Description 

The AxleTech PROC2715 and PRC2715 axle family

is a single speed planetary axle series. Key features

in this axle family are:
• Hypoid ring and pinion gearing in the 

carrier assembly.

• Carrier assembly available with standard differential or

a hydraulically actuated differential lock (HDL) option.

• Carrier available with trunnion feature option or

standard differential.

• Thrust screw standard in carrier shell.
• Axle with a “trunnion” feature option.
• Internal large diameter Wet Disc Brake for 

service braking.

• Standard cast housing or heavier cast housing.
• Axle housing has wet brake inspection port standard

when wet brakes are fitted.

• Internal brake actuation lines standard in the

heavy axles with wet disc service brake.

• A planetary system with 3 or 4 planetary pinions 

per wheel end assembly.

• A common lubrication sump throughout the axle.
• O-ring drain/fill/breather port plugs standard.
• Force cooling inlet and return ports are standard on

basic axle housing.

• Park/Emergency brake on carrier input is optional

on axles without trunnion option.

This manual covers the servicing of this axle family.

The carrier is covered separately in AxleTech 

maintenance manual 5.4. Refer to the “How to Order”

section to obtain copies of these maintenance 

manuals. Optional parking brake on carrier input is

covered separately in AxleTech maintenance 

manual 4A.
