When properly installed a spring load can be felt when pushing against the cylinder block (refer to Fig. 54, 55,
Set the pump vertically and install the spacer into the center bore of the cylinder block (refer to Fig. 57).
The tapered bearing should be installed with an arbor type press for the most satisfactory results. This bearing
cannot be driven onto the shaft due to the internal spring loading of the cylinder block and shaft. Press on the
inner race of the bearing and use care not to damage roller cage (refer to Fig. 58).
An alternate method of installing this bearing is to use the bearing puller bar and press the bearing onto the
shaft with the center screw of the puller bar. A spacer must be used between the center screw and the bearing
(refer to Fig. 59).
The bearing must be pressed on until it rests on the shoulder of the shaft to insure adequate bearing clearance
(refer to Fig. 60).
