Throttle Cable

[Peter Collin]

I'm looking for a new throttle cable for my 46 BC12d. I like the door knob style.
The cable is good but the throttle lock doesn't hold so the RPM's keep on creeping up. Any suggestions?

Thanks
Peter

Re: Throttle Cable

Peter, most push-pull throttles have a packing behind the lock. Unscrew the lock, remove the old packing(I use a dental pic) and replace with two 1/8 in. leather strips cut slightly longer than the circumference of the shaft. I oil the strips with light oil. When you screw the lock back on it will allow for better throttle friction and lock. This fix works very well if the shaft is not pitted too badly, if so use crocus cloth to smooth the edges of the pits.

Thanks Larry.
I will try that. If that doesn't I'll get a new cable assembly.

Re: Throttle Cable

I like the vermeer type I have on mine. I have to push the knob in the center, to move it in or out, which I do with the palm of my hand. I can then turn the entire knob either direction for precise RPM adjustments.

Sorry to rant...

What's really annoying about throttle cables on the T-craft, is that the cable is strong enough to lift the entire airplane off the ground, and is sized about right to retract the landing gear on a DC-7.

An undamaged, properly functioning Stromberg carburetor has almost no friction, and could be easily operated by the smallest size model airplane "Gold'N'Rod" Bowden type pushrod.

The entire throttle cable system on the T-craft is a pain in the butt, wedged between the engine and the engine mount , attaching it to the bloody exhaust shroud, sneaking it between the engine mount lug and the oil tank, that AWFUL Adel clamp under the mount lug that you can't get to, etc. etc. It's heavy and difficult and about ten times more than needed.

The carburetor butterfly actually requires less actuating force than the carb heat box!

The Vernier adjustment is kinda cool to have, I must admit. OK, sorry for the hijack, rant off

I'm still laughing Bill
It seems to me that for all the brilliant engineering in the Tcraft, the throttle was sort of an aw s__t moment when Mr T discovered how badly everything lined up.

Re: Throttle Cable

mine works fine since 1969 C.G. did not do throttle on the crossover exhaust, check out the carb heat on the Model A, pull out the Bowden cable to put on...... the cable you refer too was a "Shakespere" modified at the factory with the 90 degree end,,,,

Re: Throttle Cable

I"m getting around to the "engine" stuff. REplacing the control cables and can't find from McFarlane or Spruce what I have. It's about 4' in length, has a solid 3/16" shaft with a 90 degree bend extending 1/2". End is drilled for a cotter key. Anyone know if these are still atainable or do you have to have it custom built? Thanks, Jack.
