Ah looks like (oops posted Hastelloy earlier) Inconel- pccenergygroup.com/assets/smw_docs/fmhx.pdf (no stress relief required- key attribute.. I'm familiar with INCO 82)
Can you weld or do you have someone to help you? I would be concerned about losing a stationary vane as well as rubbing the wheel...do the vanes have a tenon that extends into the ring & is peened or are they welded in? Looks like a Z evident in the photo..if so the crack may have initiated in the tenon hole and become challenging to chase...seems like an odd place to crack with little temperature- ( I'm involved with large frame machines) but remember everyone is an expert on the Internet .

What do you use the brake for? Just before engaging the crash box?

Anyway enjoying the thread...

Holy. Crap.
What a thread!
Is there really enough beer in RI to get you through this?
You should really find a way to work this into your Christmas Card this year. Just because.

I agree, although Gerry did state earlier in the thread that this is common and Jim is offering the correct rod... based on this I have to assume this is a routine fix.

Yes



Great stuff here Gerry, very educational!

Thank you for the flowers!
I would assume it would be pretty pricey it all depends on what is found.
Jim at PPS would really be the one to answer this.
Your right on flight status
I have to go back and reread my posts to make sure it makes sense.
The fact that people ask questions also helps.
There is alot of little consumables that add up when reassembling a complete engine.
Even the jet a consumption on the test cell can be close to 500$
although in comparison to say a mercury engine it may be less.

Excellent observation
I have a tig but i cant weld for Sh@t. I will go real easy on the petal.
im curios on the gas though straight AR or ar-he?
yes sir on the brake. The n2 system on the 53 is totally isolated from the N1 gas producer.
By design it works well it allows you to stop it at ground idle obviously only for seconds.
here they look welded.[IMG][/IMG]

LOL sometimes we wonder into ma.
A gift certificate to Boston logans fuel dock would make a hell of a stocking stuffer!!!

Yes it is Scot as a matter of fact its actually ok and permitted to have cracks through out various parts.
i will post a picture out of the 1140 page military technical manual showing this particular nozzle and the accepted cracks.

No way Jon you got me beat by far! :O

here some info.

what you see still together here is the basically the N1 gas producer. this is actually the engine
the parts that have been removed so far is the N2 "Turbine" which is what extracts the power from the gas producer.
Note... they spin at different rotations.

Great thread Jerry! Off topic a bit.....Block was fun this summer...what I remember of it. Looking forward to next yr. Personally, I think your nuts digging this deep into those engines, but that's me. I have trouble re-assembling a Lego toy after disassembly! Good luck and Im really enjoying your thread.... Oh, are the Arensons coming in the near future???
