F Fixing screws
3.1. Insert the cooling jets into the crankcase.
3.2. Note: There are different types of cooling
jets installed depending on the engine
application. The jets are colour coded.
3.3. Be sure to install the correct jets. Refer to
the relevant parts catalogue for the correct
cooling jet identification.
3.4. Tighten the retaining screws to the correct

4. Install the upper bearing shells as follows:
Figure 294.
D Main bearing shells
G Bearing location tab
4.1. Use a suitable degreasing agent to make
sure that the surface of the upper bearing
shells are clean.
Consumable: Cleaner/Degreaser - General
purpose solvent based parts cleaner
4.2. Assemble the bearing shells into the
crankcase bearing saddles. Make sure that
the location tab engages into the slot as
shown.
4.3. Important: Make sure that the oil-way holes
in the bearing saddles align with the holes
in the bearing shell. If the holes are even
partially misaligned the piston cooling oil jet
will be restricted, causing the engine to fail.
4.4. Lubricate the upper bearing shells with
clean engine oil.
5. Use suitable lifting equipment (if the crankshaft
is lifted manually, two people will be required), to
carefully lower the crankshaft into the crankcase.
DO NOT rotate the crankshaft, the bearing shells
can become dislodged, refer to step 4.
