Let me dig out my spare pulley tonite and see if i can measure the thread...

Cheers

Well Home Depot was a bust, but I confirmed that this bolt is a _14mm_ diameter, NOT 16mm. So the search goes on for 14mmx1.5mmx55mm...

Well, I can ship a 14 on tuesday if you need it!!! :)

Cheers

Anyone find a source for the bolt? Mcmaster doesnt have them. :(

Jeff Alton 03-05-2006 08:48 PM

I can get the 14X1.5 bolt for anyone who needs it. They are rather plentiful up here as is just about any metric fastner you want. I am at the wharehouse at least once a week!

Cheers

CBRacerX 03-06-2006 05:23 AM

OK Jeff, If you send me some bolts, I will send around to the US gang that needs them.

Thanks a bunch!

Chris

Jeff Alton 03-06-2006 06:25 AM

How many do you need. I will ship ground this time due to cost. Just confrim we want a 14X1.5 55mm long.

Cheers

CBRacerX 03-06-2006 07:00 AM

Sounds like Chris Martin and I both need one, plus a spare for the inevitable "oops" during the grinding. Sounds like 3, unless Chris Bennet also needs one?

We do need to be sure the bolt is threaded all the way from the head to the end.

Cheers,

Chris

I'm good. My buddy Eric already ordered me a new one.
Thanks for thinking of me though.

Okay, I will pick up some 14x1.5x55 fully threaded bolts tomorrrow. I can't find my spare pulley so I hope these are the right ones.

Cheers

I finally got the pulley off, thanks for the ideas guys. I made a 'tool' out of a piece of 1/8" steel with a nut welded to the center. Long bolt inserted in the center popped the pulley off.

Now I need to find TDC again...

CBRacerX 03-06-2006 07:27 PM

Interesting Chris, I thought about something like this using the factory attachment bolt. Like maybe cuttind down a worn large punch. Can you take a pic?

VincentVega 03-06-2006 07:51 PM

It's ugly, but it works.

That doesn't look anything like what I though would be used! How did you make that work?

Same concept of the Porsche tool, but it grabs the bolt welded to the plate, rather than the threads of the actual pulley.

I ground the threads off the last inch or so of the through bolt, similar to the Porsche tool so not to harm the crank threads, just a little insurance. Once the center bolt bottoms inside the crank it pops the pulley off.

The Porsche tool takes off the pulley and damper as one. Those parts are balanced together. If you do separate them using something like Chris' tool just be sure to mark them some way beforehand.

A good metric hardware source is http://www.metricmcc.com/

Updated specs that I am trying to find somewhere...

I'll measure the actual tool tonight, but I think you've got something wrong. The pulley bolt is an M14, but the tool threads into the pulley, and i'll double check, but I think it's 16mm..... you don't want to thread into the crank, you thread into the pulley, and push against the crank........

-Eric

ekessel 03-10-2006 06:30 PM

I can't find the broken puller, but measuring the pulley bolt, and the inside threaded part of the pulley it's obvious, you need an M16 bolt. If you want me to take any pictures of the pulley let me know.
