Removing The Connecting Rods - Weatherford MP-16 Operation & Maintenance Manual

5.2.6 Removing the Connecting Rods

The connecting rods should only be removed if absolutely necessary. If it is necessary to
remove multiple connecting rods, each rod should be stored separately to avoid confusion.
Remove the main bearings as per 5.2.5,
1
and support the crankshaft assembly so that
the load is not resting on the connecting
rods.
Unbolt and remove the outer bearing
2
retainer from the crankshaft.
Carefully slide the connecting rod off of the
3
crankshaft. Note that the outer race of the
crankpin bearing will remain attached to the
connecting rod, exposing the rollers, so care
should be exercised to avoid potential
damage to the crankpin bearing.
