INSPECTION
Installation and Inspection of Torque Converter

●

After inserting the torque converter to the transmission, check
dimension "A" to ensure it is within the reference value limit.

INSTALLATION

Installation is in the reverse order of the removal.

CAUTION:

●

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 driv-
etrain components.

●

Do not reuse O-rings and copper washers. Refer to 

AT-240, "COMPONENTS"

 .

●

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 tightening the bolts for the torque converter while securing the crankshaft pulley bolt, be
sure to confirm the tightening torque of the crankshaft pulley bolt. Refer to 

EM-55, "TIMING

CHAIN"

 .

●

When installing transmission to the engine, tighten the bolts to
the specified torque using sequence shown.

●

When installing the drive plate to torque converter bolts, align
the positions of bolts for drive plate with those of the torque con-
verter and temporarily tighten the bolts. Then tighten the bolts
with the specified torque.

●

After completing installation, fill A/T with fluid and check fluid
leakage, fluid level, and the positions of A/T. Refer to 

AT-12, "A/

T FLUID"

 , 

AT-216, "Checking of A/T Position"

  and 

AT-216,

"Adjustment of A/T Position"
