11-8
Any ridge on the
cylinder must be
removed with an
automotive type
ridge reamer before
removing the left
side pistons.
Remove the bearing cap nuts and bearing caps on
the left side connecting rods.
Push the piston/connecting rod assemblies out
through the top of the left cylinder bores (No. 2, 4
and 6).
PISTON/PISTON RING REMOVAL
Do not damage the
piston ring by
spreading the ends
too far.
Spread each piston ring and remove it by lifting up
at a point opposite the gap.
Never use a wire
brush; it will scratch
the groove.
Clean carbon deposits from the ring grooves with a
used piston ring that will be discarded. Never use a
wire brush; it will scratch the groove.
PISTON INSPECTION
Inspect the piston rings for movement by rotating
the rings. The rings should be able to move in their
grooves without catching.
Push the ring until the outer surface of the piston
ring is nearly flush with the piston and measure the
ring-to-ring groove clearance.
