Orenda 14 2018 pt.5 Turbine attachment

The turbine was stuck to the main rotor shaft, so we had to design and build a special, brute force tool to get it off without any damage.

That puller is a work of art!

[@AgentJayZ]

I told our friendly neighborhood machinist what I needed, and allowed him some creative control, and he made something rock solid and functionally optimized.

[@SKYLANDBAK]

Sheila Walker - I should imagine it was split using a 1 - 2mm slitting saw on a milling machine..If you want a precision cut, I can't think of another option with conventional tooling....Just had another look to see if the machining marks would give an indication & it looks like it was simply cut using a power hacksaw or bandsaw..If this was the case I would have pushed for a partial refund on that $1000 outlay ;)

[@TheAlignmentGuy_TM]

Presses can be stimulating. Nothing like the Ker-POW of victory, assuming nothing important gets damaged including the operator. The holy quartet of stuck parts: Pressure, vibration, heat, and patience. JMF TAG

[@markpearce9619]

So… I take it that brown corduroy trousers will now be mandatory PPE clothing when removing stuck fast conical taper rings! 😜 Always wondered where the term "Holy crap" originated from. 😂😂 Glad that no injuries were sustained, Jay. As ever, many thanks and much appreciation for all that you post. 👍👍

[@guyh3403]

Wow. That tool is a pure thing of beauty on itself!

[@johnnyj540]

Jay you're gonna love this, I made almost the same tool...well similar for a similar situation only instead of hydraulic I had a screw in a screw. I assembled it in pieces like you did only when I had all the pressure I could get on the inner screw I whacked the center screw with a hard steel hammer and they would pop right off. Genius I thought, some years later I used to grind the tapers on the same type locking system, needless to say it makes you appreciate close tolerance tapers. Well I seized a part in the gauge and since the gauge was worth far more that the part was ....damn had to write another cause and corrective action report on a Friday as usual.

[@drubradley8821]

LOL... Stuck parts are no joke, and the higher the pressure goes up, the scarier and more violent things get when they finally do let go. I can remember trying to knock some bearing races out and the hydraulic press was shacking, and so were we, LOL... when it finally let go, the 90,000 sq. ft. industrial building with 20 inch thick concrete foundation shook, and businesses in a 3 to 4 block radius, felt it, many had damaged parts, that were being run on their CNC machines..... spooky stuff!!! and yes, violent and loud!!! The amount of HP that lets go in a nano second yikes...

[@ThePeachJames]

OK, try figuring this one- 600 PSI under a 8" disk...with a 1" gap above said disk. I just about let my undies out, and it still didn't move. The next step was the 55 ton hydraulic press, which did shift it (along with some hammer application...easy to do with the cage out of the valve...). Yes, because a stop check valve with 600 PSI of steam on one side, and 0 on the other side...and a gap, is great for understanding of what _can_ happen with wild amounts of pressure difference. (30 000 lb or so...) I'm glad it had stuck as solid as it did with the temperature difference & crud, because had it gone "bang" with the steam behind it, I'm not sure the top of the valve would have stood it...see USS Iwa Jima for example of what can happen when valve bonnets fail under steam... en.wikipedia.org/wiki/USS_Iwo_Jima_(LPH-2)#Catastrophic_boiler_accident

[@DScottDuncan]

Jay, nice craftsmanship on the tool! I'll have to show that to Mark at BoMar... he will appreciate it! He recently got my new & improved (double the capacity!) fuel cell done & painted, so as time permits, I can install it back on the stand. Once it is installed & the stand plumbed & wired, the J44 can finally get back to its resting place & I can continue its assembly. I read the comments regarding the T-53 & agree that it takes a while if you have nothing else to do & it takes much longer if it is only part time. My costs were kept lower by my good buddy Mark & his connections but I have to wait weeks or months sometimes because he owns a business & always has a full plate, not to mention that his wife is going through breast cancer treatments now, with the last one coming tomorrow (Friday, 08.03.2018). He is stretched pretty thin. Keep up the good work & take care for now... DD

Innovation to overcome a problem, brilliant ideas 👍🔩🔧

[@HoundDogMech]

I just made my 47th straight year to the Airventure EAA convention at Oshkosh Wisconsin and saw a lot of vintage jets ... Big Bucks even in Canadian money . Man just curious but what kind of Money are we talking to overhaul these old Jet engines & who is using them. Another great video really learn a lot watching you.

[@unclejoeoakland]

I love these... Please keep on with the good work!

[@ryanmoeller3308]

I love watching your video's my friend!! I start the power plant portion of Aviation Maintenance Technician School in a month. Keep up the great work. 👍👍

[@AgentJayZ]

Where you taking your training?

