B1EE02K1 - 206 DW8 ENGINE

CHECKS AND ADJUSTMENTS VALVE CLEARANCES

Minimum time for engine cooling : 2 H .

DW8 ENGINE

Remove :

- the style cover
- the air distributor

Disconnect and move aside The hose (1) .

Remove :

- the upper cylinder head cover (2)
- the EGR valve hose (3)
- the lower cylinder head cover (4)

1 - METHOD OF CHECKING

Operating clearance in mm :

- inlet : clearance 0,15
- exhaust : clearance 0,30

Tolerance : +/-0,07 .

| cylinder no. 4 on the rock | cylinder no. 1 on the rock
--- | --- | ---
check inlet valves | 1 - 2 | 4 - 3
check exhaust valves | 1 - 3 | 4 - 2

Note the clearances .

2 - VALVE CLEARANCE ADJUSTMENT

DW8 ENGINE

If the clearances (J) noted are incorrect, remove :

- the camshaft
- the tappets (5)
- the adjustment shims (6)

Measure the thickness (E) of the adjustment shims (6) .

Determine the thickness of adjustment shims (6) to be fitted by referring to the example (column A or B) .

WARNING : after work on the cylinder head (replacement of camshaft, tappets or valves or valve grinding), fit adjustment shims (6), of thickness E = 2,425 mm .

To determine the thickness of shims (6) to be fitted finally, refer to the example (column C) .

ALL MODELS

3 - EXAMPLE

| A | B | C
--- | --- | --- | ---
operating clearance | 0,15 | 0,30 | 0,15
clearance measured | 0,25 | 0,20 | 0,45
difference | + 0,10 | - 0,10 | + 0,30
E | 2,35 | 2,725 | 2,425
shims to be fitted | 2,450 | 2,625 | 2,725
clearance obtained | 0,15 | 0,30 | 0,15

DW8 ENGINE

Fit the adjustment shims (6) thus determined then the tappets (5) .

Fit :

- the camshaft
- the camshaft bearing caps

Tighten the camshaft bearing caps to 2 m.daN .

Fit :

- the lower cylinder head cover (tightening torque : 0.43 da.Nm)
- the upper cylinder head cover (tightening torque : 0.8 da.Nm)

Continue the fitting operations in the reverse order to removal .
