Wastegate Bowden cable attachment

by Jacques De Jonghe in 912 / 914 Technical Questions 5 years ago

Hello all, yesterday during a climb at around 5000ft, I lost turbo power on my 914. Was like coming back to a 912 80HP! Map dropped from 35 to less than 25. After a power cycling of the TCU without effect I did a precautionary landing on the nearest airport (well, very very far from where I live!).

Checking on the ground, I saw that the return spring of the wastegate was loose and the wastegate bowden cable was disconnected. See pictures.

Now, what is not clear for me is how to order a new bowden cable and the broken item? See below item 14 (spring) of IPC fig. 78-10-00-2.

Is that all included in the item 11 of the IPC fig. 76-10-00-1?

Thanks, Jacques.

I would expect that the #11 "Cable, Bowden Assembly" on the TCU End in Fig.76-10-00-1 would also include items #8, 9, and 10, but nothing more.

Any parts needed on the Turbo/Spring End would need to be ordered as individual items.
