COMPONENT PARTS INSTALLATION

Disassembly, inspection and assembly of each component group have been indicated in the preceding

chapter. Before assembly, make sure, again, that all component groups are assembled correctly.

If something wrong is found in a certain component group during assembly, inspect and repair this group

immediately.

Recommended ATF: D-II or DEXRON

(DEXRON

® II

)

GENERAL INSTALLATION NOTES:

(a)

The automatic transaxle is composed of highly precision-finished parts, necessitating careful inspec-
tion before assembly because even a small nick could cause fluid leakage or affect performance.

(b)

Before assembling new clutch discs, soak them in automatic transaxle fluid for at least 15 minutes.

(c)

Apply automatic transaxle fluid on the sliding or rotating surfaces of parts before assembly.

(d)

Use petroleum jelly to keep small parts in their places.

(e)

Do not use adhesive cements on gaskets and similar parts.

(f)

When assembling the transaxle, be sure to use new gaskets and O-rings.

(g)

Dry all parts with compressed air-never use shop rags.

(h)

Be sure to install the thrust bearings and races in the correct direction and position.

(b)

Place the bearing cage onto the drive pinion shaft.

NOTICE: Be careful not to damage the oil seals with the

pinion shaft.

(c)

Using a brass bar and hammer, slightly tap the bearing
cage into the transaxle case until the snap ring groove in
the bore can be seen.

(d)

Using SST, install snap ring into the bore.
SST 09350-32014 (09351-32050)

(e)

Using SST, press in the outer race.
SST 09350-32014 (09351-32100, 09351-32140)

4.

INSTALL COUNTER DRIVE GEAR

(a)

Place a brass bar into the transaxle hole to hold the drive
pinion shaft.

(b)

Using SST, press in the counter driven gear until the
counter driven gaer bearing almost touches the counter
gear.
SST 09350-32014 (09351-32140)

5.

INSTALL NEW LOCK NUT AND ADJUST DRIVE PIN-
ION PRELOAD

(a)

Install the new lock nut.

(b)

Using SST to hold the gear, tighten the nut.

Torque: 280 N·m (2,855 kgf·cm, 206 ft·lbf)

SST 09330-00021, 09350-32014 (09351-32032)

(c)

Turn the gear counterclockwise and clockwise several
times.

(d)

Using a small torque wrench, measure the preload of the
drive pinion.

Drive pinion preload (at starting):

New bearing

1.0-1.6 N·m (10-16 kgf·cm, 8.7-13.9 in.·lbf)

Reused bearing

0.5-0.8 N·m (5-8 kgf·cm, 4.3-6.9 in.·lbf)

If the preload is greater than specified, replace the
bearing spacer.
