Crankcase Disassembly (Upper)
1. Remove the oil passage connecting tube (F) with O-rings.
2. Note connecting rod and cap marks so they can be oriented
properly and assembled in the same manner as matched sets
on proper rod journal (G). New rods can be installed with
marks to front or rear. Rods have no offset.
Piston / Connecting Rod Removal
1. Some pistons may have an orientation marking. Note the
arrow (A) should face the MAG end of crankshaft.
NOTE: Replacement pistons can be installed in
either orientation as they are symmetric.
2. Push connecting rod / piston assembly out through top of
cylinder bore of upper crankcase.
NOTE: If pistons are to be reused, mark them for
assembly in same cylinder.
3. See “Piston / Piston Ring Inspection” on page 5.48
