I picked up a turbonetics evolution wastegate the other day and tried opening it up today to see which spring it had. I took all the allen bolts out and the top was still stuck. There is definitely a spring inside.

Any ideas to get this thing apart?

 

did you try pulling on it or tapping on it with something.. his has to come off.

 

I pulled and tapped it with hammer , guess I'll try a bigger hammer.

 

Hmm. There are only 6 bolts holding it together. Bigger hammer then like you said.

 

Big hammer took care of it.

 

it must be 200yrs old if its stuck on there lol.

 

post pics you might have missed a bolt or its rusted together. On my old wasted i got all the bolts out and it still didnt pop up. I throw it on the ground (yea i know) but it open then
