Installation and mantainance manual for Antal XT Winches
BEFORE YOU READ THIS GUIDE
The present Installation and Maintenance Manual contains important information for the
correct use of the XT winch and you are therefore advised to read it carefully before
using the product.
The present manual gives technical information for the installation and the maintenance
of the following XT winch models: XT4 4 /AL, X T4 4/CH, XT4 4R, X T48/AL, X T48/CH,
XT48R, XT52/AL, XT52/CH, XT52R, XT62/AL, XT62/CH, XT62R In case of technical
queries, contact [email protected].
Powered winches. The installation of powered XT winches does not pertain to the
purposes of this manual. For the sole maintenance operations, however, it is advised to
refer to the indications contained in the section 4 of this manual.

IMPORTANT CONCEPTS
Power. Winches are distinguished by power values. The ratio between the force exerted
on the handle and the power dispensed by the winch, is said power. For example: if a
winch has power 66, it means that when I exert a force 1 on the handle, I get a power of
recovery of 66 on the drum (theoretical value that disregards friction).
Recovery speed. To a high power of the winch, there corresponds a reduced recovery
speed. On the contrary, to a reduced power, there corresponds a high recovery speed.
Multi-speed. The use of a winch for the recovery of maneuvers requires both speed (in
the initial moment) and power (in the final moment). Thus, to maximize the effectiveness
of the winch, there are multi-speed winches.
Reduced speed. Recovery speed ratio can be direct or reduced. It is direct when one
turn of the handle corresponds to a complete revolution of the drum. On the contrary, the
speed is reduced when you need more turns of the handle to complete one revolution
of the drum. Thanks to a reduced speed, it does not ‘fatigue’ and recovery is ‘slower’.
The winches XT44, XT48, XT52 and XT62 all have two reduced speeds.

ABOUT XT WINCHES

4
USE
The XT winch is designed for the recovery of a maneuver (halyard, sheet or other line).
To use the winch, wind the maneuver with at least four turns around the drum of the
winch. After winding to the drum, the maneuver must enter through the ST arm between
the two self-regulating disks. In case of slippage of the maneuver, increase the number
of turns on the drum.
Diameter of the maneuver in the self-tailing. The lower disk of the self-tailing
automatically adapts to the diameter of the maneuver. The movement of the disk is
limited to a certain range of diameters for each winch. Lower diameters than those
allowed can cause slippage of the maneuver. Conversely, larger diameters may damage
the self-tailing. Refer to the table of the models to know the minimum and maximum
diameters of maneuvers for each winch.
Use of the winch. All XTs are self-tailing winches and therefore require the sole action
of the handle for the recovery of the maneuver. To operate the first power (high speed)
insert the handle at the top of the winch, then turn it counterclock wise. To operate the
second speed (high power), invert the rotation of the handle and turn clockwise.

Installation is the responsibility of professional personnel. The installer must ensure the
good state of the deck where the winch is to be installed. Antal assumes no responsibility
for an incorrect installation of the winch.
Warning: an incorrect installation of the winch may cause injuries or damages to things.
In case of doubt on how to properly install the winch, contact specialized personnel.
Respect the two following principles for the correct installation of the winch on the deck.
Position of the winch on the deck and Placement of the skirt. Only after you have applied
these two principles, procede with installation.

5
Position of the winch on the deck.
Before installing the winch you must
choose a location on the deck that
allows the maneuver which you
intend to use, to reach the winch at
an angle between 2 and 10 degrees.
Placement of the skirt.
Position the winch so that the output
gear is in the area shown in the figure,
i.e., tangent to the pull direction of the
maneuver.

TOOLS NEEDED
To install the winch, you will need: supplied key (K) for the opening of the upper ring (R),
drill, sealant, screws, bolts and washers.
Screws. Antal does not supply the anchoring screws needed to install the winch. The
length of the screws depends on the thickness of the deck. Use screws, washers and
bolts in stainless steel AISI 316. Pay attention to the type of screws. For XT44, XT48,
XT52 required UNI 5933 - hexagonal socket countersunk head screws; for XT62 required
UNI 5931 DIN 912. To learn the screw diameter, see table of technical characteristics
above.
INSTALLATION PROCEDURE
The installation of the XT winch
requires that you lift the drum. First of
all unscrew the upper ring (R) with the
provided key (K). Thus lift the drum
(D) to access the anchoring holes on
the skirt (S) of the winch.

