DISASSEMBLY AND REASSEMBLY


caution
  • Only use CVT fluid of the specified brand. Use of CVT fluid other than specified will impair driveability and CVT endurance, and may lead to breakage of CVT.
  • Only use the specified vaseline. Use of vaseline other than specified will impair driveability and CVT endurance, and may lead to breakage of CVT.
  • Disassembly work should be done in a clean dust-proof room.
  • Prior to disassembly, clean any sand or dirt adhered to the outer parts of transmission using steam, white gasoline or another solvent, outside the clean room, so as not to contaminate inner parts of transmission during disassembly or assembly. (Do not allow steam to get inside the transmission, and do not clean rubber parts with gasoline.)
  • After cleaning, remove the torque converter, and drain the CVT fluid.
  • Disassembly and assembly work should be done with bare hands or using plastic gloves.
  • Do not touch inner parts of the transmission after touching its outer parts. (Wash hands after touching the outer parts.)
  • Do not use cotton gloves and rags to prevent from lint; instead, use paper rags.
  • Prior to assembly or disassembly work, make sure conditions are appropriate.
  • Do not re-use the drained CVT fluid.
