The major crankshaft details of Daihatsu 8DK-28 are as follows

Inspection of the crankshaft of Daihatsu 8DK-28

• Two numbers of crankpin bearings were reported damaged.
• On inspection of the crank pins excessive ovality was observed and at the same time, it was jointly decided to check the remaining six crank pins.
• On inspection of all the crankpins eight numbers were observed to have excessive ovality against the standard diameter of 235 mm, we observed dimensions of 234.72 m to 234.86 mm hence it was decided to undertake the grinding of all eight crankpins.
• As a normal protocol, the crankpins were subject to inspection of hardness crack detection by MPI, inspection of deflection, etc.
• All other parameters have been found within limits.
• RA Power Solution team of technicians successfully executed the repair of eight crankpins in six days only.
• The undersize crank pin bearings of 0.5 mm have been also supplied by RA Power Solutions.
