Periodic Maintenance and Adjustment

Routine care of your ROKON vehicle is easily done and is important for rider safety and vehicle longevity.

  1. Inspect all fasteners for tightness.
  2. The drive chains require adjustment at intervals, depending on the mileage and the care which the operator has given the chains. Initial wear must be taken up by adjustment after the first few hours of use. Total deflection should be 1/2” to 3/4” when measured midway between the two sprockets of the most loose position. To adjust the chains, loosen the axle bolts and the adjusting bolt lock nuts, and turn the adjusting bolts equally in or out as required to give the chain the proper setting. After adjusting the chain, rotate the wheel and check to make sure the chain is aligned properly. Periodically, the chains should be removed from the machine and cleaned in solvent and re-lubricated. They should be lubricated with one of the chain lubricants on the market which can be applied to the chain in a liquid form and will penetrate to the inner parts of the rollers.
  3. Clean the air filter based on use. See Engine Manual.
  4. Use normal repair procedures for tires and tubes. Re-seat the tire beads with 40 PSI , then deflate to the 3 -5 PSI operating pressure.
  5. The miter box and transmission should not require service other than checking the oil level or replacing oil seals. The miter box should be removed and oil changed yearly. The miter box is assembled with special tooling to determine the correct tooth engagement and backlash. It is not advisable to attempt to dismantle the unit, unless necessary. The transmission should be drained and refi lled on the same yearly schedule. There is a drain plug on the bottom of the transmission, a fill level plug partway up, and a fi ll plug on the top. The miter box takes 2.5 fluid oz. of EP 80W90 gear lube oil. The transmission takes 6 fluid oz. of EP 80W90 gear lube oil.
  6. Check belt for wear. Belts last at least a year and generally average 4-5 years.
  7. Check the throttle for full return and feel.
