Bearing Housing FA1D56-02-01A-00: Don't Let Removal Ruin Your Booster Pump

Core Rule Before Removal: Take Off Guards First

In power plant maintenance for the FA1D56 booster pump, removing the drive-end bearing housing FA1D56-02-01A-00 is a technical checkpoint. Do it right, and the pump runs steady. Do it wrong, and you get oil leaks and pump vibration. The DL/T 801-2010 standard is clear: before touching the bearing housing, you must remove the coupling disc pack and the guard cover. This step is not a hassle; it's key to safety.

Three Key Reasons to Remove Guards First

• Dongfang SRI designed this bearing housing to be tight and precise. The housing bolts, locating pins, and coupling are extremely close. If you try to remove the housing without taking off the coupling, the wrench often gets stuck in the small gap.
• The bigger risk is part damage. The bearing housing's face seal and locating surface are machined to micron precision. If you move the bearing housing with the coupling discs still attached, metal-on-metal collision can cause scratches. A damaged seal face means an oil leak next time it runs. A warped coupling disc pack doubles vibration during transmission.
• Safety is non-negotiable. The guard cover blocks your view. When removing bolts, you can't see the stress point clearly. Tools can spring back and hit your hand. Follow the rule—remove the guards first—and you avoid these risks.

Skip the Rules? These Risks Are Guaranteed

The cost of skipping the rules is high. Forcing removal can deform the bearing housing. When reassembling, it won't meet the 0.025mm concentricity standard. The pump will vibrate wildly when it runs. Its lifespan is cut in half. If you use our compliant spare parts and follow the steps, these problems are preventable.
