To fit (crankshaft in position)
Caution: Some shell bearings do not have a hole in the bearing. These shell bearings must only be fitted in
the main bearing cap. If this type of shell bearing is fitted to the cylinder block, the bearing will not receive
lubricating oil and the bearing and the crankshaft journal will be damaged.
1 Clean the upper half of the shell bearing and lubricate the bearing surface with clean engine lubricating oil.
2 Fit the plain end of the upper half of the bearing between the crankshaft journal and the side of the cylinder
block that has the recess for the location tag. Slide the bearing into position until the tag on the bearing is fitted
correctly in its recess in the cylinder block.
3 Clean the lower half of the bearing and the bearing cap, lubricate the bearing surface with clean engine
lubricating oil.
4 Fit the bearing into the cap with the tag of the bearing fitted correctly in the recess in the cap.
5 Ensure that the location thimbles are fitted correctly to the cap or to the cylinder block. Fit the bearing cap
with the location tags of both bearings on the same side.
6 Inspect the setscrews for damage and for distortion and renew them if necessary. Lightly lubricate the
setscrew threads with clean engine lubricating oil. Fit the setscrews and tighten them gradually and evenly to
152 Nm (112 lbf ft) 15,5 kgf m.
7 Ensure that the crankshaft rotates freely. If the thrust washers have been removed and fitted, check the
crankshaft end-float, see Operation 5-4.
8 If the front main bearing was removed:
l Fit the lubricating oil pump, see Operation 10-11.
l Fit the front bridge piece, see Operation 6-14.
l Fit the cover of the timing case, see Operation 6-2.
9 Fit the rear oil seal assembly, see Operation 5-2.
10 Fit the lubricating oil sump, see Operation 10-5 or Operation 10-7, and fill it to the correct level with an
approved lubricating oil.
11 Fit the flywheel housing, see Operation 13-3 and the flywheel, see Operation 13-1.
To inspect
1 Inspect the bearings for wear and for other damage. If a bearing is worn or damaged, renew both halves of
the shell bearings and check the condition of the other bearings.
