Tools Required
001 589 32 21 00 Dial Gauge
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’.
Commercial Tool

6. Check the timing.
New
After approx. 20,000kmATDC 11.33°
ATDC 12°
Notice
If timing is out standard, the camshaft should be checked
for wear and the timing chain for stretch. If a difference of
more than 4° exists, the timing chain should be replaced.
7. Replace the gasket and install the cylinder head cover.
Tightening Torque 10 Nm
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 direction
of engine rotation. If do, this will cause serious 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.

4. Install the camshaft bearing caps according to markings(1,
2, 3 etc.).
7. Remove the camshaft bearing cap.
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 (arrow) is positioned
upward vertically.

10. Check the TDC marking of OT on the crankshaft.8. Install the chain tensioner.
Tightening Torque 80 Nm
Notice
Replace the seal.
Before installation, by pumping in the oil approx. 10 times,
fill the oil.
9. Remove the engine lock.
Notice
If max. length ‘L’ of the 12-sided bolt exceeds 53.6mm,
replace it.

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.
14. Position the no.1 cylinder at TDC.
11. Place the fitting tool (8) onto the chain link and rivet the
chain pins one by one.
12. Check the riveting of chain pins and re-rivet if necessary.
13. Remove the wire.
Tightening Torque 35 - 40 Nm

Installation Procedure
1. Put the same alignment mark on the new crankshaft
sprocket as in the old sprocket.
Notice
Check the timing chain, camshaft sprocket, injection pump
timing sprocket, oil pump chain and oil pump sprocket for
wear and replace if necessary.
2. Install the new crankshaft sprocket (12) by using a drift (21).
Notice
Align the groove of sprocket and woodruff key (arrow)
exactly.
Drift 116 589 07 15 00
3. Fit the timing chain (4) on the crankshaft sprocket (12).
Notice
