RS2000 sump & heavy clutch/poor alignment
I've got money on Flak being the first to answer this one…..
I fitted an RS 2000 sump to my pinto a while back, the mount for the cable that operates the clutch does not align properly with the clutch release
arm, causing a heavy feeling clutch (with the old sump it was smooth & light). I've looked at the release arm for the RS2000 and it looks no
different than mine (although it could be longer, I haven't measured), only conclusion is that it must be a difference in bell housing design to
allow it to exit in a slightly different location. Am I correct?
Options;
1. buy correct bell housing?
2. bodge/fabricate a plate that bolts to the clutch arm to allow better alignment, it might cause other issues as it will now be pulling on the side
of the arm rather than centrally causing it to try and rotate.
3. connect the cable up backwards so that the sheath goes against the clutch arm and I bodge/fabricate a new mounting point on the sump to hold the
end of the cable.
4. any other suggestions, I can't be the first to have noticed this problem
Cheers
Alex

Well since you have money on it.
This is from a very vague recollection of an old conversation so:
The release arm for the RS2000 bellhousing is slightly different to the std pinto one, if I remember rightly it's slightly longer because of the
different design of the bellhousing. So it could be this thats causing the problem.
I am using a chopped steel sump, so have no direct experience here.

cheers fella, I though the housing was designed differently as well as being made out of ally rather than iron.
A longer arm would make sense with the alignment and also the use of a heavier clutch in the RS2000, I know they used a different cable as well to
cope with the force.

The RS2000 alloy housing has 2 starter motor bulges in, so yes it is a different design as well as being alloy.
Someone will no doubt be along to give you a definate answer, as I say this is a vague recollection.

Currently stugling with a V6 Type 9 gearbox to Pinto via RS2000 bell housing.
I have used the RS2000/Cortina clutch release lever with a modified thin metal dust cover and have put the black Granada 55mm pull clutch pawl and now
have the correct movement. Before i only got to the pedal bite point and it felt awfull. I am now trying to move the bite point earlier in the pedal
movement with spacers at either end.
I may have to remove it all and use a longer clutch release bearing. The one from a Capri, Quinton Hazel CCT133 is about 9mm taller.
My problem may be a little compounded by the 30mm spacer to reduce the longer input shaft on the V6 box.

Post how you get on especially if you try the longer release bearing. I also have some photos of my mods, email me or usu with and address and i will
email some over.
Further bits of info, the sierra release leaver is to fat at the neck, the V6 one is the right width at the neck but too long, the RS2000/cortina one
fits but the clutch cable attachment is flatter than the sierra one, so more movement at the pedal needed before it bites

After reading your problem again I thought i would try and answer using another reply......
RS2000 sump with standard bell housing.
Standard bell housing has a cast in boss for the clutch cable and i assume that this is now covered by the cast plate on the sump. Easy mod is to
drill out the flat plate so the cable can go in to the standard bell housing boss.
The starter motor positions on the RS2000 bell housing are slightly higher than the standard bell housing so you will indeed have a clutch cable boss
to lever mismatch.
Changing the lever to one not designed for the bellhousing is probably going to compound your problems.

You are correct about the built in boss, the sump wing is actually in the way of this and would prevent it being drilled out, I had however forgotten
about this boss (within the bell housing), and think that I can mount the nipple end of the cable within it easily and the sheath part through the
clutch arm. Kind of my option 3, although I had no idea of where to mount the nipple.

You will then be using the clutch cable outer to pull the release arm? I think i would put on a short steel sump, much easier. Infact you should give
me your ally sump in exchange for my short steel one
Although that would mean me pulling the engine and box for the Nth time.

I wish I had gone for a shortened sump rather than the alloy one, the irony is that I though I was doing it the "proper" way by buying the
original part, didn't realise there would be other bits needed as well.
