6.2.24 Remove the power end- XHD and XHD V
alue Option
Before beginning removal of the power end, check to ensure that the pedestal (131) is securely fastened
to the foundation, baseplate or work surface, such as a workbench.
When removing the power end, the coupling hub or V-belt sheave on the drive end of the shaft must also
be removed.
The power end of the XHD and XHD Value Option models can be removed during traditional liquid end
disassembly when the suction half casing, suction side liner, adjustable seal ring (XHD only), knock off
ring, impeller and gland (packing or mechanical seal) are removed. In this state, the gland half casing
remains attached to the pedestal with the casing volute liner, seal cover and stuffing box still installed.
Proceed as follows:
1. Drain the oil from the bearing cartridge housing (228) by removing the oil drain pipe plugs (408A).

3. Slide the power end backwards away from the liquid end until the shaft is completely free of the
liquid end and pedestal (131) lower half-ring.
4. Remove the outer bearing frame adjustment rod nuts (415A) and threaded rods (370X).
