Section 5
DISASSEMBLY
Disassemble Connecting Rods, Pistons and Rings
as follows:
1.
Remove the piston rings (3, 4 and 5, Fig. 7) with
a piston ring expander. Remove the top
compression ring first then the remaining rings in
order.
2.
Remove the piston pin retainers (2) from each
piston.
3.
Remove the piston pin (1) by hand.
NOTE: Do not apply excessive force to the piston
pin. It is recommended that the piston be heated in
water to 71°-82°C (160°-180° F) if the pin cannot be
removed by hand when cold.
4.
After the pin is removed, seperate the piston (6)
from the connecting rod (7). Tag or mark the
piston and parts with the number of the bore
from which they were taken, so they may be
reinstalled in their respective cylinders once
inspected and/or repaired.
5.
Remove connecting rod piston pin bushing (7,
Fig. 1) using a suitable arbor press. Discard old
bushing and replace with new. Refer to
"REASSEMBLY" this section.
