Mechanical End Disassembly
GIW REGEN Service Centers remanufacture bearing assemblies and refurbish pumps.
GIW will rebuild your assembly and return it to its original specifications using genuine OEM replacement parts.
Contact your GIW / KSB Sales Representative for details.
WARNING
Refer to Section 2.9 "Assembly & Disassembly Safety" prior to working on the pump.
Separate the bearing housing from the mounting plate and impeller.
Remove the flingers (if any) and bearing housing end covers. Care should be taken with the Inpro oil seals, which
should not be removed from the end covers unless they have been damaged and are in need of replacement. Inspect
the seals, gaskets, and o-rings, and discard any that appear worn or broken.
The shaft and bearings (which are pressed onto the shaft) may then be removed as a unit from the drive end of the
housing. Horizontal disassembly is acceptable when proper support is given to the shaft to prevent its contacting and
marring any of the finished surfaces of the shaft or bearing housing bore. Care should be taken to avoid damaging the
grease retaining ring (part 63-7, grease lubricated) or spacer ring (part 45-4, oil lubricated) that will come out on the
shaft between the two bearings.
Remove the drive end bearing assembly to expose the thrust bearings. The locknut and lock washer that clamp the
drive side bearing should also be removed. One tab of the lock washer will be bent into a recess on the lock ring and
must be bent back to allow the lock nut to be unscrewed.
The bearings are hot when installed on the shaft, and fit tight. It is difficult to remove them from the shaft undamaged,
and they should be removed only if a bearing needs to be replaced. Bearings are normally removed by heating, which
should be done quickly to prevent heating of the shaft as well. Flame cutting of the outer race and careful grinding of
the inner race may occasionally be required. Care must be taken, however, to avoid damaging the shaft, especially in
the oil seal area.

Mechanical End Assembly
WARNING
Refer to Section 2.9 "Assembly & Disassembly Safety" prior to working on the pump.
CAUTION
Before assembly, thoroughly clean all shaft, housing bore, and end cover surfaces with a suitable solvent to
remove old grease and any water, dust or grit. Clean all dismantled components and check them for signs of
wear. Damaged or worn components are to be replaced by original equipment spare parts. Make sure that the
seal faces are clean and the O-rings and gaskets are properly fitted.
