c. Press-fit the rear oil seal using a drift with outer diameter 115
mm (4.53 in) and inner diameter 90 mm (3.54 in) (A) (commer-
cial service tool).

Press-fit to the specified dimensions as shown.
CAUTION:

Never touch the grease applied to the oil seal lip.

Be careful not to damage the rear oil seal mounting part
of oil pan (upper) and cylinder block or the crankshaft.

Press-fit straight, making sure that rear oil seal does not
curl or tilt.
NOTE:
The standard surface of the dimension is the rear end surface of cylinder block.
6. Install oil pump.

Tighten bolts in numerical order as shown.
7. Install oil pump sprocket, oil pump drive chain and other related
parts if removed.
8. Use a scraper (A) to remove old liquid gasket from mating sur-
faces.

Also remove old liquid gasket from mating surface of oil pan
(upper).

Remove old liquid gasket from the bolt holes and threads.

side (B).

Confirm identification color (A) of valve spring.
6. Install valve spring retainer.
7. Install valve collet.

Compress valve spring using Tool (A). Install valve collet with a magnet hand.
CAUTION:

VALVE DIMENSIONS

Check dimensions of each valve. For dimensions, refer to EM-106, "Valve Dimensions" .

If dimensions are out of the standard, replace valve.
VALVE GUIDE CLEARANCE
Valve Stem Diameter
Measure the diameter of valve stem with a micrometer (A).
Valve Guide Inner Diameter
Measure the inner diameter of valve guide with a bore gauge.
Valve Guide Clearance
(Valve guide clearance) = (Valve guide inner diameter) – (Valve stem diameter).

Intake : White
Exhaust : Orange

4. Heat cylinder head to 110° to 130°C (230° to 266°F) by soaking
in heated oil (A).
5. Press valve guide (1) from camshaft side to dimensions as
shown.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide using suitable tool (A).
VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves are within specifications, perform this pro-
cedure.

Apply prussian blue (or white lead) onto contacting surface 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 cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat.
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 should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-109, "
Valve Seat" .

2. Ream cylinder head (1) 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 (A).
4. Provide valve seats cooled well with dry ice. Press-fit valve seat into cylinder head.
CAUTION:

Never touch cold valve seats directly.

Cylinder head contains heat, when working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set or valve seat grinder, finish valve
seat to the specified dimensions. For dimensions, refer to EM-
109, "Valve Seat" .
CAUTION:
When using valve seat cutter, firmly grip the cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with the cutter or cutting many different times
may result in stage valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. Refer to EM-70, "
VALVE SEAT CONTACT" .
VALVE SPRING SQUARENESS

Set try square along the side of valve spring and rotate the
spring. Measure the maximum clearance between the top of
valve spring and try square.
CAUTION:
Never remove valve spring seat from valve spring.

If it exceeds the limit, replace valve spring (with valve spring
seat).

VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD

Check valve spring pressure with valve spring seat installed at
the specified spring height.
CAUTION:
Never remove valve spring seat from valve spring.

If the installation load or load with valve open is out of the standard, replace valve spring (with valve spring
seat).

Unit: mm (in)
NOTE:

Piston is available together with piston pin as an assembly.

There is no piston pin (piston pin hole) grade.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used
1. Apply connecting rod big end diameter grade stamped (C) on
connecting rod side face to the row in the “Connecting Rod
Bearing Selection Table”.
2. Apply crankshaft pin journal diameter grade stamped on crank-
shaft front side to the column in the “Connecting Rod Bearing
Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Connecting Rod Bearing Selection
Table”.
4. Apply the symbol obtained to the “Connecting Rod Bearing Grade Table” to select connecting rod bearing.
When Crankshaft and Connecting Rod are Reused
1. Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-
vidually. Refer to EM-97, "
CONNECTING ROD BIG END DIAMETER" and EM-100, "CRANKSHAFT
PIN JOURNAL DIAMETER" .
