If you are there, replace the plastic ball joints for nice priced metal.
They tend to break.
They also fit the gearthingy's

Hello Herman.

What purpose do you have for the second link on the gear shifter arm? (the one on the middle of the arm)

Regards.
Jon

Jon: I think this is a shorted and modified gearshift.

It is another experiment to make shifting shorter.



Its mounted on the chassis here (experimental).


It needs a rubber for vibrations on chassis and I noticed that shifting to 2nd/4th the lever comes a bit near to the seat.
I can use that for thr 5th.
It's always a bit far away for me and if I make the chassis mount a bit more to the front it wil come closer in 1-3-5 gear.
Also shifting is shorter.
This is on my 1.6 because my 2.2 has the graham way, but maybe I chhange that to.
It's less stress on the material.
My 2.2its like this now.

I have a similar bracket around the shifter pipe. There was too much flex in the pipe for precise shifting.
I have a set of control cables for an outboard motor. They are stiff enough that I plan to use for a cable shifting system, like you find in Hondas. I have seen it in this forum, but I don't think it was on a stock Murena engine.
Anyway, that is a planned modification.  Grin

I wrote this some years ago, it is still correct Smiley

Hermans invention could be useful, since it will fix the rod in the pivot point transversally, but a good rule is always to check all other parts before you make improvements Smiley

It's not my invention.
It was on the Murena from Jean Piere Beltoise.

It is true that if all points are without play the shifting is not bad but still a bit to much.
Also if chassis make contact somewhere in the rod system you will here that.
Especial when the car stands still noises are heard and it is possible you hear a slight vibration on the stick.
Therefore I think somewhere some rubber has to be placed to prevent that.
My 2.2 shift is very short but I have to use some force to put it in 5th.
The system in my 1.6 is less short shifting but it feels more natural.
I think both cars wil have the modification with the extra rod.
Maybe I can place this on the chassis to prevent vibration.

Make sure it has a low Shore value in the "A" scale. Lower numbers are softer. Too hard and it will not dampen the vibrations much.

No one should do this to the Murena long gearchange rod.  That rod does not rotate about its axis.  It has to swing sideways as the attachment at the base of the gear lever moves from side to side as you go across the gate.  By restricting the long rod with a clamp like this, it can only put a strain on the system as it cannot move in the designed way.  This type of clamp would be fine if the long rod rotated on its axis but it does not.

Indeed, its a bit tight as I said.
I'm still playing with it.
So far this feels best.


I'm also busy with this.
Another weak point with lots of play.
{Note: don't know if it fits Murena!!!!!!!!}

The bush in the collar is a bit short.
Therefore it's getting oval.
This modification will help a lot.
