My real 737 Throttle Conversion Pictures and Videos

[XOrionFE]

Hello all,

Finally getting started converting my real TQ.    I have posted a ton of pictures in the Media area on this site so just look in my album.    I believe my TQ is from a Lufthansa 737-500.     I know it if from Lufthansa because the 3 bay pedestal also has a little floppy disk box in it and when I opened it I found all the FMC program floppys from Lufthansa.   They say the data is for the 737-300 and 737-500.   My TQ was built in 1991 according to the markings stamped on it.   Anyway, I had journeyed out to Rob's (727737Nut)s house a few months back to see what he was doing with the conversion we all saw him post here.   He was very helpful in allowing me to take pictures, answer my questions and help me with a shopping list for parts.   He also had some spare odds and ends I bought directly from him.     Anyway, I am finally getting down to business.    My TQ was already pretty clean compared to others I have seen.   You can see in the gallery how it progressed as I dismantled the top covers and blew everything out with a compressor and then with a little extra work with a spare toothbrush I was really able to clean it up nicely without dismantling the whole thing.   Anyway, I also made a short video to show off the inner workings.  I have always been fascinated by how things are engineered and this TQ is quite marvelous to look at inside.  For those who have never seen the guts of one up close and personal I hope you will like the video.   Again, look in the gallery here on CB for my progress pictures.

Best regards,
Scott

Absolutely. 

Now that said Jack...it would be really cool if you could bring your homemade TQ for show and tell at the get together.   I would love to see it first hand!

Very nice work, actually it looks like alot of work converting a real TQ to operate to the same simulated TQ with every function.

True but in the end you have a component that will last forever versus a 'toy' that will wear out and or break eventually.  Trust me, there is nothing comparble to the real deal in feel and durability.  Plus the aftermarket toy repro's are 2 to as much as 5 times the cost of a real TQ plus conversion parts. 
Just my .02  

Call me anytime you need help or have questions Scott

Thanks for taking the time to do the video Scott.
Very informative and for the likes of people like me that will probably never get to own one, a good insight into how the real one operates.

Good luck with your conversion and please keep us updated as to the progress.

Hey Scott,
Waiting on the next TQ conversion update. I am amazed how clean was your throttle.
Keep up the good work

Hey Scott - your TQ looks really great too. I still don't have mine yet - it's being interfaced and there are some delays with that as I understand. Hope it is resolved soon(er).

That is the tough part I think. I have Phidgets cards I am planning to use on mine but may need to get another motor controller card yet.   Rob told me about a new board Tyler is producing that I think he was planning to use on yours so I may look into that as well as another option.   I think hooking up everything to the motors and such is the easier part but interfacing and getting it all working with the software is probably the more challenging part.  When I saw yours at robs it looked pretty much done except for the interface card.   I have to reach out to Tyler to find out more about this wonder board.

Yes, Tyler is planning to come down to Rob's (soon?  with that new board/software to test on my TQ. Then keep it as a  configured test sample and order the actual board for mine.

Well, making progress on motorizing my TQ.   Here is a new video link with an update:

Hi Scott

thank you

Polyclutch, used to be A&A Manufacturing, but I think they got bought up.

[mickc]

These clutches are normally over $200 a piece, but there is an Ebay seller who has them at $25 each at the moment.   I got 4 of them from him earlier this year and can recommend the seller.  they are listed here:

Mickc thank you for the link
which hub sprockets (roue dentée) do you recommend?
reference appreciate...

regards
rakouth

[mickc]

I got mine locally, they are called plate sprockets, and the size is 06A19 which you should be able to get anywhere.   I use the same chain for that throttles as is used on the trim drive sprocket, so I only have one type of chain.  This is number 35 roller chain, I used Tsubaki part number RS35-1-RP.

I had the sprocket bores machined out to be a press fit onto the clutch hub, and also use a bearing & shaft opposite the sprocket as once the chains /cables are tight there is quite a lot of side loading on the clutch that will quickly reduce its working life.

Hi Mickc
for gear motor power supply which the good choice 12v or 24v?
is one source power enough for both 2 motors
or one source for each over...
