Crankcases; Removal; Disassembly - Triumph Rocket III Classic Service Manual

Crankcases
The following procedures often require lifting of heavy
components. To avoid injury, always lift heavy
components with a hoist or block and tackle and never
attempt to manually lift items that are too heavy. Injury
may result from failure to use the correct lifting
equipment.
The upper and lower crankcases are machined as a
matched set and must never be assembled to non-
matching halves. Doing so will cause seizure of the
engine.
Note:
• The crankcase halves may be separated with
the cylinder head fitted.
• If the crankshaft main bearing she"s are
removed from the crankcase, remove and
collect the three loose-fitting piston cooling jets
from the upper crankcase.

If the big end bolts have been loosened or removed, new
bolts must be installed
A.
caution
During crankcase assembly, ensure the three piston
cooling jets are re-installed. If the piston cooling jets are
omitted, oil pressure will be reduced. Running the
engine with low oil pressure will cause severe engine
damage.
