ÈV-BELT TENSION ADJUSTMENTS
This instruction is to be used for adjusting the belt tension on the following machine models:
A belt tension testing device (Milnor
®
part number 30T001) and a straight edge are required when using these
instructions.
ÊTension Settings
Set the o-rings on the tension testing device (FIGURE 1) as follows:
1. Move the upper o-ring to the topmost position, resting against the
bottom edge of the cap.
2. Find the proper Belt Deflection setting (by machine model and belt
function) in the appropriate table in this section.
3. Move the lower o-ring on the tension tester to this deflection setting
on the inches scale.
NOTE 1: The tension testing device is marked on one side in inches
and pounds and on the other side in centimeters and kilograms. All
values in the tables are in inches (in) and pounds (lbs).
NOTE 2: The instruction sheet provided with the tension testing
device should not be used. Use only the instructions provided herein.
NOTE 3: The reference (ref) codes shown in the tables are for factory
use only.
ÊBelt Tension Measurements
1. Place a straight edge along the top edge of the belt to be
tested so that it spans both pulleys. Place the tension
tester in the center of the belt and press down on the cap
until the lower o-ring is in line with the straight edge, as
shown.
2. Read the setting of the upper o-ring on the lbs scale of the
tension tester.
3. Compare this value with the acceptable range in the ap-
propriate table. If the belt is brand new (has never been
run), use the range in the Initial Tension column. If the
belt is not brand new, locate the acceptable range in the
Final Tension column.
4. If the reading on the tension tester is less than the range
shown in the table, the belt is too loose and must be tightened. If the reading is greater than the range shown
in the table, the belt is too tight and must be loosened. Adjust the belt until the reading falls within the ac-
ceptable range in the table.
