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 [e-mail]
This Manual is available only in English. If you do not fully understand the English language, do
not carry out the operations described in this Manual.

Maximum working load
WARNING!
The maximum working load (MWL) for the 50.2 ST Performa™ Winch is 1450Kg (3197 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.
Once you have chosen the correct mounting position for the winch on the deck proceed with
installation.

Installation procedure
Carry out the Procedure, then install the winch on the deck in the chosen position.
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 8.2 mm diameter holes.
C. Bolt the base of the winch to the deck using ve M8 Socket Head (SH) bolts (not 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 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 of the Procedure in the reverse 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.
Positioning the self-tailing arm
Position the self-tailing arm so that the line leaving the winch is led into the cockpit.
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, on the stickers on the winches or on
any anodized, chrome plated and plastic surfaces.
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.

If it is necessary to replace any jaws of the winch, proceed as follows:
Inspect balls inside the drum and carefully check the correct position; if it is necessary to put back
any balls, push balls in the race (as shown below):
Once the winch is completely disassembled, clean the parts with a degreasing that does not leave
residues, proper to clean metal components; rinse plastic parts in fresh water. Once you have done
this, dry the parts with cloths that do not leave residue.
Inspect gears, bearings, pins and pawls for any signs of wear or corrosion.
Carefully check the teeth of gears and ring gears to make sure there are no traces of wear.
Check the roller bearings and check there are no breaks in the bearing cages.
Replace worn or damaged components.
Carry out maintenance on components using the products listed below.
For more information on which products to use where, refer to the exploded diagram below.
Use a brush to lightly lubricate all gears, gear pins, teeth and all moving parts with grease.
