ECHP-I- Replacement of existing worn out gear box SCN 450 by reconditioned Gear box SCN-450 in Conveyor-45

Charges for lifting the Gearbox from ground floor to Conveyor 45 headend (40 meter height) and shifting the Gear box near to bed and lifting the Gear box by another chain block and placed at Gear box bed. Decoupling wornout gear box from head pulley slow speed coupling, removing RMT flexible element, and brake assembly from bed. Drain oil from wornout gear box, removing gear box bed bolt, removing the cooling fan cover from input shaft, leading and lifting the gear box from the bed. Arranging supporting plates of fixture to the required position providing hydraulic jack on the fixture and tighten its bolt and nuts, heating and removing the coupling from the wornout gear box output shaft by removing hydraulic jack. Measuring and preparing output shaft, transporting of waste oil about 1 barrel available at site heating the released slow speed coupling in oil bath by fire wood to the required temperature, lifting, positioning and shrink fitting the coupling with reconditioned gear box shaft. After cooling of waste oil stored in drums and kept inside the site. Arranging supporting plates of fixture to the required position providing hydraulic jack on the fixture and tighten its bolt and nuts heating and removing the brake drum from the wornout gear box input shaft by removing hydraulic jack. Measuring and preparing input shaft, transporting of waste oil about 1 barrel available at site heating the released brake drum/new brake drum in oil bath by fire wood to the required temperature lifting, positioning and shrink fit the brake drum with the reconditioned gear box input shaft. After cooling the waste oil store in drums and keep inside the site. Arranging the chain block, leading, lifting the reconditioned gear box after assembling the slow speed coupling on output shaft and brake drum on input shaft of the reconditioned gear box and positioning the reconditioned gearbox on the bed. Checking the alignment of fluid coupling with motor, checking the alignment of fluid coupling with gear box checking the alignment with respect to drive pulley, including all the tools, cost of consumables T & P's etc., complete.
