Maintenance
Disassembly
1. Loosen the setscrew and remove the coupling half (item 2) from the end of the pump shaft.
2. Carefully holding the intake tube (so as not to crush the tube), use a 3/8” punch and hammer to drive the
bottom of the pump shaft (item 10) up through the intake tube (item 7) until the bearing assembly (item 3) is
completely exposed.
3. Use a 1/8” punch to remove the roll pin that holds the bearing assembly (item 3) onto the pump shaft, and
remove the bearing assembly.
4. Remove the setscrew (item 13) from the bottom of the intake tube and remove the bottom bearing (item 12).
5. Now drive the shaft assembly back down through the intake tube and remove it from the bottom. Remove
and discard the seal assembly (item 4) from the top of the pump head.
Inspection
1. Inspect the bottom bearing for damage or wear (if ID is .400 or larger) and replace as needed.
2. Visually inspect the compressors (item 8) for damage or wear and replace as needed.
