WARNING
Cleaning compound (MIL-PRF-29602) may cause irritation to the eyes or skin. Use in
well-ventilated areas and keep away from heat and open flame. Wear protective goggles
and clothing. In case compound comes in contact with:
Eyes, flush immediately with water.
Skin, wash with soap and water.
Failure to comply may result in personnel injury or death.
1.
Clean all metal parts with cleaner.
WARNING
Do not exceed 40 PSI (280 kPa) when using compressed air for drying components.
Failure to comply may result in serious injury to personnel.
2.
Dry parts with compressed air.
END OF TASK
INSPECTION
NOTE
Two different tolerances are given when replacing driven gear and shaft. If new parts are
used the clearance between driven gear bushing and shaft is 0.001 to 0.0025 in. (0.0254 to
0.0635 mm). If used parts are being used the maximum clearance is 0.0035 in
(0.0889 mm).
1.
Check driven gear shaft (Figure 2, Item 5) for damage. Replace damaged parts.
2.
Install driven gear shaft (Figure 2, Item 5) into front cover (Figure 2, Item 1).
3.
Using depth gauge, verify shoulder on shaft is flush to 0.020 in (0.508 mm) below finished face of front
cover.
4.
Remove shaft (Figure 2, Item 5) after inspection/verification has been completed.
5.
Inspect driven gear and bushing (Figure 2, Item 4) and shaft (Figure 2, Item 5).
a.
Using micrometer, verify clearance between used driven gear bushing (Figure 2, Item 4) and shaft
(Figure 2, Item 5) is within tolerance of 0.001 to 0.0035. in (0.0254 to 0.0889 mm).
b.
Using micrometer, measure diameter of shaft (Figure 2, Item 5).
c.
Using inside micrometer, measure inside diameter of driven gear bushing (Figure 2, Item 4).
d.
Subtract measurement obtained in Step b from measurement in Step c to obtain clearance specified in
Step a. Replace damaged parts.
