Throttle Linkage Simplification - “Morse” Cable Scheme

Because I'm a genius, unlike those Porsche engineers, I've decided I can do better than them in a couple of areas.

Hence the non-standard cables highlighted below:

The lower one in the pic is for the throttle.

I'm not a massive fan of the standard throttle linkage on a '70 car. It's an awful lot of parts to do a simple job:

Plenty to go wrong, in an area where going wrong can have unhappy consequences.

This thread on Pelican suggested an alternative scheme: http://forums.pelicanparts.com/porsche-911-technical-forum/309504-early-911-replacing-throttle-linkage-morse-cable.html

All the missing bits in this version of the diagram are replaced by a "Morse" cable:

In my case the specific type of cable I have used is called a Teleflex TFXTreme. Most commonly used on powerboats, I believe, and available from your friendly local yacht chandlery. Incidentally in buying these it turns out that, although Yacht Tax seems to exist, it's nowhere near as ridiculous as Porsche Tax.

Anyway.... this sort of thing:

The advantages of this type are high quality materials (corrosion resistant) and, importantly, small bend radius - nominal spec is 100mm minimum, but (in new-out-of-the-box state anyway) they remain smooth well beyond that spec. Point is they are flexible enough to easily make the control run for the throttle.

Final note - obvs my genius statement is slightly tongue in cheek. In fact Porsche changed the design later on, to get rid of all that bell-crank on the side of the gearbox nonsense. So a 964 has a cable run fairly similar to mine (but less flashy cable).

Pedal Cluster

Here's the rufurbished pedal cluster. Being RHD it has some slightly weird and wonderful extension rods, to bridge the gap from the accelerator and clutch pedals to the centre tunnel (much simpler in the LHD version).

As well as the plating and paint, it has new bushes and springs. Chris at Fenn Lane Motorsport makes them (including the NLA RHD clutch helper spring). So this is the first of probably many opportunities for me to say "thanks" to Chris.

Just for fun I'll bung in a link... http://www.fennlane.co.uk
... but it's possible that the website will still be under construction.
You may be thinking "I didn't know Chris was making those". It's additionally possible that I will mention a few more things you didn't know he makes. Lots of engineering at Fenn Lane, not so much marketing.

Anyway, let's have some pedal photos:

Parts

Here's what arrived with the car. Lots of parts. It's a full size build-your-own-early-911 jigsaw puzzle! With some missing pieces and some extraneous bits from another puzzle.

Collecting from Southampton

This part of the import process was also very easy. Turn up at warehouse, bit of paperwork and id checking, winch car onto trailer, off we go. A van was also involved, for the many boxes of spares.

Thanks to Mel of flyingbluedog transport. Mel did the trailer bit while I was being Man with Van.

On a Boat

vesselfinder.com is very cool. The car reached Southampton on 28 September 2014.

 

Leaving Queensland

Here's my car at the docks in Brisbane.

Some spares were stashed inside, some can be seen on the pallet. Engine, gearbox, suspension and steering were all temporarily back on the car, so it was a rolling chassis to make it easier to handle.

I'd never imported a car before. The process of booking space in a container, and sorting out the various paperwork, was made very simple by my shipping agents. Many thanks to Kingstown Shipping (in Hull) for that.

Import Duty and VAT on modern cars are a significant cost, but there is an exemption for historics. Using the Certificate of Authenticity from Porsche and a few other documents, Kingstown helped me to get the required exemption from the UK tax authorities. Total import duty and VAT were about 5% of purchase price.
