How do I get this off of my Turbo

[overboosted1g]

So I'm in the process of rebuilding my pte 5031e and I cannot get the turbine shaft off the bolt is stripped. And is the nut reversed threads?

The turbine is usually part of the shaft, the compressor wheel comes off and the shaft is pulled out of the housing. The nut holding the compressor wheel on is indeed reverse threaded.

Are the turbine and shaft not one piece?

The nut that is on the compressor wheel is what comes off. You know it's reverse threaded so to take it off would be like installing a regular threaded nut.

Use channel locks, a socket, vice grips, or a vice to lock onto the turbine side.

Make sure you scribe the compressor to the lock nut and then to the shaft so you keep it in balance when put back together.

My problem is that I can only put a wrench on the cold side. The hot side is stripped.

There is a flat spot on the hot side. Using a vice or vice grips you should be able to hold it sufficiently to take the nut off of the compressor wheel.

I got it off I just had to find the right deep well socket that would bite the nut on the hot side.

Hold the end of the turbine with vicegrips, and spin the compressor nut off with an impact. It's very easy to bend the turbine shaft, so be very careful. Also, the turbine isn't stripped, it has been ground to balance it.

Probably ended up being a 12 point socket rather than a 6 point? Good to hear you got it off.

All shafts have that flat spot on the end of the shaft. It is not specifically for balancing, it is there to facilitate removal of the nut that holds the assembly together.

I used a 6 point impact socket on a hand ratchet.

Yea first turbo i pulled apart, i quickly realized it was reversed. (well i was also reading a tutorial as i went )

If you are doing it by a tutorial... make sure its full and detailed. And follow it to a T

I've rebuilt 4 turbos so far but I'm doing this one off the top of my head. The Turbo is now fully apart and awaiting a rebuild kit.

Nope- the grinding is done for balancing purposes.
