Building A Nissan KA24DE Motor - Tech Knowledge

We ran into a slight problem with the new crank. Since the factory crank is only half counterweighted, the factory block is cast with this in mind. Unfortunately for us, our new, fully-countered crank hit against small sections of the block and girdle. The block had to be modified, and we also deburred any casting flash to promote oil flow, while ensuring no debris would enter the lubrication system. The girdle was also clearanced for the now fully-countered crankshaft. The bright side to modifying the block is that the area interfering with the crank has no real critical usage and can easily be grinded. Since we were already grinding away at the bottom, we decided to clean up any left-over casting imperfections. View Related Article
