SWING MOTOR GEARBOX MAINTENANCE (T1/02)
RRT-T1/02 SINGLE-STAGE, VERTICALLY MOUNTED GEARBOX:
CHECKING FLUID LEVELS
An elbow fitting (with an oil expansion tank and an oil breather/filler plug in it) is located in the top side of the gearbox.
The oil expansion tank should rise above the very top of the gearbox, and the fluid level should be kept at just less
than half way up the expansion tank. See Figure 1.
If a separate lube reservoir is used (it is connected to the gearbox with a hose),it must be kept at half full.
FLUID TYPE
Use EP80-90 Gear Fluid in gearbox and lube reservoir (if used).
FILLING THE GEARBOX WITH FLUID
Fill the gearbox through the oil breather/filler plug located in the top of the oil expansion tank. See Figure 1.
If a lube reservoir is used, keep adding fluid to the lube reservoir until gearbox is full and lube reservoir remains at half
full. The filler cap has a built-in breather which allows air to escape as needed.
FLUID CAPACITIES
Fluid capacity of gearbox ............................ 9.09 quarts.
Fluid capacity of lube reservoir (if used) ......
2 quarts (keep at half full once gearbox is filled with fluid).
RECOMMENDED FLUID CHANGE INTERVALS
Fluid should be changed after the first 50 hours of machine operation, and every 400 hours after that. Drain plug is
located under gearbox mounting flange.
MOUNTING BOLT TORQUE
Gearbox mounting bolts should be torqued to 127 Ft. Lbs. of lubed torque. Use anti-seize lubricant 514-00700.
