E
ngine - Valve Clearance Check
Gen
eral Procedures

1.
Open the engine compartment and fit paintwork protection
sheets. Open to the service position.
2. Carefully remove both engine covers, taking care not to
damage the plasti c fixings or the rubber inserts.

3. Di
sconnect the batt
ery ground cable.
R
emove the battery cover.
4. Remove the cam cover from the 'A' bank and the 'B' bank;
including the purge valve, the on-plug ignition coils and the air
intake tube / air flow meter / air cleaner cover assembly. Refer
to Operations 12.29.43 and 12.29.44.
5. Rotate the crankshaft so that there are four valves which are
'off the cam' (cam lobes upperm ost), so that their clearance
may be measured.
6. Measure the gap on each of the four valves. Note which valve
has been measured, along with its relevant clearance.
7. Rotate the crankshaft a small am ount so that the next four
valves are 'off the cam'. Measure and note the clearances.
Re
peat this step
a further six times, until all valve
clearances have been measured and noted.
8. Refit the cam covers and associated components. Refer to
Operations 12.29.43 and 12.29.44.
9. Refit the engine covers.
10. Move the engine compartment cover from the service position
and connect the gas struts.
11. Remove the paint protection sheets and close the cover.
12. Connect the battery and fit the battery cover.

Install a new sealing wash er to the
drain plug.
Wipe the drain plug an
d
install
it to the oil pan to prevent

to the oil pan body.
2. Remove the oil pan.
3. Remove the gasket from the oil pan body assembly.
11. Remove the oil pan body a ssembly. Refer to Operation

20. Apply new en
gine oil to the co
nnecting rod bearing and to the
crankpin.

21. Carefull
y move the connecting
rod and piston assembly
towards the the crankshaft and connect it to the crankpin.
Rotate the crankshaft slightly if necessary.
22. If necessary, refer to the Spec ification Section for details of
piston and connecting rod orientation.

23 . Install and alig
n the new bearin
g shell to the connecting rod
cap.
24. Apply new engine oil to the bearing shell.

25 . Install th
e cap and NEW bolts to the connecting rod.
1. Note the position of the identification marks and install the cap so that the identification marks are
adjacent to those on the connecting rod.

26. Tighten the bolts as follows:

5.
Install the front cros smember. Refer to Operat
ion 76.10.05.
6. Install the undert ray. Refer to Operation 76.22.90.
7. Install both front wheel and tyre assemblies. Refer to
Operation 74.20.05.
8. Install the timing cover and al l associated components, as
detailed in Operation 12.65.01.
9. Install the twin fan and motor assembly. Refer to Operation
26.25.12.
10. NOTE: When the engine is star ted from cold and run for a
short period only, before being swit ched off, a quantity of oil will
be 'hung up' within the engine because it is not up to operating
temperature.
Should the oil level subsequently be topped-up, the level could
become too high, causing oil burning.
Typically, 0.875 L is hung up.
Refill the engine with the correct specification engine oil.
11. Connect the battery and in stall the battery cover.
