TRANSMISSION AND TORQUE CONVERTER
Installing with Alignment Tool
Ensure that the flywheel face, drive plate and hardware are
clean and free from burrs or other surface imperfections.
1. Place the drive plate and annulus (1 Figure 7-23) onto
the torque converter.
2. Place the torque
(Figure 7-24) over the torque converter spigot, making
sure that the tool locates in two of the converter bolt
holes as shown. It is important to note that the converter
drive tube must be protected against damage or
contamination at all times.
3. Apply Loctite® 243 to the threads of four new special
drive plate retaining bolts (2), attaching the drive plate to
the torque converter. Tighten the bolts to 40 Nm (30 lb-
ft). Remove the alignment tool and install the remaining
two bolts. Tighten to a torque of 40 Nm (30 lb-ft).

4. Locate the torque converter and drive plate assembly on
the flywheel. Install three bolts to attach the drive plate to
the flywheel. Check the converter run-out as shown in B
of Figure 7-25, which should not exceed 0.38 mm (0.015
in). Adjust as necessary.
NOTE: In the unlikely event that the run-out exceeds 0.38
mm (0.015 in), remove the converter and check the
a1240
spigot for burrs, remove the drive plate and rotate it
180° on the torque converter. Repeat steps 2 to 4.
5. Remove the torque converter and drive plate/annulus
assembly from the flywheel.
6. Install the converter assembly to the transmission/
A
engine:
a. Install the torque converter with its drive plate/
annulus sub-assembly onto the transmission input
shaft, making sure that the dogs on the converter
pump drive shaft engage with the recesses in the
pump. Also take care not to damage the oil seal.
b. Rotate the engine flywheel so that one bolt hole is in
the six o'clock position.
c. Rotate the torque converter and drive plate
assembly so that one bolt hole is in the six o'clock
position.
d. Install the transmission/torque converter assembly
to the engine.
e. Remove the access plate from the bottom of the
engine flywheel housing and, through the access
hole, fit and hand tighten one bolt (3, Figure 7-23) in
the six o'clock position.
NOTE: It is important to mount washers (4) with the outside
diameter radius against the drive plate, that is,
facing towards the flywheel.
f. Rotate the flywheel until the next bolt hole is
accessible. Apply Loctite 243 to the threads of the
next bolt (3) then fit and hand-tighten. Repeat this
operation until all bolts are installed. Finally, torque
all bolts (3) to 19 Nm (14 lb-ft), rotating the flywheel
