frame 4 TM 9-2320-209-34-2-1 1. 2. 3. 4. 5. 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. GO TO FRAME 5 Table 10-7. Bearing Wear Limits (The letter T shows a tight fit and the letter L shows a loose fit.) Size and Fit of New Parts Wear Limit Number Item/Point of Measurement (inches) (inches) 1 amd 2 to 4 Fit of bearing on shaft 0.0000T to 0.0015T None 3 to 5 Fit of bearing in sleeve 0.0032L to 0.0056L None 10-66
