INSPECTION
Installation and Inspection of Torque Converter
lAfter 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.
lWhen installing A/T assembly to engine assembly, tighten bolts
to the specified torque using sequence shown.
*: Tightening the bolt with air breather tube bracket.
lAlign 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 toAT-247,
"COMPONENTS".
CAUTION:
lWhen turning crankshaft, turn it clockwise as viewed from
the front of engine.
lWhen 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 toEM-85, "
INSTALLATION".
lAfter converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that A/T rotates freely without binding.
lInstall crankshaft position sensor (POS). Refer toEM-36, "Removal and Installation".
lAfter completing installation, check A/T fluid leakage, A/T fluid level, and A/T positions of A/T. Refer toAT-
12, "Checking A/T Fluid",AT- 2 11 , "Checking of A/T Position". Distance “A”: 25.0 mm (0.98 in) or more
