(l) Removing connecting rod cap
(a) Remove the nuts that hold the cap to the
connecting rod. Tap the bolts squarely and
evenly with a hammer and, after the cap
comes off the reamer bolts, remove the cap.
(b) Mark the bearings for cylinder number and
location.
(2) Preparation before removing pistons
(a) Lay the crankcase on its side.
(b) Use a cloth or oil paper to remove all carbon
deposits from the upper areas of the cylinder
liner. If any carbon deposits are present, this
will make it difficult to pull a piston upward.
(3) Removing piston
(a) Turn the crankshaft to bring the piston (from
which the connecting rod cap has been
removed) to top dead center.
(b) Put the handle of a hammer on the big-end of
the connecting rod and push the piston
assembly off the cylinder.
(4) Removing piston rings
Use piston ring pliers (31391-12900) to remove
the piston rings.
