6.2.26 Disassembly of other power end configurations
The disassembly of other available power end configurations is very similar to that of the XHD oil-lubri-
cated power end. All of the major pieces of the power end (bearing cartridge, end covers, bearings, etc.)
are designed for use with all options so only a few components will change regardless of the type of lu-
brication or isolators used.
The following subsections highlight the main differences in the disassembly of power end configurations
other than the XHD oil-lubricated power end.
Disassemble the power end XHD, grease lubrication
•
Regardless of the type of lubrication, the XHD power end uses labyrinth (Inpro) seals as bearing
isolators. Disassembly of the end covers and isolators will follow the same procedure as that of the
XHD oil-lubricated version.
•
The only major difference between oil and grease lubricated power ends for the XHD is the use of
grease shields, as shown on the figure below. During disassembly these can be removed, inspect-
ed and replaced as necessary.
