TOOTH CONTACT
After bringing the backlash within specification by changing the
secondary driven bevel gear shims, it will be necessary to check
tooth contact.
• Remove the drive bevel gear assembly from the crankcase.
• Clean and degrease the secondary drive bevel gear teeth,
and apply a coating of machinist's layout dye or paste to sev-
eral teeth.
• Reinstall the secondary drive bevel gear assembly, with cor-
rect shim, onto the secondary gear housing.
• Rotate the secondary driven bevel gear several turns in both-
directions.
• Remove the secondary drive bevel gear from the crankcase,
and observe the tooth contact pattern made in the dye or
paste.
• Compare the tooth contact pattern to the examples as shown
in 1, 2 and 3.
• If tooth contact is found to be incorrect, the shims of the sec-
ondary drive bevel gear and secondary driven bevel gear
must be changed, tooth contact should be re-checked until
correct.

After the tooth contact adjustment is made, the back-
lash must be re-checked, as it may change. Refer to
the backlash checking sub-section, and readjust until
both backlash and tooth contact are correct.
