FUEL INJECTOR AND FUEL TUBE
NOTE:
There is no fuel return path.
a. Remove quick connector cap (floor piping side) (1) from quick connector connection.
b. Disconnect fuel feed hose from hose clamp (1).
c. Hold the quick connector (1) wh ile pushing in tabs (F), and pull
out the hard tube (A).
CAUTION:
• Inserting quick connector re lease hard will not disconnect
quick connector. Hold qui ck connector release where it
contacts and goes no further.
• The tube can be removed when the tabs are completely depressed. Do not twist it more than necessary.
• Do not use any tools to remove the quick connector.
• Keep the resin tube away from heat. Be especially careful
when welding near the tube.
• Prevent acid such as battery electrolyte etc. from getting on the resin tube.
• Do not bend or twist the tube during installation and removal.
• Remove the remaining retainer only when the tube is replaced.
• When the tube is replaced, also replace the retainer.

2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions using suitable tools (A/
B).
• If it exceeds the limit, replace cylinder head.
INSPECTION AFTER DISASSEMBLY
VALVE DIMENSIONS
• Check the dimensions of each valv e. For the dimensions, refer to EM-119, "Cylinder head".
• If dimensions are out of the standard, replace valv e and check valve seat contact. Refer to “VALVE SEAT
CONTACT”.
VALVE GUIDE CLEARANCE
Valve Stem Diameter• Measure the diameter of valve stem using suitable tool (A).
Valve Guide Inner Diameter• Measure the inner diameter of valve guide using suitable tool (A).
Valve Guide Clearance• (Valve guide clearance) = (Valve guide inner diameter) – (Valve stem diameter)
• If the calculated value exceeds the limit, replace valve and/or valve guide. Refer to EM-78, "
Disassembly
and Assembly".
VALVE GUIDE REPLACEMENT
When valve guide is removed, replace with oversized [0.2 mm (0.008 in)] valve guide.
1. To remove valve guide, heat cylinder head to 110 to 130°C (230
to 266 °F) by soaking in heated oil.

CYLINDER HEAD
2. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) force] or suitable tool.
WARNING:
Cylinder head contains heat; when working, wear protective
equipment to avoid getting burned.
3. Ream cylinder head valve guide hole with a suitable tool.
4. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil.
5. Using a suitable tool, press valve guide (1) from camshaft side of cylinder head (2) to dimensions as shown.
WARNING:
Cylinder head contains heat; when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide with a suitable tool.

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.
