2.1 Timing Belt Tension Check (Cam Box)

WARNING

• Turn off the main power before carrying out this work.

• Exercise extreme caution when working on the machine if the cam is

not at its origin (0 deg.). Recoil of the cam axis can endanger the

operator.

<4000 Type>

There are four timing belts in the cam box. With a finger flick the center of the timing

belt to start it oscillating. Measure the oscillation with a frequency meter and compare

the readout with the stipulated frequency values. Refer to figure below for belt location

and the figure for tension values.

• When measuring belt tension, make certain to set the tension pulley.

• Belts (c) and (d) are a set of two belts. Be sure to synchronize them.

• Even though belts (c) and (d) are a set, measure them one by one.
