12. Obtain the Piston Ring Compressor (see SECTION 3 -
TROUBLESHOOTING - Special Tool List ), and proceed
as follows:
A. Using tool wrench, unwind sleeve of piston ring
compressor. Do not unwind sleeve too far or tool
damage will occur.
B. Apply clean engine oil to piston rings, piston
skirt, cylinder bore, and inside wall of Piston Ring
Compressor.
C. Slide compressor sleeve over piston, and using tool
wrench, tighten to compress piston rings into piston
ring grooves.
D. Verify that all piston rings are captured and
compressed, but that compressor sleeve is still loose
enough to be rotated.
E. Gently tap on the top edge of the compressor sleeve
to be sure the bottom edge is in full contact with
cylinder deck.
F. Apply steady pressure to piston crown to slide piston
from compressor sleeve into cylinder bore.
NOTE: Do not hammer piston into cylinder bore or piston
rings may be damaged. If piston travel is stopped before it
completely enters the cylinder bore, then retract the piston,
reset the piston ring compressor sleeve, and try again.
13. See Figure 149. With connecting rod positioned on crank
pin journal, install connecting rod cap, so that the match
marks on cap and connecting rod are aligned.
