Spare Drive Belt Replacement

To replace a spare drive belt, be prepared to disconnect the CV-joint from the left-side gearbox. See Figure 21.

NOTICE

It will be necessary to disconnect the CV-Joint from the left-side gearbox coupler.This means the removal of the three screws that secure the CV-Joint to the gearbox.

1.Place the trowel on suitable supports and observe all safety precautions.

2.Remove Left-side End Grate and open Left "Clamshell"

3.Remove the three screws that secure the CV-joint to the left-side gearbox coupler.

4.Once the CV-joint has been separated from the left-side gearbox, push the CV-joint inward so that a gap exists between the gearbox and the CV-joint (Figure 21). Slide the spare V-belt between the gearbox coupler and the CV-joint. Avoid contaminating the replacement belt with grease or oil when sliding it between the CV-Joint and gearbox coupler.

5.Place the spare drive belt inside the drive belt carrier, and secure the spare belt carrier to the inboard side of the left gearbox.

6.Install the three screws that secure the CV-joint to the left-side gearbox coupler.

Left Side

Gearbox

The HHX is equipped with a "CVT" type clutch which supplies torque to both the left and right gear boxes.

The function of the CVT, (Continuously Variable Transmission), is to automatically deliver the correct amount of torque required by the trowel under all load conditions. This enables the trowel to deliver the necessary torque for float pan applications and the high rotor speeds required for burnishing concrete.

The Driven Pulley is a variable pitch pulley type, (Figure 22) connected by a drive belt.

The Drive Pulley uses centrifugal force (Figure 23 and Figure 24) to create a belt squeeze force transmitted at the pulley faces.This condition functions as an automatic clutch.
