Output Bevel Gears
Bevel Gear Backlash Adjustment
The amount of backlash is influenced by driven bevel gear
position more than by drive bevel gear position.
Remove the output drive idle gear (see Output Drive
Bevel Gear Removal).
Set up a dial gauge [A] against the output drive shaft
spline groove to check gear backlash.
To measure the backlash, turn the shaft clockwise and
counterclockwise slightly so as not to move the mate gear.
A rod can be inserted through the lower hole of the hous-
ing and into contact with driven gear. This m ay help to
hold it still. The difference between the highest and low-
est gauge reading is the amount of backlash.
If the backlash is not within the limit, replace the shim(s)
at the driven bevel gear.
Change the thickness a little at a time.
Recheck the backlash, and readjust as necessary.
Output Bevel Gear Backlash
Standard: 0.05 0.11 mm (0.0020 0.0043 in.) (at
output drive shaft spline)
Tooth Contact Adjustment
Tooth contact location is influenced by drive gear position
more than by driven gear position.
Clean any dirt and oil off the bevel gear teeth.
Apply checking compound to 4 or 5 teeth on the output
driven bevel gear.
NOTE
Apply checking compound to the teeth i n a thin, even
coat with a fairly stiff paint brush. If painted too thickly,
the exact tooth pattern may not appear.
The checking compound must be smooth and firm with
the consistency of tooth paste.
Special compounds are available from automotive sup-
ply stores for the purpose of checking differential gear
tooth patterns and contact. Use this for checking the
bevel gears.
Turn the output driven shaft for 3 or 4 turns in the drive
and reverse (coast) directions, while creating a drag on
the drive bevel gear shaft.
Check the drive pattern and coast pattern of the bevel
gear teeth. The tooth contact patterns of both drive and
coast sides should be centrally located between the top
and bottom of the tooth, and a little closer to the toe of the
tooth.
If the tooth contact pattern is incorrect, replace the shim(s)
at the drive bevel gear and shim(s) at the driven bevel
gear, following the examples shown. Then erase the tooth
contact patterns, and check them again. Also check the
backlash every time the shims are replaced. Repeat the
shim change procedure as necessary.
NOTE
If the backlash is out of the standard range after chang-
ing shims, correct the backlash before checking the
tooth contact pattern.
