2B•12 Engine removal and general overhaul procedures
16 Engine overhaul -
reassembly sequence
1 Before reassembly begins, ensure that all
new parts have been obtained and that all
necessary tools are available. Read through
the entire procedure to familiarise yourself
with the work involved and to ensure that all
items necessary for reassembly of the engine
are at hand. In addition to all normal tools and
materials, it will be necessary to obtain the
Rover sealant kit LVV 10002. Carefully read
the instructions supplied with the sealant kit
and take care not to allow the sealant to
contact the fingers, as it will bond skin.
2 In order to save time and avoid problems,
engine reassembly can be carried out in the
following order:
a) Crankshaft.
b) Piston/connecting rod assemblies.
c) Oil pump.
d) Sump.
e) Flywheel.
f) Cylinder head.
g) Timing belt inner cover, tensioner and
sprockets, and timing belt.
h) Engine external components.
3 At this stage, all engine components should
be absolutely clean and dry, with all faults
17.3 Piston ring fitting details and top
surface markings
17.4 Piston ring end gap locations
A Top compression ring
B Second compression ring
C Oil control ring
D Oil control ring spring
repaired, and should be laid out (or in
individual containers) on a completely clean
work surface.
17 Piston rings - refitting
3
1 Refer to Section 13 for inspection details.
2 Once all rings have been checked, they can
be installed. Ensure that each ring is refitted
only to its matched piston and bore.
3 Install the new rings by fitting them over the
top of the piston, starting with the oil control
ring spring. Note that all rings must be fitted
with the word TOP uppermost (see
illustration).
4 With all the rings in position, space the ring
gaps as shown (see illustration), noting that
the FRONT marking shown is usually in fact
an arrow mark on the piston crown and
indicates the timing belt end of the engine.
18 Crankshaft - refitting and
main bearing running
clearance check
4
Selection of bearing shells
1 The main bearing running clearance is
controlled in production by selecting one of
three grades of bearing shell. The grades are
indicated by a colour-coding marked on the
edge of each shell which governs the shell’s
thickness, as follows:
a) Green - Thin.
b) Blue - Intermediate.
c) Red - Thick.
2 If shells of differing grades are to be fitted
to the same journal, the thicker shell must
always be fitted to the main bearing ladder
location. Bear this carefully in mind when
ordering replacement shells for Nos 2, 3 and 4
bearings.
3 If the bearing shells are to be renewed, first
check and record the main bearing code
letters stamped on the right-hand front face of
the main bearing ladder (see illustration). The
letters are read with the ladder inverted, No 1
bearing’s code letter then being at the top and
the remainder following in order from the
engine’s timing belt end.
4 Secondly, check and record the crankshaft
journal code numbers stamped on the
crankshaft’s right-hand web, No 1 journal’s
code number being the first. If the original
crankshaft is to be re-used, the size grade can
be checked by direct measurement, as
described in Section 14.
5 Note that if the crankshaft is found to be
excessively worn, then it must be renewed
and the code numbers of the new component
must be used instead to select a new set of
bearing shells.
6 Matching the codes noted to the following
table, select a new set of bearing shells.
Ladder code Crankshaft
letter code number Shells
A 1 Blue, Blue
A 2 Red, Blue
A 3 Red, Red
B 1 Blue, Green
B 2 Blue, Blue
B 3 Red, Blue
C 1 Green, Green
C 2 Blue, Green
C 3 Blue, Blue
