W
ARNING REGARDING THE SERVICING OF VEHICLES FITTED WITH SRS AIR BAGS AND SEATBELTS WITH PRE-
TENSIONERS
W arning
1. Improper servicing or maintenance of any SRS air bag or pre-tensioner fi\
tted seatbelt component, or related parts, could cause serious injury through the SRS air bag or pre-tensioner fitt\
ed seatbelt being activated unintentionally
or accidentally.
2. The SRS-ECU, the driver’s side air bag module, the passenger side air bag module, the pre-tensio\
ner fitted seatbelts and the clock spring, should be removed if there is a chance o\
f them being affected by heat during
painting work.
• 93ºC and above: the SRS-ECU, the driver’s air bag module, the passenger’s air bag module and the clock spring should be removed.
• 90ºC and above: the pre-tensioner fitted seatbelts should be rem\
oved.
3. Servicing and maintenance of any SRS air bag or pre-tensioner fitted sea\
tbelt components, or related parts, must be performed by an authorized Mitsubishi dealer.
4. Servicing and maintenance of any SRS air bag or pre-tensioner fitted sea\
tbelt components, or related parts, must only be undertaken after this service manual (specifically Section 52B-\
SRS air bags) has been carefully studied.

ENGINE – CAMSHAFT, VALVE STEM SEAL11-10



B 
Fitting the valve spring
Fit the valve spring so that the end of the valve spring which has
the smaller radius is on the rocker arm side.



C 
Fitting the valve spring retainer lock
In the same way as when the valve spring retainer lock was
removed, compress the valve spring using the special tool for
compressing valve springs (MD998772), and fit the valve spring
retainer lock.



D 
Fitting the rush adjuster
Caution
If a rush adjuster is being reused, it must be washed and
inspected before fitting.
(Ref: Engine Service Manual)



E 
Fitting the camshaft
1. Remove any sealant from the cylinder head.
2. Apply engine oil to the camshaft cams and journals.
3. Fit the camshaft to the cylinder head.
Caution
Ensure that the inlet and exhaust sides are not the wrong way
round.



F 
Fitting the camshaft bearing cap No.4, the camshaft
bearing cap No.3, the camshaft bearing cap No.5, the
camshaft bearing cap No.2, the rear camshaft bearing
cap, and the front camshaft bearing cap
1. Set the camshaft dowel pins in the position shown in the
diagram.Rocker arm side
