CRANKSHAFT ASSEMBLY 14
15 Ensure that the tops of the main bearing caps
are stamped with their relevant position number.
Remove the main bearing caps, the lower half of
the shell bearings and the upper and lower thrust
washers. Keep the bearings with their relevant
caps.
16 Lift out the crankshaft. Remove the upper half
of the bearings and keep each bearing with its
relevant lower half and cap.
To fit
1 Ensure that all lubricating oil passages are clean
and free from restriction.
2 Clean the main bearing housings and the upper
half of the bearings. Fit the shell bearings with the
location tags fitted correctly in their recesses.
Lubricate the bearings with clean engine lubricating
oil.
3 Ensure that the main journals of the crankshaft
are clean. Put the crankshaft in position on the
upper bearings.
4 Clean and lubricate the upper half thrust washers
and slide them into their recesses on both sides of
the bearing housing. Ensure that the slotted sides
of the thrust washers are towards the crankshaft.
5 Clean the bearing caps and the lower half of the
bearings. Fit the bearings to the caps with the
location tags fitted correctly in their recesses.
Lubricate the bearings with clean engine lubricating
oil.
6 Clean the lower half thrust washers and lubricate
them with clean engine lubricating oil. Fit the thrust
washers on both sides of the bearing cap for the
centre main bearing.
7 Check that the location thimbles for the main
bearing caps are fitted correctly in the caps or in
the cylinder block. Fit the bearing caps in their
correct positions (as shown by the position number
stamped on the top of the cap) with the location
tags of the bearings on the same side. In this
position the serial numbers stamped on the bearing
caps will be in line. The serial number stamped on
the bearing caps must be the same as the number
stamped on the bottom face of the cylinder block.
The third and fifth bearing caps of six cylinder
engines are not stamped with a serial number.
