Tri-gear + Turbo = :(

[jjbardell]

Anyone out there struggle with the turbo and tri-gear combination?

I completed my engine build and mounted it on the airframe. Then all the problems started.

1) The turbo rubs the starter
2) The turbo rubs the steer tube bracket / steer tube bolt
3) The exhaust rubs the motor mount
4) The turbo bracket is about 1/5" too low, pulling the turbo down into the steer tube further when bolting down

It appears the exhaust manifold is about 1/4-1/2" to far to the right (pilot side when facing the aircraft).

Has anyone else struggled with this? Any solutions. I am on day three and just cannot get everything to fit.

Thanks. J

Reclocking the turbo compressor and turbine housings a few degrees should cure all your issues…. except the bracket and that can be bent slightly or spaced.

I think Geary is right. The compressor side looks like it is turned down too far. the manual has the instructions for re-clocking the turbo.

Thanks guys. I'll try a few more degrees on the compressor and see what happens. Although I don't think that will solve my exhaust pipe problem. I'd like to find a way to move the turbo manifold pipe over a bit. But I don't think that can be bent at all without breaking a weld or making the turbo sit at an angle.

I had ALL of the problems you are talking about.....too close, too far, bend here, bend there. I feel your pain.

Clocking the turbo helped get "better" clearance from the starter. I had to bend the nose gear stops way down and I'm not sure it's going to clear when the spring is compressed. My turbo was against the firewall, bowing it in a little. I ended up putting washers behind the motor mounts to move the engine forward a little. I was able to get it out just enough to get the turbo blanket wedged around the turbo against the firewall. Moving the engine forward created another problem for me. The oil cooler now touches the cowling. My exhaust hit the motor mount too. I took the exhaust to a muffler shop and they were able to make a dent into the lower pipe and expand it at the same time side ways so I have a flat spot but the pipe size is as original. I also had them weld the two pipes together as the springs didn't fit at the engine mount too. Feel free to contact me directly as I have pictures of all this. I talked to Kerry quite a bit about all these problems but he said I was the only one to encounter this stuff. As far as my progress, I have first engine start scheduled for tomorrow.
