Sprint rotating shifter

PostPost by: archigator » Sun Jun 19, 2005 1:23 am

Recently my shifter on my Sprint has started rotating about its
fastening bolt... not the shift knob, but the shifter itself. It is
held fast by a washer/nut that torques down on the integral bushing,
and appears to be designed as a metal-on-metal friction connection
dependant upon the tighness of the washer/nut. The rubber bushing
appears to be okay, but even when I crank down on the washer/nut to get
it as tight as possible, the shifter still rotates under the pressure
of shifting. Anyvbody else have this happen? Would some friction
material such as a rubber washer between the shifter and the plate it
attaches to be a potential solution?

As you observe the inner sleeve of the shift lever bushing is held in
place by the clamping force of the nut / washer. The nut / washer is
actually ( or should be) a machined nut and sleeve that fits inside the
inner sleeve of the bushing and prevents any freeplay sideways as well
as clamping from the top.

If you have the proper machined nut and sleeve and cannot get it to
clamp the bushing in place tightly dismantle it and check that it is
not bottoming out on the base of the threaded section of change lever
that comes out of the gearbox.

Inspect the rubber bushing closely also when you dismantle it as
sometimes it is hard to detemine when the rubber parts company from the
steel innner or outer sleeve of the bushing.

Gary, I had the same problem when I fitted my gearstick.

I simply put a small washer under the clamping nut.

Seems to work OK

Needs a new rubber bushing .... the rubber has debonded from the inner metal
sleeve.
You can do a temperary fix with a washer, but that takes the rubber out of
the system. Worked for the early Elans since they did not have the bushing
... just don't put you tongue between your teeth when you shift.

I replaced the bushing and the washers with Dave bean parts and
haven't had the problem since.
