• When replacing an engine or transmission you must make sure any dowels are installed correctly during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings and copper washers. Refer to "COMPONENTS".
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the bolts for th e torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis- tance A.
• Check the fitting of the dowel pins when installing the transaxle assembly and the engine assembly.
