4-20 SHAFT DRIVE
• Remove the final gear bearing case and final driven bevel
gear, and inspect the coated teeth of the driven bevel gear.
The contact patch should be as shown at right:
• If the tooth contact pattern is incorrect, as shown in 1, a thin-
ner shim 4 is needed between the final drive bevel gear
bearing and final gear case.
• If the tooth contact pattern is incorrect, as shown in 3, a
thicker shim 4 is needed between the final drive bevel gear
bearing and final gear case.
• If the tooth contact pattern is incorrect for either reason, the
appropriate shim must be installed, and the tooth contact pat-
tern rechecked by repeating the tooth coating procedure
above.
NOTE:
If it is necessary to adjust the shim 4 thickness between final
drive bevel gear bearing and final gear case, the final gear back-
lash may change, and should be re-checked according to the
procedure outlined under the Backlash Measurement sub-sec-
tion. Both adjustments may be needed until both backlash and
tooth contact are correct.
