GENERAL

SINGLE REDUCTION ANCHOR WINCH

INSTRUCTIONS

A. General Description

The J.K. Fabrication Single Reduction Anchor Winch is constructed to

provide many years of reliable service, being built with the finest Marine Grade

Materials and utilizing the proven RE Series of hydraulic motors from White

Hydraulics. The Winch is designed to haul (or pay-out) rope (or cable) by the

rotation of the hydraulic powered drum. It is important that the Anchor Winch

be mounted “in-line” with the vessel Bow Roller, so that the incoming rope (or

cable) spools onto the winch drum as evenly as possible.

Your new J.K. Fabrication Single Reduction Anchor Winch may or may not

be equipped with the Optional Winch Brake manually operated by a Handbrake

Wheel.

Contact J.K. Fabrication for recommendations and circuit diagrams before

adding an Anchor Winch to your hydraulic system.

CAUTION

AS WITH ANY WINCH OR HOIST, EXTREME CARE MUST

BE FOLLOWED TO PREVENT INJURY WHILE IN USE. DO

NOT OPERATE THE J.K. FABRICATION ANCHOR WINCH

IN AN UNSAFE MANNER AT ANY TIME.

B. Anchor Winch Installation

The J.K. Fabrication Anchor Winch must be securely mounted to a rigid

surface, which will not flex when the winch is in use. The winch should be

mounted with the centerline of the drum in a horizontal position. Also consider

the strength of the deck the winch will be installed onto, along with any needed

winch foundation, which may be necessary to strengthen (and/or to secure) the

winch to the deck, along with the location of the hydraulic hose connections.

In determining the Anchor Winch hauling location, you should consider that the

J.K. Fabrication Anchor Winch will spool the rope (or cable) onto the drum

more evenly if the winch is mounted farther from the bow roller. The closer the

winch is to the roller, the more un-even the rope (or cable) will spool onto the

drum, as the fleet angle is greater.

Secure the winch to your deck using best practice. Remember, you may not

have to anchor very often, but when you do, you’ll want the anchor winch to

hold, and not fail. If you have any doubt, consult your naval architect. Note:

Large holes are provided in the winch housing to aid in mounting. Use Bolts of

adequate Size and Strength to mount the Anchor Winch keeping in mind the

intended load on the winch.

The J.K. Fabrication Anchor Winch is Pre-plumbed with a Directional Control

Valve for easy installation (see Fig. 1 below for Typical Connection of

Hydraulic Lines to Winch Control Valve).

C. General Anchor Winch Operation

As the J.K. Fabrication Anchor Winch is equipped with a Push-Pull operated

Valve Spool having four positions, moving the valve control handle will cause

the winch to:

1) Haul-in

2) Center or neutral (Hold Position)

3) Pay-out

4) Float-position or free-wheel

Figure 2- Control Valve Handle Positions

NOTE: The J.K. Fabrication Anchor Winch Directional Control Valve is

equipped with a Relief Valve ‘Factory-Set to 1500 PSI.’ Adjustment of this

valve is possible should customer desire to change. Please consult J.K.

Fabrication for instructions prior to adjusting.

NOTE: Even though the Directional Control Handle is designed to be re-

positional, NEVER re-position the handle while the Hydraulic Power is on, as

loss of winch control could be the result!

Haul-In Position

Center-Stop-Hold Position

Pay-Out Position

Free-Spool Position

NOTE: Spool Cable onto the Drum in Overwound direction, and always have

AT LEAST TWO LAYERS of Cable on the Drum UNUSED during payout.

The J.K. Fabrication Anchor Winch is equipped with a locking Dog to firmly

lock the drum while anchored. NOTE: Wire Cable must be spooled

‘Overwound’ onto the Drum for the Dog to work properly.

Drum Dog Operation: Upon completion of Pay-out of Anchor and Cable,

Loosen Dog Wing Nut, Rotate Dog Clip towards the Anchor allowing the dog

arm (pawl) to engage the drum ratchet. (See Fig. 3 and Fig.4)

NOTE: Always have the Drum Dog ‘ENGAGED’ while anchored, AND

while hauling in your Cable and Anchor!

NOTE!

DO NOT Engage ‘Locking Dog’ while Anchor Winch is Free-spooling Out

or Powering Out!

RB Series Anchor Winch Operation:

As stated above, the Anchor Winch is controlled with the supplied 4-position Bi-

directional hydraulic control valve. The 4 positions include, power-in, power-out,

neutral, and a Detented (Float) position. The Information which follows covers the

operation of all 18”, 20”, 24”, 26”, 28”, and 32” Single reduction Anchor Winches

that are equipped the optional, manual Handbrake Wheels.

