Check List
1. Lubrication - J and S Frames
J Frame - J frame pumps have a greased-for-life ball bearing. No additional lubrication is required.
S Frame - S frame pumps have ball bearings which are greased at the factory.
Bearings should be regreased every 2000-3000 hours (3-4 months).
To regrease bearings:
1. Remove plug on top of bearing frame. Screw in Alemite grease fitting included in the box
fittings, shipped with the pump.
2. Add grease while turning shaft by hand until old grease is forced out of grease relief fitting at
bottom of bearing cap and fresh grease appears.
3. Remove grease fitting and reinstall plug.
2. Lubrication M, L, X and Y Frames
M, L, X and Y frames have flood oil lubricated bearings. The bearings are not lubricated at the fac-
tory. A constant level oiler, #5 TRICO, is packed with the pump.
a) Before installing the oiler on the bearing frame, check the oiler adjustment. The setting dimen-
sion 14.3 mm | 0.56" is illustrated in Figure: Dimensional checks .
b) Remove the small plastic plug from the large pipe plug on the left side of frame as viewed from
the motor end of the pump.
NOTICE:
The Y frame has a ¼-18 NPT tapped hole.
c) The nipple-elbow assembly is assembled finger-tight at the factory. Before
installing it on pump, the threaded connections should be made up with pipe sealant.
NOTICE:
The oiler may be installed on the right side of the pump (viewed from motor end) by moving the
2"-11½ NPT plug with ¼"-18 NPT tapped hole to right side and assembling as above.
d) Install the nipple-elbow assembly so that the long nipple (¼ NPT x 44mm | 1.75" long) extends
horizontally from the frame to the 90 degree elbow and the close nipple vertically from the el-
bow to the bottom connection of the oiler. Refer to
Figure 2: Dimensional checks on page 15 .
If oil level is too high (splashes out of breather), lower level 1.5mm | 0.06" at a time until splashing
stops.
