i) Due to the repeated failure of bearings, it was decided by the client to get an audit of the crankshaft for all the major parameters. RA Power Solutions deputed two (2) technicians along with the onsite crankshaft grinding machine from New Delhi to Burkina Faso. During the initial inspection, the following was checked and observed.

a) The dimensional inspection of the crankpins was conducted, and excessive ovality was observed in all the crankpins. The readings for all the crankpins are pasted below:

SIZE OF CR PINS BEFORE REPAIR
	A	Aa	C	Cc	B	Bb	Min	Max	Ovality
CR-1	279.89	279.95	279.90	279.90	279.89	279.93	279.89	280.00	0.11 MM
CR-2	279.88	279.94	279.89	279.89	279.91	279.89	279.88	280.00	0.12 MM
CR-3	279.88	279.95	279.90	279.92	279.90	279.93	279.88	280.00	0.12 MM
CR-4	279.88	279.95	279.89	279.92	279.90	279.91	279.88	280.00	0.12 MM
CR-5	279.88	279.92	279.89	279.91	279.89	279.91	279.88	280.00	0.12 MM
CR-6	279.87	279.91	279.89	279.88	279.90	279.89	279.87	280.00	0.13 MM
CR-7	279.88	279.95	279.89	279.94	279.90	279.96	279.88	280.00	0.12 MM
CR-8	279.88	279.95	279.89	279.94	279.90	279.93	279.88	280.00	0.12 MM

b) As protocol, all the crankpins were checked for hardness by a portable hardness tester and were found within limits.

c) MPI was also undertaken to check the cracks, and no abnormality was observed.

ii) The grinding of all the eight (8) crankpins was executed onsite by our technicians. The first step size and tolerance of 0.02/0.03 MM were maintained.
