9.8.2 Set the Drive Belt Tension
IMPORTANT! Adjust the drive belt tensioning bolts evenly.
If the bolts are unevenly adjusted, you may have to align the
engine.
A drive-belt tension gauge, ruler, or tape measure is
necessary for this procedure. A drive-belt tension
gauge is the most accurate tool.
Check the drive belt tension after every 100 hours of
operation.
1.
Press on the top centre of the rotor drive belt and measure
the distance it moves. See
2.
Do one of the following:
• If the drive belt movement measures
between
1/4"
(6 mm) and
3/8" (10 mm)
, the drive belt tension is
correct.
You do not need to set the drive belt tension.
• If the drive belt tension is not correct, continue with the
following steps to set the drive belt tension.

Loosen (do not remove) the four bolts that attach the
engine mount to the machine frame. See

Use the drive-belt tensioning bolts to set the drive belt
tension. See
5.
Do steps 1, 2, and 4 again, until the drive belt tension is
correct.
6.
Tighten the four engine mount bolts.
7.
Do step 1 again.
8.
Do one of the following:
• If the belt tension is correct, continue with step 9.
• If the belt tension is not correct, do steps 3 to 7 again.
9.
Align the drive belt.
For instructions, see

.
