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.
