Jet Tools: Race Puller

A demonstration of how to remove a turbine shaft bearing without damaging it. We use a hydraulic actuator along with a specialized puller tool designed to grip the bearing race.
No tools or parts were harmed in the making of this video.

Hello AgentJayZ ocne again another great video.. AgentJayZ may i ask how long does it take to learn all of this in school ? I know school can only taught you a few things, but most of this will come from experience and time. Thanks have a good day.

[AgentJayZ]

@zero00tolerance There are many institutes that have courses to train engine techs, or A&P techs in the USA. My training course was a year long. But I've also been an aircraft, machine, and engine enthusiast since I was a kid.

I think if you are interested in engines and aircraft and how they work, are willing to learn new things, and try to have good workmanship, you have the right stuff to work on jets.

Got a question about noise reduction in jets: had an idea from somewhere that having unequal numbers of parts moving through air past each other reduces resonance and the levels of noise, specifically an odd number of moving parts going past an even number of parts in the other direction. I'm wondering if you should show noise reduction technologies you come across, and if that extends to different numbers of stator vanes than the corresponding stage fan blades (compressor or turbine)?

[AgentJayZ]

@deSloleye Absolutely. That is extremely important, and Sir Frank discovered that the hard way.

In one of his very first running prototypes, there were 30 turbine blades and 30 nozzle vanes guiding the gases into the turbine.

Basically he had created a several hundred horsepower siren, but didn't know that until it ran.

His next prototype had 31 vanes and 29 blades. Still loud, but much, much quieter.

[AgentJayZ]

@deSloleye Most of the noise reduction technologies are not really visible, and none of them make much of a subject for videos, but i should try to come up with something.

Awesome work sir!! Living in Australia I can't even imagine cold like that.... :-)

[AgentJayZ]

@fatboycrash A week before I shot this, we had about ten days of -30C. Below -20C, the cold stops being an inconvenience, and becomes a serious thing.

THE best Gas turbine engine vids onthe entire net, bar none. I have learnt so much from these videos, i used them to improve my knowlege before going for a job with GE aviation, im now 5 months into my training, cant wait to get hands on :0 thanks jay!

[AgentJayZ]

@thspamed Wow, that's great!

I feel like I've helped something good happen.

I wish you much success!

AJZ, do you think you could do a video on thrust reversing if you have any engines which can demonstrate that?

[belchnasty]

Cracking videos Jayz! keep them coming. I work in the marine industry & our gas turbine onbord my ship is very agricultural and not an aero derivative.

Amazing to see how the oher half live!

[fatboycrash]

Haha!! We have exactly the opposite problem... +30C is just bloody hot and makes it hard work, +40C is when it starts to get dangerous and you think about staying under shade... Great vids mate, I don't think I'll ever be a Jet Tech but they are fascinating and have really helped me understand the operation of 'jets'.
