TM 9-2320-365-34-11-17. 11K SELF-RECOVERY WINCH (SRW)Figure 1-17. 11K Self-Recovery Winch (SRW)When specified, the vehicle is equipped with an 11K Self-Recovery Winch (SRW) (1, Figure 1-17) mounted on the rightframe rail. The 11K SRW is rated for 11,000 lbs (48,924 N) pull when the winch drum has one full layer of cable. Onefull layer of cable is the minimum amount of cable that may be left on the drum when using the SRW. Pulling capacityis reduced with each layer of cable that is added to the winch drum. Pulling capacity with seven full layers of cableon the winch drum is 6,780 lbs (30,157 N). The 11K SRW cable may be routed to the front or rear of the vehicle forrecovery operations. The 11K SRW is equipped with a fail-safe brake which is spring applied and hydraulicallyreleased. The fail-safe brake is automatically applied when hydraulic pressure falls below 270 psi (1,862 kPa). Thefail-safe brake will hold the load until hydraulic pressure is restored. The winch control valve functions as a throttlingvalve when cable is being payed out. The winch control valve controls the flow of fluid to the winch motor. When cableis being pulled in, the winch control valve acts as a free flow check valve. The winch control valve is preset at thefactory and is not to be adjusted under any circumstances.Change 1 1-23