[@seannot-telling9806]

I knew that you were going to have the collar jump. I have been there with other things and even when you know it's going to happen you just don't know the when. That compressor core would make a different looking Christmas tree. You could color the blades red,green and blue. One thing about using it as a Christmas tree my cat would not knock that one over. In the past I have used everything from water bottles on the bast to cement blocks. The blocks did the trick. An 18Lb (8.1Kg) Savanah cat does wonders to the tree. One last thought. I hope you keep a change of closes at the shop for the Oh $#!* times. Stay safe and keep the videos coming. Thank You.

[@jw4620]

I really like the looks of that little red 'rocket' in the doorway.

[@AgentJayZ]

CTX1300... it's much sportier than most people think.

[@RolandElliottFirstG]

That is a huge amount of pressure to remove that collet, I would have been wearing body protection, oh and by the way what did those new casings cost ?

[@FabricatorFactory]

Cool. Cool tool. Nice machine work. Great Keep up the good work.

[@laertesl4324]

Now that you mention props for a science-fiction movie, yesterday I was watching episode 17th of season 3 of Star Trek Voyager and I am pretty sure that some objets that are seen when they land on a planet are some combustion liners and some casings from a jet engine.

[@halowraith1]

has anyone heard anything from the FHC with their Jumo 004 rebuild? they put up a short video on facebook about 3 years ago and nothing else has been revealed since.

[@VitorMoura]

Nice! Rust is strong there.

[@georgegonzalez2442]

Do you have an in-town source of really cold stuff, like liquid Nitrogen? They used that to insert the Merlin valve seats, it might shrink that collar just enough to break it free.

[@AgentJayZ]

We don't even have a local source of dry ice. Brute force is always preferred.

[@Revvavver]

I would wonder if you do short during video 2-3min with the best moment about test running turbojet engine. Thank you

[@Gkuljian]

Very cool. I ballparked a grand for that thing. Ouch.

[@JimHou-y8c]

Agent Jz, would you please explain how each stage of turbine disk or compressor disk connected with each other ? and the way they assembled ? Thanks

[@index7787]

Clever tool

[@AgentJayZ]

I've been called a striking tool before, but never a clever one. Thanks!

[@RahulKumar-nv9cf]

Sir, firstly thank you for these exciting videos, i had a question that in the turbine section of an engine whether the turbine stator will be in first position or turbine blade along the axis of engine?

[@grahamj9101]

Nozzle guide vanes (ie, stator vanes) are needed to turn the flow in a circumferential direction, before the gas enters the rotor blades.

[@RahulKumar-nv9cf]

Thank you, sir

[@grahamj9101]

Normally, there is a row of NGVs before a row of turbine rotor blades, which is described as a turbine stage. However, having told you this, there can be an exception. It is possible to design a contra-rotating turbine without a row of NGVs between the two rotors.

[@bend1483]

Oooh that tool gives me the warm fuzzies. So precise and perfect for the job. Did you only try giving it a tap with the drift and hammer once you had got to 9000psi and it didn't move or did you try earlier?

[@AgentJayZ]

Hit it at 8 thousand, which was supposed to be my limit. Pumped her to 9 thou, bashed on it, and it jumped up a fair ways... so I did too. Let go with a bang.

[@ChrisComley]

The puller is inspired, though half the fun is coming up with the idea and if it's based on a GE device not quite so "smart" to come up with the idea. :) It's always ironic that something you knock up for a one off (or "maybe use again one day") job is just a shiny and smooth as a ten thousand buck engine part. More so even!

[@AgentJayZ]

We've already used it again, and it was needed. Next video...

[@RallyRat]

Yet another reason why I think the Aheadset (bicycle head set) patent should not have been granted, due to prior art. Haha

[@jaarryifleshblood315]

Are jets the leanest burning engines?

[@AgentJayZ]

Interesting question. Long answer. Stay tuned...

[@shabaznihal8427]

Agent jz bro r u a fan of Honda bikes I see a lot of bike behind the jet engines

[@AgentJayZ]

Honda, Trek, Moose, Suzuki, Kawasaki, Rocky Mountain, Specialized... I'm a fan of bikes...

[@shabaznihal8427]

Great I'm a bike fan to my favourite yamaha

[@JlerchTampa]

7069 lbs of force applied (31,445 Newton), Yea I bet it did jump a little! :)

[@3rdGenGuy]

is that what it has to handle running , or how much pressure it has in a resting state?

[@bobxdark370]

It would be cool if, when you do your paint jobs to protect parts against corrosion, or making them look good, you would paint all cold areas black or silver, and all hot areas orange like that ladder you got there, just like an old V8 orange look. ....EDIT: or would it all just flake off and it's better to have no paint in hot sections....

[@AgentJayZ]

The turbine rear frame, jet pipe and the exhaust nozzle are unpainted because they can get over 800 degrees F. Otherwise I will paint the "cold section" any color the owner wants.
