second time. Remove shaft through eccentric with
hammer and wood block and the bearing cone and seal
bushing on the side opposite the tapped hole will slip off
the shaft.
The gear assembly with connecting rods and cross-
heads can all be pulled out through the hood opening
after the main shaft has been removed. The piston rods
of course must be screwed out of the crossheads be-
fore the assembly can be taken from the frame. Cross-
head pins are straight and are held in place in the cross-
heads with set screws.
To Remove Crosshead Pin From FXX, FXD and
FXE Pumps – The inspection plates on the sides of the
frame should be removed. Two hexagon head cap
screws are used to hold the crosshead pin to the cross-
head. These are the two screws in the corners of the
plate over the crosshead pin. Take these screws out
and insert them in the tapped holes in the adjacent cor-
ners of the plate and by exerting sufficient pressure
with these screws the crosshead pin will come out. A
little persuasion with a drift driven against the cross-
head near the outer end of the crosshead pin will help.
To remove the gear and eccentric it is necessary to re-
move the main shaft and piston rods. The main shaft
must be removed from the side of the pump in which 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, page 12.) Support eccen-
tric on blocking and drive shaft through eccentric with
hammer and wood block. The bearing cone and seal
sleeve, on the side opposite the tapped hole, will slip off
the shaft.
To Install Main Bearings For All Pumps –
1.
Install eccentric with gear teeth in correct position
in frame.
2.
Install main shaft through opening in frame and
through eccentric.
3.
Heat and press bearing cones to shaft.
4.
Install bearing cups.
There should be no space between
the bearing cones and seal bushing
or between the seal bushing and ec-
centric hub.
5.
Install gasket and end plate on one side.
6.
Take up end plate on other side snugly with cap
screws.
7.
Check the gap between plate and frame housing
with shims. Determine shims required to fill the
gap. When you have determined the shims re-
quired to fill the gap, remove 0.001 to 0.003 inches
(0.0254 to 0.0762 mm) of shims.
8.
Remove end plate and install remaining shims.
9.
Mount and secure plate.
FXE Main Gear and Eccentric – This pump is
constructed with a separate gear bolted to the eccen-
tric. Refer to page 18 for screw torque specifications.
MAINTENANCE OF SPARE REPAIR PARTS – Al-
though operating conditions vary widely, it is suggested
that a stock of spare replacement parts be maintained
to insure against loss of pump operation. It is consid-
ered good practice to keep spare fluid valves, pistons,
piston rods, packings, gaskets, etc. on hand. A recom-
mended list of such parts may be secured from Gard-
ner Denver Customer Service, the Master Distribution
Center (MDC), or your local authorized Gardner Den-
ver Distributor.
ORDERING OF REPAIR PARTS – Repair parts lists
with sectional views are available for any Gardner Den-
ver
power pump and may be secured from Gardner
Denver Customer Service, the Master Distribution
Center (MDC), or your local authorized Gardner Den-
ver Distributor.
