Set bearing preload before you install the rotating group. The bearing preload should be 0.00 to 0.05 mm (0.000 to 0.002 inch) .Note: The bearing cup must be installed to check the bearing preload.
Do not install shim (10). Install bearing cone (7) onto shaft (8). Assemble the pump without shim (10) to check the preload of bearing cone (7).
Install port block (2) on pump housing (1). Install bolts (3).
Install Tooling (D) onto the pump housing. Use the dial indicator to determine the end play of shaft (8). Be sure that you move shaft (8) completely in both directions. Use appropriate tools to move shaft (8).
The thickness of shim (10) found in Step 17 should equal the end play measurement plus 0.0508 mm (0.00200 inch). For example, if the end play is 2.1590 mm (0.08500 inch) then the shim thickness should be 2.2098 mm (0.08700 inch).
Record the measurement.
If necessary, grind the shim to the determined measurement.
