4.0 MAINTENANCE AND REPAIR
4.1 Air motor section disassembly
1. Follow the Procedure for Pressure Relief (page 5). It is very important to
relieve all air and fluid line pressure as well as pump pressure before
proceeding to the next step or injury can occur.
2. Remove inlet and outlet hoses. Place the pump in a vise or other holding
device. If you know that you just need to work on the air motor, the pump can
simply be left in the drum it is operating in.
3. Clamp on the housing with the outlet hole against one of the jaws of the
vice. When clamping the housing- either the air motor assembly or the
lower tube and/or foot valve can be removed.
Use a strap wrench to remove the air motor assembly.
The pump assembly can be removed from the air motor by disengaging the Piston Rod.
