Installation and Maintenance Manual
Maximum working load
WARNING!
The maximum working load (MWL) for the 46 Rewind™ 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.
Outline
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.

Installation and Maintenance Manual
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 nal 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.
The winch can be installed following one of the two procedures below (Procedure1 or Procedure 2).
Before starting the Installation procedure, set the knob in the following position:

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.
Below is a reduced scale diagram.
The drilling cut out template is available on the Harken®website, www.harken.com
B. Remove the winch and drill the ve 8.5 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,

spanner and tighten other nut with second spanner. Take
special care not to turn the central spindles. Be careful not
to turn central spindles. These instructions apply when
assembling and disassembling. We recommend using a
torque wrench so as to obtain a torque equal to and no
greater than 10 Nm (88 in-lb).

46 Rewind ™ Radial Winch
Installation and Maintenance Manual
Maintenance
Washing
Winches must be washed frequently with fresh water, and in any case after each use.
Do not allow teak cleaning products or other cleaners containing caustic solutions to come into
contact with winches and especially anodised, chrome plated or plastic parts. Do not use solvents,
polishes or abrasive pastes on the logos or stickers on the winches. Make sure that the holes and
drainage channels in the base of the winch are not obstructed so that water does not collect.
Maintenance table
Winches must be visually inspected at the beginning and end of every season of sailing or racing.
In addition they must be completely overhauled, cleaned and lubricated at least every 12 months.
After an inspection, replace worn or damaged components. Do not replace or modify any part of
the winch with a part that is not original.
WARNING!
Periodic maintenance must be carried out regularly. Lack of adequate maintenance
shortens the life of the winch, can cause serious injury and also invalidate the winch
warranty. Installation and maintenance of winches must be carried out exclusively by
specialized personnel.
In the case of doubt contact Harken®Tech Service at techser[email protected]
WARNING!
Make sure that the power is switched off before installing or carrying out maintenance on
the winch.
