3. Measuro the piston pin-to-piston clearance.
NOTE: Check the Diston for distonion or cracks.
It the piston pin clearance is greater than 0.022 mm(0,0009 in), remeasure using an ovorsize piston pin.

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.

Rotate the crankshaft clockwise, put journals into
connecting rods No. 1 and No. 4, and install the rod
caps and nuts finge.-tight.
NOTE: lnstall caps so the bearing recess is on the
samg side as the .ecess in the rod.
Check rod bearing clsarance with plastigage (see

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.
