INSTALLATION
Installation of the remaining components is in the reverse order of
the removal, while paying attention to the following work.

If removed install drive plate.
–Align dowel pin of crankshaft rear end with pin holes of each
parts to install.
–Install drive plate, reinforcement plate and pilot converter as
shown.
–Face chamfered or rounded edge side to crankshaft.
CAUTION:

When replacing an engine or transmission you must make
sure the dowels are installed correctly during re-assembly.

Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.

When installing transmission to the engine, attach the bolts in
accordance with the following standard.
*: No.2 bolt also secures air breather vent.
–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.
CAUTION:

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

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

After completing installation, check fluid leakage, fluid level, and the positions of A/T. Refer to AT-13,
"Checking A/T Fluid" , AT-234, "Checking of A/T Position" , AT-234, "Adjustment of A/T Position" .

Revision: August 20072004 QX56
DESCRIPTION

All dimensions indicated in the figures are actual.

When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.

When a measuring tape is used, check to be sure there is no elongation, twisting or bending.

Measurements should be taken at the center of the mounting holes.

An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.

The coordinates of the measurement points are the distances measured from the standard line of "X", "Y"
and "Z".
