(d) TORQUE WHEN USING EXTENSION TOOL WITH
TORQUE WRENCH
(1) In case of tightening by extending the entire length
of the torque wrench combined with SST or tool, if
you tighten until the reading of the torque wrench
reached the specified torque value, the actual
torque becomes excessive.
(2) In this text, only the specified torque is described.
In case of using SST or extension tool, find the read-
ing of the torque wrench by the formula.
(3) Formula T'=T x L2/(L1 + L2)
T'Reading of torque wrench {NVm (kgfVcm, ftVlbf)}
TTorque {NVm (kgfVcm, ftVlbf)}
L1Length of SST or tool (cm)
L2Length of torque wrench (cm)

67. REMOVE 1ST & REVERSE BRAKE RETURN SPRING
SUB-ASSY
(a) Place SST on the return spring, and compress the return
spring with a press.
SST 09387-00070
(b) Using a snap ring expander, remove the snap ring.
NOTICE:
Stop the press when the spring sheet is lowered 1 -
2 mm (0.039 - 0.078 in.) from the snap ring groove, to
prevent the spring sheet from deforming.
Do not expand the snap ring excessively.
68. INSPECT 1ST & REVERSE BRAKE RETURN SPRING
SUB-ASSY
(a) Using a vernier calipers, measure the free length of the
spring together with the spring seat.
Standard free length: 17.61 mm (0.6933 in.)
69. REMOVE 1ST & REVERSE BRAKE PISTON
(a) Apply compressed air (392 kPa, 4.0 kgf/cm
2, 57 psi) to the
transaxle case to remove 1st & reverse brake piston.
NOTICE:
Blowing off the air may cause the piston to jump-out.
When removing the piston, hold it by your hand using
a waste cloth.
Take care not to splash ATF when air-blowing.
(b) Remove the 2 O-rings from the 1st & reverse brake pis-
ton.

(e) Using SST and a torque wrench, measure the turning
torque of the bearing while rotating SST at 60 rpm. When
the measured value is not within the specified value,
gradually tighten the nut until it reaches the specified val-
ue.
SST 09387-00080
Turning torque at 60 rpm:
New Bearing
0.51 - 1.02 NVm (5.1 - 10.0 kgfVcm, 4.4 - 8.7 in.Vlbf)
Used Bearing
0.26 - 0.51 NVm (2.7 - 5.2 kgfVcm, 2.3 - 4.5 in.Vlbf)
HINT:
Use a torque wrench with a fulcrum length of 160 mm (6.3 in.).
(f) Tighten the nut gradually until the specified rotation
torque of tapered roller bearing is measured.
Torque: 350 NVm (3,569 kgfVcm, 258 ftVlbf) (a limit)
(g) Using a chisel and hammer, stake the front lock washer.
98. INSTALL INPUT SUN GEAR
(a) Coat the 2 thrust bearings with ATF.
(b) Install the 2 thrust bearings, the bearing race and the front
planetary sun gear to the front planetary gear assy.
NOTICE:
Install the bearing race on the side of the front plane-
tary carrier. Be careful about the orientation of the
race.
Installing thrust bearing and front sun gears, be care-
ful about the orientation of the parts.
Install the bearing race on the side of the front sun
gear. Be careful about the orientation of the race.
Install the thrust bearing and the race after holding
the parts on the rear planetary carrier by applying
grease. Be sure the assembling order.

NOTICE:
Because the bolt A is a seal bolt, apply the seal packing to
new bolts and tighten them within 10 minutes after applica-
tion.
132. INSPECT INPUT SHAFT ENDPLAY
(a) Using a dial indicator, measure the input shaft end play.
End play: 0.262 - 1.249 mm (0.0100 - 0.0494 in.)
133. FIX AUTOMATIC TRANSAXLE ASSY
(a) Fix the transaxle assy.
