Benefits

More positive seal to prevent

oil seepage during operation.

Easier to store o-rings verse a

paper gasket.

InterchangeabilityDesign Feature

Gear ratios, output shaft and

bearing, and mountingconfigurations are not changed.

Benefits

The hydraulic or aerodynamic

Maintenance ChangesLubrication Gearbox lubricant is changed to I SO

viscosity grade 46.

Spherical Roller Bearing Installation. Lubricate the upper housing bearing bores and bearing

outside diameters with gearbox oil.

Using machinist level ensure that the outer race of the

upper input shaft bearing is level before installing the

upper gearbox housing.

Use level on top of the upper gearbox housing while

lowering it into position.
