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.

●

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. Refer to 

AT-278,

"COMPONENTS"

 .

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. Refer to 

EM-74, "INSTALLATION"

 .

●

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

●

Install crankshaft position sensor (POS). Refer to 

EM-38, "Removal and Installation (AWD Models)"

 .

●

After completing installation, check A/T fluid leakage, A/T fluid level and A/T position. Refer to 

AT-13,

"Checking A/T Fluid"

 , 

AT-228, "Checking of A/T Position"
