IMPORTAnT!
These Instructions are provided as a guide only. Always refer to the vehicle manufactures’ service instructions or a
proprietary manual to establish the correct procedure and data.

WARnInG!
Incorrect or out of phase camshaft timing can result in contact between the valve head and the piston crown. This will
cause damage to the engine.
2. InTRODUcTIOn
ensures accurate measurement of belt tension. Clear increment and dual scale for ease of use. Tension chart guide is included. Suitable for
belts of varying thickness.
3. InSTRUcTIOnS
The Belt Tension Gauge is suitable for use on camshaft drive belts, and
serpentine drive belts. It is designed for ease of use and can be used to
check the tension on a variety of belts where the movement of the belt is
measured by load. There is a clear increment and a dual scale for accurate
measurement of the belt tension.
nOTE:
Always follow the manufacturer’s data for the belt tension requirements
and the correct position of where the belt tension should be measured.
The Belt Tension Gauge is set for 5mm thick belts but can measure various
belt thickness.
3.1.
checking the belt tension
3.1.1.
Fit the Belt Tension Gauge on the belt at the correct location as
detailed by the manufacturer for load testing.
3.1.2.
Obtain the manufacturer’s data for belt deflection (mm) and load.
(dan)
3.1.3.
Using the table supplied, find the correct tension setting.
3.1.4.
Turn the knurled knob until the bevelled edge is on the required tension setting, the increments shown are for precise setting.
3.1.5.
The belt tension can now be read from the internal slide. This reading can now be compared to the optimum tension readings on the
table overleaf.
3.1.6.
Adjust the belt to the correct tension as required.
3.1.7.
If the belt to be tightened is thicker that 5mm, simply add the difference to the tension setting and to the optimum tension.
For example; (example shown in the shaded area on the table)
Belt thickness = 6mm
Belt load = 4.5 dan
Belt deflection = 3.5mm
The tension setting = 16mm + 1mm = 17mm
optimum Tension = 13mm + 1mm = 14mm
