Safety Tips
Before inspecting or changing belt drives, turn the equipment off and lock the controls if possible.
Never try to pry or roll belts into the pulley groove. Your hand could be pinched between belt
and pulley.
Always install guards before operating equipment to keep hands or clothing from being caught
in the drive.
Never operate belt drives above recommended speeds because serious damage to personnel
or equipment could result.
Do not operate equipment where pulleys and belts are badly out of alignment. The belt could slip
off the pulley.
Wear gloves to avoid cutting ngers on sharp metal edges when inspecting or changing belts or
pulleys.
Installing Belts and Pulleys
The procedures outlined in your equipment service manual should be followed carefully.
The following tips may also be helpful:
• Remove dust, dirt, grit, and rust. If an idler is involved, make sure it turns easily.
• Remove any buildup of paint or rust in the pulley grooves to prevent belt slippage
and belt wear.
• Replace pulleys that show wear along the sides. This can result in increased slippage
and shorter belt life.
• Replace all old belts with new belts of the same make or brand so the loads will be
equally distributed.
• Move the pulleys closer together by adjusting the drive tension adjuster, or move
the take-up idler pulley out of the way so the belt will simply slip into place.
• Check pulley and belt alignment using straightedge against outside edges of both
pulleys. All edges of both pulleys should touch the straightedge.
After the belts are installed, take up the slack with the adjustment until the belts are snug.
Belts should be just tight enough to prevent them from slipping under full load. Do not
over tighten. Belt tension should be re-checked after about 15 minutes of operation. If necessary
re-tighten belts.
Maintaining Belt / Pulley Drives
Misalignment will cause wear on the sides of v-belts.
Vibration during operation can cause belts to turn over.
Store equipment with belts inside or under cover to protect from weather which causes belts
to get dry and hard, resulting Premature wear.
Never use belt dressing which tends to collect dirt resulting in premature wear.
A squeal or chirp noise indicates belt slippage, possibly caused by improper tension or dirt in the
pulley groove.
The sound of belts slapping against the guard could be caused by improperly placed guard,
loose belts or excessive vibration.
