Repair and Re-metalling of Driving end (DE) Thrust bearing and Rebabbitting of thrust pads of unit-2

Repair and Re-metalling of Driving End (DE) Thrust Bearing of unit-2. repair and re-metalling of the Driving End (DE) thrust bearing to restore its operational condition and reliability. Dismantle the bearing assembly, clean all components, and inspect for wear, cracks, scoring, and other defects. Remove the damaged white metal (Babbitt), prepare the bearing surface, and perform re-metalling using approved procedures. Machine the bearing to OEM-specified dimensions and verify clearances, alignment, and surface finish. Reassemble the bearing, apply the required lubricant, conduct functional testing, and confirm acceptable temperature, vibration, and performance before returning the equipment to normal service.

Rebabbitting/repair of 25 nos. thrust pads for Unit-2. The scope includes cleaning and preparation of pad surfaces, removal of old Babbitt metal, and rebabbitting using Grade-1 white metal (90–92% tin, ISI marked). Machine and hand-scrape the pads to achieve the required profile, thickness, and surface finish. The finished pad thickness shall be 16.50 mm or as instructed by the Site In-charge.
