Garth Posted May 16, 2018 Share Posted May 16, 2018 Any ideas on best place to buy the original Ford part? Have spent hours on the net trying to find an OE version and cannot - plenty of other makes - FTE, Sachs, etc but difficult to know if they are any good? popped into the local Ford dealer and he can get me one for the bargain price of £256! Caterham web site only has the Duratec version which looks very similar but is longer - and also pricey? Link to comment Share on other sites More sharing options...
ChrisC Posted May 16, 2018 Share Posted May 16, 2018 So from the Caterham site it’s £124. https://caterhamparts.co.uk/clutch-parts/3666-clutch-release-bearing-sigma.htmlMy original part was a FTE unit in my 2011 car. Link to comment Share on other sites More sharing options...
Domus Posted May 17, 2018 Share Posted May 17, 2018 I have one in my garage, complete with braided hose and friction plate. Could be persuaded to part with them. Link to comment Share on other sites More sharing options...
Garth Posted May 17, 2018 Author Share Posted May 17, 2018 Hi Chris - I think that slave must be for the Mazda gearbox? It looks very different to mine - mine looks like this Duratec one https://caterhamparts.co.uk/clutch-parts/2221-clutch-bearing-assembly-ford-r400.html?search_query=clutch+slave+cylinder&results=154I have done a little reading and it would appear that FTE is a reputable manufacturer and if their website is to be believed they make OE parts for several car companies. Their slave also seems to be consistently priced across the various web sites I looked at - unlike many of the others!Peter is yours new? Have sent you personal mailCheers Link to comment Share on other sites More sharing options...
Ian Mackenzie Posted May 17, 2018 Share Posted May 17, 2018 Hi GarthI've just seen this picture, you need to look at a ford mondeo clutch slave cylinder, there are 2 different sizes (circa 10mm as you’ve just discovered, one for the 2l and then there is the one for the V6).I’ll have a look at my notes when I did the Duratec conversion as I used one of these….CheersIan Link to comment Share on other sites More sharing options...
ChrisC Posted May 17, 2018 Share Posted May 17, 2018 I have that one on my 2015 Duratec 6 sp car. The plastic one I had on my 2011 Sigma 150, which had a 5 speed Type 9 box, not a Mazda box, had part number Fomoco (Ford Motor Company) 7G917A564AC You can tell if you have that one if the braded hose for the clutch goes into the bellhousing at the side (near the starter motor). The Duratec one you posted a link for has the hoses entering at the top of the bellhosuing. Obvously if your bellhousing for you Sigma isn't a CC part all bets are off.

ChrisC Posted May 17, 2018 Share Posted May 17, 2018 I am confused Sigma or Duratec Link to comment Share on other sites More sharing options...
Garth Posted May 17, 2018 Author Share Posted May 17, 2018 Hi ChrisMine is a Sigma with a CC bellhousing, but they must have changed the slave cylinder as mine looks exactly the same as the Duratec one I posted! It turns out - as Ian says above - the Duratec and Sigma ones look very similar but the Sigma version is slightly shorter than the Durtec version!Thanks Ian will look at the rwd web site later.

ChrisC Posted May 17, 2018 Share Posted May 17, 2018 Ok - As I said my experiance is with a 2011 Sigma Type 9 5 speed, using this bellhousing https://caterhamparts.co.uk/bellhousings/3660-bellhousing-die-cast-sigma.htmlYou can see the holes for the clutch connections pointing towards the gearbox face near the bump for the starter. If you used the Duratec style CRB the bleed nipple would be impossible to access (although obviously you would be able to get the braided hose down the hole) because it point in the wrong direction. The pastic CRB has the connection and bleed nipple in the correct direction for these holes. I have only seen these two bellhousing options, Duratec and Sigma Type 9, So I assume your Mazda box?

Ian Mackenzie Posted May 17, 2018 Share Posted May 17, 2018 I feel the need for a couple of pics of Garth's set up..... Link to comment Share on other sites More sharing options...
DJ. Posted May 17, 2018 Share Posted May 17, 2018 When mine failed three years ago, I took the part to a Ford dealer and the parts man found a number on it. He had one in stock and it was £95. I'm pretty sure it comes from Focus/Fiesta with the 1.6 Sigm engine. Link to comment Share on other sites More sharing options...
Jim 123 Posted May 17, 2018 Share Posted May 17, 2018 Good point DJ, chances are that the slave assembly will have 7 digits on it. In Ford world this will be the FINIS code, and it may even come up with a Google. Gareth chances are that the part is sourced from Valeo. A polite call to their office in Redditch and you might find they can ID the part if you send a piccy and give a couple of dimensions. Most of this stuff is industry generic.

