Hello,

*I'm looking for a J.C. Higgins crank drive side, one with J.C.
Higgins "in the spider" of the chainring. The one I have has stripped
threads where it receives the pedal. The length of the arm is 165mm,
or 6.5 inches long.
Thanks for any and all advice,
Dave

Install a thread insert, such as Helicoil into the crank.

thanks thirty-six,
i wound up finding one. a mechanic friend of mine said "timeserts"
are better than helicoils, so i'll eventually fix the stripped one.

You want 9/16" x 20 tpi for bicycle pedals, not the typical 9/16" UNF
which is 18tpi .

Not sure, it might be ex-catalogue. These guys used to sell the taps
and repair coils (in fives) which I believed were Helicoil:
http://www.framebuilding.com/economy...mebuilding.htm
but it seems they've stopped and offer the traditional block insert
repair. With the helicoil style, reaming was not necessary, the
remaining old threads mostly removed with a normal drilling bit in a
drill press. The tap would align with the old thread and remain true
as long as you didn't freehand the drilling with a portable drilling
machine. It might be that the reaming operation is necessary with the
block insert but I'd say there's a fair chance you wouldn't get it
precisely aligned with a hand tool. I'm surprised in the withdrawal
of sale, I know there was a preference for the coil style by my local
professional frame builder and mechanic and he'd had plenty of
experience with the older block insert.

It might just be that the coil style requires a better cut of thread
and many dont want to have to learn the skill of hand cutting a good
thread.

Having watched the information on those, the presenter is achieving
the anatomically impossible - talking ********.

Give us an entertainment value. If it could be considered comical I
might watch.
