11. Remove the cap screws securing the oil strainer
cap; then remove the cap.
12. Remove the two cap screws securing the oil
strainer; then remove the strainer.
! CAUTION
Do not remove the remaining output shaft assembly
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.
13. To remove the assembly, remove the nut securing
the secondary drive gear and secondary driven
gear; then from the inside of the crankcase using a
rubber mallet, remove the output shaft assembly.
Account for the output shaft, two gears, a shim, a
washer, and the nut.

Crankcase Components
NOTE: Whenever a part is worn excessively,
cracked, damaged in any way, or out of tolerance,
replacement is necessary.
SECONDARY GEARS
NOTE: When checking and correcting secondary
gear backlash and tooth contact, the universal
joint 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 dial indicator so the tip is contacting a
tooth on the secondary driven bevel gear.
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
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.)
