Introduction
This manual gives technical information on winch installation and maintenance, including
disassembling and reassembling.
This information is DESTINED EXCLUSIVELY for specialised personnel or expert users.
Installation, disassembling and reassembling of the winch by personnel who are not experts may
cause serious damage to users and those in the vicinity of the winch.
Harken®accepts no responsibility for defective installation or reassembly of its winches.
In case of doubt the Harken®Tech Service is at your disposal at [email protected]

Maximum working load
WARNING!
The maximum working load (MWL) for the 40.2 PT Radial Winch is 850 Kg (1874 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
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
You can find the icon on the skirt to identify the drive gear
position.
Once you have chosen the correct mounting position for the winch on the deck proceed with
installation.

C. Bolt the base of the winch to the deck using ve M6 Socket Head (SH) bolts for Procedure 1 or ve
hexagonal headed M6 bolts for Procedure 2 (neither is supplied by Harken®), 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 sufcient 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

order, and apply the products indicated in the section on maintenance.
NOTICE
Before closing the winch, make sure the holes and drainage channels in the base of the winch
are not obstructed.
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.
