4. Taking care not to damage camshaft or
bushings, pull camshaft out of the front of
the engine. Carefully guide rear of shaft
through the journals. If shaft does not come
out freely, ensure all valve lifters are clear of
camshaft cams and journals.
5. Remove valve lifters.
Valve lifters have established wear patterns and
should be reinstalled in same locations. Label
each valve lifter upon removal and place on a
clean work surface.
[212 NP & LQ] PISTON AND
CONNECTING ROD ASSEMBLY
The crankshaft and related components are
heavy, have sharp edges and many possible
pinch points. Always be careful while working
in this area to avoid serious personal injury.
Before removing pistons, connecting rods and
rod caps, ensure they are marked so they can be
reinstalled in the same cylinders from which they
were removed.
Remove connecting rod and piston assemblies in
companion cylinder sets: 1 and 6, 2 and 5, and 3
and 4.
1. Rotate engine stand 90 degrees so that
pistons lie horizontally in the block with top
of pistons and connecting rods accessible.
2. Rotate crankshaft so that pistons 1 and 6
are lowered in the cylinder at least
two inches (51 mm) to allow adequate room
to remove carbon from upper edge of
sleeves.
