.
If engine crankshaft/electric motor pulley alignment
needs to be adjusted, proceed as follows:
a) Using the 7/16 inch wrench, remove the two 1/4
inch diameter capscrews from the engine pulley
bushing.
b) Insert the capscrews into the tapped holes in the
bushing flange. Tighten progressively until the bushing
disengages from the pulley.
c) Insert the 1/4 inch diameter capscrews into the
tapped holes in the pulley. Tighten progressively until
the bushing applies tension to the pulley.
d) Using the straightedge for reference alignment
purposes, tap the engine/electric motor pulley/bushing
into proper position.
e) Tighten the 1/4-inch diameter capscrews
progressively with the torque wrench to 95 inch
pounds. FIGURE 37.

f) Recheck alignment as outlined per the beginning of
Step 8.
9) Apply increased belt tension by progressively
tightening the take-up capscrews against the engine
crankcase/electric motor thrust plate.
a) Recheck V-belt alignment.
b) Check belt tension with the spring scale or belt
tension tool midway between the engine/electric motor
and driveshaft pulleys. Belt deflection should measure
approximately 3/16 inch at 3-7/8 to 5-1/2 pounds force.
FIGURE 38.
c) If belt tension and alignment is within specifications,
torque the engine/electric motor attachment
capscrews to 20 ft lbs (27 Nm.)
d) Recheck V-belt tension and alignment.
10) Install the belt guard to the main frame. Install the
flat washers and self-locking hexagon nuts. Torque the
nuts to 35 ft lbs (47 Nm.). Determine that all safety
related decals affixed to the belt guard are fully
readable. If any decal is not fully readable, replace
with a factory approved, replacement part only.
