Figure 31: Jackshaft Tension Bolts
17. Fully tighten all four jackshaft bearing bolts and
reattach the grease line to the jackshaft bearing.
18. Loop the engine belts around the jackshaft sheave.
Keep them slightly loose. DO NOT tighten fully.
19. Start the saw and let it idle (very slow speed!) while
adjusting the tracking of the polychain belt.
20. Slightly loosen two of the four jackshaft bearing
bolts. The bolts being loosened must be from the
same bearing!
21. Facing the front of the jackshaft, carefully and slowly
adjust the jackshaft belt tension bolt on the same
side as the slightly loosened bearing to place the
belt at the exact center of the polychain sprocket.
DO NOT over-tighten the belt during this
process!
When adjusting the left bearing, turn the
tension bolt clockwise a very small amount to move
the belt to the left, or turn the bolt counterclockwise
a very small amount to move the belt to the right.
When adjusting the right bearing, turn the tension
bolt clockwise a very small amount to move the belt
to the right, or turn the bolt counterclockwise a very
small amount to move the belt to the left.
Note: If
adjusting one bearing only isn’t working to center the
belt, adjust both bearings separately
22. Retighten all loose jackshaft bearing bolts.
.
23. Turn off the engine.
24. Turn both engine belt tension bolts (two large bolts
at front of engine mount) clockwise to fully tighten
the engine belts. Both bolts must be at the same
height once the belts are tightened. Test the belt
tension and readjust as necessary. Refer to
Appendix C for additional information on belt tension
settings.
25. Retighten all four engine mount bolts.
Tensioning the Engine Belts
1. Loosen all four engine mount bolts.
2. Turn both engine belt tension bolts (two large bolts
positioned vertically (CC110-SS) or horizontally
(CC110D-DC) at front of engine mount) clockwise to
tighten the engine belts. Both tension bolts must be
at the same height/length once the belts are
tightened. Test the belt tension and readjust as
necessary. Refer to Appendix C for additional
information on belt tension settings.
3. Retighten all four engine mount bolts.
Replacing the Engine Belts
1. Remove the outboard housing from the engine
(seven bolts).
2. Loosen all four engine mount bolts.
3. Turn both engine belt tension bolts (two large bolts
positioned vertically (CC110-SS) or horizontally
(CC110D-DC) at front of engine mount)
counterclockwise to loosen the engine belts.
4. Remove the belts from the engine sheave and from
the jackshaft sheave.
5. Replace the transmission drive belt if necessary.
Refer to the Replacing the Transmission Drive Belt
6. Loop and align the new belts around the jackshaft
sheave and then around the engine sheave.
section.
7. Turn both engine belt tension bolts clockwise to
tighten the engine belts. Both bolts must be at the
same height/length once the belts are tightened.
Test the belt tension and readjust as necessary.
Refer to Appendix C for additional information on
belt tension settings.
8. Retighten all four engine mount bolts.
9. Secure the outboard housing to the engine.
Tensioning the Transmission Drive Belt
1. Loosen the bolt securing the tensioner base to the
frame.

Tensioner Base and Bolt
2. Turn the square tensioner base counterclockwise to
tighten the belt. Note: Replace the belt when it can
no longer be tensioned .
