8. Turn the inner threaded adjustment rod hex nuts (415A) until in place against the inner
surfaces of the outboard bearing end cover (109) and adjustment plate (234F) ears.
Assembly of other power end configurations
The assembly of other available power end configurations is very similar to that of the XHD oil
lubricated 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 lubrication or isolators used.
The following subsections highlight the main differences in the assembly of power end
configurations other than the XHD oil lubricated power end.
Assemble the power end - XHD, grease lubrication, isolators
• Regardless of the type of lubrication, the XHD power end uses labyrinth seals as bearing
isolators. Assembling 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 (346A), as shown on the figures below.
Figure 107: Bearing assembly
• There are also grease fitting plugs (319H) and grease relief plugs (319Y) installed into the
bearing cartridge housing (228) used for purging and regreasing the grease lubricated
XHD XL power end.
• There will be no sight glass (319) or opposite sight glass (408N) on the grease lubricated
power end
