Miata Big Nose Crank Failure and repair
Posted: Thu Jul 05, 2007 12:28 pm
I happend to pop the hood on the miata with the engine running and noticed a good amount of wobble on the crank pulley. Tore it down and found the woodruff key on the crank was broken in two and wearing out the key way.
I salavaged a good timing cog and pulley boss from a parts motor and bought a new bolt, key and, loctite. I followed the directions for a Short nose failure and it seemed to work. Took the car out for a quick rip yesterday after letting the loctite sit for 2+days and checking the timing and, it feels stronger than ever before. Grand total spend on the fix ~$30
Better watch out at SPC.... 8)
