Thickness Inspection
1. Using a micrometer, check thickness of disc rotor. If thickness is
outside the standard, replace disc rotor.
2. If runout is still out of the specification, grind rotor with on-car
brake lathe (″MAD, DL-8700″, ″AMMCO 700 and 705″ or equiv-
alent) until runout becomes within the specified limit.
Brake Burnishing ProcedureEFS006JS
Burnish the new braking surfaces according to following procedure after refinishing or replacing disc rotors,
pads, or if a soft pedal occurs at very low mileage.
CAUTION:

Be careful of vehicle speed because brake does not operate easily until pad and disc rotor are
securely fitted.

Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool brake.
4. Repeat steps 1 to 3 until pad and disc rotor are securely fitted.Standard thickness : 24.0 mm (0.945 in)
Repair limit thickness : 22.0 mm (0.866 in)
Maximum uneven wear
(measured at 8 positions): 0.02 mm (0.0008 in)

12. Remove camshafts.
13. Remove valve lifters.
NOTE:
Identify installed positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nal of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set dial indicator (A) vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height with a micrometer (A).
2. If it exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL OUTER DIAMETER
Measure the outer diameter of camshaft journal with a micrometer
(A).
CAMSHAFT BRACKET INNER DIAMETER

Tighten camshaft bracket bolts with specified torque. Refer to EM-51, "INSTALLATION" for the tightening
procedure.Standard : Less than 0.02 mm (0.0008 in).
Limit : 0.05 mm (0.0020 in)

Measure the inner diameter of camshaft bracket with a bore
gauge (A).
CAMSHAFT JOURNAL OIL CLEARANCE

(Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)

If it exceeds the limit, replace camshaft or cylinder head, or both.
NOTE:
Camshaft bracket cannot be replaced as a single part, because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play
1. Install camshaft in cylinder head. Refer to EM-51, "INSTALLATION" for tightening procedure.
2. Install dial indicator in thrust direction on front end of camshaft.
Read the end play of dial indicator (A) when camshaft is moved
forward/backward (in direction to axis).

Measure the following parts if out of the standard.
–Dimension “A” for groove of cylinder head No. 1 journal
–Dimension “B” for camshaft flange

Refer to the standards above, and then replace camshaft and/
or cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.
