MG Midget and Sprite Technical - Concentric slave for Antec Motorsport bellhousing.

I have an Antec Motorsport Engineering alloy bellhousing to put a midget 1500 Gearbox on a 1275 engine. I'm not going to do that but it's halfway to an A series engine to Ford type9 gearbox, I just need the Midget 1500 gearbox to Ford type9 converter which is not too costly.

There is no bracketry inside for a conventional clutch operating lever but there is what looks like an adaptor made for a concentric clutch slave cylinder.

If you look at the attached image maybe you can identify whether there is such a slave and who makes it. I know it is not the SAAB 900, the angles are wrong.

The angles and dimensions are approximate.

Have a look and see if you can identify it for me.

Looking around on the web it seems to be the same as AP Racing CP6859 concentric slave cylinder. Anyone know if it is based on a commercial slave cylinder? Ford maybe?

Go to Burton Power they list all of the parts you need for the Type 9 conversion concentric and their kits are excellent. We use them on K Series and Zetecs on our Minors. Do not use the Rally Design one, it has proven somewhat unreliable

I'll have a look at Burton Power and hope I find a suitable slave at a reasonable price.

Don't want to have to go back to square one with this.

I found this website who have the Tilton 1000 series slave cylinders and a drawing showing the angles I want. Interestingly, they say

Typical Application: SAAB 9000 Type Pattern
Mount: Interchanges with AP Racing CP3859 and CP6859

So looks like I will be looking on line for SAAB 9000

I used the Saab 900 one in mine

It looks like genuine Saab ones are on the 'bay for just over 50.

I had issues due to my tightening skills being inadequate after five or so years of hammering it :(

I would still use a Saab one again 'cos fitting a Ford one was not as easyl, the SAAB one has easily connected pipe fittings unlike the Ford ones which I used

Whichever you fit make sure you use Loctite on the fixing screws

I admit I enjoyed the messing around to make mine work, most normal people would probably prefer a bolt up, close up and forget it experience

For my next one I have a Vauxhall Zafira single pipe fitment type to play with

I hope I dont have to

The photo looks more like the mount/ oil seal to replace the nose piece on the T9, rather than the concentric slave itself. But you probably know that. Unless it is just the angle of the photo which is hiding the slave part?

The bell housing was intended to put a Midget 1500 gearbox on a 1275 engine and the photo shows some sort of mount with an oil seal in the middle. Presumably for the later 1500 gearbox with a proper oil seal or just for peace of mind if an earlier 1500 gearbox was used.
There is nothing inside and no access hole for a conventional lever arm type clutch arrangement. The mount has 3 holes with angles of 105, 105 and 150 degrees between and matching threaded holes on the inside of the bellhousing. As I have now found out the hole pattern is the same as the SAAB 9000 (not 900) slave so I think it must have been deliberate but won't know till I get one.

I'll post a pic later. I'm in the garage wrestling with a Frog!!

A picture of the internals of the Antec alloy bellhousing. Note no way for a conventional clutch operating lever to be installed.
