DANGER
!
Before attempting any type of maintenance,
disengage clutch, wait for the disc/drum to come to a
c omplete stop, turn off engine, remove the ignition key,
make sure the ignition key is in your possession, install
the disc/drum lock pin, and disconnect the battery.
NOTICE
Every month, the beltshield needs to be removed and
the belts need to be checked and adjusted. For best
results use a good belt tension tester. The slot in the
beltshield is for a quick daily check of the belt tension.
NOTICE
Do not over tighten the hydraulic pump belt. Most all
pump failures result from too much side load on the
pump shaft. Too much belt tension is very easy to
detect inside a failed pump. Pumps with this condition
will not be covered under warranty.
GENERAL RULES FOR TENSIONING
1. Check tensioning during the first 2 through 48
hours of run-in operation especially.
2. Over tensioning or under tensioning shortens
belt and bearing life.
3. Keep belts free from foreign materials that may
cause the belt to slip.
4. Make V-drive inspection on a periodic basis.
Never use belt dressing as this will damage the
belt and cause early failure.
5. Belts should never be forced over the sheave.
Allow enough room for belts to slip on.
6. Always make sure sheaves are aligned properly.
MAIN DRIVE BELTS
1. Follow all pre-maintenance shut down procedures.
2. Locate the center of the belt span between the
sheaves.
3. Push or pull down on each poly band belt until
the belt has deflected 3/8" (9.5 mm).
4. Record the push or pull down force on each poly
band belt. The force should be 60 to 64 lbs. (27.2
to 29.0 kg) for machines up to 150 Hp; or 48 to
51 lbs. (21.8 to 23.1 kg) for machines with 150
Hp or above.
5. Adjust the belt tension if the force fall outside
of this range.
PUMP DRIVE BELTS (IF EQUIPPED)
1. Follow all pre-maintenance shut down procedures.
2. Locate the center of the span between sheaves.
3. Push or pull down on the belt until the belt has
deflected 1/4" (6.4 mm).
4. Record push or pull down force. The force should
be 12 lbs (5.4 kg).
5. Adjust the belt tension if the force falls outside
of this range.

BELT TENSION
!
If belts are not properly adjusted belts will slip,
glaze over, and be ruined. THIS FAILURE IS NOT
COVERED BY WARRANTY!
NOTICE
DO NOT IGNORE THIS MAINTENANCE RULE
New belts stretch very soon and must be adjusted
several times in the first few hours of operation.
Adjust after one hour of operation, then every four
hours until the belts quit stretching. Failure to do this
will cause the belts to burn and fly off. THIS FAILURE
IS NOT COVERED BY WARRANTY!
NOTICE
It is a good practice to rotate the sheaves during
tensioning. Then recheck deflections. The belts may
need to be tightened again.
