INSPECTION
Installation and Inspection of Torque Converter

After inserting a torque converter to a transmission, be sure to
check distance “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 transmission assembly to the engine, attach the fixing bolts in accordance with the follow-
ing standard.

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 the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts.

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-30, "Removal and Installation" , EM-181, "Removal
and Installation" .

After completing installation, check fluid leakage, fluid level, and the positions of A/T. Refer to AT- 1 2 ,
"Changing A/T Fluid" , AT- 2 3 4 , "Checking of A/T Position" , AT- 2 3 4 , "Adjustment of A/T Position" . : 51 N·m (5.2 kg-m, 38 ft-lb)
