I have a 356A coupe and getting it ready for driving this Spring. I have the brake and clutch pedals out of the car and thought to replace the clutch cable. But, I’m confused as to which cable to order – the online listings like the Porsche PET aren’t too clear. - A. Cunningham, Monroeville, PA.
Yes, there continues to be confusion about the cables due to misleading printed catalogs and present on-line entries. Many guys seem to go by the length of the cable when ordering. All old used cables in the car for 20-40 years have stretched, so length isn’t a good identifier but can be a rough guide. By the way, the difference in lengths of new cables is only about 3 inches. So, a better guide is the thread diameters on both ends of the cable. If you disregard the very early cable with the outer casing, you’ll see other three cables all have a different combination of end threads. So the thread diameter is the key to which cable you need.
Take a look at the chart below.
In the chart I added the part number of the German company, Gemo, that supplies these cables to the after-market. In the last several years, Gemo has identified their cables with a red sleeve marked with their part number – a convenient way to lessen the confusion with these cables.
See our website for details for cable end fittings for each model/transmission combination. Also, I recommend application of the Wurth product, HHS-K lubricant, on the moving parts at each cable end.
