1.0 PURPOSE:
To describe a standard operating procedure for replacement of coupling bolts of reactors.
2.0 SCOPE:
The standard operating procedure describes in detail the method of replacing coupling bolts of reactors.
3.0 RESPONSIBILITY:
The responsibility of replacing the coupling bolts of reactors lies with the staff of rank not lower than junior utility operator of maintenance department.
The responsibility of preparing, reviewing and approving the standard operating procedure lies with the Manager - Maintenance, Head of Production and Head of QAD respectively.
4.0 METHOD:
4.1 Isolate the equipment electrically.
4.2 Remove the belts/coupling guard.
4.3 Remove V-belts /coupling and then loosen the mounting bolts of gear box. Remove the gear box from the equipment.
4.4 Check the condition of gear box and reactor couplings. If they are found cracked / with holes enlarged / loose on the shaft replace them as per Interal SOP/SOP Format.
4.5 If the condition of couplings is satisfactory, replace the coupling bushes and bolts. Position the gear box in it's place.
4.6 Tighten the base plate bolts of the gear box.
