PART B:- Repairing of drive pinion & driven arm etc. of pinion size(160mm X 34mm)

Repairing of drive & driven pinion. (Drive=25 pinion + driven = 90 pinion = 115 pinion) Breakup 1.Metal filing by welding method at abnormal tear bear gear pinion by special welding electrodes at site.( 24” X 02 layer X 14.48=704.64) 2.After metal filling hard facing by hard facing electrodes /steel electrodes.(24”X 02 layer X 14.68=704.64). 3.Grinding work of each teeth for giving proper shape & size as per req. size. 4.(01 fitter X 1022.00)+ 01 helper X 985.00) dived by 06 nos.=335.50) So, rate of per teeth repairing = 704.64 +704.64+ 334.50=1743.78

For repairing of driven pinion arm ‘V’ cutting work & multi layer welding work by steel electrodes. Cutting work – 32” X 04 nos. X 12.00= 1536.00 Welding work- 32” X 04 nos. X 04 layer X 14.68= 7516.00

Repairing of drive & driven pinion bearing. A.)M.S plate cutting work for above job base plate(10”+20”) X 02 side X 02 nos. X 12.00=1440.00 R.B cutting – 32” X 12nos. X 12.00 = 4608.00 B.)welding for above work. Base welding- 20” X 04 nos. X 04 layer X 14.68= 4697.60 R.B welding- 20” X 12 nos. X 04 layer X 14.68= 14092.80
