b) If the camshaft oil seal is to be renewed
then the camshaft timing sprocket must
be removed
2 Remove the camshaft bearing caps (see
illustrations), making a careful note of their
fitted positions for reference when refitting .
The caps are numbered (see illustration) but
mark the side nearest the front of the cylinder
head. No. 1 cap is the one with a small oil seal
on it.
3 Remove cap nos. 5, 1 and 3 in that order.
Now undo the nuts holding 2 and 4 in a
diagonal pattern. The camshaft will lift the
caps up as the pressure of the valve springs is
exerted. When they are free, lift the caps off
along with the camshaft. The oil seal on the
front end of the camshaft will come with it.
Depending on tappet type, proceed as
follows:
Shim bucket tappets
4 The tappet buckets are now exposed and
may be lifted out (see illustration). Take each
one out in turn, prising the little disc out of the
bucket by inserting a small screwdriver either
side and lifting the disc away. On its reverse,
each disc is engraved with a size (eg. 3.75).
This is its thickness number. Note the number
and then clean the disc and refit it, number
side down. There are eight of these and they
must not be mixed up. On assembly, each
disc must go back into the bore from whence
it came. This problem exists also for the
valves, so a container for each valve assembly
