Turbine Housings -0108
 

Just recently found out there are no new rear turbo housings -0108. Hartzell had a vendor I guess that went out of business, and they say they are not supporting it.

It is the only one that I know of that is approved for the rear on the P337’s.

Any body know of a replacement or STC for a different one?

Fortunately mine only has about 300 hrs on it and just needs a new bearing. The other parts are available, just the turbine housing is the problem. Overhaulers used to be able to have the housings welded, I guess that is not allowed now.

When I hit that wall
 

Faced with that issue a few years ago, with a scraping turbo, the only solution was a complete new turbo

Problem is new ones are not available either, Hartzell has no new turbine housings

Urgent need for Turbo Housing
 

This is a thread that goes back a few years, but for the me need is now. After a long slog sorting out a fuel controller issue, getting the bird back into annual and taking her aloft to 12.5K', the MP suddenly dropped out of the rear engine and we decided to come home. Inspection of the engine oil showed a glitter paint quality to it and a seized rear turbo shaft. Turbo was sent out to a turbo shop (ATC); they report the housing is cracked beyond repair.

So I'm looking high and low for a rear turbo housing for my P337G. Rear turbo part number is 406610-9022. Turbine housing itself is 407169-0007. Multiple websites claim availability, but when called there is nothing in stock. I've put in calls to Don in OK and Owen in TN; waiting to hear from each. Apparently the manufacturer isn't making them anymore.

Hope there are some good ideas here. Advice?

Might be time to look for a replacement that is similar and have a DER approve it

337 rear turbo
 

Yes, the DER approval for using the front one (identical turbo except for minor mounting issues) onto the rear engine is our Current plan. But who is the DER for sign-off? Which Powerplant DER is certified for the turbo AND is near to Maryland? We have the Directory but haven't a clue who to call.

Thanks so much,