Follow the steps in the order below to operate the Winch:

1- When deploying the anchor, power the drum out until the anchor is free

from the bow. Stop the winch drum by slowly releasing the valve handle to

its neutral (or spring-centered) position. With the handle in this position, the

drum will stop.

2- Rotate the Handbrake Wheel in a Clockwise Direction until it becomes

‘Snug’, tightening the Band Brake to the Brake Drum.

Dog Clip

3- Shift the Hydraulic Control Valve Handle to its full travel (Detented)

position. The user will note that the valve handle will hold itself in this

Detented (Drum Free-spool) position.

4- Slowly begin to release the brake by rotating the Handbrake Wheel in a

Counter-Clockwise Direction. Deployment speeds of 80 to 140 Feet per

Minute are normal.

NOTE!

It’s very important to leave some tension on the Brake Band as the Anchor is

being deployed. Do not release the Handbrake Wheel completely during

deployment. When the Anchor reaches the ocean floor or seabed, the drum

could over-rotate (due to the inertia of the rotating drum) causing the cable to

turn into a ‘Bird’s Nest’, if some tension is not left on the Band Brake.

NOTE!

Never use the Hydraulic Control Valve or Shift the Valve Handle from its

‘Float-position’ to slow down or to stop the winch drum during anchor

deployment. Use ONLY the Handbrake Wheel to slow and stop the anchor

during deployment.

5- Once the Anchor is safely on the ocean floor or seabed, turn the Handbrake

Wheel in a Counter-Clockwise Direction to further release the Band Brake

completely. When the Handbrake Wheel is rotated Counter-Clockwise

completely, the user will notice the Brake Handwheel will come up against a

‘stop’. Come-up easy against this ‘Stop’… Don’t apply high torque after the

stop is reached.

NOTE!

Failure to completely release the Handbrake Wheel after the anchor reaches

bottom will prematurely wear out the Brake Band, and cause the Hydraulic

Motor to work harder. If maximum anchor weight is used, it can also cause

the Drive Chain and Sprockets to wear faster than normal.

6- The operator may now pay-out cable and chain until the desired ‘scope’ is

achieved.

NOTE!

NEVER SPOOL OFF THE LAST TWO LAYERS of rode on the drum core!

7- Now loosen the Dog Clip by turning the wing nut in a Counter-Clockwise

Direction. Move the Dog Clip forward allowing the Dog Arm to engage the

Dog Ring.

NOTE!

Always use the Dog System. Failure to use the Dog System will break and

damage the Drive Side Components. Never engage the Dog System during

anchor deployment (or when the drum is being rotated in a Free-spool or

power-out direction). Keep the Dog System engaged during all anchoring, as

well as when bringing up the anchor, especially as the anchor approaches the

Bow Roller. Once the Anchor reaches the waterline, see the Very Important

Note that follows to ensure that the Anchor may be deployed easily the next

time.

VERY IMPORTANT NOTE!

As the anchor is hauling-in and reaches the waterline, bring the winch to a

stop by slowly releasing the valve handle to its Spring-loaded Center Position.

At this point, the user must DIS-ENGAGE THE DOG into Position A

(allowing the drum to rotate freely). The user may now bring up the anchor

and snug to the Bow Roller. NEVER leave the Dog engaged to the Drum

when the anchor is snug to the Bow Roller, as the Dog Arm could jam tight,

thereby not allowing anchor deployment on the next set.

D. Wire Cable Installation

All J.K. Fabrication Anchor Winches are designed to ‘Over-Spool’: that is, the

cable or line must be led onto the drum above the Core Barrel. This orientation

allows the Drum Dog Pawl to work properly.

Located on the Drum Core Barrel is the Cable Hold Tube. This Tube is welded

securely to the Core Barrel internal structures, and is fitted with set screws.

When spooling onto the drum, the cable is held fast by this tube and the

tightened set screws. The Sole purpose of this arrangement is to allow the

initial spooling of the cable onto the drum.

NOTE: THE CABLE HOLD TUBE AND SET SCREWS ARE NOT DESIGNED TO

WITHSTAND ANY LOADS GENERATED DURING THE USE OF THE WINCH.

J.K. Fabrication strongly recommends a minimum wire capacity of Two

Layer’s deep on all J.K. Fabrication Winches during operation. This

means that the 1st and 2

nd layers of wire in direct contact with the Core

Barrel must never be wound or unwound when the winch is under loaded

conditions. This condition insures secure handling of the intended loads,

along with safe operation of the winch.

