11K SELF-RECOVERY WINCH (SRW)

11K SRW. When specified, the vehicle may be equipped with an 11K SRW mounted on

the right hand frame rail. The 11K SRW is rated for 11,000 lbs (48,924 N) pull when the

winch drum has one full layer of cable. Pulling capacity is reduced with each layer of cable

added to the winch drum. One full layer of cable is the minimum amount of cable that may

be left on the drum when using the 11K SRW. Pulling capacity with seven full layers of

cable on the winch drum is 6,780 lbs (30,157 N). For recovery operations, the 11K SRW

cable may be routed to the front or to the rear on all vehicles so equipped.

Hydraulic pressure to operate the 11K SRW is supplied by a single-stage hydraulic

pump mounted on the back of the PTO.

Placing the PTO switch in the on position causes the PTO drive gear to engage with

the transmission. When the PTO is engaged, it drives the single-stage hydraulic

pump.
