INSPECTION
Installation and Inspection of Torque Converter

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

When installing transaxle to engine, attach fixing bolts in accordance with the following standard.

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

When turning crankshaft, turn it clockwise as viewed from
front of engine.

When tightening the tighten bolts for the 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" (QR engine), EM-173, "TIMING CHAIN" (VQ engine).

After converter is installed to drive plate, rotate crankshaft several turns and make sure that tran-
saxle rotates freely without binding.

Install POS sensor. Refer to EM-145, "Removal and Installation" .

After completing installation, check for A/T fluid leakage, A/T fluid level, and positions of A/T. Refer to AT-
14, "Checking A/T Fluid" , AT- 2 1 5 , "Adjustment of A/T Position" , AT- 2 1 5 , "Checking of A/T Position" . : 52 N·m (5.3 kg-m, 38 ft-lb)
