side, and a vented filler plug on the top. Refer to the parts drawing MHP0850 for additional information.
Function
The disc brake runs in an oil bath shared with the gearbox. The
disc brake housing is bolted to the winch frame. It anchors the
disc brake to the winch frame, and holds the oil that lubricates
the brake. A flexible diaphragm is positioned between the end
cover and the brake housing. When the winch control handle is
moved or the pendant button is pushed to payout the wire rope,
air pressure is introduced to the brake. The air pressure pushes
on the diaphragm, which then presses on a metal diaphragm
plate. The diaphragm plate transfers the force through three pins
to a pressure plate.

MANUAL BAND BRAKE ASSEMBLY - GENERAL INFORMATION
Description
The optional manual band brake for the FA5A winch is located
on the end of the winch drum next to the air motor. It consists of
a friction material lined steel band (the brake band) that
encircles and grips a brake surface on the winch drum, and a
manually operated engagement and release mechanism.
Section 2
(Dwg. MHP1030)
Handle and eccentric assembly

Refer to Dwg. MHP1037
The brake handle has a splined end that engages an eccentric
shaft passing through bearings in an brake bracket which bolts
(Dwg. MHP1043) to the winch upright. There are two needle bearings pressed
into the brake bracket, and are protected from contamination
Operation by ‘O’ rings that act as dirt exclusion seals.
The winch operator can engage the brake band at any time,
whether the winch drum is turning in the haul-in direction,
stationary, or turning in the payout direction. Moving the brake
handle towards the winch turns an eccentric shaft which
tensions the brake band, causing it to grip the brake surface and
prevent the winch drum from turning. The handle will “over-
center” and remain in the engaged position until released by the
operator.
To release the manual brake, the operator must pull the handle
away from the winch to the disengaged position allowing the
winch drum to rotate freely. The winch operator needs only to
apply light pressure (about 2.3 to 4.5 kg [5 to 10 pounds]) at the (Dwg. MHP1037)

AUTOMATIC BAND BRAKE - GENERAL INFORMATION
Description Piston Retainer

The optional automatic band brake for the FA5A winch is located
on the end of the winch drum next to the air motor. It consists of a
friction material lined steel band (the brake band) that encircles
and grips a brake surface on the winch drum, and a spring loaded
pneumatic release assembly.
Cylinder Cylinder Rod Springs Cover
(Dwg. MHP0984)
(B) Brake bracket and plunger assembly

The brake bracket and plunger assembly is bolted to the drum
side of the winch upright (next to the motor). Four capscrews
fasten the brake bracket to the upright. Three more capscrews
fasten one end of the brake band to the brake bracket. Inside the
Section 3
brake bracket is a plunger that is attached to the other end of the

brake band by an adjustment bolt. The adjustment bolt runs
(Dwg. MHP0983) through a pivot bar on the band and threads into the plunger. The
pivot bar allows the adjustment bolt to pivot slightly as the brake
Operation is tensioned and released.
The friction material lined steel band remains tensioned, gripping
the brake surface until the winch control valve or pendant control
is operated to haul-in or payout a load. When the winch is hauling Brake Bracket
in or paying out a load, air pressure applied to a cylinder assembly
releases the band brake and allows the winch drum to rotate Cylinder Rod
freely. When the operator returns the winch control valve handle
to the neutral position or stops operating the pendant control, the
air pressure is shut off and spring pressure tensions the brake,
preventing the winch drum from rotating.
Spring
Components
The automatic band brake consists of two main assemblies. The Roller
first consists of a brake band that encircles a brake surface on
one end of the winch drum. The second is a spring loaded Plunger
pneumatic release assembly that is activated by air pressure from
the winch control valve or pendant control. (Dwg. MHP1081)
Brake band
The brake band is composed of a flat steel strip formed into a NOTICE
circular shape and lined inside with a friction material. Capscrews Additional important parts that allow the band brake

controlled rate allowing the band brake to engage
promptly and without hesitation.
Function
The automatic band brake is spring actuated so that it is always
tensioned unless the winch operator moves the winch control
valve handle or operates the pendant control to haul-in or payout
a load. Springs inside the cylinder assembly push on a piston that
is connected to the cylinder rod. The cam shaped end of the
cylinder rod engages a plunger inside the band bracket. The
plunger is attached to the brake band by an adjustment bolt.
While the springs press on the piston, the cylinder rod moves the

stage is connected to the outboard upright through the output
shaft. This prevents planet carrier rotation. Rotation of the
second stage planet gears causes the reduction gearbox housing
to rotate. The housing is connected to the drum by the cover and
capscrews.
