Jackshaft V-belts
- Check Tension
WARNING
A moving belt is very powerful and dangerous.
KEEP AWAY FROM MOVING BELT AT ALL
TIMES!
Extreme caution must be used to prevent death
or serious injury.
For the sake of safety, the belt guard cover must
always be in place when engine is running.
Before beginning to check or adjust the belt: shut-
down the machine, insure that all moving parts
have come to a halt, remove the key from the
ignition, and place the key in safekeeping.
NOTICE
When checking belt tension cutting wheel must
be free to turn. Therefore, check tension when
cutting boom is locked in the raised position,
rather than when cutting wheel is resting on the
ground.
Proper tension of the v-belt is achieved when the belt
can be depressed one belt thickness in the center of
the belt span when the belt is engaged. If adjustment
is out of alignment the following steps should be
followed.
1. Be sure the machine is hooked to a vehicle and
the parking brake is set. The transport block
should be in place.
2. Start engine and idle. Engage cutter wheel belt
and shut off engine. ( Before proceeding make
sure cutter wheel has come to a complete
stop.) Remove ignition key and place in safe
keeping. Partially disengage the belt tightener
to relieve the tension on the clevis pins.
3. Remove cotter pin from the clevis pin (1).
4. Remove clevis pin.
5. To tighten V-Belt, lengthen push rod.
6. To loosen V-Belt, shorten push rod.
7. Replace the clevis pin and check the belt.

jackshaft v-belts tension must be readjusted.
