DEALER SERVICE

The information in this section is written for dealer ser- vice 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, read manual instructions, securely block up, and check stability. Secure blocking prevents equipment from drop- ping due to hydraulic leak down, hydraulic system failure, or mechanical component failure.

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. Proper oil level is between lowest ring and end of dipstick.

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.

NOTE: Bearing failure is indicated by excessive noise and side-to-side or end-play in gear shafts.

Seal Replacement (Figure 10)

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 improp- erly 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.
