WARNING! Cylinders are capable of exerting
very high loads and can break associated
components. Inspect all standing backstay
and forestay rigging components to ensure
they are in good condition. Failure to inspect
components may result in sudden breakage
at high loads.

Installation

Installation

Review all instructions carefully prior to installation of your
new Integral Hydraulic Cylinder.

1. Carefully unpack the cylinder and check for visible
defects. If any signs of damage are present, contact
your dealer at point of purchase or Harken.

2. Extend cylinder to prepare for installation.

Turn release knob counterclockwise completely.

Attach the bottom (end) clevis to the deck, and attach
the upper (rod) clevis to the main halyard. Pull rod
clevis as necessary to fully extend the cylinder.
When cylinder is extended, detach from deck
and main halyard.

3. Check installation site for clearance.
Attach a standard eye/jaw toggle to the cylinder’s
bottom clevis before securing to the chainplate.

• Install two pins in different orientation to accommodate
stay movement so the aluminum won’t fatigue during use.

• Standard toggles fit all Harken cylinders.

NOTICE: Be sure to include toggle length in cylinder

length for deduction from stay.

4. Mount cylinder rod end up.
When mounting, orient pump handle to your preference.

Installation

5. Check to see if gauge is aligned to your preference. If
necessary, you may loosen set screws on bottom of
cylinder tube (above release knob) completely. Rotate
cylinder tube to adjust gauge to 1 of 4 positions as
noted in diagram.

6. When gauge is in preferred position, re-tighten set
screws. Make sure screws install into pump housing
dimples.

CAUTION! Limit cylinder rotation to avoid
problems or damage.

7. Attach cylinder to backstay.

• Use 3 mm hex driver to remove screw from clevis
pins.

• Attach lower clevis to toggle/chainplate. Open the
release valve and extend the cylinder.

• Attach upper clevis to backstay.

8. Use Blue 242 Loctite

when installing screws to

prevent loosening.

Bleed Pump

All Harken Integral Hydraulic Cylinders are cycled and
tested at factory prior to shipment. However, oil can
become displaced inside cylinder during shipment or
storage. Bleed pump prior to use.

1. With cylinder in vertical position, rod end up, fully

extend the cylinder.

2. Open release valve and pump for one (1) minute.

When complete, the pump and cylinder are bled.

Operation

The Harken Integral Hydraulic Cylinder is easy to use and offers unique, double-acting pump action to move oil twice as
fast as a single-acting pump. Follow these simple steps for cylinder operation.

Increase tension

1. Turn pressure release knob clockwise to close.
The resting position for the pressure release knob is
closed.

2. Move pump handle in and out until desired tension is

achieved.
Notice: It is impossible to over-tighten the knob or
damage the valve by hand.

Decrease tension

1. Turn release knob counterclockwise to open. Release
speed depends on how far the knob is turned.

WARNING! Backstay cylinders can overload
jib halyard and jib luff components including
furlers. Be sure to check and/or ease jib
halyard before tensioning backstay.

Relief Valve Settings

The Integral Hydraulic Cylinder relief valve is preset at
our factory to limit the tension to the maximum load of
the recommended cable of the rigging for which it is
used. Each cylinder is set to provide a specific
maximum pull force.

Reading Cylinder Gauge

The easy-to-read analog gauge
displays oil pressure in thousands
of pounds per square inch. Refer
to the table below to convert oil
pressure to pull force.

Notice: Gauge needle may go beyond specified relief setting
during pump action then return to the maximum specified
relief setting. This is normal and is part of the cylinder design.

Cylinder tension can be increased by adjusting the pressure
relief setting. Contact your Harken Service Representative
for assistance.

Inspection

Perform a visual inspection of the Integral Hydraulic Cylinder prior to each use to ensure clean, unobstructed
working conditions.

Care and Maintenance

Harken cylinders should give years of reliable service. If cylinder is properly bled, and clean environment is
maintained, no regular maintenance is required. Seals should be changed every ten years (dependent on use)
unless cylinder eases without pressure relief valve releasing the pressure first. If you experience any problems
with your Harken Integral Hydraulic Cylinder, contact your Harken Service Representative.

Warranty

Harken warrants that each Harken product, when properly used and maintained, will be free from defects in
material and workmanship from the date of receipt of the product by the final customer. Harken products are
covered by two different kinds of warranties, on the basis of the purchaser and use made of them.
