Correcting Tooth Contact
 NOTE: If tooth contact pattern is comparable to the
correct pattern illustration, no correction is neces-
sary.
If tooth contact pattern is comparable to an incorrect pat-
tern, correct tooth contact according to the following
chart.
Tooth Contact

Contacts at Root

Shim Correction
Decrease Shim Thickness
Increase Shim Thickness
 NOTE: To correct tooth contact, steps 1 and 2 (with
NOTE) of "Correcting Backlash" must be followed
and the above "Tooth Contact/Shim Correction" chart
must be consulted.
CAUTION
After correcting tooth contact, backlash must again be
checked and corrected (if necessary). Continue the cor-
recting backlash/correcting tooth contact procedures
until they are both within tolerance values.
CRANKSHAFT ASSEMBLY
Measuring Connecting Rod
(Small End Inside Diameter)
 NOTE: The crankshaft and connecting rod is a
non-serviceable assembly. If any component is out of
specification, the assembly must be replaced.
1. Insert a snap gauge into the upper connecting rod
small end bore; then remove the gauge and measure
it with micrometer.
2. Maximum diameter must not exceed specifications.
Measuring Connecting Rod
(Small End Deflection)
1. Place the crankshaft on a set of V-blocks and mount a
dial indicator and base on the surface plate. Position
the indicator contact point against the center of the
connecting rod small end journal.
2. Zero the indicator and push the small end of the con-
necting rod away from the dial indicator.
3. Maximum deflection must not exceed specifications.
Measuring Connecting Rod
(Big End Side-to-Side)
1. Push the lower end of the connecting rod to one side
of the crankshaft journal.
2. Using a feeler gauge, measure the gap between the
connecting rod and crankshaft journal.
