cab 1 a) Raising of pantograph. b) Working of auxiliary compressor motor (MCPA) and Arno (EG), particularly observing behavior during starting and for abnormal noise. c) Working of main compressor. d) Working of both exhausters for various positions of exhausters isolating switch. e) Cutting IN and cutting OUT of compressor governor (RGCP). f) Blowing of safety valves. g) Working of blowers particularly watching for abnormal noise. h) Observation of contractors for abnormal sound and sparking. i) Observe deviation of main ammeters taking two traction notches in forward and reverse directions. j) Test wheel slip relay (QD), progression and regression relays (Q51 and Q 52). k) Test electro-valve VEF. 8.6.1.4 Low tension tests before and after inspection a) Testing of master controller for notch-by-notch progression and regression and total time for regression. b) Test working of sanders c) Test working of exhauster isolating switch (ZPV). 8.6.2 Details of inspections to be carried out by various sections. Section M1 a) Inspect the various components of transmission, for breakage deformation or cracks, check silent block for slackness and the general condition of various washers. b) Check the general condition of body and bogie frame, links, pins, springs for cracks possibly by dye penetrant or magnetic particle method. c) Check centre pivot side housing for cracks and side bearer cover for proper seating. Check the oil level and replenish. d) Check the snubber assembly for broken springs and replace any broken spring. e) Check sanders for satisfactory operation and correct height and ensure that they are filled.
f) Inspect and if required refill the fire extinguishers. g) Lubricate gear cases, buffing and draw gear & screw couplings. h) Check general condition of brake rigging, renew worn-out brake blocks and adjust brake rigging as required. Clean and check hand brake for proper operation. Clean and lubricate slack adjuster. i) Check traction motor axle suspension bearing, remove complete wick assembly, clean the wicks by soaking them in lubricant, remove foreign material from lubricating surface. j) Axle boxes, examine and top up oil if required. Section M3 a) Visually inspect and clean all roof insulators. b) Check condition of contact surface of the pantographs, remove sharp edges of current collecting strips, check strips for thickness, lubricate pans with graphite grease, check shunts and spring for damage or wear, examine the steps, check raising and lowering operations, adjust throttle valve if necessary. Section M5 a) Check foundation bolts, fan and its blade clean exhauster, compressor tray, check oil level and oil leakage in compressors and exhausters and clean the oil trays under the exhausters and compressors. b) Check couplings and lubricate compressor and exhauster. c) Check drain pipes of trays and suction pipe. d) Check HS4, HB5, F1, VA-1B, MU-2B, C3W distributor valves for correct functioning. Overhaul the valves. Section El a) Blow out the loco before inspection. b) Clean loco roof and body. c) Troubleshooting defects. Section E2 a) Check electrolyte level and top up battery cells, if necessary. b) Clean all insulators. c) Check specific gravity and voltage of pilot cells & record.
