Assembly
Apply high-temperature grease to lubricate the bearing, gears and
frictional surface when assembling the starter.
Carefully observe the following instructions.
PINION PROTRUSION LENGTH ADJUSTMENT
Clearance ``!''
With pinion driven out by magnetic switch, push pinion back to
remove slack and measure clearance ``!'' between the front edge
of the pinion and the pinion stopper.
Clearance ``!'':
Refer to SDS (EL-51).
Movement ``!''
Compare movement ``!'' in height of pinion when it is pushed out
with magnetic switch energized and when it is pulled out by hand
until it touches stopper.
Movement ``!'':
Refer to SDS (EL-51).

CYLINDER HEAD DISTORTION
Warpage of surface:
Less than 0.1 mm (0.004 in)
If beyond the speci®ed limit, replace it or resurface it.
Resurfacing limit:
The resurfacing limit of cylinder head is determined by the
cylinder block resurfacing in an engine.
Amount of cylinder head resurfacing is ``A''.
Amount of cylinder block resurfacing is ``B''.
The maximum limit is as follows:
A + B = 0.1 mm (0.004 in)
Nominal cylinder head height:
139.9 - 140.1 mm (5.508 - 5.516 in)
VALVE GUIDE CLEARANCE
1. Insert the valve stem into the valve guide and move it back,
forth and slide it.
If valve stem makes a clatter and moves back and forth exces-
sively out of line, or if it does not slide well, replace valve or
valve guide, or both.
2. Install valve stem into the valve guide.
3. Measure the de¯ection.
Stem to guide de¯ection limit:
0.1 mm (0.004 in)
(Half of dial gauge reading)
4. If it exceeds the limit, check valve to valve guide clearance.
(1) Measure valve stem diameter and guide inner diameter.
(2) Check that clearance is within the speci®cation.
Valve to valve guide clearance limit:
0.1 mm (0.004 in)
(3) If it exceeds the limit, replace valve or valve guide.
VALVE GUIDE REPLACEMENT
1. Heat cylinder head 150 to 160ÉC (302 to 320ÉF) in oil.
2. Remove the guide with suitable tool.

CAMSHAFT VISUAL CHECK
Check camshaft for scratches, seizure and wear.
CAMSHAFT END PLAY
1. Install camshaft in cylinder head.
2. Measure camshaft end play.
Camshaft end play:
0.065 - 0.169 mm (0.0026 - 0.0067 in)
CAMSHAFT JOURNAL CLEARANCE
1. Measure the inner diameter of camshaft bearing.
Standard inner diameter:
30.000 - 30.021 mm (1.1811 - 1.1819 in)
2. Measure the outer diameter of camshaft journal.
Standard outer diameter:
29.935 - 29.955 mm (1.1785 - 1.1793 in)
If the clearance is greater than the maximum, replace camshaft
and/or cylinder head.
Maximum clearance:
0.045 - 0.086 mm (0.0018 - 0.0034 in)
CAMSHAFT RUNOUT
Camshaft runout [TIR (Total Indicator Reading)]:
Limit 0.02 mm (0.0008 in)
If beyond the limit, replace.

Exhaust
49.505 - 49.695 mm (1.9490 - 1.9565 in)
Cam wear:
Limit 0.15 mm (0.0059 in)
If wear is beyond the limit, replace.

CYLINDER BLOCK DISTORTION AND WEAR
1. Clean upper surface of cylinder block. Using a reliable straight-
edge and feeler gauge, check the ¯atness of cylinder block
surface.
+Check along six positions as shown in ®gure.
Limit:
0.10 mm (0.0039 in)
2. If out of speci®cation, resurface it.
The limit for cylinder block resurfacing is determined by the
amount of cylinder head resurfacing.
Amount of cylinder head resurfacing is ``A''.
Amount of cylinder block resurfacing is ``B''.
The maximum limit is as follows:
A + B = 0.2 mm (0.008 in)
Nominal cylinder block height
from crankshaft center:
227.40 - 227.50 mm (8.9527 - 8.9567 in)
3. If necessary, replace cylinder block.
PISTON-TO-BORE CLEARANCE
1. Using a bore gauge, measure cylinder bore for wear, out-of-
round and taper.
Standard inner diameter ``Db'':
85.000 - 85.030 mm (3.3465 - 3.3476 in)
Wear limit:
0.20 mm (0.0079 in)
Out-of-round (X þ Y):
Less than 0.015 mm (0.0006 in)
Taper (A þ B or A þ C):
Less than 0.010 mm (0.0004 in)
If it exceeds the limit, rebore all cylinders. Replace cylinder block if
necessary.
2. Check for scratches and seizure. If seizure is found, hone it.
