Introduction - Technical characteristics
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 EL/HY Performa™ Winch is 1450 Kg
(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.

Performa™Winch 50.2 STP EL/HY
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.
After correctly positioning the nal pinion 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.

3. Slide off the assy socket n°29 and the cover
n°28. Pay attention to the o-ring in the socket.
5. Remove the stripper arm n°26 by
rotating and lifting it. 6. Lift off the drum n°23
2. Unscrew the central screw ( 2Nm/18 in-lb)
4. Unscrew the three screws n°27
(4Nm/35 in-lb)

Winch installation procedure
Carry out the Procedure, 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 6.2 mm diameter holes.
C. Bolt the base of the winch to the deck using ve M6 Socket Head (SH) bolts (no 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 thewinch,make surethe holes and drainage channels in the base ofthe winch are notobstructed.
Positioning the self-tailing arm
Position the self-tailing arm so that the line leaving the winch is led into the cockpit.
Motor installation procedure
WARNING!
Make sure that the power is switched off before installing or carrying out maintenance on
the winch.
Once you have installed the winch on the deck, proceed with motor installation.The motor can be coupled to
the winch in different positions. Check the space available below deck and choose the suitable position.
Tools needed
A number ve hex key
A number six hex key (only for vertical electric motor)
A number ten hex key (only for hydraulic motor)
Two number thirteen wrenches
Motor installation procedure
1. Position the ange (see Page 10)
3. Position the reduction gear and motor
2. Tighten six M6 precote coated screws
( 8 Nm/ 71 in-lb)
4.Tighten the two screws ( 8 Nm/ 71in-lb).
Be sure to align the ange.

NOTICE
Before positioning the ange, check to make sure
that seal is seated correctly.
After winch is assembled and before sailing, test the powered winch functioning: insert the lock-in
winch handle in the handle socket and check that the disconnect rod must disconnect gearbox.
Electric equipment
To guarantee greater efficiency in terms of safety and long life, for every winch model is mandatory
to install the Dual Function Control Box.
To fasten the Dual Function Control Box containing solenoids to bulkhead or wall, for all
installation details and for all electric wiring schemes, refer to the Dual Function Control Box
manual.
WARNING!
Before installing and using the device, read carefully the Dual Function Control Box manual
available on web site www.harken.com
