Throttle cable for '68 M20C

[zerobearing2]

Anyone have any tips on locating a new throttle cable for my '68 M20C? Its been progressively getting worse, and now its stiff as hell. Afraid I'm gunna break it off one of these days. Annual starts soon, so figured its good time to replace.

Try McFarlane.  http://www.mcfarlane-aviation.com/

 

If they don't have it on the shelf, you can send your old one and they'll make a duplicate.  Give your other cables a very close inspection as well... losing the mixture cable could lead to a very bad day as well.

Read somewhere on here recently about getting McFarlane to reproduce one under owner produced part  I couldn't find a new cable at all last year, (mine has the micro switch on the barrel behind the panel), and the field approval process is a task if not impossible in these parts. That's the route I'm going to go.

Macfarlene, makes a good product, but the replacement into the old sleeve is a pita, is not a two hour job, doable with lots of patience.

I was also going to suggest McFarlane, but make sure you have your A&P's concurrence first.  McFarlane doesn't make certified throttle cables for Mooneys, so you'd be doing this as an "owner-produced part"--you send them your cable and tell them "make one just like it."  Once it comes back, your A&P needs to agree that it conforms to the aircraft type design, and then he can put it in (and the log entry should state that it's an owner-produced part).  This is all perfectly legal, but a bit out of the ordinary.

One consideration is that you could pull the throttle cable out entirely then  soak it over night in solvent  then re-lube it.

That way you would have mess with machining hole to  mount the throttle position micro switches if you replace a it new cable unless direct replacement.

If you do choose to remove throttle cable,  make sure you replace cable clamp with a new one, DO NOT reuse it. I know a guy who reused the cable clamp and his throttle got stuck about 1400 RPM. This  makes it  challenging  on landing when your engine is still producing power on  approach to landing.

I  don't believe  that Mcfarlane has a PMA's throttle cable for a direct replacement.  I think if  you deviate Mooney's original throttle cable design  you are going have deal with cutting into the new cable housing/sheath for the micro switches mounting and then you would have to adjust throttle position switches for the gear warning. Which may not be that big of a deal but there is probably a lot of paper work.

Something to consider.
