Gearbox rebuilder in South or South West?

Hi,

I need to get my C2 gearbox rebuilt as I am fed up with the crunch into second gear when cold and the slack and clunking in the overall drive train on when on and off the power. I have worn drive shafts too, but with the car jacked up the excessive play is visible when you manually turn the rear wheels slowly clockwise then anti-clockwise to take up the slack when in first gear. It extends into the gearbox much more than I think is normal and is not just due to the worn CV joints.

The car has done over 170K with no history of a rebuild, so its probably about time.

I will get my local garage to remove the box and I would like to know if you have any recommendations for where to get it overhauled & rebuilt?

My closest Porsche specialists are JMG Porsche in Bornemouth and Canford Classics, but would like at least 4 to contact.

Any suggestions?

Have you tried Eddie at Silvertune in Christchurch. He's my preferred in the area.
Mines probably due a rebuild so I'd be keen to know how you get on....
 
What are my replacement options? I expect a replacement box if available from Porsche at all would be far too expensive, but are there any reputable Porsche Gearbox refurbishers out there that anyone has experience of (directly or indirectly)?
 
Unfortunatley none local to you, Unit 11 did Trev's gearbox, Cath Burrows knows her way around them and http://www.mbporsche-engineering.co.uk/ have a good reputation, a bit closer Tuthills https://www.tuthillporsche.com/

I have rebuilt a few in the past and if you have the right tools it's pretty straightforward, but they weren't Porsche gearboxes.

Hi Jan

Try Williams Crawford in Saltash, just over the Devon border in Cornwall

They do a lot of renovation work

https://www.williamscrawford.co.uk

They're not particularly cheap tho'

Do they actually do the job or outsource it someone else? I was always under the impression they use other people in the renovation and are more caretaking and over-seeing the job rather than rolling their sleeves up and doing it themselves. But I could be wrong and they have ventured into a new area of repairing and rebuilds. An earlier post mentioned Unit 11 and Cath Burrows both of whom are in the North-West - both very good and Unit 11 is probably the go-to guy for air-cooled Porsche and Cath is certainly very good across the range.

You may be right about that, I was at an open day there recently and there were a lot of stripped down engines and gearboxes there. I think that if you have a chat with Richard Williams, you'd get a straight answer, what I have noticed is a large proportion of their new warehouse is dedicated to sales, not unlike JZM who have also gone in that direction. However they do have a restoration section so I would imagine they have quite a lot of expertise on site
 
Thanks to those who have replied so far. I have sent off for estimates from a number of specialists and popped in to chat to my local. Now learning some new words like "Lash", and inspecting my old photos of the drain plug magnet to determine the shape and patena of the filings and shards found the first time I changed my gear oil about 3 years ago!! Thankfully there was hardly any filings in there when I changed the oil again a month or so ago and I think those are purely due to the crunching into second.

Some feedback has suggested I might have a worn diff as well as the synchro going on the first to second gear. Strange thing on that last issue is that it only does it on the first or first and second gearchange on a journey from cold. Which is like the oil hasn't been thrown around enough or something weird as once its warm there is no problem. I have tried two different oils of the recomended viscocity and its not as if the South coast of England gets very cold - so that is an odd one. Mind you now I am typing this I have thought that if its something like a heat problem, maybe somethings expanding when it warms up and the problem goes away as a result. That sounds more likely than the oil type as why wouldn't all gears have the same problem when cold?

here are a few photos to keep you interested. The shards are from the last 3 years driving.

This one is on the sump plug when I first got the car and did a gear oil change (Thankfully the second oil change was much healthier in comparison).
