Harken Traveler & Genoa Lead Car Identification

Find the System Size

To find the system size only, measure the top of the track and use the table below.
To identify a specific car, measure the car body width (without control blocks), then use the car length in the identification charts.

System	Car body width	Track width
Micro CB	40 mm 1 9/16"	13 mm 1/2"
Small Boat CB	57 mm 2 1/4"	22 mm 7/8"
Small Boat non-CB	56 mm 2 3/16"	22 mm 7/8"
Midrange CB	70 mm 2 3/4"	27 mm 1 1/16"
Midrange non-CB	70 mm 2 3/4"	27 mm 1 1/16"
Big Boat CB	85 mm 3 3/8"	32 mm 1 1/4"
Big Boat non-CB	84 mm 3 5/16"	32 mm 1 1/4"

CB cars need a track with the groove for the ball-retaining wire; replacement CB cars will not roll on older track. CB+ cars (from 2015) can be converted to run on old non-CB track: remove the corner keepers and retaining clips and load the balls with a car loader. Non-CB track was built before 2003.

Service at Regular Intervals

Service after storage, when cars have too much friction, or when balls seem to slide instead of roll.
Flush with fresh water and detergent, run the cars back and forth to circulate the balls, then high-pressure water.
Clean the track grooves and put a single drop of McLube OneDrop in each ball race. Do NOT use McLube Sailkote – it makes the balls skid.
Inspect: cracked, corroded or elongated shackles (replace at once); loose car screws and cotter pins; loose track and end-control screws (check under deck for stress cracks, especially high-beam track on the cabintop); missing balls; bent CB wire clips.
