Key broke, how do you remove pulley? 94 1.8
Key broken and I'm guessing part of it is wedged in there to the point the coged pulley will not come off. Already chipped it in one spot trying to pry it off. There is no way to fit a puller behind it and no holes taped in it to get a balancer puller to screw in to......ideas?

 

PS is the crank fucked and this is futile?

 

Looking at it, seems like the crank is fubared.

 

You don't. The crank is fucked. Sorry :(

 

Ok well you do with a LOT of MAPP GAS. lol

Serious question I understand the crank is fucked but on a 200K motor anyone had any luck with welding the pulley back on? Its going in a Lemons car and the belt will definitely outlive the motor.

Thoughts, I cant be the first one to think/try this.

Like?

 

 

So in testing it looks like it can be welded.

 

Dude, i say you can sure as **** weld that thing back on for a ghetto *** fix, should only need a little tack weld too. Go for it and report back.

 

I've seen 1.6 cranks that were JB welded and held up until the timing belt snapped.

I'd say the traditional 1.6SNC fix (Loktite 660 IIRC) would work well here.

Use proper torque and red on the crank bolt. Remember, the Woodruff key is there to position the parts. It's bolt torque that should hold everything together.

In for ghetto pix!

 

I love it. I fixed my short noser in the above mentioned method and cracked piston rings with 25k miles on bandaids long before that thing was on it's way out. Weld away. Agreed it will only take a tiny weld.

 

I think you'll have serious issues with welding that on straight. The process of heating it up on one side without it being secured by the crank bolt will almost certainly cause it to sit unevenly.

That being said - I've repaired a number of cranks with damaged keyways. Some steady work with a tig welder and then have it looked over by a machine shop... But it sounds like you are looking for a quick fix..

 

That looks amazing.

 

Loctite fix that bitch.


A serious lemons build would probably replace that crank.

 

go to pick and pull and get a block with a good crank and a bunch of spear parts you can use or resale

and how do you mess up a crank like this wow never seen that ever

 

you must be new to miatatatas

 

To be fair, I've never seen anything this bad unless there was a supercharger involved.

Seriously, how?

 

LeMons is not serious.

As I got the car with out the AFM or crossover intake pipe and crank looks like this I bet your right. Header was heat wrapped. All pointing to hotside SC in its past.

 

yes I'm new to the Miata and that why I ask how this can happen ? I like to not have it happen to my Miata but I'm thinking of picking up a few back up engines out of the wrecking yard when I have some time to go pull them .
The ( you pull it ) here gets a Miata about every month or so.
