into position using a long reach socket
4.59 Spring seat being fitted over the tops
of the valve springs
4.61 Refitting the hydraulic tappets
stepped surface of the seat (see
illustrations). Note: Depending on age and
specification, engines may have either
concentric double valve springs, or single
valve springs with no lower spring seat.
59 Fit the upper seat over the top of the
springs, then using a valve spring
compressor, compress the springs until the
upper seat is pushed beyond the collet
grooves in the valve stem. Refit the split
collet, using a dab of grease to hold the two
halves in the grooves (see illustration).
Gradually release the spring compressor,
checking that the collet remains correctly
seated as the spring extends. When correctly
seated, the upper seat should force the two
halves of the collet together and hold them
securely in the grooves in the end of the valve.
60 Repeat this process for the remaining sets
of valve components. To settle the
components after installation, strike the end
of each valve stem lightly with a mallet, using
an interposed block of wood to protect the
stem from damage. Check before progressing
any further that the split collets remain firmly
held in the end of the valve stem by the upper
spring seat.
61 Smear some clean engine oil onto the
sides of the hydraulic tappets and fit them into
position in their bores in the cylinder head.
Push them down until they contact the valves,
then lubricate the camshaft lobe contact
surfaces (see illustration).
62 Lubricate the camshaft and cylinder head
bearing journals with clean engine oil, then
carefully lower the camshaft into position on
the cylinder head. Support the ends of the
shaft as it is inserted, to avoid damaging the
lobes and journals (see illustration).
63 Oil the upper surfaces of the camshaft
bearing journals, then fit the bearing caps in
place. Ensure that they are fitted the right way
around and in the correct locations, then fit
and tighten the retaining nuts, as follows:
64 The bearing caps have their respective
cylinder numbers stamped onto them and
have an elongated lug on one side. When
correctly fitted, the numbers should be
readable from the exhaust side of the cylinder
head and the lugs should face the inlet side of
the cylinder head (see illustration).
65 Fit caps Nos 2 and 4 over the camshaft
and tighten the retaining nuts alternately and
diagonally to the specified first stage torque
(see illustration).
66 Smear the cylinder head mating surfaces
of caps Nos 1 and 5 with suitable sealant then
fit them, together with cap No 3, over the
camshaft and tighten the nuts to the specified
first stage torque.
