Illustrated Parts Catalog

[Taylor Maid]

Does anyone know where I can view an illustrated parts catalog online, or where I can find one real fast?

I am also looking for other's experiences...I was flying yesturday and got a pretty good elevator vibration and concluded it was from a pretty floppy trim tab. THe right elevator had a little play in it too. Anyone have any experience with this type of thing? I am hoping it is just a few hardware parts and be on my way.

Thanks!!

I felt that vibration several months ago. It only occurred on a no-wind, full-stall landing. My assumption was the trim tab was the culprit. The loose play was there.
Complete rebuild of the trim system. Components in the elevator were rebushed, replaced as needed. Bellcrank, pushrods, jackscrew, etc. Cables, pulleys cleaned.
Works great now.
But still hear that buzz occasionally. Now I'm assuming it is turbulence from the wing over the tail brace wires. Warning of an approaching stall. I don't feel it in the yoke. More a sound from the rear.
Doesn't do it in a stall at altitude.

I get a "drumming" sound approaching the stall at all altitudes: I think it is the turbulence of the stall advancing up the upper wing surface from the trailing edge, although it does sound like it does come from the rear of the aircraft. It's quite loud, even overcomes the ANR headsets, so it makes a good stall warner. It stops when actually stalled. We have the old Stits HX-90 lightweight fabric, which I guess can drum easier than the medium-weight fabrics.

Also, check the tension of your tailbrace wires. Loose ones can also cause some vibration back there. And also check for differential elevator movement. Lift one up a little bit, the other should follow it immediately. If not, there is some play at the elevator horn attachment/or bolts, which might also cause a similar effect.

Let us know what you find.

Were you able to complete this through the access panels or did you have to cut into the fabric?

Thanks for all your input!

Thanks for the suggestions, Rob. I pulled both elevators off when I redid the trim tab. Had to tilt each to get the horn to exit the hole. Easier with two people and tilting at the same time. Same pain getting the horns back together.
I did notice it would be very easy to leave the control horn bolts slightly loose and cause the play you mentioned. I checked that again after reassembly. And again after the first flight.
I may tighten the upper brace wires about 1/4 turn on the nut just to see if it changes the sound. I do check the tension before every flight. Never know when a child might swing on them!

Actually, the best part of having an aircraft like this is enjoying the kids (big & little) discovering how it is made. Introducing them to basic aeronautics. Also, the wonder that something this old can fly. You can't experience that in a spam can. Welll, maybe some!

Taylor Maid, I removed enough cloth from the top and bottom of the elevator to gain easy access to all of the trim components. Disassembled everything. Replaced the jackscrew, rebushed all holes, replaced bolts, cleaned & greased everything.
Note: it is easy to over-tension the spring now. A bit of rosin on the cable around the pulleys, keep the spring loose and all works great.
Another Note: reassembly. Check the direction of the bolts in the bellcrank. They rub the underside of the cloth. Glue a thin square of aluminum on the fabric at the rubbing point.

Yes, Larry KT, you are right, when disassembling/reassembling the elevators to the horizontal stabilisers, you do need two people to get the elevator lower horns out of /back into the gap between the two upper fuselage longerons. This involves engaging the aft trim pulley stop nut from the left elevator through the aperture in the right elevator, and in my opinion cannot be achieved single-handed.
{ To others: I would welcome a method to do this single-handed! }

To your notes, Larry: before the application of Rosin, the cable and pulleys must be clean of all greases and oils before the application of the stuff. Else it won't grip. And you are right, don't over-tension the long trim spring that maintains tension of the trim cable circuit.

To Taylor Maid: I have some pics of the internals of the trim tab mechanism inside the elevator at http://www.taylorcraft.org.uk (just do a search for "trim"). Also there is a very important elevator lube hole (to lube the internal jackscrew), this lube hole should be accessible fron outside the fabric: pictures at http://www.Taylorcraft.org.uk/OtherR...tionPhotos.htm (about 2/3 the way down the page). Some of these photos show access after I had removed all the fabric, but a lot can be achieved throught the lower inspection panels, or as Larry suggests, some minor small holes through the top (which can be patched).

In response to Larry's (big & little) point: Every year we have a fly-out to our local gliding club: they welcome us in our powered aircraft to their field, and we then go for a trip in their gliders. We then take them for a ride in our planes, and all bills, dues and financial liabilities are considered mutually sorted. Ale and food then ensue, in sufficient quantities to maintain the friendly atmosphere, and the whole day is considered an excercise in mutual aviation appreciation.

Anyway, this year, I took up some university gliding cadets, and after they had flown me around the local area in my aeroplane, were amazed that it could be somewhere near 60 years old, and that they had actually flown an aeroplane (shock, horror!). Some of them were excellent pilots of these high-performance gliders, and I was glad they enjoyed the experience as much as I did being flown in their machines.

Will we see you again at Alliance in July, Larry?

Thanks for the replies, guys! It looks like I need a new jackscrew...I have been searching univair and other places online and can't seem to find a replacement jackscrew. ANyone know where I can get one for a 1946 BC-12D? I am planning on getting a hold of the factory after Easter, but I am way to antsy to get it up in the air!

Spark Plug torque

The Continental book says
300-360 in/lbs, or 25-30 ft/lbs.

[Taylor Maid]

Alrighty, my woes are answered. I called the Taylorcraft factory and they are manufactuing my jackscrew as we speak...not a bad price either. They also said that they are planning on putting an illustrated parts catalog on their website in pdf format. Perfect place to start a Christmas list!

Thanks for all your help guys!

Jack Screew

Taylor Maid,
I hate to be a lawn mower in your flower garder but if I were you I would make them send the part COD.If you send them money you will be lucky if you see any parts or your money for a looong time.I waited 3 months for a set of leading edges that they have been in the process of making everytime I call.One time I was even told they were finished and would be shipped on Monday.....that was over a month ago!!!!
They have also told a lot of other people that they had the parts made or they were currently making the parts,these people sent them money and have never seen a part!!!
I will look to see if I have an extra jack screew,if I do you can have it.

Taylor Maid,

Check your Private Messages, I've had also had problems with parts from the Factory. Hopefully your experiences with them will be better than mine, but I sure wouldn't hold my breath.

Just curious ; how much is the new jack screw "they " are making for you!! WE have them here, new pulleys too!!

illustrated parts catalogue

I've actually had good luck calling Jerry at the factory. They've been prompt and nice to work with. However, quality may be an issue sometimes. I sent back a pair of wooden aileron tip ribs that were very sloppily made they charged $16.50 each for--I made my own instead.

Suppose to be $30 I was giddy about that. Do you have them in stock Forrest?
