Inspection (Fig. 56)
1.Remove all nicks and burrs from all parts with an emery cloth
CAUTION
Use eye protection such as goggles when using compressed air
2.Clean all parts with solvent. Dry all parts with com- pressed air.
3.Inspect drive gear (9) shaft for a broken or chipped keyway.
4.Inspect drive gear (9) and idler gear (8) shafts at the bushing points and seal area for rough surfaces and ex- cessive wear.
5.Replace drive gear (9) or idler gear (8) if the shaft in the bushing area diameter measures less than 0.748 in. (19.0 mm). A single gear may be replaced separately.
6.The drive gear (9) and idler gear (8) face should be free of excessive scoring and wear.
7.Replace drive gear (9) or idler gear (8) if gear width is less than 1.140 in. (29.96 mm).
8.Make sure that retaining rings are in the grooves on both sides of the gear for both the drive gear (9) and idler gear (8).
9.Break sharp edges of gear teeth with emery cloth.
10.Replace backplate (7) and frontplate (14) if bushing inside diameters exceed 0.755 in. (19.2 mm). The bush- ings are not available as replacement items.
11.The face of the backplate (7) and frontplate (14) should be free of excessive scoring. Replace if scoring a depth of 0.0015 in. (0.038 mm).
12.Replace body (12) if the inside diameter of the gear pockets exceeds 1.713 in. (43.5 mm).
13.Make sure both plugs (1) are secure if they or the backplate is not being replaced.
Reassembly (Fig. 56)
1.If replacing the relief valve assembly (19), install ball (5), spring (4), shim (3), O±ring (2), and plug (1) into the backplate (7). Hand tighten plug (1) and then torque from 10 to 12 ft±lb (1.38 to 1.66 kg±m).
2.Coat O±ring (11) lightly with petroleum jelly and install in groove on the front plate (14).
3.Apply a thin coat of petroleum jelly to both gear pockets of the body (12). Install alignment pin (13) into body (12).
4.Align matchmarks and slip body (12) onto front plate (14) until alignment pin (13) is engaged.
5.Dip idler gear (8) and drive gear (9) into clean hy- draulic oil and slip into front plate (14) bushings.
6.Coat O±ring (11) lightly with petroleum jelly and install in groove on the back plate (7).
7.Install alignment pin (13) into back plate (7).
8.Align matchmarks and slip back plate (7) over gear shafts onto body (12) until alignment pin (13) is en- gaged.
9.Hand tighten cap screws (15) and torque in a criss- cross pattern from 25 to 28 ft±lb (3.46 to 3.87 kg±m).
10.Place washer (18) over the drive shaft into the front plate (14) housing. Apply a liberal coat of hydraulic oil to the oil seal (17). Install oil seal (17) over the drive shaft being careful not tho cut the rubber seal lips.
11.Place 1±1/16 inch O.D. sleeve over the drive shaft and press in the oil seal (17) until the retaining ring groove appears.
12.Press retaining ring (16) into the housing using the sleeve until it seats in the groove.
