key.
8. Remove the counterbalance shaft.
9. Using Crankcase Separator/Crankshaft Remover,
remove the crankshaft.

unless absolutely necessary. If the shaft is removed, the
shaft nut must be replaced with a new one and the shaft
must be re-shimmed.

SECONDARY GEARS
KC325

NOTE: When checking and correcting secondary
gear backlash and tooth contact, the output drive
flange must be secured to the front shaft or false
measurements will occur.
Checking Backlash

NOTE: The rear shaft and bevel gear must be
removed for this procedure. Also, always start with
the original shims on the rear shaft.
1. Place the left-side crankcase cover onto the left-side
crankcase half to prevent runout of the secondary
transmission output shaft.
2. Install the secondary driven output shaft assembly
onto the crankcase.
3. Mount the indicator tip of the dial indicator on the
secondary driven bevel gear (centered on the gear
MD1024
tooth).
4. While rocking the driven bevel gear back and forth,
note the maximum backlash reading on the gauge.
5. Acceptable backlash range is 0.05-0.33 mm
(0.002-0.013 in.).
Correcting Backlash

NOTE: If backlash measurement is within the
acceptable range, no correction is necessary.
1. If backlash measurement is less than specified,
remove an existing shim, measure it, and install a
new thinner shim.
2. If backlash measurement is more than specified,
remove an existing shim, measure it, and install a
MD1330
thicker shim.

NOTE: Continue to remove, measure, and install
until backlash measurement is within tolerance. Note
the following chart.
Backlash Measurement
Under 0.05 mm (0.002 in.)
At 0.05-0.33 mm (0.002-0.013 in.)
Over 0.33 mm (0.013 in.)
