To fit
1 Clean the crankcase and the main bearing caps thoroughly. Apply clean engine oil to the main bearings and
fit the upper halves of the main bearings into the crankcase.
2 Install one of the bolts from the front pulley in each end of the crankshaft, fasten a suitable hoist and fit the
crankshaft into the crankcase. Ensure that the "V" mark on the crankshaft gear is in alignment with the line on
the idler gear.
3 Fit the thrust bearings for the centre main bearing. Ensure that the bearings are fitted with the side
identification "BLOCK SIDE" against the crankcase.
4 Fit the main bearings to the bearing caps.
5 Ensure that the tabs on the back of the bearing shells fit into the tab slots of the bearing caps and crankcase.
Caution: Ensure that the main bearing caps are fitted to the correct positions. The numbers on the side of the
crankcase must be the same as the numbers on the bearing caps, and the arrows on the bearing caps must
be directed toward the front of the crankcase.
6 Apply anti-seize compound, CV60890, to the bolts and install the main bearing caps and bolts.
7 Begin at the tab end of the bearing cap first, tighten each bearing cap bolt to a torque of 260 +/- 14 Nm
(190 +/- 10 lbf ft). Make a temporary mark on each bolt and bearing cap. Start with the bolt opposite the tab
end of the bearing cap and again tighten each bolt by an additional 120 +/- 5 degrees.
8 Use a dial test indicator (DTI) to check the end-float of the crankshaft. Ensure that the pointer of the DTI is
against a machined surface. The end-float is controlled by the thrust bearings of the centre main bearing. The
end-float with new bearings must be between 0,15 and 0,51 mm (0.006 and 0.020 in). The maximum
permissible end-float with used bearings is 0,89 mm (0.035 in).
9 Fit the crankshaft front seal and wear sleeve, Operation 5-2.
10 Fit the crankshaft rear seal and wear sleeve, Operation 5-3.
11 Fit the pistons and connecting rod assemblies, Operation 4-1.
12 Fit the flywheel housing, Operation 13-2.
13 Fit the gear case cover, Operation 6-1.
