6. INSPECT DIAPHRAGM SPRING FOR WEAR
Using calipers, measure the diaphragm spring for depth and
width of wear.
Maximum:
A: Depth 0.6 mm (0.024 in.)
B: Width 5.0 mm (0.197 in.)
If necessary, replace the clutch cover.
7. INSPECT RELEASE BEARING
Turn the bearing by hand while applying force in the axial
direction.
HINT: The bearing is permanently lubricated and requires no
cleaning or lubrication.
If a problem is found, replace the bearing together with the
hub.
8. INSPECT FLYWHEEL DAMPER FOR GREASE LEAKAGE
If grease has sprayed onto the clutch housing, replace the fly-
wheel assembly.
9. INSPECT FLYWHEEL DAMPER ROTATIONAL
FREEPLAY
(a) Install the 2 bolts to the secondary flywheel at diametrically
opposite positions.
(b) Holding both the bolts, turn the secondary flywheel clockwise
until it stops.
(c) Put matchmarks on the primary and secondary fly±wheels at
this position.
(d) Then rotate the primary flywheel counterclockwise by hand
until it stops.
(e) Put matchmarks on the primary flywheel at this position.
(f) M e a s u r e t h e c i r c u m f e r e n t i a l length between the 2
matchmarks on the secondary flywheel.
Standard:
105 mm (4.134 in.)
(g) Repeat the preceding steps (d) to (f) 4 times and if the
measurement is greater than the maximum length replace
the flywheel assembly.

CLUTCH UNIT INSTALLATION
1. INSTALL CLUTCH DISC AND CLUTCH COVER ON
FLYWHEEL
(a) Insert the SST in the clutch disc, and then set them and the
cover in position.
SST 09301±00110
(b) Align the matchmarks on the clutch cover and fly±wheel.
(c) Tighten the bolts evenly and gradually while pushing SST.
Make several passes around the cover until it is snug.
(d) Torque the bolts on the clutch cover in order shown.
Torque: 19 NVm (195 kgfVcm, 14 ftVlbf)
HINT: Temporarily tighten the No.1 and No.2 bolts.
2. CHECK DIAPHRAGM SPRING TIP ALIGNMENT
Using a dial indicator with roller instrument, check the dia-
phragm spring tip alignment.
Maximum non±alignment:
0.5 mm (0.020 in.)
If alignment is not as specified, using SST adjust the dia-
phragm spring tip alignment.

(d) Check the valve overall length.
Standard overall length:
Intake
98.29±98.79 mm (3.8697±3.8894 in.)
Exhaust
98.84±99.34 mm (3.8913±3.9110 in.)
Minimum overall length:
Intake
98.19 mm (3.8657 in.)
Exhaust
98.74 mm (3.8874 in.)
If the overall length is less than minimum, replace the valve.
(e) Check the surface of the valve stem tip for wear.
If the valve stem tip is worn, resurface the tip with a grinder
or replace the valve.
NOTICE: Do not grind off more than the minimum overall
length.
8. INSPECT AND CLEAN VALVE SEATS
(a) Using a 45° carbide cutter, resurface the valve seats.
Remove only enough metal to clean the seats.
(b) Check the valve seating position.
Apply a thin coat of prussian blue (or white lead) to the valve
face. Lightly press the valve against the seat. Do not rotate
the valve.
(c) Check the valve face and seat for the following:
wIf blue appears 360° around the face, the valve is
concentric. If not, replace the valve.
wIf blue appears 360° around the valve seat, the guide
and face are concentric. If not, resurface the seat.
wCheck that the seat contact is in the middle of the valve
face with the following width:
Intake
1.0±1.4 mm (0.039±0.055 in.)
Exhaust
1.2±1.6 mm (0.047±0.063 in.)
If not, correct the valve seats as follows:
wIf the seating is too high on the valve face, use 15° and
45° cutters to correct the seat.

CYLINDER BLOCK ASSEMBLY
HINT:
wThoroughly clean all parts to be assembled.
wBefore installing the parts, apply new engine oil to all
sliding and rotating surfaces.
wReplace all gaskets, O±rings and oil seals with new
parts.
NOTICE: Apply a generous amount of oil on the sliding surface
of the bearing, and not on the back of it or on the surface to
which it is installed.
1. 2JZ±GTE:
INSTALL OIL NOZZLES (WITH RELIEF VALVES)
Using a 5 mm hexagon wrench, install the oil nozzle with the
bolt. Install the 6 oil nozzles.
Torque: 8.8 NVm (90 kgfVcm, 78 in.Vlbf)
2. INSTALL MAIN BEARINGS
HINT:
wMain bearings come in widths of 20.0 mm (0.787 in.) and
23.0 mm (0.906 in.). Install the 23.0 mm bearings in the
No.1 cylinder block journal position with the main
bearing cap. Install the 20.0 mm bearings in the other
positions.
wUpper bearings have an oil groove and oil holes; lower
bearings do not.
(a) Align the bearing claw with the claw groove of the main
bearing cap or cylinder block.
NOTICE: Install the bearing with the oil hole in the cylinder
block.
(b) Install the bearings in the cylinder block and main bearing
caps.
