5. Heat the cylinder head (1) in a wear tank to approx.
80_C.
6. Cool down the new valve guide (2) with liquid nitro-
gen.
Notice
Do not touch the cooled valve guide by hand.

8. Check the valve guide bore with GO / NO GO gauge
(9).
The GO side (marked ’0’) should just still drop. If the
GO side cannot be inserted, the bore of valve guide
should be reamed.
Notice
Perform the check only on cooled down cylinder
head.

Checking and Machining
1. Clean the valves and do visual check.
Valves with wobbled valve disc, with worn or scored
valve stem should be replaced.
2. Measure valve disc height ’h’.

3. Machine the valve.
Notice
Pay attention to setting angle ’a’.
4. Measure radial runout between valve stem and
valve seat.

Measurement Procedure
1. Remove the cylinder head cover.
2. Rotate the engine in the direction of engine rotation
until the intake valve of NO.1 cylinder is completely
closed. The cam lobe faces up (arrow).
Notice
Do not rotate the engine at the bolt of the crankshaft
sprocket. Do not rotate the engine in the opposite di-
rection of engine rotation. If do, thiswill cause seri-
ous measuring errors.
3. Install the dial gauge holder and dial gauge (7) with
the extension (8) to the cylinder head and position
the tracer pin (9) onto the valve tappet (intake valve
of cylinder NO.1) with a preload of min. 3mm.
Notice
The tracer pin should be positioned exactly vertical.

4. Set the dial gauge to ’0’.
5. Rotate the engine further in direction of rotation until
the dial gauge has moved back by 2mm (valve lift) to
1mm.
6. Check the timing.
NewAT DC 11 . 3 3_
After approx. 20,000kmAT DC 1 2_
Notice
If timing is out standard, the camshaft should be
checked for wear and the timing chain for stretch. If
adifferenceofmorethan4_exists, the timing chain
should be replaced.
7. Replace the gasket and install the cylinder head
cover.

8. Pull off the camshaft.
Notice
Be careful not to miss front locking washer.
9. Pull out the locking washer.
Notice
Check the condition of locking washer and replace if
necessary.
Installation Procedure
1. Insert the locking washer.
2. Check the valve tappet and ensure that tappet
moves smoothly.
3. Coat the camshaft with oil and install the camshaft
onto the cylinder head so that the TDC marking (ar-
row) is positioned upward vertically.
4. Install the camshaft bearing caps according to
markings(1, 2, 3 etc.).

Notice
Replace the seal.
Before installation, by pumping in the oil approx. 10
times, fill the oil.
9. Remove the engine lock.
10. Check the TDC marking of OT on the crankshaft.

11. Place the fitting tool (8) onto the chain link and rivet
the chain pins one by one.
Tightening Torque35-- 40 N∙m (26-- 30 lb-ft)
12. Check the riveting of chain pins and re-- rivet if nec-
essary.
13. Remove the wire.
14. Position the no.1 cylinder at TDC.
In this position, the marking on camshaft / camshaft
bearing cap (arrow) must also be aligned. If the
markings are not aligned, the timing chain must be
re-- set and the injection pump timing has to be set.
