C-30HD — SERVICE INFORMATION: BEARING INSTALLATION

After the cam bushing is installed as per instructions below, remove the three “dog type” allen set screws (B) to allow detents to be drilled. Use a 9/32” drill to “detent” half (minimum 1/8” deep). Then “chase” the threads with a 3/8-16 bottom tap and blow out the chips after drilling, to be certain that the “dog type” allen set screws bottom in the detents to prevent the taper bushing from sliding laterally. If this procedure is not followed closely the heavy loading of the bearing during pumping operations causes the Timken cone bearings to create lateral forces which will move the taper bushing and allow the Timken cone bearings to separate from the race and subsequently fail.

Caution: Position the ‘O’ ring on the O.D. of the bearing spacer during assembly to assure proper bearing adjustment.

Note: It is important that the bearing assembly is installed properly.

1.Install the bearing components on the crankshaft making full contact with the back side of the crank disc as indicated by the symbol*.

2.Install the bushing in the cam weldment and slide it onto the crankshaft until contact is made with the bearing spacer.

3.Tighten the 3 allen socket head screws “A” while exerting pressure on the bushing towards the bearing spacer.

4.Drill (detent) the shaft under the allen set screws “B” to prevent the bushing from the sliding away from the bearning spacer when the pump is under a load.
