Title: Wastegate removal???
Post by: subsonic on October 23, 2007, 12:23:02 pm

How to I remove the actuator and the wastegate from a garrett T3 (internal wastegate)?  I am going to have the turbine bead blasted so I want to take it off.

Its not removeable so you could just tape up the vents and fittings to keep the beads out of it.

No ***?

None of that stuff comes off?  What if it does not hold vacume?  Is the whole turbine junk then?

Pictures worth a thousand words.

On the right of the turbine, sticking up in the air.  Thats what I am taliking about.  That piece has a diaphram in it right?  

Its all nasty lookin and rusty.  I want the wastegate to operate all nice and smooth.   The inside must be all gunked up as well.  I figured that if I am doing a complete turbo rebuild, then this should be cleaned out, inspected, tested etc...

I've gotten mine apart but I think the actual wastegate housing that holds the diaphragm is pressed into the turbine housing.  I've gotten it to move but not come out.  I've also not really tried to remove it, but I noticed it moved around on me once I got the wastegate valve out.  If you look on the top of the wastegate housing, around the inside of the "lip" there is a spring-like snapring.  You will see one end of it tapered toward the inside so you can get a small scribe or flat screwdriver in there and pry it out.  Once it is out, the top comes off of the wastegate.  The guts are easy enough to remove once that's done.  Sorry, I didn't take pictures while I was doing it.
