WW II Radial engine mounts

Hey, mandrake! what exactly are you looking for, pictures of the engine cowling removed as if it was being serviced or pictures of the plane without the engine, like it was being replaced. I don't know if i have any of the latter, but who knows what I'll turn up.

I have a few good details of the B-17 eng mount that shows how it was constructed.Also shows good detail of exhaust around the mount.I'll try to scan them off for you.I also have good drawings of all the various ribs,spars and other internal structures if your interested.I don't have anything on the A-26 yet but I'm looking.

Here is a website about a group in Cincinnati restoring a B-17E. There are many wonderful detail photos on that site.

hey shrikes!, i am looking for pics of engines without cowling and also the way the engine was mounted on the plane, i have modeled the R-2800 engine for an A-26 but i dont know how the mount was on this one neither on the 1820´b-17 engine, so if you or someone else out here can help me with any reference regarding the engine mounts will be appreciated.

Hey mkee! yes i am interested in any reference you can provide, drawings pics, anything, i really appreciate it, and dont worry about the A-26, if you can help me with the B-17 thats more than enough.

Thanks a lot
i really appreciate it
Regards to you all!

Hector,

Seems that we're working on similar projects, so perhaps we can directly share research. I've got a few pics of the A-26 engine mounting and exhaust. They're 'service stand' photos from either USAF training or from the field in Pusan Korea. I won't have a chance until tomorrow night, at the earliest, to get them posted up, but I'll get them to you as soon as I can.


Best of Luck,

Jamie

Dont worry Jamie, i am not in a hurry so take your time, i also have some pics of the A-26 that may be useful for you, thanks in advance!

BTW my e-mail is hreymundo@yahoo.com
(i will be out of town for a cupple of days and i may not be able to answer til monday)

my best regards
Hector.

Mandrake,

I've been lucky enough to work for an outfit that operated both the A-26 and the B-17 as air tankers. Every time you look at the A-26 engines, you're looking at the engine mounts. The area between the cowl flaps and the leading edge of the wing is the engine mount. If you have it off the aircraft, without engine installed, it looks like a large inverted punch bowl. The engine is secured to the mount with 1/2 in bolts torqued to 1300 in lbs. The quick change unit (engine and mount) is secured to the wing with 3/8" bolts torqued to 150 in lbs. Before installation all the accessories and wiring are installed in the mount. Once installed, you spend a couple of hours hooking up hoses and wiring. 2 guys (who are familiar with the installation), can start draining the oil and five hours later have a new engine installed and be hitting the starter. (Been there, done that, got the T-shirt). Its really a nice installation for a radial.
The B-17 had a typical 30's engine mount - before removing the engine from the wing, you had to remove all the cowling and panels, remove all the accessories and disconnect all the wiring and hoses. You could then either remove the engine from the mount or remove both engine and mount from the wing (the latter is a heck of lot easier). You turn the engine and mount horizontal and set on the floor. Pull the engine from the mount and then reverse the process. The whole thing would usually take a couple of days to accomplish (less if you worked straight thru). I read somewhere the the record for changing an engine with this type of mount system (which is what all other radial systems in the US inventory used) was 8 hrs by a specially picked team of B-25 mechanics of the 22nd BG in the SWPA.
The mount its self is a circle made of 1 1/2" tubing about 2 1/2 ft in diameter (measure the tube the engine cylinders are on in your model. the circular tubing should just slide on over it at the back). It was attached to the fire wall with four legs, not sure how long they were, but when the mount was setting on the floor it stood about 3 ft tall. The legs angled out from the circular mount to 4 points just inside the skin of the nacelle at the fire wall.

Hope this helps a little.

Sorry this is late, but life can be interesting at times.

I've posted some of the pics I have in electronic format to the following location:

http://www.frontiernet.net/~biod/Images/a26/

I've pulled these pics from sites all over the web, and I hope you find them useful.

I do have some additional photos that my dad took while in Pusan, Korea in 1952-1953,but I haven't had a chance to scan them, yet. I'll try to get to that this weekend, so that I can post those pictures as well.


