INSPECTION

Installation and Inspection of Torque Converter





- After inserting a torque converter to a transmission, be sure to check dimension (A) to ensure it is within the reference value limit.
Dimension (A): 25.0 mm (0.98 in) or more

INSTALLATION

Installation of the remaining components is in the reverse order of the removal, while paying attention to the following.





- When installing transmission to the engine, tighten the bolts to the specified torque using sequence shown.
Transmission bolts: 75 Nm (7.6 kg-m, 55 ft-lb)





- Align the positions of bolts for drive plate with those of the torque converter, and temporarily tighten the bolts. Then, tighten the bolts with the specified torque.

CAUTION:
- When turning crankshaft, turn it clockwise as viewed from the front of the engine.
- After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that transmission rotates freely without binding.
- When replacing an engine or transmission you must make sure the dowels are installed correctly during re-assembly.
- Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive train components.
- Install crankshaft position sensor (POS).
- After completing installation, check fluid leakage, fluid level, and the positions of A/T. Checking, Adjustments.
