information on page 52 while
performing this procedure.
1. Remove the pump assembly by performing the
Pump Removal and Replacement
procedure on
page 42.
2. Remove the remaining sheet-metal shrouds from

3. Remove the coupling nut (104), which attaches the
pump to the air motor. Be careful not to lose the
collar couplings (105).
