MAINTENANCE
SPARE DRIVE BELT REMOVAL
(USING REPLACEMENT DRIVE BELT)
The JWN-SERIES Ride-On Power Trowel is equipped with
a replacement drive belt (spare) carrier, which is mounted
on the inboard side of the left-side gearbox . Make sure that
there is ALWAYS a spare drive belt in the drive belt carrier
before the trowel is placed on a slab to finish concrete.
In the event of a drive belt failure, the spare (replacement)
drive belt can be used for quick replacement at the job site
for continued trowel operation.
1. To replace an existing drive belt with the spare drive
belt, remove the 2 bolts that secure the spare belt
holder to the left-side gearbox adapter plate. (Figure
17) Take care not to contaminate the replacement drive
belt with grease or dirt.

removed from the sheaves/grooves of the clutch and
lower pulley
4. Slide spare drive belt over the CV-joint (Figure 18) an
onto the lower drive pulley.
