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 17) is aligned
properly.
Your machine is equipped with a spare belt carrier (Figure 17). 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.
T
o 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. See Figure 17.
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.
