'1. Using a piston, push a new ring into the cylinderbore 15 - 20 mm (0.6 0.8 in) from the boftom.
Measure the piston ring end-gap with a feelergauge:
lf the gap is too small. check to see if you have
the proper rings for your engine.
lf the gap is too large, recheck the cylinder bore
diameter against the wear limits on page 7-13.
ll the bore is over the service limit, the cylinder
block must be rebored.

Connecting Rods
Selection
Each rod falls into one of four tolerance ranges (from 0
to + 0.024 mm (0 to + 0.0009 inl, in 0.006 mm {0.0002 in)
increments) depending on the size ot its big end bore.
It's then stamped with a number (1,2,3, or 4) indicating
the range.
You may find any combination ol 1, 2, 3, or 4 in any
engane.

NOTE:
a Reference numbers are Jor big end bore size and do
NOT indicate the position of the rod in the engine.
. Inspect connecting rod for cracks and heat damage.

lnstallation
Before installing the crankshaft. apply a coat ofengine oil to the main bearings and rod bearings.
1. Install the thrust washers in the No. 4 iournsl of the
cvlinder block.

Insert bearing halves in the engine block and con-
necting rods.
Hold the crankshaft so rod journals for cylinders No.

Lower the crankshaft into the block. putting the rod
journals into connecting rods No.2 and No.3.
Install the rod caps and nuts finger-tight,

9. Apply non-hardening liquid gasket to the block mat-
ing surface of the right side cover, and install it on
the cylinder block,
NOTE:
. Use liquid gasket, Part No. 08718 - 0001.
. Check that the mating surfaces are clean and dry
before applying liquid gasket.
. Apply liquid gasket as an even bead, centered
between the edges of the mating surface.
. To prevent leakage of oil, apply liquid gasket to
the inner threads of the bolt holes.
. Do not install the parts if 20 minutes or more
have elapsed since applying the liquid gasket.
Instead, reapply liquid gasket after removing the
old residue.
. After assembly, wait at least 20 minutes before
filling the engine with oil.