Once you have determined
the location of the skirt on the
deck (see p.5), you can drill the
anchoring holes.
To determine the position of the
holes, mark the deck using the
winch’s skirt’s holes directly.
Alternatively, you can download
the drilling templates from the
internet, at www.antal.it.
Then drill the deck.
In order to prevent water
seepage, put sealant around the
anchoring holes.
Be careful not to obstruct with the
sealant the drainage channels at
the bottom of the winch.
Thus, tighten the bolts.
Once you have fixed the winch
skirt in the correct position, re-
insert the base and the drum.
The XT winches accept a number
of possible positions of the drum.
Choose the desired rotation
of the drum based on the
orientation of the ST arm.
The orientation of the ST arm
depends on where you want to
gather the maneuver.
Once the drum is positioned,
tighten the upper ring.

MAINTENANCE
Frequent maintenance. All XT winches should be washed frequently, and in any case
after each use, to avoid the accumulation of salt. Use plenty of fresh water and clean
it on all visible surfaces. Ensure the cleaning of the drainage channels placed at the
bottom of the winch, to avoid water stagnation.
Complete maintenance. With seasonal frequency XT winches should be inspected
visually inside.
Parts in need of maintenance. The most relevant parts are those subject to movement
and rubbing. These are the roller bearings, the gears and pawls, the stem and the inside
of the drum. For the complete maintenance of the winch, disassemble the winch in order
to access the relevant parts.
Antal Hydrolub. We recommend the use of Antal Hidrolub, a grease expecially made
for lubrication of winches and protection of aluminum parts in the marine environment
(Mod. HDR).
Cleaning. Remove old lubricant. In order to do so use a soft bristle brush and solvent
(use diesel in case you do not have other solvents).
Lubrication. It increases the performance and prolongs the life of the winch. Also, it
prevents the natural accumulation of salt to obstruct the inner mechanism. Also, if you
are using the Antal Hydrolub Grease, it also protects the aluminum parts from galvanic
corrosion, too.
Thus we advise to put a thin layer of Antal Hydrolub Grease; not only to lubricate all
moving parts, but also to protect the aluminum surfaces in contact with s.steel parts,
e.g. screws.
Kit Winch. Antal provides a repair kit winch containing pawls and springs (Mod. Kit
Winch).
The complete maintenance includes the opening of the winch, the cleaning of the p
parts from old lubricants and the new lubrication of all moving parts.

MAINTENANCE SEQUENCE
Perform the following operations on a
work bench
Remove the two half rings at the top
of the center rod.
Unscrew the 4 screws on the base
and lift the base-stem block.
Clean the old lubricant from the roller
bearings; check the well-being of the
stem where the bearings slide; clean
the screw-holes on the base, the
screws and the washers.
(When re-mounting, it will be
necessary to put new grease on all
these parts, including the screws’
threads.
The Antal Hydrolub Grease also
serves the function of protection of
the aluminum from the risk of galvanic
corrosion.)
Now, simply remove the center rod.
Clean the old lubricant from all parts.
Lift the roller bearings, the spacers (in
case of presence) and the washers.
Carefully clean all these parts with a
soft bristle brush and solvent.
The cleaning of the gear section
and of the gears at the base of the
center rod does not require further
dismanteling.
It will be enough to use a soft bristle
brush and solvent.

Maintenance of Self tailing winch
In case of complete inspection or
of the substitution of parts, it is
necessary to lift the self-tailing disks
to check the good state of the springs,
spacers and pawls.
For the dismantling of the gear
section at the bottom of the center
rod, proceed by removing parts of the
exploded view drawing.
Furthermore, open the gear section.
The steel axels are isolated from the
aluminum parts of the winch thanks to
resin insulating gaskets shaped like
a hat.
44
The bronze gears, the pawls and
the springs compose a system that
transmit motion in a specific way.
While re-mounting the gear section,
pay attention to the correct positioning
of the outer gear according to the
pawls direction.
