Converter Drive Belt Deflection Adjustment
•
Disassemble the driven pulley (see Driven Pulley D isas-
sembly in the Converter System chapter).
If the belt deflection is more than 27 mm (1.06 in.), remove
the spacers to decrease it.
○
The rule-of-thumb is: 0.1 mm (0.004 in.) change in spacer
thickness equals about 1.3 mm (0.051 in.) change in belt
deflection.
If the adjustment cannot be done within the specified
range even if the shim is removed, replace the drive belt.
If the belt deflection is less than 22 mm (0.87 in.), add the
spacers [A] to increase it.
○
The rule-of-thumb is: 0.1 mm (0.004 in.) change in spacer
thickness equals about 1.6 mm (0.063 in.) change in belt
deflection.
NOTE
○
When using the plural spacers, install the thick spacer
to the movable sheave side and thin spacer to the fixed
sheave side.

•
Assemble the driven pulley (see Driven Pulley Assembly
in the Converter System chapter).
•
With the transmission in neutral, rotate the driven pulley
to allow the belt to return to the top of the sheaves before
measuring the belt deflection.
•
Measure the belt deflection again and repeat the above
procedures until it is within the standard range.
•
Using the flywheel & pulley holder and pulley holder at-
tachment, tighten the driven pulley nut.
