ROUTINE MAINTENANCE & SERVICE INSTRUCTIONS
FIGURE 8 – JACKSHAFT ASSEMBLY
Daily Care – The pump should be kept clean, lubri-
cated properly and stuffing boxes examined daily. With
reasonable care, the pump can be expected to give
long and trouble–free life.
Occasional Inspection – It is recommended that the
fluid valves be examined occasionally to see that ex-
cessive wear or cutting has not impaired their efficiency
and any damaged or worn parts should be replaced.
Fluid end must always be drained when exposed to
freezing weather during idle periods.
SERVICE INSTRUCTIONS
Removal of Jackshaft – To remove the jackshaft, it is
necessary to remove the bearing housings from both
sides of the pump. The bearing outer races and rollers
come off with the housings. The bearings inner races
and the seal bushings are pressed on the jackshaft and
need not be removed unless replacement is necessary.
The jackshaft can be lifted clear of the gear teeth and
removed. The jackshaft is not interchangeable end for
end, hence, it must be reinstalled in the same way it
was removed.
Installation of Jackshaft Oil Seals – The jackshaft
roller bearings are provided with a separate inner and
outer oil seal. The correct assembly of these seals is
with seal lips facing bearings.
To Remove Crosshead Pin From FXF and FXG
Pumps – The crosshead pin can be removed from the
FXF and FXG only by removing the entire gear assem-
bly. To remove the gear and eccentric, it is necessary
to remove the main shaft. The main shaft must be re-
moved from the side of the pump in which the end of the
shaft contains a 3/4–10 UNC tapped hole. This is the
end of the shaft that also contains the main shaft to ec-
centric key. (See FIGURE 9.) It is advisable to have
new shaft seals as these seals can rarely be used the
