Check that bearing assemblies (1 and 2) and bearing (3) are not damaged.

Refer to para 10-8.

Using inside micrometer, measure inner diameter of cones of bearing assemblies

(1 and 2). Note measurements.

Using outside micrometer, measure outer diameter of outer shaft end of spur

gear pinion (4). Note measurement.

Subtract measurement made in step 3 from measurement made in step 2. Check

that fits of bearing assembly cones (1 and 2) to spur gear pinion (4) are

within limits given in table 10-7.

If fits of cones of bearing assembly are not

within limits given, get new parts for worn one.

Do steps 2 through 4 again and check that fits of bearing (3) to hypoid

drive gear (5) and sleeve (6) are within limits given in table 10-7. Get new

parts for parts worn beyond limits.
