GEARBOX REPAIR
Read this entire section before starting any repair. Many steps are dependent on each other.
Repair to this gearbox is limited to replacing bearings, seals, and gaskets. Replacing gears, shafts, and a housing is not cost effective. It is more economical to purchase a complete gearbox if repair to anything other than replacement of bearings, seals or gaskets is required.
Fill gearbox with SAE 80W or 90W gear lube until it runs out the side level plug.
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 Perma- tex® Aviation 3D
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.
Inspect gearbox for leakage and bad bearings.
Leakage is a very serious problem and must be cor- rected immediately.
Seal Installation
NOTE: Proper seal installation is important. An improp- erly installed seal will leak.
