Figure 26: 2 of 4 Jackshaft Bearing Bolts
5. To ensure safety, carefully remove the jackshaft
from the saw with the help of a second trained
operator. DO NOT try lifting the jackshaft off the saw
alone.
6. Remove all six bolts (four on front of plate, two on
bottom of plate underneath frame) from the skid
plate. Remove the plate.
7. Remove two of the four blade shaft bearing bolts.
The bolts being removed must be from the same
bearing! Loosen the remaining two blade shaft
bearing bolts. DO NOT remove them.
8. Remove the old belt from the blade shaft.
9. Fit a new polychain belt around the blade shaft from
the same side as the two removed blade shaft
bearings bolts. Slide the belt to the center of the saw
and fit it around the blade shaft’s polychain sprocket.
Bring the belt up through the hole on the frame
base.
10. Retighten all four blade shaft bearing bolts.
11. Reinstall the skid plate at the front of the saw (using
six bolts).
12. To ensure safety, carefully lift the jackshaft with the
help of the second trained operator and fit the
jackshaft through the polychain belt. Rest the
jackshaft on the jackshaft mounts and fit the belt
around the jackshaft’s polychain sprocket.
13. Retighten all four jackshaft bearing bolts.
14. Turn both jackshaft belt tension bolts (two large bolts
at front of jackshaft mount) clockwise to tighten the
polychain belt. The bolts must be at the same height
once the belt is tightened. Test the belt tension and
readjust as necessary. Refer to Appendix C for
additional information on belt tension settings.

15. Retighten all four jackshaft mount bolts.
16. Loop the engine belts around the jackshaft sheave.
Keep them slightly loose. DO NOT tighten fully.
17. Start the saw and let it idle (very slow speed!) while
adjusting the tracking of the polychain belt.
18. Slightly loosen two of the four jackshaft bearing
bolts. The bolts being loosened must be from the
same bearing!
19. Using a pry bar, push the loose bearing forward or
backward to place the belt at the exact center of the
polychain sprocket. When adjusting the left bearing
(facing front of saw), pry the bearing backward to
move the belt toward the left, or pry the bearing
forward to move the belt toward the right. When
adjusting the right bearing (facing front of saw), pry
the bearing backward to move the belt toward the
right, or pry the bearing forward to move the belt
toward the left.
Note: If adjusting one bearing only
isn’t working to center the belt, adjust both bearings
separately
