83 Turbo Esprit Wastegate diaphragm


Recommended Posts

83 Turbo Esprit.  The waste-gate diaphragm split so, as expected, it wasn't regulating the turbo pressure.  I have a new diaphragm from JAE but can't figure out how to get the old out of the "cup",washer, diaphragm sandwich.  Do the two aluminum parts just separate or are they threaded together?

Thanks for your help!

Hey Rich,

 

 

The diaphragm just separates, can be replaced right in the car.

 

Back the bolts out until the are each held by a couple threads, then separate the top & bottom of the wastegate body (bolts shown on the images below, either side of the data plate) then the top & bottom can be released. Be cautious as there are springy bits inside...

Just gently pry the upper and lower halves apart, no threading.

 

For sure, it might require some prying.
