If you're going through Sheppard than you will not even touch a TF-34. They might still have one there to look at but thats about it. They are technically "modular" engines, but we all know that in the traditional "modular" concept this engine is NOT. They are relatively easy to drop and reinstall. With the right workers and nothing unforseen happens you could have one dropped and reninstalled in a day. Well built engines are relatively easy maintenance, but you get some that are crapped together, and you'll have fun with them. The quality of a TF-34 is usually based on the hot section temp it runs at. The limit for being on a wing is 860 degrees F. Engines come off test cell at 830 max. A barn burner will run between 795 and 810. Anything else, let us know, there are alot of people on this board that know theri stuff.

And 30MM Jr can hardly wait for his KC-135E to morph into an R model...or better yet, a 767!<img src=icon_smile_big.gif border=0 align=middle>

Hey, just wanted to say that four hours should be all its going to take to remove and install a motor. Thats if you get a really good crew. Vib runs are a bastard with the PBS 4100, water washes are fun to soak others behind the jet, APU changes are 2 hour jobs, and to correct a false statement, its 865 max. The normal operation is usually around 830-850. TEMS is a work of art, really bad art, but somewhat easy to get used to. Doors are easy openers, inner shrouds cut your fingers off, and the turkey feathers will slice and dice. Most LRU's are easy replacements...cept the fuel control and that dang pin that goes in the VG's cable. You will find out what I am talking about sooner or later. PLA's and VG's are easy to reset with the laptop, and throttle cables you dont have to work with, thats AR shop. If you really want to know anything, just ask. I was in OSAN for a year on that piece.

Yup, my mistake, 865 is max. Guess I've been out of the shop for a little too long. We have some good mechanics though, so our engines average between 810-830. We have a few 855 and 860's out there but not many, and most of those should be coming in shortly. raa4 was right about those turkey feathers....we had a broke jet in Cincy that needed an engine and while working with an unexperienced crew mostly made up of non-engine people, I sliced my hand and had 6 stitches at the local hospital. I tried to look on the bright side, at least I didn't have to hook up the pylon!! The 34 is a b*$ch sometimes but she can take a good licking and keep ticking. Ask all those geese..<img src=icon_smile_blackeye.gif border=0 align=middle><img src=icon_smile_wink.gif border=0 align=middle><img src=icon_smile_tongue.gif border=0 align=middle>

THE TF-34 WAS PRETTY EASY ENGINE TO LEARN AND WITH ALOT OF THE GUYS IN THE UNITS WHO HAVE WORKED THEM CAN TEACH YOU THE ROPES.
YES THOSE PYLON BOLTS WERE A REAL"B----!!!!!" OH AND YOU HAVE TO LOVE CHASING DOWN "GHOST VIB HITS" ON THAT "THE ERRORS MACHINE" TEMS. I HATED THAT THING!!!!!!!!!
OH YEAH WHEN CHANGING THE IDG OUT MAKE SURE NO ONE CRUSHS THE SEAL ON THE SHAFT,AINT NOTHING LIKE TAKING IT ALL APART AGAIN WHILE TRYING TO GREEN IT UP ON A FRIDAY NIGHT.

Now I remember that 20 degree night, with the light cart, with one light that worked, the oil cart that needed oil and the b1 stand that the rails did not come out of, and the QA inspector who just happened to be on the line that night! WHO'S GOT THE T.O.!!?? Thanks Goose<font size=4></font id=size4>

Also, watch the ladder...hitting the plug on the generator is also a bad omen...watch your eyes...always make sure to put up the lower door on left before someone starts the APU. The starter control valve cannon plug on left likes to eat your shirts, and the T5 amp is hard to get to when the oil tank is still hot. Well, its hard to get to no matter what actually. Along with the exciter box and cables for the plugs. Carry extra ceramic tips for leads to the ignitor plugs, thus they break all the time. There are two of them, leads and plugs...but only one box. Good luck and let us know how you are doing

ONE POINT OF SAFETY<img src=icon_smile_wink.gif border=0 align=middle>WHEN EVER YOU ARE WORKING ON THE ENGINE,ON WING,AND YOU ARE OPENING OR CLOSING THE OUTER NACELLE DOORS,MAKE SURE THAT BOTH DOORS ARE ALWAYS OPENED AND THAT YOU HAVE YOUR BODY POSITIONED SO THAT YOU ARE PUSHING OUTBOARD,ON THE OUTER NACELLE DOOR.REASON BEING IF THE LOWER DOOR IS CLOSED BY THE APU AND YOU SLIP ON THE LADDER OR STAND YOU COULD GET SERIOUSLY HURT.

I THINK WHAT HES TALKING ABOUT SGTGOOSE IS TECHNICAL ORDERS OR T.O.'S THEY NOW HVAE THEM ON DISC'S.

"GLAD TO HAVE BEEN THERE AND HAVE BEEN PROUD TO HAVE SERVERED"

Goose: I've heard of some engine shops having tech data available on laptop. Of course you'll never see them doing anything like that for Crew Chiefs, because they know we'd be destroying something...look at how abused our printed TOs are!

I've been TDY to tuscon a few times and I'd have to agree on the food and the town. I'm a big mountain biker and Tuscon was the greatest, loved the terrain. Good lUck in your career and you'll be seeing BC jets there for Snowbird every other year or so.

Tucson's where I discovered there's mexican food and Mexico City Style. Is Pinnacle Peak still there?

sounds good im so stocked about moving there. i was refering to the new to's theyre small laptops with the entire to on them and theyre on a wireless network that communicates with a main server and theyre updated automatically with changes and tcto's etc.....

wow.....that sounds cool.....and convenient

You burn 'em, we'll turn 'em

On C-17s we call it DTOS. Digital TO System...The are on CDs but you have to have a special program and a DVD drive to use them...mostly on govt computers. I dont have a hard time with them...They are quite easy if you know where you are supposed to be looking. The only bad part is that the battery dies quickly on the laptops...and I still prefer the paperback...DM is great, I was there for two weeks before Osan...Email a guy...his name is Dave Saunders...email is david.saunders@dm.af.mil. I dont know if he is actually on the A-10, but he can help you with some DM questions...Good luck
