Product Information

The 4030 Bearing Housing is a component used in pumping units. It includes a shaft bearing (inboard and outboard), lock washer, lock nut, bearing housing, snap ring, cap (outboard), capscrew, hex head key, woodruff, water slinger, adapter, washer, mechanical seal, shaft sleeve, impeller, casing gasket, pipe plug, support foot, nut jam, and washers. It is important to always disconnect the power supply from the motor before beginning service work.

The symptoms of a malfunctioning bearing housing include overheating and low bearing life. Proper lubrication is necessary for optimal performance and the oil should be changed every year or 3000 hours.

Product Usage Instructions

1. Clean the shaft sleeve surface and inspect for damage. Replace if necessary.
2. Make a separate subassembly of the bearing housing, adapter, seal, impeller, and bearing support. Fasten to the bearing housing.
3. Fasten the adapter to the bearing housing.
4. Add the seal to the shaft.
5. Insert the impeller.
6. Fasten the impeller to the shaft using washers and impeller bolts.
7. Add the casing gasket to the casing.
8. Lift the subassembly carefully and fasten it with the casing.
9. Fasten the bearing support to the base.
10. Rotate the shaft and check for misalignment if any.
11. Observe if any undesired noises are coming from the assembly by rotating the shaft.
12. Reconnect power and resume normal operations.

It is important to follow the above procedure and to ensure that the power source to the driver is disconnected, locked off, and tagged before performing any service work. The product should be lubricated properly and the oil should be changed every year or 3000 hours. If you experience any issues or have additional questions, please refer to the contact information provided in the manual.

Caution
Always disconnect power supply from motor before beginning service work.

warning:
Whenever any service work is to be performed on a pumping unit, disconnect the power source to the driver, lock it off and tag with the reason. Any possibility of the unit starting while being serviced must be eliminated.

Assembly Instruction

1. Clean the shaft sleeve surface, ensuring the entire former seal elastomeric residue has been removed. Inspect for damage and replace if necessary. (See separate instructions, file no. 6042.25, for removal of the motor shaft sleeve). Inspect the water slinger and replace it if damaged.
2. Make separate subassembly of bearing housing, Adapter, seal, Impeller, and bearing support & fasten to the bearing housing.
3. Fasten the adapter to the bearing housing.
4. Add the seal to the shaft.
5. Insert impeller.
6. Fasten the impeller to the shaft using a washer & impeller bolt.
7. Add a casing gasket to the casing.
8. Lift the sub carefully & fasten it with the casing.
9. Fasten the bearing support to the base.
10. Rotate the shaft and check for miss alignment if any.
11. Observe if any undesired noises are coming from the assembly by rotating the shaft.
12. Reconnect power and resume normal operations.

Lubrication

Pump

Sealed Grease Bearings

• If the pump is fitted with greased lubricated bearings, no external lubrication is required.
• These bearings are custom greased for general service applications and sealed.

Oil Lubricated Bearings

• If the pump is fitted with oil lubricated bearings; use a non-detergent oil equal to No.10 motor oil.
• Prior to start up check to make sure the oil level is visible in the sight glass.
• Under normal operating conditions the oil should be changed every year or 3000 hours as follows:
  1. Drain the oil from the old bearing bracket.
  2. Thoroughly flush the bearing bracket with Kerosene. 3 Refill the oil through the vent on top of the bracket until the oil level is visible in the middle of the sight glass.
