9.6.1 Set the Drive Belt Tension
WARNING!
Never operate a machine with any guards
or shields removed. The machine is shown
here with guards and/or shields removed for
illustrative purposes only.
W001
Check the drive belt tension after every 50 hours of operation.
For accurate measurement use a drive-belt tension gauge. If a
gauge is not available, the following method can be used.
1.
Use your hand to check the drive-belt deflection. Press on
the top, center of the drive belt (
).
The drive-belt tension is correct when it does not deflect
more than 1/4"–3/8" (6 mm–10 mm). Adjust the tension
accordingly.
2.
If the drive belt tension requires adjustment, loosen (do not
remove) the four bolts (two on each side) that secure the
engine mount to the machine frame.
3.
Turn the drive-belt tension bolt to adjust the drive-belt
tension:
-
Clockwise to increase the tension.
-
Counterclockwise to loosen the tension.
Be aware of the drive-belt alignment while adjusting the
drive-belt tension.
4.
When the drive-belt tension is correct, check the drive belt
alignment.
For instructions, see
Align the Drive Belt on page 39
.
5.
Complete one of the following:
• If the drive-belt alignment is correct, use a calibrated
torque wrench to tighten the four engine mount bolts to
33 lbf•ft (45 N•m)
, and then continue with step 6.
• If the drive-belt alignment is not correct, align the drive
belt.
6.
Install the drive-belt guard.
7.
Check the drive-belt tension after 10 hours of operation.
