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.

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.
