To Tighten Belts
1. Loosen the four engine bolts.
2. Then locate the engine plate adjustment screws, on
the back of the engine.
3. Next loosen the nylon locknuts and jamnuts.
4. Turn all nylon locknuts counterclockwise an equal
number of turns to pull the engine backward until cor-
rect belt tension is attained. Maximum belt play
should be from 1/2” to 3/4” (13mm to 19mm) at the
center of the span. New belts sould be re-tensioned
after the first 10 to 12 hours of operation.
5. Retighten all jam nuts and locknuts.
To Replace Belts
1. Remove Belt Guard.
2. Loosen the four engine mounting bolts.
3. Locate the two engine plate adjustment screws.
These screws are located in the rear of the engine.
4. Loosen al the jamnuts and nylon locknuts on the
engine plate adjustment screws.
5. Tighten the two jamnuts clockwise, this will push the
engine forward and relieve the belt tension.
6. Loosen set screws (a) and (b) on the flex coupler
assembly (c).
7. Remove six attaching bolts (d) on the inside of the
flex coupler assembly (e) and slide the flex coupler
mount (c) toward gearbox so as to allow the inside
spider assembly (e) to be removed intact.
8. Remove and install belts through opening created
by removal of (e).
9. Reverse procedure for assembly. Do not over tight
en the bolts on the flex coupler assemblies. Tighten
screws (n) so that washers (m) are compressed
halfway into discs.
NOTE:
Remember that new belts should be re-ten-
sioned after the first 10 to 12 hours of use. Maximum
belt play should be from 1/2” to 3/4” (13mm to 19mm)
at the center of the span.
