2. Push­or­pull­down­on­the­belt­until­the­belt­has­deflected­0.18”­(4.5­mm).
3. Record push or pull down force. The force should be 5.5 - 5.9 lbs (2.5 - 2.7 kg) for a new belt and
4.7 - 5.1 lbs (2.1 - 2.3 kg) for a used belt.
4. Adjust the belt tension if the force falls outside of this range.
5. If adjustment is needed, loosen both pump mount bolts.
6. Adjust­the­pump­to­achieve­the­required­force­and­deflection
7. Tighten the pump mount bolts.

Worn or misaligned belts and sheaves in the power train
causes belt slippage, thus power loss. Keep the power

needed adjustment or replacement.

DANGER
!
Before attempting any type of maintenance, disengage clutch or cutter wheel engagement, wait for the
­cutter­wheel­to­come­to­a­complete­stop,­position­and­lock­the­cutter­wheel­in­the­transport­position,­turn­off­
engine, remove the ignition key, make sure the ignition key is in your possession, disconnect the battery, and
install the cutter wheel lock pin.
Do not over tighten the hydraulic pump belt. For best results use a good belt tension tester. 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.
DO NOT IGNORE THIS MAINTENANCE RULE!
New­belts­stretch­very­soon­and­must­be­adjusted­several­times­in­the­first­few­hours­of­operation.­Adjust­
after one hour of operation, then every four hours until the belts quit stretching.
MAINTENANCE
1. Check­tensioning­during­the­first­2­through­48­hours­of­run-in­operation­especially.
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.