ALL WINCH OPERATORS MUST BE NOTIFIED AND AWARE OF

THE ABOVE RECOMMENDATION!

E. Hydraulics

The J.K. Fabrication Single Reduction Anchor Winch requires a vessel

hydraulic system delivering 16 to 20 Gallons Per Minute (GPM), along with a

corresponding hydraulic system operating pressure of 2000 to 3000 Pounds Per

Square Inch (PSI) (3000 PSI Maximum), for normal winch operation. See the

first page (Title Page) of this Manual for Hydraulic Oil Flow and Pressure

Recommendations for your particular Winch.

(See the Typical Hydraulic Circuit Drawing following the General Instructions

for Hydraulic Circuit Recommendations)

NOTE: The J.K. Fabrication Single Reduction Anchor Winch is designed to

develop very high (and potentially dangerous) line pull torque. Consult with

J.K. Fabrication or a licensed Hydraulic Company to ensure proper Hydraulic

Connections, Hydraulic Line Sizes, Hydraulic Flows and Hydraulic Pressures.

F. Maintenance

There is one provided grease fitting (which lubricates the outermost drum

bearing) on the J.K. Fabrication Anchor Winch. It is recommended that

during heavy anchor winch operations this Zerk Fitting be greased on a weekly

basis with Multi-purpose grease.

SERVICE INSTRUCTIONS FOR THE RE [500 & 501] SERIES MOTORS

PI444002 Rev. 12.06

For Use With Seal Kits: 500444001 & 500444002

dimensions: mm [in]

NOTE: IN DECEMBER 2006, THE 500 SERIES INCORPORATED A DESIGN CHANGE. THIS SET OF INSTRUCTIONS WILL AID IN THE DISASSEMBLY AND ASSEMBLY FOR BOTH DESIGNS. PLEASE REFER TO THE EXPLODED VIEW DRAWING TO DETERMINE WHICH DESIGN IS BEING REPAIRED AND THEN FOLLOW THE APPROPRIATE INSTRUCTIONS FOR THAT DESIGN.

Motor Section Disassembly (Same Instructions For Both Designs)Remove all shaft related components from shaft (27) (i.e. keys, wire rings, nuts). To aid in reassembly of the motor, make a "V" shaped set of lines from the endcover (24) to the housing using either paint or a marker. With shaft facing down, secure motor in vise by clamping on to housing (15).

Loosen and remove seven bolts (26) holding motor assembly together. Remove endcover (24) and endcover seal (10). Discard seal. Remove balance plate (22) taking care not to drop the three steel balls (23) located in the three holes in the balance plate (22). Remove rotor assembly (21), manifold (19), drive link spacer (20) (NOTE: Some motors do not use spacer), drive link (18) and thrust bearing (17). Remove body seals (9) from rotor assembly (21) and housing seal (8) from housing (15) and discard seals. (NOTE: Compare old housing seal (8) to the two housing seals included in kit to determine which one to use.) Gently tap shaft (27) upward from housing (15) and remove through rear of housing and lay aside.

Housing/Shaft Disassembly And Assembly (Design That Utilizes A Seal Carrier (11))Remove housing (15) from vise and turn over. Pry dust seal (1) from housing. Push the seal carrier (11), thrust washer (12) and thrust bearing (13) down until they make contact with the roller bearing (14) located in the housing bore.

Remove wire ring (2), steel backup shim (3) and high pressure seal (4) from inner bore groove with a small screwdriver. Lift seal carrier (11), thrust washer (12) and thrust bearing (13) from the housing bore. Using a small screwdriver, carefully pry shaft seal (7), backup seal (6), and metal backup shim (5) from seal carrier (11) and discard. Lay seal carrier (11), thrust washer (12) and thrust bearing (13) aside. (NOTE: If a new thrust washer (12) and seal carrier (11) is included in kit, old items may be discarded).

At this point, all parts should be cleaned in an oil-base solvent and dried using compressed air (For safety, observe all OSHA safety guidelines). All new seals should be lightly coated in clean oil prior to installation.

