INSPECTION
Installation and inspection of torque converter

After inserting a torque converter to a transaxle, be sure to
check distance “A” to ensure it is within the reference value limit.
InstallationECS004ND
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing transaxle to the engine, 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 to the specified torque. Refer to AT- 4 1 6 , "
Com-
ponents" .
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 transaxle rotates freely without binding.

After completing installation, check for fluid leakage, fluid level, and the positions of A/T. Refer to AT- 1 6 ,
"Checking A/T Fluid" , AT- 4 0 9 , "Control Cable Adjustment" .
