3-62 2007 Buell Lightning: Engine

HOME

NOTE

Handle the piston with extreme care. The alloy used in these

pistons is very hard. Any scratches, gouges or other marks in

the piston could score the cylinder during engine operation

and cause engine damage.

8. See Figure 3-86. Remove the piston pin circlip as fol-

lows:

a. Insert the PISTON PIN CIRCLIP REMOVER/

INSTALLER (Part No. HD-34623C) into the piston

pin bore until claw on tool is positioned in slot of pis-

ton (directly under circlip).

b. Squeeze the handles of the tool together and pull

from bore. In the event that the circlip should ﬂy out,

hold a shop towel over the bore during removal.

Remove circlip from claw and discard.

NOTES

● It is not necessary to remove both piston pin circlips dur-

ing piston removal. Leave the second circlip in the pin

bore.

● Since the piston pin is a loose ﬁt in the piston, the pin will

easily slide out. The pin has tapered ends to help seat

the round retaining rings.

NOTE

See Figure 3-87. The arrows at the top of piston must always

point toward the front of the engine.

9. See Figure 3-88. To remove piston rings spread outward

until they clear grooves in piston and lift off.
