VALVE CLEARANCE ADJUSTMENT
NOTE:
1. Valve clearance should be inspected and adjusted
while the engine is cool.
2. The tightening of the camshaft bearing cap and
camshaft carrier assembly should be checked
before inspecting and adjusting valve clearance.
INSPECTION
1. Remove cylinder head noise insulator cover and
cylinder head cover.
Refer to “Cylinder Head” in this manual.
2. Disconnect all harness connecters of the injector
and remove harness assembly.
3. Drain oil from oil rail assembly.
4. Remove injector clamp nuts and fixing bolts to take
out injector assembly.
5. Loosen oil rail bolts, remove oil rail assembly.
6. Set cylinder No.1 to the TDC at the compression
stroke. Make sure that there is play in cylinder No.1
tappets on inlet and exhaust sides and that there is
no play in cylinder No.4 tappets.
7. Measure valve clearance at No.1 TDC (Refer to the
black circles indicated in the illustration).
Standard Valve clearance:
Intake valve: 0.15 mm (0.0059 in) ± 0.05 mm (0.0020 in)
Exhaust valve: 0.25 mm (0.0098 in) ± 0.05 mm (0.0020 in)
8. Turn the crankshaft one turn to set No.4 cylinder
TDC at the compression stroke.
9. Measure valve clearance at No.4 TDC (Refer to the
black circles indicated in the illustration).
Standard Valve clearance:
Intake valve: 0.15 mm (0.0059 in) ± 0.05 mm (0.0020 in)
Exhaust valve: 0.25 mm (0.0098 in) ± 0.05 mm (0.0020 in)
10. If measured value is outside standard value,
readjust the valve clearance.
ADJUSTMENT
For valve clearance adjustment, follow the procedure
given below.
1. Set cylinder No.1 or No.4 to the TDC at the
compression stroke.
Set the valve clearance adjusting tool on the tappet
requiring adjustment.
After making sure of the correct setting of the
special tool, depress the tappet by turning the bolt.
Valve Clearance Adjusting Tool: 5-8840-2590-0
NOTE: Before depressing the tappet, set the tappet
notch in the direction where adjuster can be easily
taken out.
2. Take out the adjuster using a small screw driver and
finger magnet.

REMOVAL
Prior to removal, be sure to confirm and record the
group code of the injector installed using Tech2.
1. Disconnect battery ground cable.
2. Remove air cleaner cover and air duct.
3. Remove intercooler.
Refer to “Intercooler” in this manual.
4. Remove PCV hose and pipe.
5. Remove cylinder head noise insulator cover.
6. Remove high pressure oil pipe.
CAUTION:
1) Sleeve nut should be loosened with cloth tied
around it to prevent oil from spurting due to the
remaining pressure.
2) The high pressure pipe should be disconnected
with a cloth tied around the intake manifold
glow plug to prevent oil from flowing out of the
oil rail.7. Loosen eye bolt of fuel pipe at fuel pump side.
NOTE: Cloth should be put around the loosened eye
bolt to prevent fuel from flowing out.
8. Remove fuel return hose at chassis side.
9. Remove PCV hose to cylinder head cover.
10. Remove cylinder head cover.
11. Drain the oil from oil rail assembly.
12. Record the identification marking of injector for
each cylinder which is indicated on the upper
portion of injector.
There are nine kinds of identification marking
available, one alphabet letter and one numeral
letter.
In case three kinds of markings are given, one
alphabet letter (sometimes printed) and one
numeral letter, top priority is given to the one
alphabet letter and one numeral letter.
