Margaret at Mo-Ma did mention that I needed to grind the end of the cable
off,
so it wasn't too long.B Didn't mention aboutB this, though.B B I can give it
a try.
Thanks, Rick.
There is apparentally only one mfgr of all the speedo cables we get here in
the US. Margaret has seen failures of her rebuilt speedos because the inner
portion was too long. The new cables were being made too long. They should be
3/8 (Check this-I think its 3/8 -but its in my shop manual).
She campaigned with all the suppliers to get the cables made correctly until
she finally cornered the manufacturer. She told him about all the speedos
and tachs which were getting broken because the inner portion was too long. He
laughed and told her she shouldn't complain, it was good for her business.
I used a grinding wheel to shorten mine, then a fine file to dress the edge.
