EN
14. The Vee belts must be of the same type,
size, and number to those originally tted and
specied.
15. Before tting new belts, check the pulley
grooves are free from score marks or sharp
edges. Also check the grooves for wear. Ensure
the pulleys are tight on their shafts.
Replacement
16. If replacement of the belts is necessary due
to premature failure, the cause should be
investigated and rectied before tted new
belts. Refer to servicing vee belts, fault nding.
17. The drive centre distance must be reduced
prior to installation so that new belts can be
tted without the use of force.
18. Under no circumstance must belts be prised
into the grooves as belts and pulley grooves
can be damaged by using sharp tools to stretch
the belts over the pulley rim.
19. The procedure for tting new belts is generally
the same as described for belt adjustment
except it is necessary to slacken o the drive
enough to remove the old belts and t the new
without damage. It may also be necessary to
remove more of the guarding to gain access.
