15K SELF-RECOVERY WINCH (SRW)
15K SRW. When specified, any vehicle except models M1084A1 and M1086A1 may be
equipped with a 15K SRW mounted on the right hand frame rail. The 15K SRW is rated
for 15,500 lbs (68,944 N) pull when the winch drum has one full layer of cable. Pulling
capacity is reduced with each layer of cable that is 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 15K SRW. Pulling capacity with seven full layers of cable on the winch drum is 9,090
lbs (40,432 N). For recovery operations, the 15K SRW cable may be routed to the front
on all vehicles so equipped. The 15K SRW cable may be routed to the rear of the vehicle
on models M1083A1, M1085A1, And M1090A1.

Hydraulic pressure to operate the 15K SRW is supplied by a three stage hydraulic
pump on model M1089A1 and a single stage hydraulic pump for all other models.
The hydraulic pump is mounted on the back of the PTO.
2.
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 hydraulic pump.