Best of Luck,

Jamie

If you need R-1820 detail photos, let me know...I have one. This is a distant shot of the motor, but I'm not back in the office until Monday.

Yes please Jeff, i will really appreciate any help you can provide, all the detail i can get from your engine will be very very helpful for mine, thanks a lot and i hope you can get the shots for me.

Was out of the office today, will photograph it on Tuesday and post the pictures here:

In the meantime, you can look at my models!! :-)

Jeff

Wow!, great models Jeff, congrats! and dont worry take your time, i will be waiting around your site

regards
Hector.

Day two of freezing rain, even the dog doesn't want to go outside...looks like with the 6-12 inches of snow coming later today, that it'll probably be Thursday at this point before I can get the 1820 pics posted.

Jeff

What? how come?? where do you live?? freezing rain??? here in Mexico City the weather is warm and sunny, i have never been in a situation such as that, i wouldnt be able to survive!! oh my God! freezing rain!!! :-(

My best regards
Hector.

Sorry about the delay.I had to get a new scanner and seem to be having trouble getting it to work.I have a friend that's going to try to beat this box of silicon in to submission for me.Hope to have the scans for you soon.
Mkee

Hi Hector,

I'll trade you an R-1820, 12 inches of snow over a 1" layer of ice, and -5 degree for a week in sunny Mexico...

I'm in NJ, about 45 minutes from NYC. Yup, it's still snowing outside...has been for the last 6 hours.

Jeff

mmmmmmmmm........ let me think....... mmmmmmmmmm....... sorry to disappoint you Jeff but i am pretty sure i wouldnt be able to make it, i have never been in a situation like that... you see, i am a pilot, and the owner of the plane sells boats and yachtes, actually the company´s name is PERFORMANCE BOATS so i fly him only to beautiful beaches, not only in Mexico but also in the US so with such a background now you can be sure that if i go to NJ i will defenetly freeze myself off, but in the mean time if you want you are invited to the sunny Mexico City, or Acapulco, or even Cancun, just let me know and you can have a great time in a warmer situation!

My best regards Jeff
and thanks
Hector.

Hi Mandrake, some pics of R-2800

Agradece muito, mim não falam o português mas eu tenho quis sempre aprender, isso pic na ligação sou awesome onde você o começou? se você tiver algum mais pics que você quer compartilhar me deixa saber, aquele o pics está indo ser muito útil. obrigado.
minha mais melhor consideração
Hector.
PD. haber si le entiendes :-)

Hector,

I've been down sick for the week. (darn flu bug!) So, I've not had a chance to get the scans done for you.

Here is a partial list of my sites for A-26 and R2800 pictures. (IMHO these are some of the best I've been able to find)

Engines at the A.A.M. -- Pratt & Whitney R-2800 <http://www.arkairmuseum.org/doublewasp2.html>
Corsair Pratt & Whitney R-2800-8 18-cylinder radial engine by Fine Art Models <http://www.fine-art-models.com/e/model/aircraft/corsair/thumbsPW.htm>

Some great up close shots of the R2800, but none of them are specific to the A-26:

http://www.aircraftresourcecenter.com/AWA1/201-300/walk258_Radial_Engines/walk258.htm


These are just good A-26 photo sites with lots of good detail information:

Bueno Suerte,

Jamie

Thanks Jamie, very helpful sites, i have e-mailed you, hope you are doing better!

saludos y gracias por la ayuda!
Hector.

Hi Hector, I undrstand you...try to use the Google, is the best...after you find the subject go to "images" and you´ll be able to see some pics of the subject that you choosed...
I started in ´69 with the aid of my father (I was only 8 years old)...I started mounting cars, planes and armoured cars, today I mount almost everything (except cars and sci-fi).
I´m sorry but my English isn´t very well...
Regards.

thanks a lot man! really appreciate it!

Haven't forgotten ya, but I haven't been back in the office in almost a week.

Jeff

not a problem man! i will keep waiting thanks for the advise!

regards
