15. Bearing cones (22) may be removed
from the crankshaft using an
automotive type bearing puller.
Bearing cups (23) can be removed
from the bearing housing using a
puller if a sufficient lip is available for
the puller arms to grab. An alternate
procedure involves running a weld
bead around the inside surface of the
cup. When cool, this will reduce the
interference between the cup and
bearing housing enough to free the
cup. If either the cup or cone is
replaced, the corresponding cup or cone should be replaced as they are a
matched set.
16. Pull the connecting rod/crosshead
assemblies (7) from the power frame.
Mark each connecting rod and
crosshead assembly to insure they
are reassembled into the same bore
from which they were removed.
17. Remove the set screw (27) and slide the wrist pin (6) out of the crosshead (7) if
crosshead or connecting rod (4) requires service. Keep components matched
together.
18. Inspect all components for signs of wear or damage and replace if required.
Carefully check the crankshaft bearing surfaces for pits, scratches, or other signs
of wear. The connecting rod bearings should be inspected for deep scratches or
the top metal surface worn away.
19. If damaged, remove the crankshaft oil seal (19) using a screwdriver or similar
object and discard the old seal.
20. Thoroughly clean all parts with solvent and apply a thin coat of oil before
reassembly.
21. Tapered roller bearing cones (22) must be heated to aid in assembly onto the
shaft. Always observe proper safety procedures and use heat resistant tools and
gloves when handling hot parts. There are a number of recommended methods
for heating bearings. Electric ovens or electrically heated oil baths may be used,
but only when accompanied by proper thermostatic control.
