12. Inspect the following parts carefully for deep grooves, scratches or other damage:
•
The I.D. surface of the housing.
•
The back face of the rotor.
•
The back face of the housing bushing.
•
The O.D. of the rotor.
13. Inspect the bushings in the housing for wear.
14. Do not remove the o-ring from the housing unless it is worn or damaged and needs
replacement.
Section 12: Pump Disassembly Procedure - 6200 Pumps
Refer to Figure 5.
Although some minor disassembly is possible with the complete pump/motor assembly still in
place, it is recommended that the pump/motor unit be disconnected and moved to a maintenance
area.
! WARNING
Residual pumped fluid will be present in the pump. Follow all precautions outlined in the Material
Safety Data Sheet (MSDS) applicable to the liquid being pumped to ensure safe handling.
1. Remove piping from the ports.
2. Mark cover, housing and bracket before disassembly to ensure proper reassembly.
3. Remove the cover screws, cover, housing and idler.
4. Inspect the following parts carefully for deep grooves, scratches or other damage:
•
The I.D. of the housing.
•
The end face of the rotor.
•
The O.D. of the rotor.
•
The O.D. of the idler.
•
The I.D. of the idler.
•
Both faces of the idler.
•
The O.D. of the idler pin.
•
The inside surfaces of the cover including the crescent.
5. Check for signs of wear. A decrease in capacity is generally caused by the abrasive action of
foreign materials in the liquid, resulting in excessive end clearances. End clearance can be
reduced by changing to a thinner cover gasket. To adjust the end clearance, see assembly
procedure.
