6.4.12 Disassemble the power end
This procedure explains how to disassemble a standard ring-oil or optional purge-oil mist-lubricated pow-
er end and includes information for the disassembly of these optional features:
•
Pure oil-mist-lubricated power end

CAUTION:
Do not remove bearings from the shaft unless you need to replace them.
