12.Replace body if the inside diameter of the gear pockets exceeds 1.713 in. (43.5 mm).
Inspection (Fig. 46) 1. Remove all nicks and burrs from all parts with an emery cloth.
13.Make sure both plugs are secure if they or the backplate is not being replaced. Reassembly (Fig. 46)
Use eye protection such as goggles when using compressed air. 2. Clean all parts with solvent. Dry all parts with compressed air. 3. Inspect drive gear shaft for a broken or chipped keyway. 4. Inspect drive gear and idler gear shafts at the bushing points and seal area for rough surfaces and excessive wear. 5. Replace drive gear or idler gear if the shaft diameter in the bushing area measures less than 0.748 in. (19.0 mm). A single gear may be replaced separately. 6. The drive gear and idler gear face should be free of excessive scoring and wear.
1. If replacing the relief valve assembly, install ball, spring, shim, O−ring, and plug into the backplate. Hand tighten plug and then torque from 10 to 12 ft−lb (13.6 to 16.3 N−m). 2. Coat O−ring lightly with petroleum jelly and install in groove on the front plate. 3. Apply a thin coat of petroleum jelly to both gear pockets of the body. Install alignment pin into body. 4. Align matchmarks and slip body onto front plate until alignment pin is engaged. 5. Dip idler gear and drive gear into clean hydraulic oil and slip into front plate bushings. 6. Coat O−ring lightly with petroleum jelly and install in groove on the back plate. 7. Install alignment pin into back plate.
7. Replace drive gear or idler gear if gear width is less than 1.140 in. (29.96 mm).
8. Align matchmarks and slip back plate over gear shafts onto body until alignment pin is engaged.
8. Make sure that retaining rings are in the grooves on both sides of the gear for both the drive gear and idler gear.
9. Hand tighten cap screws. Torque cap screws in a crisscross pattern from 25 to 28 ft−lb (33.9 to 38.0 N−m).
9. Break sharp edges of gear teeth with emery cloth. 10.Replace backplate and frontplate if bushing inside diameters exceed 0.755 in. (19.2 mm). The bushings are not available as replacement items. 11. The face of the backplate and frontplate should be free of excessive scoring. Replace if scoring a depth of 0.0015 in. (0.038 mm).

10.Place washer over the drive shaft into the front plate housing. Apply a liberal coat of hydraulic oil to the oil seal. Install oil seal over the drive shaft being careful not to cut the rubber seal lips. 11. Place 1−1/16 inch O.D. sleeve over the drive shaft and press in the oil seal until the retaining ring groove appears. 12.Press retaining ring into the housing using the sleeve until it seats in the groove.
