Cutter Drive Belt – Remove/Install.
•
Pull the Cutter Arm ‘F’ ‘back’.
Remove the top section of the Connecting Rod
Bearing Cap, and allow the Connecting Rod ’
G ’
to swing ‘downwards’.
•
Remove the Nuts ‘ H ’ from the Crankshaft
Bearing Bolts.
NOTE
Use a ’crowfoot’ wrench to hold the head of the
rear bearing bolt. (It is difficult to reach because
of the Tension Spring).
Use a ‘pry-bar’ ‘
J ’, to lever the bearing ‘down’ sufficient
to remove the Drive Belt.
Install the new Drive Belt and re-assemble in the
reverse order. Take care to tighten all fasteners to their
correct torque.
To adjust the tension of the Drive Belt:
•
With the Drive Motor mounting bolts ‘loose’,
turn the Drive Belt Adjusting Nut ‘
K ’ clockwise
to tension the belt, until there is ¼ to 3/8 inch
de-flection at a point midway between the Drive
Motor and the Crankshaft sheaves.
•
Tighten the mounting bolts locknuts and
replace the cover plate.
IMPORTANT
Do not over tension the Drive Belt, as this may result in
premature wear and motor bearing failure.
Check the belt tension after 20 to 30 hours of operation.
