CRANKSHAFT AND MAIN BEARINGS—H.2
of the one with the tag (see Fig. H.2). Note: If the
original bearings are to be refitted, identify each
bearing half to its respective position.
5.
If the thrust washers require removal, it is
necessary to remove the center main bearing cap.
Remove the two bottom half thrust washers from
the recesses in the center main bearing cap. The
two top half thrust washers should be removed by
sliding round from one side, using a suitable piece
of thin hard wood, until withdrawal can be effected.
Identify each thrust washer half to its relative
position.
To Refit Main Bearings and Thrust Washers
1.
Refit the main bearing half to the bearing cap
locating it in the tag slot. Liberally oil the other half
of the bearing, insert it plain end first and slide it
around the crankshaft journal until the locating tag
locates in its slot. Oil the cap half of the bearing
and refit the cap securing with the two setscrews
and shim washers. Tighten the setscrews to a
torque setting as given on Page B.1.
Note:
Make sure that the bearing caps are
fitted to their original positions. Each
cap is numbered to correspond with
its engine position commencing with
No. 1 at the front of ,he engine. Each
cap is also marked with a serial
number as stamped on the cylinder
block bottom face. These should
read in line (see Fig. H.3).
2.
Tighten the setscrews on the remainder of the
bearing caps, which were slackened off, ensuring
they are tightened to the correct torque setting.
3.
To refit the thrust washers, liberally oil the two
upper halves with lubricating oil and slide them into
the recesses provided on either side of the main
bearing housing. The steel side of the thrust
washers should be towards the bearing housing
and the cap. Position the two lower halves on
either side of the bearing cap and refit the cap.
Secure with the setscrews tightened to the torque
setting given on Page B.1.
4.
Check the crankshaft end float to ensure that a
clearance of 0.004/0.015 in (0.102/0.38 mm) exists.
5.
Refit the rear main bearing bridge piece together
with new joints between the cylinder block and
bridge piece and new sealing rubbers at the bridge
piece ends (see Fig. H.6). Secure the bridge piece
to the cylinder block with the two recessed screws
and fit the two setscrews securing the rear main
bearing oil seal housing to the bridge piece.
6.
Refit the oil pump as detailed on Page L.5.
7.
Refit the oil delivery and suction pipes to the oil
pump.
8.
Refit the sump strainer and sump.