Place shaft (27) on a clean flat surface with output end facing up. Place thrust bearing (13) (NOTE: If thrust bearing has integral washer, make sure washer surface faces down.) Then thrust washer (12) on shaft (See Technical Bulletin PI444004 to determine correct thrust washer to use). Lightly coat seal area of shaft with clean oil and place plastic installation sleeve with shaft seal (7) down onto shaft covering all splines, keyways and wire ring grooves. Slide shaft seal (7) down onto shaft (27) making sure that lip on seal faces down (See Figure 1 for correct seal orientation) until it contacts thrust washer (12). Remove plastic installation sleeve. Carefully install the backup seal (6) onto the shaft (27) with the flat side up and the seal lip facing the shaft seal (7). Place the metal backup shim (5) onto the shaft and against the backup seal (6). Place the seal carrier (11) onto the shaft (large end down) and carefully press the seal carrier (11) down onto the seal assembly using an arbor press and sleeve to compress the seal into the carrier.

With pilot side facing up, place housing (15) on spacers to raise housing approximately 6 [.25] above work surface (NOTE: Spac-ers should allow shaft to contact work surface). Place shaft/seal carrier assembly into housing (15). Install high pressure seal (4) into groove in housing. Install metal backup shim (3) against high pressure seal (4) in groove in housing bore by squeezing the shim (3) between thumb and forefinger to bow shim. While maintaining bow in shim, start the shim into the groove and use a small screwdriver to push the shim into groove. Install wire ring (2) into the groove making sure that the ends are butted.

While holding shaft into housing, place housing/shaft assembly in vise with shaft end down. Making sure that end of drive link (18) with crowned splines goes into shaft end, install drive link (18) into shaft and tap lightly to seat the seal carrier against the wire ring (2). Place thrust bearing (17) over drive link (18). If seal carrier (11) is properly seated against wire ring (2), thrust bearing (17) will be flush with rear surface of housing.

Housing/Shaft Disassembly And Assembly (Design That Does NOT Utilizes A Seal Carrier (11))Position the housing (15) in vise and use a slide and hammer type bearing puller to remove the rear housing bearing (16), the bearing spacer (32), and the front housing bearing (14). Remove the thrust washer (12) and thrust bearing (13) and set aside. Us-ing a small screwdriver carefully pry the shaft seal (7), backup seal (6) and metal shim (5) from housing bore and discard.

Remove the housing from vise and turn over and pry the dust seal (1) from housing and discard.

At this point, all parts should be cleaned in an oil-base solvent and dried using compressed air (For safety, observe all OSHA safety guidelines). All new seals should be lightly coated in clean oil prior to installation.

Place housing (15) in vice with the seven bolt assembly holes facing up. Place metal shim (5) in the smallest diameter recess in

Install thrust washer (12) into housing and using an arbor press, seat the shaft seal (7) into housing (15), then place the thrust bearing (13) into housing.

Place front housing bearing (14) onto housing and press bearing into housing to a depth of 60,1 [2.37] from the rear surface of the housing (15) to the top of the bearing. Insert the bearing spacer (32) into the housing. Place the rear housing bearing (16) onto the rear housing bore and press to a depth of 3,6 [.14] from the rear surface of the housing (15) to the top of the bearing (16). Place the shaft (27) down into housing (15) and place thrust bearing (17) on top of shaft (27). If shaft seals are properly seated against the housing (15), thrust bearing (17) will be flush with rear surface of housing.

Motor Section Assembly (Same Instructions For Both Designs)Install housing seal (8) into groove in housing (15). Place manifold (19) onto housing, (15) side with only seven holes facing housing (15). Place body seals (9) in grooves in both sides of rotor (21). Place rotor (21) onto manifold (19) with side of rotor with chamfer in splines facing manifold (19).

Install balance plate (22) onto rotor (21) making sure holes for steel balls (23) faces up. Install three steel balls (23) in holes in bal-ance plate (22). Install endcover seal (10) into groove in endcover (24) and place endcover onto balance plate (22). Install seven assembly bolts (26) and pre-torque to 13,6 Nm [10 ft. lbs.] Using the bolt torque sequence shown in Figure 3, final torque all bolts to 67,8 Nm [50 ft. lbs.]

Remove motor from vise and place on work surface with shaft (27) facing up. Making sure that lip on seal (1) faces up, place dust seal (1) over shaft (27). Using a sleeve and a hammer, carefully drive dust seal (1) into place.

Installation and maintenance

The SD11 valve is assembled and tested as per the technical specification of this catalogue.

Before the final installation on your equipment, follow the below recommendations:

-- the valve can be assembled in any position, in order to prevent body deformation and spool sticking mount the product on a flat

surface;

-- in order to prevent the possibility of water entering the lever box and spool control kit, do not use high pressure wash down directly

on the valve;

-- prior to painting, ensure plastic port plugs are tightly in place.

NOTE -- These torque are recommended. Assembly tightening torque depends on many factors, including lubrication, coating andsurface finish. The manufacturer shall be consulted.
