After the wrist pin bushing has been pressed into the connecting rod, it
must be honed to 1.1263/1.1259. A hydraulic press and honing machine are
recommended for this step.
Never attempt to separate the piston rod and crosshead. When repair
becomes necessary, the entire crosshead assembly must be replaced.
WARNING
CAUTION: Always relieve pressure in the unit before attempting
any repairs.
