Inspection and AdjustmentINFOID:0000000012431690
INSPECTION
Perform inspection as follows after removal, replacement or installation of camshaft or valve-related parts, or if
there are unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to
EM-48, "
Removal and Installation".
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (2) clockwise and align TDC mark (no
paint) (A) to timing indicator (1) on front cover.
• At the same time, check that both intake and exhaust cam lobes of No. 1 cylinder face inside ( ) as shown.
• If the lobes do not face inside, rotate the crankshaft pulley 360 degrees to align as shown.
b. Using suitable tool (A) measure the clearance between the valve lifter and camshaft.

VALVE SEAT CONTACT
• After confirming that the dimensions of valve guides
and valves are within the specifications, perform this
procedure.
• Apply prussian blue (or white lead) onto contacting surfac e of valve seat to check the condition of the valve
contact on the surface.
• Check if the contact area band is continuous all around the circum- ference.
• If not, grind to adjust valve fitting and check again. If the contacting surface still has “NG” conditions (B) even after the recheck,
replace valve seat. Refer to EM-78, "
Disassembly and Assembly".
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Prevent scoring cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.
• Be sure to ream in circles concentric to the valve guide center.This will enable valve seat to fit correctly.
3. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Press-fit valve seats into cylinder head. WARNING:
Cylinder head contains heat; when working, wear protective equipment to avoid getting burned.
CAUTION:
Avoid directly touching cold valve seats.

• Press-fit the piston pin (2) from piston surface (A) to the depth
of 2.35 mm (0.092 in) (b).
• After finishing work, check that the piston (3) moves freely.
10. Using suitable tool (A), install piston rings. CAUTION:
• Do not damage piston.
• Do not damage piston rings by expanding them exces-sively.
• Position each ring with the gap as shown referring to the pis- ton front mark (B).
• Install second ring with the stamped mark (E) facing upward.
11. Install connecting rod bearings to connecting rod and connecting rod cap. • When installing connecting rod bearings, apply new engine oil to the bearing surface (inside). Do notapply engine oil to the back surface, but thoroughly clean it.
• Install the bearing in the center position. NOTE:
There is no stopper tab.
• Check that the oil holes on connecting rod and connecting rod bearing are aligned.
• Install the connecting rod in the dimension (A) as shown.
NOTE:
Install the connecting rod bearing in the center position with
the dimension as shown. For service operation, the center
position can be checked visually.

• If oil clearance is out of the standard, replace piston and piston pin assembly.
• When replacing piston and piston pin assembly. Refer to
EM-94, "
Disassembly and Assembly".
NOTE:
• Piston is available together with piston pin as assembly.
• Piston pin (piston pin hole) grade is provided only for the parts installed at the factory. For service parts, no
grades can be selected. Only grade “0” is available.
PISTON RING SIDE CLEARANCE
• Measure the side clearance of piston ring and piston ring groove with a suitable tool (A).
• If the measured value exceeds t he limit, replace piston ring, and
measure again. If it still exceeds the limit, replace piston also.
PISTON RING END GAP
• Check that cylinder bore inner diameter is within specification. Refer to “PISTON TO CYLINDER BORE CLEARANCE”.
• Lubricate piston (1) and piston ring (2) with new engine oil and then insert (A) piston ring until mi ddle of cylinder (B) with piston,
and measure piston ring end gap using feeler gauge (C).
• If the measured value exceeds t he limit, replace piston ring, and
measure again. If it still exceeds the limit, replace cylinder block.
CONNECTING ROD BEND AND TORSION
• Check using connecting rod aligner.
• If it exceeds the limit, replace connecting rod assembly.

• The identification grade stamped on each part is the
grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
• For reused or repaired parts, measure the dimens ion accurately. Determine the grade by comparing the
measurement with the values of each selection table.
• For details of the measurement method of each part , the reuse standards and the selection method of the
selective fitting parts, refer to the text for the appropriate part.
