Crankshaft
Installation
...
A
Caution
Always check the main bearing journal clearance (see
page 5-15), before final assembly of the crankshaft.
Failure to correctly select crankshaft bearings will result
in severe engine damage.
Note:
•
Crankshafts and balancer shafts are graded. If
the crankshaft is replaced, it must be grade-
matched with the balance shaft. For
identification, both are marked adjacent to the
alignment dots either
'A'
or
'8'.
Always match
an 'A' grade crankshaft with an 'A' grade
balancer shaft and vise-versa.
Note:
• A '8' grade component does not indicate
inferior quality
to
an 'A' grade component.
1. Select and fit new main and big end bearing shells
using the selection processes detailed on pages 5-14
and 5-15.
2.
Lubricate all bearings with engine oil.
3. Ensure that the crankshaft is clean, and that the oil
ways within the crankshaft are clean and free from
blockages and debris.
4. Install the crankshaft ensuring that the crankpins
align with the corresponding big ends.
