Crank pulley bolt

[wheelz510]

Can anyone point me in the right direction to figure out what size tap i would need for the harmonic balancer bolt? I screwed up the first two threads of the crankshaft and i have no idea what size tap i need. This is on an l28 crank.

 

Sorry if this has been covered, but after an hour of searching i could not find anything.

Crank bolt is 16mm x 1.5 pitch

You may want to take a VERY close look at the first threads before sticking a tap to it. If you just tap it what if you are out of synch? A better approach may be to gently file the first threads back some. There is a good amount of threads on down in there. So two less at the front won't be a loss of strength. However if you ar not in synch when the tap gets down to the undamaged threads you will be doing more harm than good.

 

Use a magnify glass and goos light to get a proper idea of what and how far to take action.

 

Good luck & hope this helps,

Hey Phred,

 

What was the length of the harmonic balancer bolt? 16mm thread, 1.5 pitch, ??? length? If you know, it would be greatly appreciated!

I've seen two different crank pulley bolt lengths.

 

Just though I'd throw that in.
