12. REMOVE CVT OIL PUMP TYPE T OIL SEAL

CAUTION:

  • Do not remove the front oil pump assembly from the continuously variable transaxle assembly 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 continuously variable transaxle assembly malfunction, which may prevent the vehicle from being driven, may occur if dust or fine foreign matter enters the continuously variable transaxle assembly.
  • Do not use cotton work gloves, cloths, paper towels, etc. that may produce lint, dust or foreign matter.
  • Perform the operation as quickly as possible, as dust and foreign matter may enter the continuously variable transaxle assembly while the torque converter assembly is not attached to it.
  • Do not use an air gun until the torque converter assembly has been installed, as it may cause dust and foreign matter to be stirred up.
