Removing a harmonic balancer on a Nissan 300 zx 1989 Without shop air. How to lock the crankshaft from spinning while loosening the harmonic balancer center nut. Thanks guys?

Answer 1

Answer:

Unlike the Honda/Acura vehicles for which they make a specific crank pulley holding tool, on the Nissan VG30 engines pretty much the only (and best) way to remove the harmonic balancer is by wedging a pry bar between the flywheel/driveplate teeth to prevent the crankshaft from turning while you loosen the crankshaft bolt. In order to get that pry bar wedged in, you'll have to remove the two starter mounting bolts, and just push the starter out of the way. To loosen the crank bolt, it helps if you have a nice long 24" flex handle (breaker bar). It also helps if you have an assistant to hold the pry bar and keep it wedged in between the flywheel teeth at the right angle so you should then be able to give that breaker bar a good impact. Good luck! A easy way to remove a Harmonic Balancer nut even on a light truck is to use the starter motor! Put the socket and bar on the nut and check the direction of rotation of the engine, make sure you have it the right way around or it could swing right around and do damage, you want the end of the bar to be resting on the garage floor, keep your hands out of the way and touch the starter motor, Bingo! it`s undone!!!!
