Throttle Cable Question

[Achto 27,918]

What was the first year that Wheel Horse used the push pull throttle cables with the newer knobs like the one below? Did they start with the square nose tractors in '65 or were they used before then?

My 854 has that style, my 702 and 502 have the earlier rounded knobs. That leaves the 1963 models - not sure on those...

Looks like 63 had the round depressed knobs. Or they were replaced.  64 had them for sure

 

 

Course they look right at home on a 551 Suburban!

Yup. I had just got it running and driving and he had to come take one last look at his engine.

Yes, they were used on the 61 suburban 551

'61 and '62 should have this style knobs on the cables.

 

Still wondering if they switch to the newer concaved knobs in '63 or '64

BTW Dan found these 

Not painted but not a deal breaker. 

When they say locking they lock very well. 

Perfect replacement for tractors that use them or any model that has push pull cables. 

These are sometimes hard to find especially the locking ones.

Thanks,  i didn't catch that there were 2 different styles (rounded and concave) for the locking knobs.

So many little details over the years!

Wish someone made the concaved handle style with that serrated locking shaft.

Biggest thing I noticed about the the concave locking throttles is the ferrule inside the housing opens up and doesn't lock well. If you leave enough bare wire on the throttle end you can unhook the cable at the throttle. and turn the knob counter clockwise until the ferrule comes out of the housing and you can "crimp it tighter again so it grips the shaft better.

Not quite sure i understand?

In the housing where the cable attaches to the dash there is a brass ferrule that has threads on the outside. The bottom of the ferrule is beveled like a compression fitting ferrule but the top is flat. Imagine this piece with only one beveled end and threads on the outside.

 

 

The threads match threads on the inside of the cable housing and the bevel matches a bevel in the bottom of the housing. When you turn the knob to lock the throttle you are spinning the ferrule in the housing forcing the ferrule bevel against the bevel in the housing. Just like a compression fitting works on a copper line. The bevel is "crushed " on to the post of the throttle cable end. After many times locking the brass ferrule gets deformed and doesn't grip as tight 

[Mark siebenaler 107]

I get it.

Or at least have a better understanding 

So you're basically crimping the ferrule 

Slightly tighter with what ever maybe 

A electrical crimping tool?
