2. Coat the piston rings with engine oil, then position
the ring gaps as shown:
A – Joint of coil spring
B – Gap of top compression ring
C – Gap of second compression ring
D – Gap of oil ring
3. Hold the compression ring portion of the piston,
and carefully insert the piston into the cylinder
liner.
NOTE! Do not pinch your fingers between the oil ring
and cylinder liner.
Insert the piston slowly not to damage the oil ring.
4. Coat the rings with engine oil and clamp them,
using the Piston installer. Coat the inside surface
of the installer with engine oil.
5. Lightly tap on the piston head with a soft-head
mallet to insert the piston into the cylinder liner. If
the piston will not go into the liner, move the large
end of the connecting rod back and forth through
the crankcase inspection hole.
6. Make sure that the upper shell of the bearing is
properly positioned in the big end of the connect-
ing rod.
Installing connecting rod cap bolts
1. Place the connecting rod bearing on the connect-
ing rod, fitting its lug in the lug groove. Coat the
threads of the cap bolts and the inside surface of
the lower shells of the connecting rod bearing
with engine oil.
2. Install each cap in position. Hold the upper end of
the cap, then tighten the bolt at the lower end
first. This will help prevent the cap from dropping
into the oil pan. Coat the threads and bearing sur-
faces of the bolts with engine oil, then tighten the
bolts temporarily.
