ASSEMBLY INSTALLATION
Clean the cylinder bores thoroughly. Apply a
light film of clean engine oil to the bores with a
clean, lint-free cloth.
Install the piston rings on the pistons, if
removed. Refer to the MOT. 2.46L manual for
the procedure.
Lubricate the pistons and rings with clean
engine oil.
CAUTION: Ensure that the connecting rod bolts
do not scratch the crankshaft journals or cylinder
walls. Short pieces of rubber hose slipped over
the connecting rod bolts will provide protection
during installation.
Use Piston Ring Compressor J-5601 to install
the connecting rod and piston assemblies from
the top of the cylinder bores. Ensure that the
arrow on each piston top points to the front of the
engine.

face the camshaft and that the arrows on the
pistons point to the front of the engine.
Raise and support the vehicle.
Install the connecting rod bearing caps and
inserts at their original locations. Refer to
Connecting Rod Bearings Installation for the
procedure.
