Remove the power end- XHD and XHD Value 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).

2. Loosen the power end adjustment plate bolts (352G) and nuts (427D) but do not remove.
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.
