FRONT WINCH MAINTENANCE (Contd)

AUTOMATIC WINCH BRAKE TESTING

NOTE

Assistant is needed to perform the following procedure.

Park test vehicle (1) at top of steep grade facing downhill, place gear shift lever (10) in NEUTRAL,

pull parking brake lever (13) to apply parking brake, and chock wheels (TM 9-2320-386-10).

NOTE

Perform steps 2 and 3 only when new winch is installed in order

to burnish brake and lubricate gears.

Pay out winch cable (2) for 5 minutes at engine idle (TM 9-2320-386-10).

Allow brake band to cool for approximately 1-1/2 hours.

Park secondary vehicle (3) at bottom of steep grade facing test vehicle (1).

WARNING

Wear leather gloves when handling cable. Do not let cable run

through hands. Broken or rusty wires can cause injury to personnel.

Never stand between test vehicles during winch operations. Assistant

must remain in secondary vehicle to engage service brake if cable

snaps or automatic brake fails. Failure to do this may result in injury

to personnel.

Direct all personnel to stand clear of winch cable during winch

operation. A snapped winch cable may result in injury to personnel.

Do not exceed 1,500 rpm engine speed during winch operation. Use

hand throttle to avoid erratic engine speed that could cause injury to

personnel.

CAUTION

Do not proceed with front winch operation if oil level is low.

Damage to internal components may result

Do not use front winch to pay out line loads greater than

3,000 lb (1,362 kg) for any distance greater than 10 ft (3.1 m).

Damage to equipment may result.

Pull out and rotate drum lock knob (8) 1/4-turn clockwise, and release into shallow slot on nut (9).

NOTE

If winch cable chain hook will not pass through lifting shackle,

disassemble lifting shackle to remove winch chain hook.

Remove winch cable chain hook (6) from right lifting shackle (7), and pass hook (6) through left

lifting shackle (5).

WARNING

When hooking up for winching operations, position throat (open

part) of hook upward in case overloading straightens out hook.

Failure to do so may result in injury to personnel.

CAUTION

Refer to TM 9-2320-386-10 for safe working loads.
