3. Measure:
Camshaft runout
Out of specification →
Replace.
Maximum camshaft runout:
0.03 mm (0.0012 in)
4. Measure:
Camshaft-journal-to-camshaft-cap
clearance
Out of specification →
Measure the
camshaft journal diameter.
Camshaft-journal-to-camshaft-
cap clearance:
0.05–0.06 mm (0.0020–0.0024 in)
Measurement steps:
Install the camshaft into the cylinder head
(without the dowel pins and camshaft
caps).
Position a strip of Plastigauge 1
onto the
camshaft journal as shown.
Install the dowel pins and camshaft caps.
NOTE:
Tighten the intake and exhaust camshaft
cap bolts in the sequence shown.
Do not turn the camshaft when measuring
the camshaft journal-to-camshaft cap
clearance with the Plastigauge.
T R..
Camshaft cap bolt:
10 N  m (1.0 kgf  m, 7.2 ft  lb)
Remove the camshaft caps and then
measure the width of the Plastigauge 1
.

EPOWRVALVES AND VALVE SPRINGS
Valve seat inspection
1. Eliminate carbon deposits from the valve
with a scraper.
2. Apply a thin, even layer of Mechanic’s
blueing dye (Dykem) onto the valve seat.
3. Lap the valve slowly on the valve seat with
a valve lapper (commercially available) as
shown.
4. Measure the valve seat contact width a
where the blueing dye is adhered to the
valve face. Reface the valve seat if the
valve is not seated properly or if the valve
seat contact width is out of specification.
Replace the valve guide if the valve seat
contact is uneven.

Valve seat reface
1. Reface the valve seat with the valve seat
cutter.
2. Cut the surface of the valve seat with a 45°
cutter by turning the cutter clockwise until
the valve seat face has become smooth.
aSlag or rough surface
CAUTION:
Do not over cut the valve seat. Be sure to
turn the cutter evenly downward at a pres-
sure of 40–50 N (4–5 kgf, 8.8–11 lbf) to pre-
vent chatter marks.

EPOWRCONNECTING RODS AND PISTONS
NOTE:
• Do not move the connecting rod or crank-
shaft until the clearance measurement
has been completed.
 Lubricate the bolts threads and nut seats
with molybdenum disulfide grease.
 Make sure the “Y” mark c on the con-
necting rod faces towards the front side of
the crankshaft.
 Make sure the characters d on both the
connecting rod and connecting rod cap
are aligned.
 Tighten the connecting rod nuts.
Refer to “Connecting rod and piston
installation”.
 Remove the connecting rod and big end
bearings.
Refer to “Connecting rod and piston
removal”.
 Measure the compressed Plastigauge
width e on the crankshaft pin.
If the big end oil clearance is out of speci-
fication, select replacement big end bear-
ings.

2. Select:
 Big end bearings (P

NOTE:
The numbers stamped into the crankshaft web
and the numbers on the connecting rods are
used to determine the replacement big end
bearing sizes.
