Gearbox shift pins
Gearbox shift pins
My 3.0 Z3 is having a new clutch fitted on Thursday. I was wondering, is it worth asking them to replace the shift pins while they are at it?
The car has done 56,000 miles.

Wow that's not far for a clutch
Re: Gearbox shift pins
Does the lever return to 3/4 from R, 1/2 and 5.
If so, the shift pins are OK and should be left alone.
If not, it will be cheaper to do it when the box is out than to have it done as a specific job.

Thanks for the reply, yes it does.
So one job l don't need to do.

Re: Gearbox shift pins
The clutch was not worn out, but had drag. When they took out the old clutch it turned out to be 50-60% worn. I am not entirely sure of the reason for the clutch drag, but it's fine with the new clutch fitted.4wheels wrote:Wow that's not far for a clutch
Re: Gearbox shift pins
Once you have excluded everything outside the gearbox, the best solution is to do what you did.
Change everything inside.
If you are DIYing and can afford the time and space to have the gearbox off the car for a prolonged period (and possibly many times), you can do some investigation and save some pennies, but if you are paying garage fees - change the lot. It will be cheaper in the long run.

Re: Gearbox shift pins
Can you clarify that test? Engine off. Put it in Reverse, flick it out and it should come to rest in positions 3/4. Same with 5 and it comes to rest in positions 1/2?pingu wrote:Does the lever return to 3/4 from R, 1/2 and 5.

Sorry, might be being a prat here.

Re: Gearbox shift pins
It's not really a test, it's just whether the gear stick returns to the centre (between 3&4) when in neutral. It's the normal behaviour of any manual gearbox.mrscalex wrote:Can you clarify that test?

Re: Gearbox shift pins
But is it a valid way to check if the shift pins need replacing? If so it sounds like a good test to me if it saves pulling the gearbox out to checkBladeRunner919 wrote:It's not really a test, it's just whether the gear stick returns to the centre (between 3&4) when in neutral.

Re: Gearbox shift pins
The point I was trying to make is that if the gearbox is behaving normally, the shift pins are ok. You'd notice if they needed doing, rather than needing to perform a specific test.
Re: Gearbox shift pins
Okay, got you. Mine knocks a little on every change. But I suspect that's the diff mount or possibly the giubo.

If you can live with the fault - great. Because the solution is costs around £100 if you DIY and around £300 for a garage to cure (£500 if they change the clutch as well - which I would recommend unless it's brand new).

That sounds like a mounting (engine, gearbox or diff) or the giubo, or loose propshaft nuts (very unlikely unless they have been touched since new).mrscalex wrote:Okay, got you. Mine knocks a little on every change. But I suspect that's the diff mount or possibly the giubo.

Re: Gearbox shift pins
I changed my shift pins two years ago at 30000 miles. To cure a very notchy gear change. The result was an extremely smooth change, well worth the £48.00 I paid for the new and modified pins and bushes. With the gearbox already out it is not much of a job, but a set of bush insertion drifts are required these are easily manufactured if you have access to a lathe. If not you can borrow mine. I have a post somewhere on this forum covering this job.

Re: Gearbox shift pins
I did my shift pins, springs and bushes last year while I had my gearbox was out. I didn't have a set of the drifts, So I used deep sockets to gently tap in the bushes. Worked fine.
My gear change is now 95 % better than before.
