  Caution
  • If the clearance between the engine and transaxle exceeds 3 mm {0.1 in}, the oil pump may pull out of the torque converter and the engine may not engage with the transaxle. Therefore, be careful not to exceed the 3 mm {0.1 in} clearance when disconnecting the engine from the transaxle.
  • If the clearance between the engine and transaxle exceeds 3 mm {0.1 in}, the dowel pin may pull out causing damage to the oil pump bushing. Therefore, be careful not to exceed the 3 mm {0.1 in} clearance when disconnecting the engine from the transaxle.
  • If the crankshaft is rotated with the engine disconnected from the transaxle, the oil pump may pull out of the torque converter and the engine may not engage with the transaxle.Therefore, do not rotate the crankshaft with the engine disconnected from the transaxle.
  • If the transaxle is tilted when disconnecting/tightening the engine and transaxle, the oil pump bushing may be damaged. Therefore, maintain the transaxle in a horizontal position when disconnecting/tightening the engine and transaxle.
