<VV> Broken Clutch cable history

[Mark Durham]

guys, there is a good solution to this. Aircraft quality cable and
swedge ends will fix this problem. use your chart and Google aircraft
spruce and special co and order the proper cable and ends you need.
Just about any A & P aircraft mechanic can swedge the ends at your
local airport for you, too. Mark Durham

Maybe we can get a vendor to use finer strands in their next run of
cables???  How do the NOS cables fit into the chart you have?

  Hank- I've owned my current early turbo since 1998, and since 2001,
have put 6000 miles a year on it. I've broken 4 clutch cables since
I've owned it. I've broken three original N.O.S. cables, and 1 of the
newer style cables. As bestI'm able to determine, the N.O.S. cables
were lasting approximately 20000 miles, and the newer style cable only
lasted 6000 miles. When I broke the newer style cable after only one
year, I had to figure out why. The failure wasat the first pulley
leaving the clutch pedal, so that implies some sort of bending fatigue
problem, which should NOThappen if the cable design is correct for the
pulley radius. Anyways, I went ahead and counted up the number of
wires on the one that broke and found a chart that gave the minimum
recommended pulley radius versus the number of strands for a given
cable diameter, and found that the newer style cable wasn't even CLOSE
to havingenough strands for the pulley radius. After that, I started
using N.O.S. cables. Thre
 e years ago, when I replacedthe cable, I decided that I was going to
convert to hydraulic actuation, before it broke- and it didn't happen!
Nowit's not going to be driven until I do the conversion! My car has a
heavy duty pressure plate, early 1980's Camaro throw-out bearing and
99% of my driving is not on the highways, so I probably do more
shifting and clutching than normal, and the throw out bearing and
pressure  plate combination has to be some sort of contributing
factor. I never sidestep the clutch!Kevin Nash
