Need to measure the discs as there are two sizes.

Maybe because there are two sizes as i mentioned in the OP and i need to measure them to find out which size i need?

Oh and yes before you wonder i did give the parts supplier the registration

Yes, I did read the post. Did you see mine? I asked why you had to remove the disc to measure it, not why you wanted to measure it.

What I mean is, surely you can get the outside diameter and thickness of the disc while it is still on the hub? Possibly a little more fiddly that way, I grant you, though not by the sound of it. And obviously you'll have the get the screw undone sooner or later, I just couldn't see why it has to come off to be measured. I am picturing the discs on my cars, wondering what's different on yours.

Heat the area up and use a good releasing spray on the screw. Make sure the tool/screwdriver fits perfectly. Sometimes i superglue the tool in to get an extra bit of grip.

Then smack the head of the tool and you rotate it. Does the same as an impact driver.

If it is really tight, put the ball end of a ball pein hammer on the head of the torx fixing and hit the other end of the hammer with another hammer to shock it. .

I thought everyone learnt in basic metalwork at school, never never never hit two hammers together. I suppose metalwork is no longer a subject due to H&S (all that dangerous machinery and tools)

Various articles on the net saying they wont shatter but chips may come off

If in doubt get a bigger hammer.

I had the same problem and just used a tape measure across the disc. Measurement didn't come close to either sizes but I was able to rule one out.

SteveJW, sorry to offend your finer feelings, but if he's taking rust welded components apart, I'm not the H&S guy telling him to put on his goggles to look out for (potentially) flying chips from hardened objects hitting each other.
Perhaps it will work if he just asks both components nicely to come apart and they can all be friends?

the sump plug on mine was done up with an impact driver. just counldn't get it of. I even pulled myself of the floor while holding the ratchet attached to the sump - still wouldn't budge.

I had a breaker bar and socket adapters, I put a 1/2" to 3/8" adapter on so i can attach the ratchet bit and undid the sump plug.

torx are made in socket sets to, so give it a go. just hope the torx is t25+ cos amy smaller the torx bit might just break off.

And if you can't fix it with a hammer it must be an electrical fault

Nah. If you cannot fix it with a hammer then you need duck tape.

I've never heard that one before. My trusty hammer [bought with Green Stamps [US version of Green Shield] in California in 1963] has been used and abused in all possible ways and has never lost a chip of metal.
