Me Me Me Me Method A thod A thod A thod A thod A uses a pull scale and a strong cord approxi-
mately 8 ft. long. (See Item 11). Me Me Me Me Method B thod B thod B thod B thod B uses a Lb-in
torque wrench. Both methods measure torque to rotate.
(See Item 12).

spring scale, clamp the end yoke horizontally in a
soft-jawed vise. Attach one end of the cord to a bolt
hole in the pinion cage, wrap cord around pinion
cage and attach the outer end of the cord to the
spring scale. Rotate pinion cage by pulling scale.
Read scale during fourth revolution. Scale reading
must be between 3-10 Lbs (1.4-4.5 Kg) See

There are two methods of measuring pinion bearing
preload and both are acceptable. Mechanic's preference
and available tools should determine which method
is used.
