ii) The 5 number crankpin were inspected and following are the main observations:

        a) Minimum diameter observed :    169.75 mm

        b) Maximum diameter observed:    169.89 mm

Thus the total wear of the crankpin after damage was 0.25 mm which is considered to be very much on the higher side as the standard diameter specified by the Daihatsu engine manufacturer in their maintenance manual is 169.97 mm. 

iii) The deep bearing line marks were also observed on crankpin no. 1 due to seizure of crankpin bearing.

iii) Since the deep bearings line marks were still present. It was decided to undertake the grinding to the next undersize of 1.0 mm.

iv) The crankpin was polished and after grinding & polishing the final size of 168.97 mm to 168.99 mm was maintained. The crankpin no. 2 and 5 were also polished.RA POWER can maintan the surface finish of less then 20 Ra value.
