Healey 3000 - throttle linkage [cable]

[JonMiller]

Folks,

I wonder if you can help? I'm currently working on a 1960 3000 the car was Originally left hand drive but has been converted to RHD. When this was done she was fitted with a throttle cable instead of the linkage (she also has the later HS6 SUs)

This setup is very stiff (due to lack of leverage I suspect) the cable is fine and the linkage on the carbs seems OK.

My question is what are the options, is it a horrible job to fit the original type linkage and would it be any better, or is there a proper throttle cable kit that can be bought?

Many Thanks

Jon

DMD Australia have what is probably a great unit, as the rest of their stuff is top-flight.

While you're looking at the cable be sure to note their 295 hp 3.8 liter aluminum Healey engine.

Jon,
I used the manifold mounting bracket from Denis Welch for my cable conversion. I love it. They make it for LHD or RHD. I modified mine with a Lokar stainless cable and also lengthened the lever on the pedal shaft. I like Welch's kit over others because it is designed to pull the throttle shaft up from above rather than pulling it down.

Sounds interesting, do you have a link to his website (if he has one)?

Thanks

Ask for the set up for twin carbs rather than the Webbers.

If your throttle pedal movement is correct, it could be worth having a good look at the cable. There are some fantastic cables that are teflon lined and used on mountain bike brakes, they are virtually friction free.

This is the current setup, It works OK but due to the lack of leverage and the need for decent springs to ensure the throttle butterflys close completely it is quite a stiff action and tends to stick when initially pressing the pedal.

As you can see its a bit "Heath Robinson!" And also has done away with the original pedal assembly which both the linkage sets listed above would have needed retained.

Any idea where I would get one of the correct length?

Well now, to each his own, but that is a pretty primitive set-up. My pedal goes out the side of the pedal box as original. If you will send me an email directly to: linwoodrose@mac.com, I will send you some images this evening if you are interested.

Hi,

Could anyone with a <span style="text-decoration: underline"><span style="font-weight: bold">RHD</span></span> BT7 or BJ7 post up a picture of the throttle pedal and how it is fixed to the bulkhead under the dash?

Many Thanks
Jon
