Re: Spam Can IA worries about BC12-D

The attached drawing is for an L-2M not a BC-12D however at the bottom of the drawing is part #DCO-A6063 which is the crankcase baffle for this application. I only assume it is similar on a BC-12D.

My L-2B does not have the required baffle installed.

Re: Spam Can IA worries about BC12-D

I'm baffled. Is Forrest saying there should or should not be a crankcase baffle? Does anyone have a photo or drawing showing proper baffling for the -65 installation?

Forrest,
Crispy also had the same baffle going back to the oil pan. My father always said the only thing he knew wrong with the t-craft was the poor baffling because even after they re-made all the baffles it still ran a little hot. Most of the t-crafts I've had never had this baffle and none of them ran hot. Someone told dad once that the oil pan baffle could cause problems.....do you think this would do it? We have been trying to decide weather or not to put it on the O200 with the short mount,I know the F-19's don't have it so we had planned not to make one for it......what do you think?

Forrest,

My '46 DID have that under crankcase baffle, however, my L-2 does not. The gentleman who restored it used a totally different way of 'pressurizing' the heat muff. Can those under the crankcase baffles still be obtained???

The bottom Bill, the bottom, it really did not have much of a lip and of course no louvers, Most were replaced quickly or a lip added. The larger hole in the nose cowl was supposed to make up the difference.
I do not agree since you must "draw" the air through the baffle system , not "push" it! sure they had baffles maybe not all of them!
Did all your Tcrafts have the under crankcase baffle that attached above the carb spider and went forward to the "mouth" under the prop hub... I bet not!! That baffle let the air flow go back to the oil tank. It is one of the biggest violations of the old "conforms to Type Certificate" issue that I have seen out in the field. Happy holidays, and yes there were 3 fits of boot cowl to nose cowl combinations at the factory remember that old ( +/- 1/8th in.) over all tolance , it had to be made up somewhere. :rolleyes2:

Bill,
I am sure what Forest was saying the short cowl and/or nose bowl that was used on the ace model failed inspection and was from the reject or reclaim stock.

Re: Spam Can IA worries about BC12-D

The "Ace" ( BC12D1) came with one control wheel, no universal installed, one door, one set of rudder pedals, a short cowling that was left over as rejects, a misshappen nose bowl large openings , no glove box holes in panel, and numerous other missing stuff. All other was added as an "option". Neat & light!

I can't believe it! You mean there was a cowl on a Taylorcraft SHORTER than the "short" cowl I have now??? The left front cyl. baffling barely fits in the one I have! Did they leave out the cooling baffles too?

Re: Spam Can IA worries about BC12-D

This IA would have a fit if a true Ace model came into his shop. 12 gal nose tank only, no door on the left side, no steps, left control wheel only,and no lift handles on the tail. I may even be missining some of the deleted items.
Now on the tail brace wires, I had 2 old time Tcraft IA's tell me to tighten them to a low base tone when strumed.

Carl I agree with everything except one control wheel. I owned one and i know of at least one more in my area. They both had 2 wheels. What about it Forrest? Marv

Re: Spam Can IA worries about BC12-D

Adding another wing tank should be just a log book entry, with a ref. to the TCDS. that its a factory change. A new wt and bal, with the weight of the tank at the station and an equipment list update, I've done this with a 7AC, that I added another wing tank.

Re: Spam Can IA worries about BC12-D

I was told that Crispy came from the factory with 2 wing tanks...one in each wing. They were both in it when my great granfather did the first recover in the early 1950's.

My 1940, BC-65, Ser.# 2466, NC29624, came from the factory with 12-gal. nose tank only. I'm putting in 6-gal. right side wing tank during the rebuild.

A brand new IA

I think I narrowed down your problem for you... this is a problem you can fix.

If he is gearing up to remove one wing tank, gear up to remove one IA.

Thank you--I looked and missed that.
