BRACKET 2973214 - Caterpillar

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) .
Install Tooling (E) into shaft assembly (36). Install Tooling (D) onto the pump housing. Use Tooling (D) to determine the end play of shaft (36). Be sure that you move shaft (36) completely in both directions. Use appropriate tools to move shaft (36).
If necessary, grind the adjustment shim to obtain the correct dimension between the head assembly and the main drive pump housing. If necessary, replace the shim with a new part.
The thickness of the shim 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.
Remove the head assembly from the main drive pump housing. Remove the bearing cone and the adjustment shim from the shaft assembly.
Proceed with the assembly of the main hydraulic pump.
