Ok when I got the car I was given a brand new TVR heritage OE clutch slave with it as I was told although the clutch and slave arm etc was replaced last Oct the clutch slave was aftermarket with a slightly smaller bore meaning a heavier clutch feel , and that fitting this TVR one with bigger bore will provide a slightly lighter feel

My question is how easy is this to fit ? As I will need to change the whole thing inc the pushrod as it’s bigger ? Is this straightforward to change to remove pushrod from clutch arm ?

One of the most simplest of jobs.

Just two 13 mm bolts, bolting the slave cylinder to the Bell housing.
Disconnect and reconnect one hydraulic pipe. Bleed the system on completion, (drain all the fluid out as it probably needs renewing).

Thanks Phazed this bit was straightforward it was more the pushrod change ? As assuming most slave changes people simply leave the pushrod in place and change the unit itself, I can’t as the pushrod is a different size and again I’m assuming the pushrod is fixed in place at the arm end ? Unless it’s simply pushed through ?

I have used the same pushrod with both sized cylinders. It is only a pushrod with the ball type end that fits in the slave cylinder.

If you need to replace this it held in place by a little plastic clip on the fork and can be done in situ by feeling around through the aperture in the Bell housing.

Do I assume from your comment that your new slave has a pushrod fitted to it?
If so then it is the wrong item.

The pushrod attaches to the clutch lever with a plastic clip. the other end is just the rounded end of the rod. this end just sits in a cup in the slave piston.
So as has been said 2 bolts to remove and replace.
So you are aware, when you fit the new cylinder the piston has an internal spring so at first you think that it won't fit. You locate the rod in the end of the piston and then press (quite hard) to push the piston back into the cylinder until you can get the first bolt in (which you need to have handy before pushing the cylinder into place.

Ok starting to make sense so my slave the rod is separate to the cylinder in the bag it came in so two pieces

From above are you saying I can leave the rod in place on the car and just swop over the actual cylinder? I assumed the rod was matched to piston size and the rods would be different thickness but makes sense that the piston is inside the cylinder and the rod pushes the piston as if can leave in place it does indeed look very straightforward!

Could you confirm as above that I can just leave the original already fitted rod as is and fit the cylinder and not bother with the new rod ?
