Stanley Black & Decker DS06 manual Motor Reassembly, Shafts, Service Instructions, Gear Housing

SERVICE INSTRUCTIONS

groove should be smooth as should the rest of the fl at surface.

The bore for the shaft seal should be smooth or oil leakage may occur.

GEAR HOUSING

Shake the gear housing and the two seal check balls (not shown) should rattle. If the seal balls do not rattle then they are probably plugged with contaminants and the gear housing will require replacement.

SHAFTS

The shaft diameter at the bearing and seal locations must be smooth. Grooves, roughness or a reduced diameter indicate fl uid contamination or damaged bushings. Grit particles may have been imbedded in the bushings grind- ing into the hardened shaft. If abnormal shaft wear as above occurs (more than normal polishing), replace both the shaft and associated bushings.

Also check the hydraulic system for excess contamination in the fl uid and for fi lter condition. Operating conditions may require changing from a 25-micron fi lter to an over- sized 10-micron fi lter.

MOTOR REASSEMBLY

Refer to the illustration below for correct placement of parts.

1.If the bushings (6) were removed from the valve handle (22) and the gear housing (4), install new bushings using a p/n 11918 bearing pusher. (NOTE: The bushing split line must face the center of the gear housing).

2.Grease and carefully install a new quad ring (90) into the seal liner (57). Grease and install a new o-ring (56) onto the seal liner. Install the seal liner into the valve handle assy (22). Replace the retaining ring (91).

3.To replace the bearing (92) onto the motor shaft (53), support the bearing inner race and press the motor shaft through the bearing inner race.

4.Place the valve handle assy on a smooth clean arbor press surface (protected from damage) with the large bear- ing bore facing up. Position the valve handle so a clearance hole exists for the insertion of the motor shaft.

5.Apply grease to the motor shaft, keyway and bush-

ing and then insert the motor shaft through the shaft seal. Using a socket with a diameter equal to the bearing O.D., press the bearing and motor shaft into place. Press only on the outer race.

6.Install the needle roller (54) in the keyway of the motor shaft. Use grease to keep the needle roller in place. Slide the drive gear (13) over the needle roller and shaft. Install the idler shaft (8) and gear (9).

7.Apply grease to the face seal o-ring groove; then install the o-ring (7).

8.Note the screw hole pattern on the rear gear housing and the valve handle. They will only assemble one way. With all parts aligned, carefully slide the gear housing as- sembly over the gears until it contacts the valve handle. Do not force parts together.

9.Turn the motor shaft manually to check for free rotation. Install the eight capscrews (1) and then recheck rotation.
