Cylinder / Piston Installation

CAUTION
Pistons must be installed into the cylinders with the
connecting rods attached.
DO NOT attempt to service the cylinder or pistons
without disassembling the crankcase. Although you can
remove the cylinder and pistons without disassembly,
you will not be able to reassemble the engine because
of the unique cylinder skirt and crankcase design.
NOTE: If the pistons are being reused, reassemble
in the same cylinder bore and direction from which
they were removed (MAG / PTO).
New pistons are directional (intake vs. exhaust), but
can be placed in either cylinder.
1. Apply clean engine oil to each piston assembly,
cylinder bore and bottom tapered portion of each
cylinder sleeve.
2. Verify that all ring end gaps are correctly located on
each piston (see Chapter 3 –
Installation, page 3.64).
3. Note the piston orientation mark (arrow) located on
top of the piston. Arrow should point toward the
exhaust side.
NOTE: Orientation arrow is also located on the
bottom side of piston as an additional reference.
