DEALER SERVICE

The information in this section is written for dealer service personnel. The repair described here requires special skills and tools. If your shop is not properly equipped or your mechanics are not properly trained in this type of repair, you may be time and money ahead to replace complete assemblies.

Before working underneath, disconnect drive- line, raise cutter, lock in transport position, and block cutter securely. Hydraulic system leak down and failure of mechanical or hydraulic system can cause equipment to drop.

Keep all persons away from operator control area while performing adjustments, service, or maintenance.

CAUTION

Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.

GEARBOX MAINTENANCE

NOTE: Read this entire section before starting any repair. Many steps are dependent on each other.

1.Fill gearbox with SAE 80W or 90W gear lube until it runs out the side level plug.

NOTE: Repair to this gearbox is limited to replac- ing bearings, seals, and gaskets. Replacing gears, shafts, and a housing is not cost effective. Pur- chasing a complete gearbox is more economical.

2.Inspect gearbox for leakage and bad bearings. Leakage is a very serious problem and must be corrected immediately. Bearing failure is indicated by excessive noise and side-to-side or end-play in gear shafts.

Seal Replacement

Recommended sealant for gearbox repair is Permatex® Aviation 3D Form-A-Gasket or equivalent.

Leakage can occur at the vertical or horizontal gaskets and shaft seals.

Leakage at the horizontal gasket or seal can be repaired without removing the gearbox from the cutter.

Seal Installation

NOTE: Proper seal installation is important. An improperly installed seal will leak.

1.Clean area in housing where seal outer diameter (OD) seats. Apply a thin coat of Permatex.

2.Inspect area of shaft where seal seats. Remove any burrs or nicks with an emery cloth.

3.Lubricate gear shaft and seal lips.

4.Place seal squarely on housing, spring-loaded lip toward housing. Select a piece of pipe or tubing with an OD that will sit on the outside edge of the seal but will clear the housing. Tubing with an OD that is too small will bow seal cage and ruin seal.

5.Carefully press seal into housing, avoiding distortion to the metal seal cage.

Pipe or tube must press at outer edge of seal.

Vertical Shaft Seal Repair (Spindle Gearbox)

Refer to Figure 14.

1.Disconnect and remove the rear driveline from the gearbox.

2.Remove vent plug (24) and siphon gear lube from housing through this opening.

3.Remove crossbar (see Crossbar, page 34).

4.Remove protective seal (8) and vertical shaft seal (18). Replace seal (18) with new seal (see Seal Replacement page 29).

Vertical seal should be recessed in housing. Horizontal seal (19) should be pressed flush with outside of housing.
