Gear Linkage Wear

[944 man]

My gear change is terrible. Its imprecise and whenever you move across the gate you cant be certain that it wont hang up, no matter who careful you are.

Can anyone suggest which levers, bushings and such will probably need changing, please?

We can bulk buy, I'm going to do mine this winter.

I can never get 2nd (on the way down), Tom can hit it sometimes but I always end up in forth.

I loose a ruck of time getting out of the slow corners.

I'm not far from Sheffield, i'll come over and help you do yours, for the education.

I have exactly the same - change down to 2nd is awful even with double de-clutching....... would be interested to know cost and time taken to sort once you have had a shot at it as I suspect there is no way I will get to look at it till the Winter, especially as my old idling problem has returned with a vengeance, seemingly with the sunroof stopping working at the same time !

The two places it can develop 'wear' are shift pin near the gearknob (1), and the joint at the back (2).

(2)

In my experience the shift pin causes the most play, and easiest to fix. So I would tackle that first.

You can replace the part.. or repair it. I repaired mine, as I think its tighter than replacing with a new part.

Follow this guide to the part where you remove the old gear shifter http://944foot2thefloor.blogspot.co.uk/2010/06/how-to-remove-and-replace-worn-gear.html

Once you have it removed, use an angle grinder to remove the pin so the shaft is completely smooth.

Use a 10mmdrill bit and drill a hole where the shaft used to be.

Replace with a 10mm bolt, a couple of washers and a locking nut.

Replace the whole lot and tighten up the bolt just enough so it doesnt have any play, but isnt too tight to move the shifter.

The plastic cross piece also can wear quite badly too, i think the whole rear linkage is around £110.

 

[944 man]

Thanks for the offer Gerry. I suspect that it may be the rear, because I believe that the car has had a new lever already, I will have to ask Jeremy.

If its rear I would suggest buying the short shift kit, they are rose-bushed and are about the same price as the standard part.
Although whatever you do don't buy the Deutsch nine manufactured one, its terrible quality.

Thanks Nick, and for the previous post also.

There is a guy selling the plastic bushes on e-bay he makes them out of "something" harder wearing. Should be easy to find. They go for £25 or so.

Good thread. I've never been that happy with the gearshift on my S2, but believe that that the problem is due to significant wear in the linkage mechanism at the back on top of the gearbox. When I had the 'box off to change the clutch I was amazed at how floppy everything there was, and had I had a couple of hours spare I would have made a replacement linkage. Sadly I was in too much of a rush to get on with the clutch job and didn't do anything about it, but have it on the list of things to do 'some day'.

Changing the whole lever at the front seems excessive given that the problem is just slight wear on the pin. Surely it wouldn't be hard to knock up a replacement pin, and bolt this in place of the old one? Some reasonable quality steel stock and a small lathe and you'd be away.

Just re-read this post from Nick and realised he is suggesting the same as I did ... does this work Nick, just using a bolt rather than a smooth shaft?

Well I said bolt, but it wasnt threaded all the way. I think it had a 30mm shank.

You could actually tack weld the bolt to the shifter if you wanted.

Hi Simon,
yes I changed the Lever end last year, you should have felt it before!

But...after driving a DB9 and a BMW M Coupe (Breadvan) I found the 944's gear change much nicer/easier than both!

The 968's isn't much better
