Repairs

Hydraulic Reel Motor

IMPORTANT: When performing maintenance pro- cedures on the cutting units, store the cutting unit reel motors in support tubes on the frame to prevent damage to the hoses. Do not raise suspension to transport position when the reel motors are in the holders in the traction unit frame. Damage to the motors or hoses could result.

Removal

1.Park machine on a clean and level surface, lower cutting units completely to the ground, stop engine, en- gage parking brake, and remove key from the ignition switch.

2.Remove basket from carrier frame.

3.Loosen flange head screws that secure the hydrau- lic motor to the motor adapter plate. Rotate motor clock- wise, and remove motor.

4.Place protective plastic cap (see Special Tools) into the hole in the motor adapter plate.

Inspection

1.Check reel drive coupler splines for wear. Replace if necessary (see Reel Removal and Installation in this chapter of this manual).

Installation

1.Coat spline shaft of the motor with clean No. 2 multi- purpose lithium base grease.

2.Install the flange head screws for the reel drive mo- tor into the motor adapter plate and leave approximately 1/2 inch (12.7 mm) of threads exposed on each screw.

3.Install motor by rotating the motor clockwise so the motor flanges clear the flange head screws.

4.Rotate the motor counterclockwise until the motor flanges are encircling the flange head screws. Tighten flange head screws.

Backlapping (Units without Optional Backlap/Variable Reel Speed Kit)

CAUTION

Be careful when backlapping the reel because contact with the reel or other moving parts can result in personal injury.

1.Remove reel motors from the cutting units and cut- ting units from the lift arms and pull frame (see Cutting Unit Removal and Installation).

2.Connect the backlapping machine to the cutting unit by inserting a piece of 3/8–inch socket extension drive into the splined reel drive coupling.

3.Attach backlap motor or drive to the socket exten- sion.

4.Follow instructions and procedures for backlapping in the Toro Service Training Book, Sharpening Reel and Rotary Mowers, part no. 80300SL.

Note: For a better cutting edge, run a file across the front face of the bedknife when the lapping operation is completed. This will remove any burrs or rough edges that may have built up on the cutting edge.
