6.8 BELT MAINTENANCE
The correct drive belt tension is essential to ensure
that full motor power is transmitted to the compressor
unit. The belt tension is achieved by raising the
compressor unit which has the effect of increasing
belt tension. Refer to
Figure 6-10 and Figure 6-11 .
Belt tension must be re-adjusted 0.5 to 2 hours after
a new set of belts are fitted. This will ensure that the
belts have completed their initial stretch.
Subsequent to this, belt tension needs to be checked
and adjusted if necessary every 2000 hours for the
duration of the belt life.
There are two recommended methods for checking
the belt tension. The test methods will be detailed as
follows.

ELT TENSION MEASUREMENT WITH

PTIKRIK TENSION
METER
.
Refer to Figure 6-8 . Follow instructions as follows:
A. Ensure the indicator arm is pushed down prior to
starting.
B. Gently place the meter on the flat side of one belt
at the midpoint between the motor and compres-
sor unit pulleys.
C. Slowly press on the push pad. Avoid contacting
the meter with other fingers as this may affect the
reading.
D. Once a definite click is detected, immediately
release pressure and the indication arm will
remain in the measuring position.
E. Carefully lift the meter without moving indicating
arm.
F. Read the measurement at the exact point where
the top surface of the indicator arm crosses the
scale.
G. Rotate the motor pulley through at least one
complete revolution and measure the tension
again, recording the results.
H. Repeat G for a total of 3 measurements.
I. Average the three measurements to obtain the
true belt tension.
J. Repeat for remaining belts.
K. Compare the results to the belt tension specifica-
tion in Table 6-1 and adjust if necessary.
