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.

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.
