Figure 4.4 Removal of the liquid end from the isolator
The liquid end body should be allowed free access through the cutout at the bottom of the
base plate. The isolator bearing (10) will come out with the liquid end body. A sliding hammer
movement of the pump head on the piston may be necessary to pull out the isolator bearing.
Removing the Piston, Bearing Retainer and Bearing
1.
To remove the bearing retainer, first place the liquid end body in a vise. It is
recommended that the vise teeth be made of brass. If brass is not available, wrap the
liquid end body in a rag or cloth so that the vise teeth do not scratch or damage the liquid
end body.
2.
Wipe clean any debris or liquid around the piston (2) and retainer area.
3.
Pull the piston outwards to allow access to the bearing retainer (10).
NOTE:
The piston may not come out completely.
4.
Obtain the bearing retainer removal tool MFIC Inv. #801.13470.
5.
Place the dowel pins into the bearing retainer slots and rotate the removal tool in a
counterclockwise direction. Refer to Figure 4.5.
