Throttle cable with friction lock control

[Rex Havis]

Does any one know what the packing material is that is used in the throttle cable friction lock.
Also if possible the name of company that sales the material or part.

I recall putting an o-ring in mine.

Mine had a split brass sleeve that was worn out. I made a new one and it works great. Tried an "O" ring but it didn't work for me. Always either too tight or slipped.

I fixed mine by calling McFarlane and ordering a Cessna 180 cable and that fixed my problem for good.....Tim

Rex,
I believe the original on mine was a leather washer and I have an extra. If you want to give me your mailing address I can mail it to you.

I'll put it in an envelope and mail it this afternoon. It's really not enough to cost anything and your very welcome.

Re: Throttle cable with friction lock control

Here is a picture of a Shakespeare and a Cessna throttle.

The Shakespeare has a rubber ferrule, you can see it and it has ribs on it and is brown in color.

The Cessna one has a nylon ferrule and it has one split in it.

Not sure why there are two threads on this but I will also put this in the other thread.

Rex,
The Shakespeare as in David's photo is the same as the original cable in my 41. My original does have a rubber ferrule but also a leather washer between the ferrule and nut. Hopefully yours is the same and the ferrule isn't completely worn out and the washer will make it tighten back up and lock again. If not I'm not sure what you can use to replace the ferrule.

I suspect that a short piece of rubber hose with 1/4" i.d. and 7/16" to 1/2" o.d. will work fine.

Hi guys,
I'm bringing a 46 BC12D back to life and I'm going with the McFarlane throttle assembly my a&p said you folks might be able to help with some 337 examples from the field approvals. If anybody has anything like that they wouldn't mind passing along, I'd appreciate it! Thanks!

Re: Throttle cable with friction lock control

I would give a good look at the definition of a major alteration.

I suspect that the throttle cable change is not a major alteration but merely an alteration.

Dave

here are the definitions from FAR part 1;

Major alteration means an alteration not listed in the aircraft, aircraft engine, or propeller specifications—

(1) That might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting airworthiness; or

(2) That is not done according to accepted practices or cannot be done by elementary operations.

Major repair means a repair:

(1) That, if improperly done, might appreciably affect weight, balance, structural strength, performance, powerplant operation, flight characteristics, or other qualities affecting airworthiness; or

(2) That is not done according to accepted practices or cannot be done by elementary operations.

If your mechanic absolutely has to do a 337 for replacing the throttle cable, get a new mechanic, it a minor and not a Cessna with factory support...Tim

Re: Throttle cable with friction lock control

Thanks guys, I may not have used the right terms, I'm new to the world of airplane restoration! I saw on some of the other threads that people have used the McFarlane c180 assembly and had gotten it field approved... Has any one here done that? Would I be better off trying to find a used throttle assembly?

Re: Throttle cable with friction lock control

It was just installed. I am the one who did it, log book entry only. You are money way ahead using the McFarlane. Nice smooth and good for another 50 years. Its a PMA'd part so I would just stick it in using the part number and faa pma as the approved data...but that is me. Tim
