MT005A

5. Acceptable backlash range is 0.127-0.381 mm

(0.005-0.015 in.).

Correcting Backlash



NOTE: If backlash measurement is within the

acceptable range, no correction is necessary.

1. If backlash measurement is less than specified,

remove an existing shim, measure it, and install a
new thinner shim.

2. If backlash measurement is more than specified,

remove an existing shim, measure it, and install a
thicker shim.



NOTE: Continue to remove, measure, and install

until backlash measurement is within tolerance. Note
the following chart.

After backlash and tooth contact are within specifica-
tions, apply red Loctite #271 to the driveshaft threads and
driven output shaft threads; then using new nuts, tighten
the output shaft nut to 59 ft-lb and the output yoke nut to
74 ft-lb.

CRANKSHAFT ASSEMBLY



NOTE: The crankshaft and connecting rod is a

non-serviceable assembly. If any component is out of
specification, the assembly must be replaced.

Measuring Connecting Rod
(Small End Inside Diameter)

1. Insert a snap gauge into the upper connecting rod

small end bore; then remove the gauge and measure
it with micrometer.

CC290D

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.

CC289D

3. Acceptable gap range must not exceed specifica-

tions.

Measuring Crankshaft (Runout)

1. Place the crankshaft on a set of V blocks.

2. Mount a dial indicator and base on the surface plate.

Position the indicator contact at point 1 of the crank-
shaft.

Backlash Measurement

Shim Correction

Under 0.127 mm (0.005 in.)

Decrease Shim Thickness

At 0.127-0.381 mm (0.005-0.015 in.)

No Correction Required

Over 0.381 mm (0.015 in.)

Increase Shim Thickness
