 TM 55-1905-223-24-1
CAUTION
The connecting rods and caps are not
interchangeable. Failure will result if they are
mixed.
The bearings in the same rod and cap must have
the same part number. If the part numbers are not
the same, the bearings will fail and cause severe
engine damage.
(4) Install bearing (4, FIG. 3-22) in connecting rod cap (5). Align bearing oil hole with cap oil hole.
Lubricate bearing with clean engine lube oil.
(5) Lubricate the connecting rod machine bolt threads and beneath the bolt head with clean engine
lube oil.
(6) Lubricate the entire cylinder liner with clean engine lube oil.
(7) Immerse the piston in lube oil until the rings are covered. Allow excess oil to drip from pistons.
CAUTION
Ring damage may result from improper use of the ring
compressor. If a band-type compressor is used, be sure
the inner band does not slip and bind the piston. The
rings should pass into the liner smoothly. Ensure rings
are staggered.
NOTE
The ring compressor has a tapered bore. The small end
of the taper must be toward the piston skirt.
(8) Install piston ring compressor on piston.
CAUTION
The connecting rod must be installed so that the
chamfer on the rod is toward the fillet radius on the
crankshaft rod journal. If the rod is reversed, the
crankshaft will be damaged (FIG. 3-24).
