Install Piston to Connecting Rod

Connecting Rod Fastener Torque Sequence

NOTE: Proper orientation of piston/connecting rod
inside engine is extremely important. Improper
orientation can cause extensive wear or
damage.
1. If piston rings were removed, see Disassembly/
Inspection and Service procedure to install rings.
2. Lubricate cylinder bore, crankshaft journal,
connecting rod journal, piston, and rings with engine
oil.
3. Compress piston rings using a piston ring
compressor. Orient FLY mark on piston toward
fl ywheel side of crankcase. Place ring compressor
on top surface of crankcase and make certain it is
seated down around entire circumference. Use a
soft, rubber grip hammer handle and tap piston/
connecting rod into bore. First tap should be rather
fi rm, so oil ring moves from compressor into bore in
one smooth, quick motion. Otherwise oil ring rails
may spring out and jam between ring compressor
and top of bore.

5. Install screws and torque in 2 increments, in
sequence shown, fi rst to 5.5 N·m (50 in. lb.), fi nally
to 11.8 N·m (105 in. lb.).
