1986 TOYOTA CAMRY V20 length

ASSEMBLY OF SECOND COAST BRAKE
PISTON
1. SELECT PISTON ROD
If the band is OK but piston stroke not within the standard value,
select the piston rod.
Piston stroke: 2.0 ± 3.5 mm (0.079 ± 0.138 in.)
There are two lengths of piston rod.
Piston rod length: 95.2 mm l3.748 in.)
96.3 mm (3.791 in.)
2. INSTALL PISTON ROD
(a) Install the plate washer and inner spring to the piston
rod. INSPECTION OF SECOND COAST BRAKE
COMPONENT
If the lining of the brake band is exfoliated or discol-
ored,
or even part of the printed marks is defaced, replace the
brake band.(b) Remove the inner spring, plate washer and pis-
ton rod.
(b) Install the E±ring while pushing the piston.

(Assembly of Valve Body)
(See page AT±308)
1. POSITION NO. 1 PLATE AND NEW GASKETS ON
UPPER VALVE BODY
Position new No. 1 gasket, No. 1 plate and then new No. 2
gasket on the upper valve body.
HINT: Since No. 1 gasket and No. 2 gasket are similar,
use the illustration below to discriminate between them.
2. PLACE UPPER VALVE BODY WITH NO. 1 PLATE AND
GASKETS ON LOWER VALVE BODY
Hold the upper valve body, No. 1 plate and gasket;
securely so they do not separate.
Align each bolt hole in the valve bodies with the gasket;
and plate.
3. INSTALL AND FINGER TIGHTEN BOLTS IN UPPER
VALVE BODY TO SECURE LOWER VALVE BODY
Install and finger tighten the three bolts.
HINT: Each bolt length (mm (in.)) is indicated in the
figure.

5. INSTALL UPPER VALVE BODY COVER GASKETS,
PLATE AND THROTTLE MODULATOR OIL STRAINER
(a) Position a new gasket and plate and then another new
gasket.
HINT: Both gaskets are same one.
(b) Install the oil strainer onto the gasket.
6. INSTALL UPPER VALVE BODY COVER
(a) Position the upper valve body cover.
(b)) Install and finger tighten the eleven bolts.
HINT: Each bolt length (mm (in.)) is indicated in the fig-
ure.
7. INSTALL AND FINGER TIGHTEN BOLT IN LOWER
VALVE BODY
HINT: Bolt length (mm (in)) is indicated in the figure.
8. INSTALL CHECK BALLS
Install the two check balls into the lower valve body. 4. INSTALL LOCK±UP RELAY VALVE SLEEVE STOPPER

14. INSTALL LOWER VALVE BODY COVER
(a) Position the lower valve body cover.
(b) Install and finger tighten the twelve bolts.
HINT: Each bolt length (mm (in.)) is indicated in the fig-
ure. 9. INSTALL LOWER VALVE BODY COVER GASKETS
AND NO. 2 PLATE
Position a new gasket and plate and then another new
gasket.
HINT: Both gaskets are same one.
12. INSTALL B0 ACCUMULATOR ASSEMBLY
(a) Coat new O±rings with ATF and install them to the
piston.
(b) Insert the spring and piston into the cylinder. 11. TIGHTEN BOLTS OF UPPER AND LOWER VALVE
BODIES
(a) Tighten the thirteen bolts in the lower valve body.
Torque: 67 kg±cm (58 in.±Ib, 6.6 N±m)
(b) Tighten the fourteen bolts in the upper valve
body.
Torque: 67 kg±cm (58 in.±lb, 6.6 N±m)

13. INSTALL SOLENOIDS
(a) Coat new O±rings with ATF and install them to the so-
lenoids.
(b) Install the lock±up. solenoid.
(e) Install and torque the bolt:
HINT: Bolt length (mm (in.)) is indicated in the figure.
Torque: 67 kg±cm (58 in.±Ib, 6.6 N±m)
(c) Plate the check ball on No. 1 gasket.
(d) Install the B0 accumulator assembly.
(e) Install and torque the three bolts.

(b) Using a spring tension gauge and SST, measure the pre-
load.
SST 09326±20011
HINT: Turn the driven pinion right and left two or three
times to allow the bearings to settle.
Preload (at starting) :
New bearing
1.8±2.9kg (4.0±6.41b, 18±28N)
Reused bearing
0.9± 1.4 kg (2.0±3.1 Ib,9± 14 N)
wIf preload is greater than specification, replace the
bearing spacer.
wIf preload is less than specification, retighten the nut 5
± 10
° at a time until the specified preload is rechecked
If the maximum torque is exceeded while retightening
the nut, replace the bearing spacer and repeat the pre-
load procedure.
Do not back off the pinion nut to reduce the preload.
Maximum torque: 2,400 kg±cm (174 ft±Ib, 235 N±m)
NOTICE: Using the soft jaws, hold the bearing cage
in a vise.
5. ADJUST DRIVEN PINION PRELOAD
(a) Using SST, torque a new nut.
SST 09326±20011
Torque: 1,000 kg±cm (72 ft±Ib, 98 N±m)
HINT: Use a torque wrench with a fulcrum length of
42.5 cm (16.732 in.). 4. INSTALL DRIVEN PINION REAR SIDE BEARING
(a) Install the bearing cage to the driven pinion.
(b) Using a press and SST, install the rear side bearing to
the driven pinion.
SST 09506±35010 3. INSTALL SPACER
