Belt Tension
Adjustment
Note: Belt tension and alignment are interrelated. Do not adjust one
without checking the other.
New Belt:
1. Turn the engine off; allow all moving parts to come to a complete stop.
2. Disconnect the spark plug wire.
3. Remove V-Belt Cover/belt guard. See Pic.15
4. Loosen four engine bolts and slide engine towards flywheel shaft.
5. Remove old belt and install new belt
6. Pull engine away from flywheel shaft to tension belt. Proper belt
tension is when 6.7 lbs of force at the mid-point of the belt results in a
deflection of 1/4in.
7. Re-tighten engine bolts.
8. Replace V-Belt Cover/belt guard and reconnect the spark plug wire.
To Retighten Belt:
1. Turn the engine off; allow all moving parts to come to a complete stop.
2. Disconnect the spark plug wire.
3. Remove V-Belt Cover/belt guard. (See Pic.16)
4. Loosen four engine bolts and slide engine away from flywheel shaft to
tension belt. Proper belt tension is when 4.6 lbs of force at the mid-
point of the belt results in a deflection of 1/4in.
5. Re-tighten engine bolts.
6. Replace V-Belt Cover/belt guard and reconnect the spark plug wire.
Note: Proper alignment is for the front and back of both sheaves (all 4
faces need to be in a straight line). Use a long straight edge to check
alignment.
WARNING:
Do not operate the machine without making sure all guards are in place after
servicing.
Note: New belts require a “break-in” period of approximately 2 hours.
Readjustment may be necessary after “break-in.”
