STR46SPVG — MAINTENANCE (TROWEL)
Belt Changing Procedure
The belts need to be changed as soon as they show signs
of wear. Remember that all belts should be changed at the
same time. Do not reuse a belt under any circumstances.
Indications of excessive belt wear are fraying, squealing
when in use, belts that emit smoke or a burning rubber smell
when in use.
Under normal operating conditions, a set of belts may last
approximately six months. If you trowel is not reaching this
kind of life span for belts, there are some things to check
when you replace a set of belts.
Check to ensure that the belts are tensioned correctly. Next,
check to make sure that the lower drive pulley (Figure 18) is
aligned properly.
Your machine is equipped with a spare belt carrier (Figure 18). It
is located opposite the clutch, mounted on the fuel tank. Make
sure that there are belts in the carrier before the trowel is placed
on a slab to finish concrete.
To install new belts from the spare belt carrier, first cut off
the old belts. Next, remove the spare belt carrier by
unscrewing the two bolts that attach it to the fuel tank.
The next step is to loosen the four engine mounting bolts
and slide the engine toward the rear of the trowel. Slide the
first belt over the clutch and place it on the upper drive pulley,
then pull it down and place it on the lower drive pulley. Repeat
this procedure for the second belt.
Realign the engine as described in the Belt Tension
Adjustment Procedure, and replace the belts in the spare
belt carrier.
Replacing Spare Belts
After the spare set of belts has been installed on the clutch
pulley, it will be necessary to replace the spare set of belts
that were in the spare belt carrier.
To replace a spare set of belts, be prepared to disassemble
the
driveline.
The driveline is located directly under the spare belt carrier.
There are three bolts that need to be removed that will
disconnect the CV-joint from the gearbox coupler. Reference
Figure 18.
Once the CV-joint has been separated from the gearbox
coupler, push the CV-joint inward so that a gap exist between
the coupler and the CV-joint. Slide the replacement belts
between this gap, and place them onto the spare belt carrier.
Secure the spare belt carrier to the fuel tank.
