Rember how I said when I tried to set timeing the mark was about 35 dgrees past TDC when it should have been 10 degrees retarded? Well the pully did slip! Checked piston 1 and TDC and it was way off. I made a new mark and did the timeing, so its at the right timeing now.

question is, do I need a new pully now? Nothing looks wrong about it, but could this cause damage?

yeah, it just slipping wont cause any issues with it running, it slipped where the a/c and p/s belt are driven.

i haven't looked at the miata pulley in while, but it's a harmonic balancer which means the outer pulley section should be cusioned with rubber in bewtween the portion that's on the crank, if it's loose enough to spin maybe it can walk it's way off the front

K, thanks. It seems that it slipped about 3 months ago, and hasent changed since. Odd huh.

PullEy. I'm not usually a spelling **** but **** if that isn't annoying. It's like BREAK PADS.

A pully is what I'm probably gonna do when I come home alone from the bar tonight. :(

Mine came apart at 6krpm once. If its slipping, get it replaced.

How is the pulley able to slip? Also, when I've removed the crank pulley on my '97 to replace the timing belt, I've never seen any rubber. Are you guys talking about the gear the timing belt goes on?

Luckily, no. It threw both belts and I think the sway bar stopped it before it went flying around, but it could have been real ugly. I just heard a loud grinding/knocking noise and the alternator light came on, so I shut it down and pulled over right away. Had to get a tow home.

I got one used from partsgroup... $60 I think.

trust me, the rubber is there. The piece that the belt rides on is separated from the middle section buy a thin pice of rubber, and I assume its glued together.

you know its starting to fail when your timing marks start moving around relative to the crank, the outer section of the pulley starts wobbling or the rubber starts sticking out...
