MAINTENANCE (Continued)

Planet Gear Head Assembly (38) and the Planet Gear Head Spacer (41).

3.Using snap ring pliers, remove the Spindle Bearing Retaining Ring (45).

4.Stand the Gear Case on the table of an arbor press with the output spindle upward. Using a rod that neatly fits inside the internal hex of the Spindle (42), press the Spindle Assembly out of the Spindle Bearing (44).

Do not remove the Bearing in the following step unless you have a new replacement available for installation. The Bearing will be damaged by the removal process.

5.Invert the Gear Case on the table of an arbor press so that the end face having four notches makes contact with the table. Using a rod against the inner race of the Spindle Bearing, press the Bearing from the Gear Case.

6.If the Spindle Bearing Seat (46) must be replaced, use a small, thin blade screwdriver to spiral it out of the groove in the Gear Case.

Disassembly of the Motor

1.Using snap ring pliers, remove the Rear End Plate Assembly Retainer (23) from the shaft of the Rotor (27).

2.Pull the Rear End Plate Face Plate (22) and Rear End Plate Assembly (21) off the hub of the Rotor.

3.Lift the Cylinder (24) from the Rotor.

4.Remove the Vanes (28) from the Rotor.

5.Support the Front End Plate Assembly (29), as near the rotor body as possible, on the table of an arbor press and press the Rotor from the Front Rotor Bear- ing (31). Remove the Bearing from the Front End Plate.

Disassembly of the Housing

1.Pull the Reverse Lever (19) off the inlet end of the Motor Housing (1).

2.Using a #2 Phillips Head Screwdriver, unscrew and remove the Housing Screw (3).

3.Insert a 5/16” wooden dowel between 6 and 8 inches long, into the inlet end of the Motor Housing and push the Reverse Valve Assembly (4) out the motor end of the Housing.

4.Use a hooked tool to pull the Housing O-ring (2) out of the Motor Housing.

ASSEMBLY

General Instructions

1.Always press on the inner ring of a ball-type bearing when installing the bearing on a shaft.

2.Always press on the outer ring of a ball-type bearing when pressing the bearing into a bearing recess.

3.Whenever grasping a tool or part in a vise, always use leather-covered or copper-covered vise jaws to protect the surface of the part and help prevent distortion.

This is particularly true of threaded members and housings.

4.Except for bearings, always clean every part and wipe every part with a thin film of oil before installation.

5.Apply o-ring lubricant to all o-rings before final assembly.

6.Check every bearing for roughness. If an open bearing must be cleaned, wash it thoroughly in a clean, suitable cleaning solution and dry with a clean cloth. Sealed or shielded bearings should never be cleaned. Work grease into every open bearing before installation.

Assembly of the Housing

1.Lubricate the Housing O-ring (2) with o-ring lubricant and install it at the bottom of the cylinder bore in the Motor Housing (1).

2.Inspect the face and o-ring on the hub of the Reverse Valve Assembly (4) for nicks or damage. Replace the Reverse Valve Assembly if any damage is evident.

3.Lubricate the o-ring on the hub of the Reverse Valve Assembly with o-ring lubricant and insert the Assem- bly, o-ring end leading, into the cylinder bore of the Motor Housing. Push the Assembly toward the bot- tom of the cylinder bore until it “snaps” into its proper location.

4.Rotate the Valve inside the Housing until the threaded hole into the side of the Valve for the Motor Housing Screw (3) aligns with the hole in the Motor Housing.

5.Using a #2 Phillips Head Screwdriver, thread the Motor Housing Screw into the Reverse Valve Assem- bly through the Housing until the underside of the screw head stops against the Housing. Back the Screw out of the Valve between 1/4 and 1/2 turn.

6.Align the open end of the slot inside the Reverse Lever (19) with the head of the Housing Screw. From the inlet end of the Housing, slide the Lever onto the Housing, making certain the screw head enters the slot, and move it along the Housing until it stops against the housing shoulder.

7.Rotate the Lever to make certain the Valve only has slight resistance.

Assembly of the Motor

1.Place the Front End Plate (29) on the splined shaft of the Rotor (27) with the bearing recess away from the rotor body.

2.Place the Front Rotor Bearing (31) onto the shaft and using a sleeve or piece of tubing that contacts the inner race of the Bearing, press the Bearing onto the
