Considerations for
Determining Track Length.
Note: Track is longer than sail luff length.
1. Upper end: Extend track 203 mm (8") above
headboard halyard attachment point to allow for
sail stretch as main ages. Track must not block
mast halyard exit.
2. Lower end: Place 152 mm (6") Screwpin
Endstop track on mast. Make sure car clears
gooseneck fittings and adjust height as
necessary. Measure to lower end of track.

2. Drill track hole, holding drill perpendicular to mast face. Tap threads and install
screws using blue Loctite®.
3. Align track at joints. Use 2711 splice links and round rods or dowels on
outside of track to align during installation. Hold in place with spring or “C”
clamps until track is secured.
Load all cars before installing bottom track and endstop.

IMPORTANT! Keep balls captive by loading cars onto track without sail installed. Car must have 20 balls per side.
Consult chart for correct type of balls.
DO NOT MIX CARS. High-load brown Torlon®balls are used in headboard and batten cars. Luff cars use low-load black Delrin®balls.
2. Load Intermediate car (if used). Alternate with batten cars until all cars are loaded.
Mast up: Use halyard to hold cars up.
1. Headboard cars: Hold car so cap screw head faces up. Align car on guide section of
loader track and gently roll onto upper tracks. If car sticks, realign and roll onto track.
Tip: To load headboard car assembly, angle headboard coupler, roll car onto track.
If necessary, remove headboard assembly.
3. Install Screwpin stop.

Car Maintenance/Cleaning
Clean beginning of season, or if cars bind.
Squirt detergent and water into ball bearings. Circulate by moving cars up and down.
Let stand. To remove detergent, spray water into ball bearings and circulate. Clean
tracks with detergent and water.
Use OneDrop™Ball Conditioner
Once dry, use only a single drop of McLube®OneDrop™ ball bearing conditioner.
Do not use spray lubricants because ball bearings may skid not roll. Apply one to
two drops of McLube®OneDrop™ to ball contact surfaces of track. Roll car back
and forth through OneDrop™ several times to distribute onto bearings. Wipe
remaining OneDrop™ off track. OneDrop™ is preferred but you can also use
one to two drops of alight machine oil. Too much attracts dirt.
Inspect
Inspect Battcars for loose locknuts. Replace. Inspect batten receptacles for
loose screws.
Removing Sail
From Cars: Remove clevis pin from head of sail. Use a 4 mm hex wrench
and a 8 mm wrench or nut driver on other cars.
Cars and Sail: Keep cars lined up with track when sliding off.
Inspect Cars: 20 balls per side. Replace 5 mm locknut after two removals.

Lazy Jacks
Use shock cord to hold lazy jacks open so
battcars and battens will not catch on them
when hoisting sail. This will also help stop
slapping of lazy jacks on sail. Attach one end
to lower spreader tips and the other to lazy
jacks. Make sure shock cord is long enough
so boom can swing out all the way
without damaging spreaders.
Operating Precautions
When lowering sail, do not let halyard go.
Ease cars down by keeping a wrap on winch.
On boats with unstayed masts, vang must
be used to prevent over rotation of upper
part of sail. Over rotation can damage
batten receptacles.

Installing 3813 Headboard Coupler Car Assembly
3813 headboard coupler attaches to standard headboards—some headboard modification required.
Maximum thickness of headboard plates and sail: 9/16" (14 mm)
Halyard Attachment Hole
Use aft hole if headboard has two.
If not, drill second hole to accept halyard
shackle pin. Locate hole approximately
63.5 mm (2 1/2") aft of existing hole.
Coupler Attachment Hole
Drill 11 mm (7/16") coupler attachment hole so
center is 101 mm (4") from top of headboard
and 25 mm (1") from front edge of boltrope.
Leave at least 9 mm between front of headboard
plate and front edge of coupler attachment hole.

Distance Between Attachment Points
Battens and intermediate cars placed at sailmaker's discretion.
Maximum distance between attachment points is 1.2 m to
1.35 m (4' to 4'6").
Distance may be slightly greater. Contact Harken to discuss
sail reshaping to eliminate luff flutter.
Note: Adding battens may reduce stack height by eliminating
luff cars.
Setting Reef Points
Space reef points halfway between sail attachment points.
Battens or reef points may need to be moved—Diagram A.
Note Batten fittings and cars cannot handle reefing outhaul or
downhaul loads. Transfer loads to tack fitting—Diagram B.

General Maintenance (see specific maintenance on page 16)
Harken equipment is designed for minimal maintenance, but some maintenance is required for optimum and safest possible operation
and to comply with the Harken limited warranty. In general, the most important aspect of maintenance is to keep your equipment clean
by frequently flushing with fresh water.
In corrosive atmospheres, stainless parts may show discoloration around holes, rivets and screws. This is not serious and may be
removed with a fine abrasive.
With the exception of winches, do not use grease unless specifically recommended in the instruction sheet.
Flush blocks thoroughly with fresh water. Periodically disassemble blocks, if possible, and flush with detergent and fresh water.
Lubrication is not required.
Important! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part and is not covered under
the Harken warranty.
Warranty
For additional safety, maintenance and warranty information see www.harken.com/manuals or the Harken®catalog.
CB System (Slug Mount/Drill & Tap) Operation Troubleshooting
Problem Probable Cause Solution
Cars bind. Balls missing from car. Remove cars, load balls and slide cars back on track.
Dirt in cars. Use detergent and fresh water to flush dirt out of cars;
move cars up/down do circulate; follow with high
pressure water; clean track grooves.
Nut on Battcar is not holding. Locknut has been used too many times. Get new 5 mm locknut.
Batten receptacle does not rotate. Nuts are too tight. Loosen nuts slightly.
Cars jam when raising sail. Headboard or cars are catching on lazy jacks. Use topping lift or rod vang and shock cord to pull
lazy jacks out to shrouds.
Sail will not go all the way up. Sail is too tall or sheave is too far forward. Have sail shortened or move sheave aft.
Vertical post or pin on batten receptacle bending. Reef loads are being transferred to batten
receptacle.
Transfer reef downhaul and outhaul loads to mast
or boom gooseneck.
Reef tack fitting will not reach reef hook. Reef point too close to sail attachment. Move intermediate car sail attachment.
CB System (Slug Mount/Drill & Tap) Operation Troubleshooting
Problem Probable Cause Solution
Tracks do not butt up against each other Cut end of top or bottom track is at joint. Make sure the anodized end is towards the
full length track.
Track weight pulling tracks apart. Tracks will come together when you loosen bottom
screw and push the tracks up mast.
Mounting slugs do not fit Slugs wrong size. Different size slug required. Contact your dealer.
Mounting screws will not tighten. Incorrect mounting slug used. Different size slug required. Contact your dealer.
Track will not slide up mast.
Slugs catching on mast splice. Loosen screws slightly. If necessary have someone
at splice area to wiggle the slug past the splice.
Corners of cut track catching. Use file to round off corners of track.
Mast has too much prebend. Ease backstay and/or straighten mast.
Paint or other material clogging mast groove. Clean out groove.
Cars do not fit on track. Track and cars are not the same size. Contact your dealer or Harken.
Balls are missing. Remove cars, load balls and slide cars back on track.
Sail headboard does not fit inside coupler. Ring was not pressed far enough. Take sail to sailmaker.
