How to remove choke and throttle knob from cable, help!

[OldDad67]

How do you remove the choke and throttle cable knobs on a P-15? It doesn't look like they unscrew from the shaft. I don't want to break them so my better sense says contact the experts before I ruin them. Thanks in advance.

Why do you need to remove them???

Good think you asked because they aren't meant to come off. The wire is cast into the knob.

behind the dash there is a nut that hold the entire assembly inthe dash undo the nut and the end of the cable on the carb and then you can take the entire unit out.  The knob does not come off.

Like Mark said the knobs are molded to the cable. If you want to replace the knobs you will either have to replace the whole cable or brake the knob off the cable end. I did this on my car and replaced them with custom made wood knobs.

Actually this something that I have been thinking about. 

 

My cables are sticky and hard to make small adjustments.  When I install my engine this winter (which in Minnesota can still be May) I plan to use new choke and throttle cables.

 

My question is whether anyone has thought of cleaning and sanding the inner wire and replacing the sheath from a new cable.

There was a fellow who, for a fee, (as I recall) would cast you a new knob on your cable.  

 

Some of you longtime members may recall him.  Can't think of his name right now.  Last old

car I knew him to have was a '47 Pontiac convertible.  I believe he liked airplanes, too.  

 

The idea of cleaning up the wire, and perhaps lubing that wire with graphite or lightweight oil

like 3 in 1 sounds reasonable.    

 

If the knob is in good condition but kinda grungy looking - I've had fairly good luck cleaning

them up with a couple things -- liquid chrome cleaner followed by some Maguires liquid cleaner/wax.

You can replace the sheath. On the end of the unit the sheath is crimped into the housing that the wire run throught.  It can be done just take you time.

 

Clean the old wire, steel wool to get rid of any burrs and built up gunk on the wire.  Then relube with a light coating of oil or lubraplate.

Thread the cable into the housing and then make sure it is smooth when pulling on the knob.

That would be this guy. I believe he lived near Dayton, Ohio but I do not have a clue on how to contact him.

Thank you it looked to me like they were molded but I wasn't sure. I purchased some screw on knobs off evilbay that look real close to stock but have threads. My thought is to may'be remove the stock knobs which have a lot of wear and thread the old cable shafts so I can put on the replacement knobs. Thanks to all who replied.

If your going to use new knobs, use new replacement cables where the knobs will screw-off.

Hang them someplace high and oil the heck out of the. I use marvel mystery oil. Put a catch pan under them because it drips all over but when you're done you should have a nice functional cable. Can also be done in conjunction with your removal of the inner piece and some sanding. Also pay attention to the routing. Even a new cable wont work well if its binding.

If you need a throttle knob for a Dodge, I have one I mistakenly bought for a Plymouth.  Very nice condition.  It is just the knob and its connected wire, you would have to use your current sheathing.  PM if interested.

There is supposed to be some resistance for these cables to work.  Too much cleaning and lubing will make them too slippery and they won't hold their position.  I cleaned all the cables on our D24 many years ago, and only applied a very light coat of oil on the wire, mostly to prevent corrosion, no problems since.  But I "overdid" the choke cable on our Terraplane and it won't hold where ever I set it.  I have freed frozen ones up by soaking in oil (MMO), then just pulled the wire out, cleaned it off, and reused it with no problems.
