General

This TASK gives the procedure for the inspection of the Roller bearing outer assembly. For the other parts of PTO drive shaft bearing and support, refer to TASK 72-32-05-200-000 (INSPECTION/CHECK-000).

All Fig/item numbers in parentheses in the procedure agree with those used in the IPC.

The policy that is necessary for inspection is given in the SPM TASK 70-20-01-200-501.

All the parts must be cleaned before any part is examined. Refer to the SPM TASK 70-11-22-300-503.

All the parts must be visually examined for damage, corrosion and wear. Any defects that are not identified in the procedure must be referred to IAE.

Do not discard any part until you are sure there are no repairs available. Refer to the instructions in repair before a discarded part is used again or oversize parts are installed.

Parts which should be discarded can be held although no repair is available. The repair of a discarded part could be shown to be necessary at a later date.

All parts must be examined to make sure that all repairs have been completed satisfactorily.

The practices and processes referred to in the procedure by the TASK numbers are in the SPM.

Bearings failing inspection may not be repaired or refurbished if;

They have been subjected to overheating because of loss of oil, the inner ring spinning on its hub, a compartment fire, or skidding.

They were involved in a major engine fire.

Procedure

    1. SUBTASK 72-32-05-110-058 Clean the Roller Bearing Outer Assembly

    1. Clean the roller bearing outer assembly. Refer to TASK 72-32-05-100-000 (CLEANING-000).

    2. SUBTASK 72-32-05-220-085 Visually Examine the Roller Bearing Outer Assembly for Surface Damages

    1. Refer to Figure.

    2. Visually inspect, without magnification, the bearing and its components, checking in particular for defects as shown in the SPM TASK 70-29-01-290-501.

    3. Surface damages on the race ways of inner and outer ring are not accepted.

    3. SUBTASK 72-32-05-220-086 Dimensionally Inspect the Roller Bearing Outer Assembly

    1. Refer to Figure.

      2. Examine the outer diameter at location 1.

        1. If the diameter is between 2.1258 and 2.1259 in. (53.994 and 54.000 mm)

        1. Accept

        2. Less than 2.1258 in. (53.994 mm)

        1. Reject

      3. Examine the under roller diameters at location 2.

        Use IAE IAE 2J12621 Plug gage 1 off.

        1. If the diameters are between 1.4187 and 1.4190 in. (36.033 and 36.043 mm)

    1. Refer to Figure.

      2. Check if the outer ring shows sign of having been overheated. Check must be made at the side face of outer ring use a ROCKWELL A (HRA) Tester or equivalent.

        1. If the hardness is between HRA 81.8 and 83.4

        1. Accept

        2. Out of Step

        1. Reject

      3. Remove raised metal.

    5. SUBTASK 72-32-05-110-059 Demagnetize the Roller Bearing Outer Assembly

    1. Demagnetize the bearing. Refer to the SPM TASK 70-11-22-300-503.

    2. Examine the bearing for residual magnetism.

    6. SUBTASK 72-32-05-620-054 Preserve the Roller Bearing Outer

    1. Clean the bearing by dipping in the compound.

    2. Preserve the bearing in an assembled state by dipping in the compound. Refer to the SPM TASK 70-29-01-290-501.
