NOTE
The ratio of the line load - pressure is evaluated at nominal ow rate.
The performance is evaluated measuring the pressure and ow on the motor ports.
The performance data are based on oil with a viscosity of 35mm2/s [165 SUS] and
temperature of 50°C [120°F].

Maximum working load
WARNING!
The maximum working load (MWL) for the 46.2 ST Radial Winch is 1300 Kg (2866 lb)
Subjecting the winch to loads above the maximum working load can cause the winch to fail or
pull off the deck suddenly and unexpectedly during high loads causing severe injury or death.

Installation and Maintenance Manual - Mod.D
Installation
The winch must be installed on a at area of the deck, reinforced if necessary to bear a load equal
to at least twice the maximum working load of the winch.
It is the installer's responsibility to carry out all structural tests needed to ensure that the deck can
bear the load.
Harken®does not supply the screws needed to install the winch since these may vary depending
on the deck on which it is to be installed.
It is the installer's responsibility to choose the correct screws taking account of the loads they will
have to bear.
Harken®assumes no responsibility for incorrect installation of its winches or for an incorrect choice
of mounting screws.
DANGER!
Incorrect installation of the winch may cause severe injury or death. Consult the yard that built
the boat in the case of doubt over the correct positioning of the winch.
WARNING!
Failure to use the correct number and type of mounting fasteners or failure to ensure the
correct deck strength can result in the winch pulling off the deck suddenly and unexpectedly
during high loads causing severe injury or death.
WARNING!
Verify the entry angle of the sheet. This must be 8° with tolerance of
±2°, to avoid sheet overrides and damaging the winch or making the
winch inoperable leading to loss of control of the boat which can lead to
severe injury or death.
WARNING!
Mount the winch on the deck so that the drive gear is positioned where
the sheet enters the winch drum.
Incorrect position of drive gear can weaken winch leading to failure
which can cause an accident leading to severe injury or death.
NOTICE
For winch STA, STC and STCW versions only
You can find the icon on the skirt to identify
the drive gear position.
After correctly positioning the nal drive gear with respect to the load, check that the motor,
gearing, electrical wiring and/or hydraulic pipes can be housed below decks. To help nd the
optimal compromise, remember that, to make the installation of the motor easier, It can be coupled
to the winch in different positions.
Once you have decided the correct mounting position for the winch on the deck and checked the
space available below deck, proceed with the installation.

Installation and Maintenance Manual - Mod.D
The winch can be installed following one of the two procedures below (Procedure1 or Procedure 2):
Procedure 1
To install the winch you must remove the drum and use bolts as described ahead.
Tools needed: One medium at-bladed screwdriver
To identify the various parts, refer to the exploded view at the end of this Manual.
Torque to apply when assembling
1. Pull out the disconnect rod n°21 2. Unscrew the central screw ( 2Nm/18 in-lb)
3. Slide off the assy socket n°31 and the cover
n°30.
Pay attention to the o-ring in the socket.
4. Unscrew the three screws n°29
(4Nm/35 in-lb)

5. Remove the self-tailing arm n°28 by rotating
and lifting it.
1. Remove the skirt n°2 with the help of the
screwdriver placed as shown by the symbol
6. Lift off the drum n°24
2.Take off the base n°2
Winch STA, STC and STCW versions:
Install the winch on the deck in the position you have chosen, keeping in mind the limits described
on page 4 and using socket head (SH) bolts.
Winch STBBB and STCCC versions:
Install the winch on the deck in the position you have chosen, keeping in mind the limits described
on page 4 and using socket head (SH) bolts or hexagonal headed bolts (HH).
Procedure 2 (not pertinent for ST BBB/CCC versions)
To install the winch, remove the winch skirt and use hexagonal headed (HH) bolts.
Tools needed: One medium at-bladed screwdriver
To identify the various parts, refer to the exploded view at the end of this Manual.
See (paragraph on installation) the limits described on page 6 and using socket head (SH) bolts.

Winch installation procedure
Carry out Procedure 1 or Procedure 2,then install the winch on the deck in the chosen position.
NOTICE
Before drilling the deck, check the space available below deck for the ange and the motor
A. Position the base of the winch on the deck and mark the position of the holes or use the
drilling cut-out template at the point where you have decided to place the winch.

B. Remove the winch and drill the ve 8.2 mm and a 80 mm diameter holes.
C. Bolt the base of the winch to the deck using ve M8 bolts (not supplied by Harken®) as
described at Procedure 1 or Procedure 2, correctly chosen for the thickness and type of the boat
deck. Consult the yard that built the boat in case of doubt.
WARNING!
To install the winch on the deck, use only bolts in A4 stainless steel (DIN 267 part11).
Bolts made of other materials may not have sufficient strength or may corrode which can result in
winch pulling off deck suddenly and unexpectedly during high loads causing severe injury or death.
NOTICE
To mount winches on the deck, do not use countersunk bolts.
D. Fill the mounting holes with a suitable marine sealant.
E. Remove the excess adhesive/sealant from the holes and base drainage channels
F. Reassemble the winch following the steps in Procedure 1 or Procedure 2 in the reverse order,
and apply the products indicated in the section on maintenance.
