Clutch Spec and Internal Slave Cylinder info help needed for Southern GT40 - Quaife Gearbox

[Jay Gadsby]

I've found a local Radical race team to do some work on my SGT40 - 4 miles away, so I'm very happy about that.
The Quaife gearbox is a lot heavier than I anticipated, to do it myself!

It's going to be a straight swap for Quaife's latest version and they are asking me to source a replacement internal slave cylinder.
Also, I'll be asking them to replace the cutch at the same time.

When dismantled, the clutch kit is almost certainly going to be the AP Racing one so that's my first question.
I've looked through previous posts and have only references to the GTD AP Racing clutch but that's with the UN-1 Gearbox.

1) Does anyone have the clutch part numbers for the SGT - Quaife setup?
The bellhousing is the John Wisher version, not the Quaife one if that makes any difference.

2) Second question, is there a "go to" internal slave cylinder that would be fitted or would that be down to personal preference when sourced?

They've asked, and I'm hoping to get an idea of what I need to source for them to keep their workshop free, as far as is possible for their own needs.

Thanks in advance, any help would be greatly appreciated.

Hi Jay

Am now awaiting delivery of my Quaife ZFQ to go into my GTD to replace my Renault gearbox. Expected within the month. I plan to use an external clutch slave cylinder as easier to maintain and manage going forwards.

Yes, external has advantages.
The guys doing it for me don't want to stall in the middle of the job with a faulty/leaking internal slave.

Jay I believe this is what you need, I have a Quaife, the part number I have for the slave cylinder from Merlin Motorsport has changed but on further searching this looks the right one. I made a packing plate to line it up and works well. They come in LH & RH versions

Thanks for looking into this for me.
The slave cylinder on mine is external and not internal, as I originally said.
The existing slave cylinder is now going to be reused.
The gearbox is out and the new Quaife QBE62G is about to go in.
Mick helped us out with the parts identification as per when he built it and big thanks to him for his ongoing dedication and advice.
I'll be getting Quaife to recon the original one so it's ready for a second life.
Here's a couple of photos of the progress so far, thanks to some great guys.
