Piston Ring-to-Groove Clearance
1. Inspect for a stop in the grooves.
2. Measure the piston-to-groove clearance.
Crankshaft Connecting Rod Journal
Diameter
• Measure the crankshaft connecting rod journal
diameters in at least two directions perpendicular to
one another. The difference between the
measurements is the out-of-round. Verify the journal
is within the wear limit specification.
Crankshaft Connecting Rod Journal Taper
• Measure the crankshaft rod journal diameters in two
directions perpendicular to one another at each end
of the connecting rod journal. The difference in the
measurements from one end to the other is the
taper. Verify measurement is within the wear limit.
Connecting Rod Cleaning
CAUTION: Do not use a caustic cleaning solution or
damage to connecting rods can occur.
NOTE: The connecting rod large end is mechanically
split or cracked to produce a unique parting face. This
produces a locking joint. Parts are not interchangeable.
• Mark and separate the parts and clean with solvent.
Clean the oil passages.
