“Heavy Duty Graphtic Paper” for wet sump applications.

Superior energy capability,high and stable coefficientof friction and smooth engagement.

GENERAL A2 SERIES DATA:

1. Maximum operating pressure is 3,000 psi (206.4 Bar).

Pressure spikes or surges not to exceed 3,500 psi

(240.8 Bar). Surge pressure in excess of 3,500 psi (240.8 Bar) caused by spikes in the hydraulic system could shorten brake life and must be avoided.

2. Use only SAE grade 8 mounting bolts and torque to

80-90 lb. ft. (108-122N-m) for motor mounting.

3. PRECAUTION: Bench testing may cause distortion of

components or bolt failure. Mounting bolts must be used for supplemental clamping.

4. Minimum Release Pressure is defined as the hydraulic

pressure required to obtain full running clearance.

5. Cubic Inch Displacement is the volume of oil required

Model 9 Features

Power Wheel®

A2 Series Integral Parking Brake

Large tapered roller bearings allow increased axial and radial loading.

Double heat treat spindles provide toughness and increase fatigue life.

Bearing nut provides preload to optimize bearing life.

Ductile iron hubs provide added strength for resistance to impact loading.

High strength secondary casting helps resist shock loading.

Optimized gear geometry increases the contact ratio, which enhances gear life.

High strength gear material allows greater power density and improves gear life.
