INSPECTION
Installation and Inspection of Torque Converter

After inserting a torque converter to a A/T, be sure to check dis-
tance “A” to ensure it is within the reference value limit.
INSTALLATION
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing A/T assembly to the engine assembly, attach the
fixing bolts in accordance with the following standard.
–: Engine to transmission
–: Transmission to engine

Align the positions of tightening 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.

When tightening the tightening bolts for torque converter
after fixing crankshaft pulley bolts, be sure to confirm the
tightening torque of crankshaft pulley mounting bolts.
Refer to EM-53, "
TIMING CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that
transmission rotates freely without binding.

Install crankshaft position sensor (POS). Refer to EM-26, "Removal and Installation" .