Garth Posted May 17, 2018 Author Share Posted May 17, 2018 I think I am now getting to the bottom of this... Will try and add some pics. First pic shows the engine going in in original spec - you can just make out the connections to the slave cylinder poking out of the bell housing. It would appear that when my engine was upgraded (and unbeknown to me!) they put in a different slave and just drilled a new hole in the side of the bell housing! I think this may be down to the input shaft on the gearbox being a larger diameter and not fitting through the original slave cylinder? See hole in side of the bell housing in pic 2 and 3.the bore of the my slave is 32mm - what is yours Chris? Link to comment Share on other sites More sharing options...

Garth Posted May 17, 2018 Author Share Posted May 17, 2018 Rather - has worked for years, so I guess is ok!? Link to comment Share on other sites More sharing options...
Ian Mackenzie Posted May 17, 2018 Share Posted May 17, 2018 Don't know the reason for the change, but I agree, if it worked before...it will work again...I'd stick with a like for like replacement for simplicityCheersIan Link to comment Share on other sites More sharing options...
Garth Posted May 17, 2018 Author Share Posted May 17, 2018 Have just looked up the details on the CC Sigma slave and it has a bore of 28mm, whereas the one that came out of mine has a 32mm bore.I am therefore assuming that they had to use a different slave because the input shaft on my gearbox was changed for a larger diameter one for some reason when BGH did that work!Just ordered an FTE slave online so lets hope it works! £100 including delivery compared to the Ford OE part which is over £200.

elie boone Posted May 18, 2018 Share Posted May 18, 2018 That looks like the Duratec slave cil. count the splines on your clutch or on the gearbox imput shaft and it may be 23 splines where as the Sigma has less than that. so it could be that you have a Duratec spec gearbox imput shaft & clutch on a Sigma.

Garth Posted May 18, 2018 Author Share Posted May 18, 2018 When I had the engine rebuilt I also got a new BGH E8 gearbox and I recall there was some issue with the input shaft. This is why I think it ended up being Duratec size! Will check number of splines when next at the garage. Link to comment Share on other sites More sharing options...
ChrisC Posted May 18, 2018 Share Posted May 18, 2018 So originally you had a Sigma CRB in a Sigma Bellhousing, now you have a Duratec Type CRB in a Sigma Bellhousing which has been modified to fit that CRB. So my Sigma didnt have a spaced behind the Sigma CRB, but my Duratec CRB has a spacer behind. Are you sure your CRB is not over extending? As for a replacement I think your going to have to google part numbers off the CRB you have fitted. But looks like you have done that already :) Link to comment Share on other sites More sharing options...
John Vine Posted May 18, 2018 Share Posted May 18, 2018 In case it helps....My original (2008) R400D CSC carries the Ford P/N 94ZT-7A564-BB. The FINIS code (not stamped on the CSC) is 1504696.The I/D of the sleeve at the gearbox end is 30.4mm, and at the clutch end (where there is a small lipped insert) 28.5mm.JV Link to comment Share on other sites More sharing options...
Garth Posted May 18, 2018 Author Share Posted May 18, 2018 Thanks JV - I am pretty sure that is the Duratec version which looks identical to the one fitted in my car, but is about 10mm longer! one on left is the Duratec version - other the old one from my car.This is how it all happened... my new E8 BGH gearbox was specified with a 'longer' first gear. This means they have to install a larger diameter input shaft - similar to Duratec version the larger input shaft does not fit through the standard sigma clutch slave cylinder (CSC) therefore when engine and gearbox work done the CSC had to be changed to one with a larger bore to accommodate the larger input shaft this new CSC looks very similar to the one fitted in Duratec cars, but is shorterMy remaining concern is that having fitted the old CSC and taken various measurements it would appear that even with the old CSC the pressure plate is preloaded by about 5mm by the CSC! I have spoken to Stuart at Premier Power and he says that they can machine the bellhousing to remove some material to make the extra space - will check this out on my next trip to the garage!Thanks for the comments guys Link to comment Share on other sites More sharing options...
John Vine Posted May 18, 2018 Share Posted May 18, 2018 Do the CSCs in your photo have Ford P/Ns stamped on them?JV Link to comment Share on other sites More sharing options...
Garth Posted May 18, 2018 Author Share Posted May 18, 2018 The one I took out does. That is how I identified the replacement I am getting. Elsewhere it had an FTE number so I have ordered an FTE one which is almost a third the cost ! Link to comment Share on other sites More sharing options...
