DISASSEMBLY
The numbers used in the following procedures are part
numbers identified on the Pump Assembly Pix drawing.
Use acceptable mechanical practices when working on
pump to avoid unnecessary damage to parts.
1. Disconnect coupling. Refer to coupling manufacturer's
instructions.
2. Drain pump by opening vent plug and removing drain
plug on discharge and suction nozzles.
3. Remove gland bolts, slide gland plates (107) away to
disconnect mechanical seal faces.
4. Remove all casing main joint nuts and dowels. Use
jacking screws in two tapped holes to break joint. Lift
casing cover by cast lugs.
5. Gasket
A strong Garlock 3000 gasket is placed between the
pump half casings at the factory. The gasket may be
readily replaced, when necessary, with the same or
similar material of the same thickness as original and
cut to proper shape. Heavier gaskets must not be used,
as they hold the casing apart allowing leakage around
the wearing rings. A lighter gasket will place undue
stress on the casing rings.
6. Remove bolting holding bearing housings caps to
bearing housings (134D). Mark the caps to know to
what end they belong. Lift up the caps. The entire
rotating element may now be lifted out.
7. Pull coupling half and key off shaft. Remove bearing
end plate (111).
8. Remove both casing rings (127).
9. Remove radial bearing (168).
10. Remove locknut and lockwasher (136 & 382) and pull
off thrust bearing (410).
11. Remove bearing endplates and bearing seals (333A &
332A).
