Checking Tooth Contact

NOTE: After correcting backlash of the second-

ary driven bevel gear, it is necessary to check

tooth contact.

1. Remove the secondary driven output shaft assem-

bly from the left-side crankcase half.

2. Clean the secondary driven bevel gear teeth of old

oil and grease residue.

3. Apply a thin, even coat of a machinist-layout dye

to several teeth of the gear.

4. Install the secondary driven output shaft assembly.

5. Rotate the secondary driven bevel gear several

revolutions in both directions.

6. Examine the tooth contact pattern in the dye and

compare the pattern to the illustrations.

Correcting Tooth Contact

NOTE: If tooth contact pattern is comparable to

necessary.

If tooth contact pattern is comparable to an incorrect

pattern, correct tooth contact according to the follow-

ing chart.

Tooth Contact

Contacts at Top

Contacts at Root

NOTE: To correct tooth contact, steps 1 and 2

(with NOTE) of "Correcting Backlash" must be fol-

lowed and the above "Tooth Contact/Shim Correc-

tion" chart must be consulted.

! CAUTION

After correcting tooth contact, backlash must again be

checked and corrected (if necessary). Continue the

correcting backlash/correcting tooth contact proce-

dures until they are both within tolerance values.
