Crank pulley wobble

my crank pulley wobbles

What causes this problem and how cam I fix it? Will replacing the pulley fix the problem or is this more sinister?

Thanks for all you help

You need to either take to a mechanic for further investigation or have a look yourself depending how good you are mechanically.

It is typically caused by the crank pully bolt working loose..

The infamous short nose crank problem where the keyway is worn?
Take to your local MX5 specialist (update your location and we can suggest the nearest one).
Good luck.

Updated location. the crank pully is tight. What is the short nose crank problem?
Thanks for all your help.

Also is the Crank Pulley in my 1.6L the same as the 1.8L BP Engines?

Me neither...

To the OP:
1) Update your location in your user control panel -> profile -> location: __________
2) Do a search for short nose crank using the search function. There have been many threads on the issue.
3) The B6 crank pulley is different from the BP crank pulley from memory (happy to be corrected on this if someone can confirm otherwise). :mrgreen:
