CAUTION:


  • B008KAQC01
    *a Heavy object exceeding the capacity of the transmission jack

    Because the continuously variable transaxle assembly is extremely heavy, make sure to follow the work procedures described in the repair manual.

  • If work is not performed according to the procedures described in the repair manual, there is a danger that the transmission jack could drop and components could fall down.


  • B008KL2

    When the engine is hot, do not touch high-temperature areas such as the engine or exhaust pipe.

  • Touching high-temperature areas such as the engine and exhaust pipe could result in burns.

  11. REMOVE ENGINE ASSEMBLY


    1. B008MGFN01

      Remove the 7 bolts and engine assembly from the continuously variable transaxle assembly.

      Note

      To prevent damage to the 2 knock pins, do not pry between the continuously variable transaxle assembly and engine assembly.

      Tech Tips


      • Bolt (A): Remove from continuously variable transaxle assembly side.

      • Bolt (B): Remove from engine assembly side.

  12. REMOVE TORQUE CONVERTER ASSEMBLY


    1. B008MBT

      Remove the torque converter assembly from the continuously variable transaxle assembly.

      Note

      Remove the torque converter assembly from the input shaft horizontally.

  13. REMOVE CVT OIL PUMP TYPE T OIL SEAL

    Note


    • Do not remove the front oil pump assembly from the CVT main body, as there is a possibility of the entry of dust and foreign matter.

    • Clean the work area, the tools to be used, and other equipment, etc. thoroughly before the operation, as there is the possibility that a CVT malfunction, which could prevent the vehicle from being able to be driven, could occur if dust or fine foreign matter enters the CVT.

    • Do not use cotton work gloves, cloths, or paper towels, etc. that may produce lint, dust or foreign matter.

    • Perform the operation as quickly as possible, as dust and foreign matter could enter the CVT while the torque converter assembly is removed.

    • Do not use an air gun until the torque converter assembly has been installed, as it could cause dust and foreign matter to be stirred up.


    1. Clean the tips of both the claws of SST and the center bolt.

      SST
      09308-10010
