How to get turbo exhaust plate unstuck
Posted by: troy.w ()

Hi fellas,

Trying to rebuild this 64 turbo hot side.

I cannot get this plate unstuck for the life of me. I have tried heating up the housing, tapping on the shaft of the turbine (from the other side), gear puller (which doesn't grip the housing well enough).

What is the trick? Also, is there anyone in the group that rebuilds turbos?

Thanks!

Steve is closer to you but I also do that work. No matter who does the work you still run the risk of braking something. There are trick to be done but probably not with tools you have.

I had someone from here send me one like that and I did get it apart. I also said that there was no guarantee of what could be salvaged.

Steve sez: Agreed Ken and I had one a while back that defied me. Instead of breaking the wheel I just returned it to customer. I hate to say "If I break it it isn't my fault".

Heck it might be the one you were successful with. In fact I hope it was.

Heat. Penetrating oil. Heat. Penetrating oil. Don’t be in a rush. Alternate for a few days. It will come apart. Be gentle.

Stig I heated after soaking for days. Then soaked more and placed in my press and heated with oxy acetylene torch. Kept putting pressure on center of wheel. I finally couldn't stand pushing harder. Choices were quit or if I broke the wheel then email the customer with pic of damaged blades and say "tough luck I did my best". I chose to quit.

Steve not to ever question your work. If you give up I would have far sooner. Just trying to encourage Troy.

Fellas,

Thanks for the experience and encouragement. I don't think I have the right tools to give this a proper go. Maybe I would be better off finding one already disassembled.

You are welcome to bring that one by and I can give it a go, no guarantees though! Since I’m local. I can’t hold a candle to Steve or Ken but I have built a number for myself and club members here in town.

If it is any consolation must 'stuck' heat shields come loose from exh housing with gentle coaxing. Good luck with it Geoff.

I ended up using my press and heat after cleaning the joint with my bead blaster. It sill took a LOT of pressure to get the plate to come loose.

A couple things to try: Aero Kroil - give it several sprays and soak.

Also have heard that soaking in diesel fuel loosens up the carbon.

Oven cleaner also loosens up carbon.

I had one stuck pretty bad, lots of solvent got it, BUT. If there is a lot of rust where it seats and you clean the shield may no longer seat properly. Clarks has a shim to correct that problem.

Kroil, it seems to eat both carbon and rust.

I had a '39 Packard flathead 6 cyl with a few stuck valves in the block. After trying a myriad of methods, I ran into an old timer and He mentioned to try a mix of Marvel Mystery oil and acetone.
I sealed the intake and exhaust holes and filled them up with the mixture. Came back next day and was almost empty as the acetone had evaporated. Just went back every night for 4 days and they all came lose after tapping them back and forth like I had previously done!
