Note
Make sure to deduct the thickness of the straightedge.
Using a vernier caliper and straightedge, measure the dimension (B) shown in the illustration and check that the dimension (B) is more than the dimension (A), which was measured in the previous step.
Standard |
---|
B = A + 1 mm (0.0394 in.) or more |
Note
Make sure to deduct the thickness of the straightedge.
If the automatic transaxle assembly is installed to the engine assembly with the torque converter assembly not sufficiently inserted, the torque converter assembly may be damaged.
Do not include the thickness of the set block.

(B) | 50 mm (1.97 in.) | 46 N*m (469 kgf*cm, 34 ft.*lbf) |
(C) | 32 mm (1.26 in.) | 44 N*m (449 kgf*cm, 32 ft.*lbf) |
33 mm (1.30 in.) | 43 N*m (438 kgf*cm, 32 ft.*lbf) |
Note
When tightening the bolts, make sure that the contact surfaces of the engine assembly and automatic transaxle assembly are in close contact with one another.
Do not use excessive force when installing the automatic transaxle assembly.
Check that the torque converter assembly rotates.
Make sure that the wire harness and other similar items are not pinched between the contact surfaces.
In order to protect the automatic transaxle oil pan sub-assembly, place attachments on the transmission jack.
Make sure that the attachments and automatic transaxle oil pan sub-assembly are centered on the transmission jack.
To prevent the automatic transaxle oil pan sub-assembly from being deformed, do not place any attachments under the automatic transaxle oil pan sub-assembly.
Secure the automatic transaxle assembly to the transmission jack using a belt, etc. to prevent it from falling.
