WSG-1068 GENERAL INFORMATION
Piston Ring-to-Groove Clearance
Special Tool(s)
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.
