Disassembly Notes
• Do not disassemble pump for repair unless test
procedures indicate internal leakage.
• Never pry components apart. Use a soft face
hammer, and gently tap housing and shaft to
separate pump bodies.
• Scribe or mark the pump bodies and end covers
before disassembly to aid in assembly.
Recommended method of marking body sections is
to use a fine point metal punch, making one
indentation for section #1, two indentations for
section #2, etc.
