INSTRUCTIONS
TO CHECK TENSION
1. SELECT CORRECT POSITION FOR TENSION MEASUREMENT AS RECOMMENDED BY THE
MANUFACTURER'S INSTRUCTIONS. (MEASUREMENTS ARE VISIBLE FROM BOTH SIDES
OF THE TENSIONER).
2. ATTACH TENSIONER TO CAM BELL WITH INTERNAL SLIDE VISIBLE FROM EITHER SIDE.
(IF USING THE REVERSE OF THE TOOL MAKE SURE THE SMALLER INCREMENTS ARE
USED FOR PRECISION SETTING)
3. CHECK THE MANUFACTURERS DETAILS FOR CAM BELT TENSION INCLUDING CAM BELT
DEFLECTION (MM) AND CAM BELT LOAD (DAN)
4. USING THE GRID BELOW FIND THE APPROPRIATE TENSION SETTING (AS SHOWN)
5. ROTATE THE KNURLED KNOB UNTIL THE BEVELED EDGE ISONTHE REQUIRED TENSION
SETTING. USE THE INCREMENTS ONTHE KNOB FOR PRECISE SETTING.
6. READ THE ACTUAL TENSION FROM THE INTERNAL SLIDE AND COMPARE IT WITH THE
OPTIMUM TENSION ON THE GRID. (IF THE INT ERNAL SLIDE IS NOT VISIBLE IT IS LIKELY
IT HAS BEEN COVERED BY THE KNURLED KNOB AND IS THE CAM BELT IS TOO TIGHT -
BY SLACKENING THE TENSIONING PULLEY THE INTERNAL SLIDE SHOULD APPEAR)
7. ADJUST AS NECESSARY
TO ADJUST TENSION
1. USING TENSIONING TOOL (AS APPROPRIATE) APPLY SUFFICIENT FORCE TO THE
TENSIONING PULLEY UNTIL THE SLIDING SCALE INDICATES THE CORRECT VALUE.
2. TIGHTEN THE LOCKING BOLT ON THE TENSIONING PULLEY WITH THE APPROPRIATE
CAM BELT SIZE
FOR BELTS THICKER THAN 5MM - ADD THE DIFFERENCE TO THE TENSION SETTING AND
OPTIMUM TENSION.
For example
If Cam Belt thickness is
and
Cam Belt Load
Cam Belt Deflection
then
Tension Setting
Optimum Tension
