UNIVERSAL

UNIVERSAL TENSIONING GAUGE FOR CAMBELTS

This tensioning gauge can be used to adjust the tension on the cam belts where the movement of the timing belt is measured by load (Nm). Suitable for use on Cam belts with various belt thickness (For belts other than 5mm thickness see Cam Belt Size below)

• Easy to use

• Clear incremental marking with knurled knob for precise measurement

• Dual scale allows reading from top or bottom of tool (Large and small numbers for compatibility)

ALWAYS USE MANUFACTURERS’ RECOMMENDATIONS FOR CAM BELT TENSION AND POSITION OF MEASUREMENT. (E.g. between the timing gear and the water pump pulley).

INSTRUCTIONS

To check tension

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 belt 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 is on the required tension setting. Use the

increments on the 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 internal slide is not visible it is likely it has been covered by the Cam Belt is too tight – by slackening the tensioning pulley the internal slide should appear)

7. Adjust as necessary

the knurled knob and is

To adjust tension

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 tool

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 6mm

and

Cam Belt Load 4.5daN Cam Belt Deflection 3.5mm

Then

Tension Setting = 16.0mm +1mm = 17.0mm Optimum Tension = 13.0mm +1mm = 14.0mm
