Research on the Repair Method and Application of a Diesel Engine Tappet Hole
It describes a repairing method of engine tappet holes,which belongs to a repairing technology for diesel crankcases with de-fective tappet holes due to machining accuracy problems.It's suitable for almost all kinds of crankcases with defective tappet holes and the same material.It's a highly practical and environmental solution with good economic value for saving the scrapped crankcases with defective tappet holes due to diameter,roundness,position tolerance issues,which helps reduce rejection rate,improve the produc-tion efficiency.It had been proved that it works without the risks such as bush deforming,loosening,or crankcase cracking,etc.This method filled the gaps in the technology of saving the scrapped diesel crankcases with defective tappet holes due to machining quality issues.
