WARNING!

The maximum working load (MWL) for the 35.2 PT Radial Winch is 650 Kg (1433 lb)
Subjecting the winch to loads above the maximum working load can cause the winch to fail or

Installation and Maintenance Manual

Installation

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.

Maintenance

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 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

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.

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.

Once the winch is completely disassembled, clean the parts: use a basin of diesel oil to soak
metal components and 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.
