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 follow-
ing standard.
VQ35DE models
VK45DE models
*: No.2 bolt also secures A/T fluid charging pipe.

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- 2 7 4 ,
"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" (for
VQ35DE engine), EM-208, "
INSTALLATION" (for VK45DE
engine).

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