HOW TO USE A BELT TENSION GAUGE
Before adjusting the belt tension:
1� Throttle engine down to an idle and disengage the clutch. (This is shown in gure 1 for a electric clutch. If your machine
has a mechanical clutch you will need to manual disengage your clutch with the handle.)
2� Shut off the engine, remove the key.
DANGER/CUT and PINCH HAZARD: Shut power unit off and install lockout devices before any maintenance is
performed�
3� Remove the belt guard.
4� If maintenance is required, loosen the engine bolts, remove the belt, and x before setting belt tension.
5� Inspect and/or repair the following:
• Grease and oil on the belt: Grease and oil on a belt will cause rapid deterioration. Clean oil and grease from the
sheaves, wipe the belt with a clean cloth
• Burrs and rust in the sheave grooves: Remove burrs and rust
• Wear, damage, and misalignment of the sheaves and sprockets. Replace if excessively worn, frayed or soft
• Belt clearance and shaft misalignment: Adjust belt guard and shaft
Use a V-Belt tension gauge to set the belt tension by following these steps:
NOTE: Always install the same type of belt when installing new belts.
6� Measure belt span (see gure 1).
7� Position large O - ring on the tester scale at this measured length (see gure 2).
8� Slide the small O - ring ush with the barrel of the tester (see gure 3).
9� Place the large end of the tester on one belt, at the center of the span. Apply a sufcient force to tester to deect the
belt so that the large O - ring is ush with the other belts. If this is a single belt drive, use a straight edge as a reference.
10� Read the deection force from the position of the small O - ring on the plunger.
11� Compare this force with the value given (see table 1).
12� If the force is below the recommended value, increase the drive center distance to provide greater belt tension.
Reduce the center distance if there is too much force.
