Review WARNING ! note on pape 68 before beginning any service
operation.
1. First, review preceding Section “Before You Begin...” on page 67.
Note: Before beginning the removal process, you may want to make sketch (or
photograph) the plumbing and component configuration to aid in re-assembly.
2. Remove necessary body panels and framework to gain access to the
pump compartment and pump and gearbox assembly. Make sure there
is sufficient clearance above the apparatus to lift the pump and gearbox
assembly out of the apparatus.

would interfere with pump removal.
Have clean disposable shop rags and oil dry handy. Also disconnect
cooling tubes from the water manifold and pump, air lines, electrical
switches and tachometer cable as needed.
