caution when installing the connecting rod assembly in the pump is to make certain the oil holes in the rod are “UP” and not toward
the bottom of the pump. This will result in lubrication failure in these parts and the pump will fail in a short period of time. An
additionally important step is to make sure that the rod cap is bolted back on the rod as it came off. The rod and cap carry a “mark”
or “number” which allows you to match them back properly. Failure to do this will cause the rod not to fit the journal for which it was
made.
H. Power End/Fluid End Connection: A common misconception is that there is some form of fluid seal between the power end and the fluid
end. This is false. The fluid end is merely bolted to the power frame. It can be removed by breaking the plunger connection, backing off the
packing nut or gland, removing the various fluid end bolts, and sliding the entire fluid end off the power frame. Corrosion may tend to seize
the two components together making their separation difficult in some isolated cases. On models KP ‐ 3300, KT ‐ 3350/KT ‐ 3400 and R335/R340
the bolted in stuffing box assemblies must be removed prior to removal of the entire fluid end. They are held in place by four studs each. On
all other units the stuffing boxes can be left intact. On the remaining pumps (with the exception KD ‐ 1250B, KJ ‐ 2250B, KM ‐ 3250B, and KCP ‐
6300) the stuffing boxes are held in place in the fluid end by a friction or “press” fit. They should be removed with a hydraulic press if
possible. These press ‐ in type stuffing boxes carry a gasket and/or an o ‐ ring to insure a good seal. The boxes on the KD ‐ 1250B, KJ ‐ 2250B, KM ‐
3250B, and KCP ‐ 6300 are screw ‐ in type and carry only a copper gasket.
