Cutting Track to Length Using Fastener Hole for Securing End Control

R27 tracks have holes drilled for E27 series stop and end controls
/32" (15 mm)
if entire length is used. If you shorten one end, make cut so end
control screw passes through a track fastening hole. It is best to
have track cut with an electric cross cut saw at a machine shop.
Low beam track may be cut using a hacksaw but it is difficult to
get a straight, even cut. Measure from center of hole to end of
track so hole center is
not work, make sure that end control screw hole does not interfere with mounting or pinstop hole. Note: Since trim caps are not
used with E32 or E27 end controls, do not leave room for them.

Installing Loader Track for Cockpit Installations
Track mounted in cockpit can make it impossible to remove
car without removing the entire track. Plan ahead to avoid
this problem. Cut a "loader track" section under one end
control. Loader track length must be long enough to slide
car off end. Measure track from finished end so that the 2nd
track fastener hole becomes the end control mounting hole

Curved Track Limitations
Cars will not roll on curved track if the radius is under the minimum listed below. A shorter car can roll on
a smaller radius. Refer to the chart below and make sure the radius is equal to or greater than the radius
listed for the car. To find the radius go to www.harken.com.

Mid-boom
End-boom
Harken high beam track is designed for unsupported
spans in cockpits and companionways with additional
bridge structures.
The length of span depends on the load on the car. The
higher the car load the less span the track can handle.
If the car is sized correctly, car length determines the
spanning capability. Longer, high-load (HL) cars require shorter spans
because the loads are so much greater. See track spanning chart.
Track is shipped with 8 bolt slides and stainless washers or 10 when

track is longer than 7' (2 m). Contact Harken if more slides or washers are required. Part numbers. Slides HCP341. Stainless Washers

Fasteners
Carefully choose fasteners that are made from A4 (316) or A2 (18-8) stainless steel. Make sure to use large
washers or backing plates and lock washers or locknuts. It is installer's responsibility to choose correct screws,
nuts, washers, and threaded plates, taking account materials and loads they will have to bear. Harken assumes
no responsibility for incorrect installation of track or for an incorrect choice of mounting fasteners.
WARNING! Use correct number and type of fasteners in A4 (316) or A2 (18-8) stainless steel.
Fasteners made of other materials may not have sufficient strength or may corrode which
can result in track pulling off deck suddenly and unexpectedly during high loads.
Deck Strength
Install traveler track on a flat area of the deck that is capable of bearing a load equal at least twice the maximum working load of the traveler car to be used. Reinforce deck if necessary. It is installer’s responsibility
to carry out all structural tests needed to ensure that the deck can bear the load. If in doubt about the correct track position and deck strength, consult the yard that built the boat. Harken assumes no responsibility
for incorrect installation of track, or for incorrect choice of mounting screws.
WARNING! Failure to ensure the correct deck strength can result in the track pulling off the
deck suddenly and unexpectedly during high loads.

Mounting Low-Beam Track
Carefully choose mounting screws by consulting charts and warnings above. R27 track requires
8 mm flathead stainless steel screws (see "Fasteners" above). Retrofit 1602 and 1605 track requires
5
/16" or
1
/4"
(6 mm) flathead screws. Be sure which track you have.
Carefully drill holes and apply high quality sealant. Through-bolt track using all fastener holes. Secure
under the deck using large washers or backing plate and washers and locknuts.
Low-beam track must not be used for spanning.
Mounting High-Beam Track on Unsupported Spans
Place at least three (3) bolts at each end of the track, with two (2) bolts placed immediately next to each
inboard end of the span. For the remainder of the supported beam, place bolts on 4" (102 mm) centers.
Stainless Steel
Washer
1849 Track Riser
Use backing plate or stainless
steel washer behind each nut
To mount track, calculate hole spacing and drill desired
holes in deck, seats or other mounting surface. Place
appropriate number of
1
/4" (6 mm) hexhead bolts on
bolt slides and slip into groove in bottom of track.
Use H-8557A metric spacers with 6mm bolts.
Place one stainless steel washer (included) on each bolt under track.
These washers force sealant into mounting holes to insure a good seal.
Apply high quality sealant to mounting surface around each hole. Place bolts
into holes and lower track. Bolt securely using lock washers or lock nuts. Most
mounting surfaces will require a backing plate for proper strength.
Low-beam track must not be used for spanning.
WARNING! Using track not intended for spanning or failure to follow spanning recommendations may result in track pulling off deck suddenly and unexpectedly during high loads.
Inspect
Carefully inspect track and mounting hardware for any signs of loosening, cracks or damage. Inspect end stops to
make sure they are secure and that there are no cracks or damage. Arrange control tackle so cars do not hit end stops
under load.
WARNING! Failure to inspect tracks and stops can result in track pulling off deck
suddenly and unexpectedly during high load.
Maintenance
Traveler Cars: Clean by frequently flushing with fresh water. Periodically clean car by squirting a detergent/
water solution into center openings. Roll car back and forth to distribute evenly then flush bearings with
fresh water.
Do not use spray lubricants because ball bearings may skid not roll. Apply a few drops of McLube
™
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 a light machine oil. Too much oil attracts dirt.
Track: Clean with detergent and water.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part
and is not covered under the Harken warranty.
