But how will bending the fork give you a longer throw? It'll relieve the pressure on the piston all right but if the pivot and points of contact remain the same so will the throw.

throw was only too short with shorter piston,with original piston i just need to relieve the pressure on the bearing.

bending the fork will hopefully give me that and enough throw to engage gear.this is no black and white solution as when i spoke to mark at lateral on friday he said there is no way i should have fitted a 5 speed kit in a 6 speed gearbox

I have heating equipment at work. Workshop is the next farm up from AVA behind Glasgow airport. Can be organised for you to use it on a Saturday afternoon.

stewart if i cant get anything sorted before saturday i might just take you up on that offer,thanks

[colin_ross]

I think I see what you're getting at.

You want my spare fork so you can bend two of them at diffeerent angles and see what works best?

Just give me a PM mate. Plenty of tools and equipment use there.

[fai17]

trying to bend it in situ may prove difficult as there may not be enough leverage.

i hope it works out for you Jimser

If an Agricultural workshop cant bend it, then he's no chance thats for sure!

again colin i appreciate the offer,i've got a spare 5 speed fork here which i've compared to the 6 speed fork which looks like it would make matters worse,which makes the whole episode even more confusing.i must admit though if this gets the better of me then it will be a first!i suppose none of us are invincible after all lol

If i'm reading this right it sounds like you have reduced the throw the slave cylinder can move, therefore the best solution would be to get some 5mmish thick flat bar and drill 4 holes, two for the gearbox casing and two for your slave cylinder. This will allow you to position the slave cylinder in the correct position and give a slight clearance needed for the clutch release arm, which will stop the clutch slipping, but will also allow full travel for the clutch slave cylinder, so that the clutch releases enough to engage gear. The plate will have two holes for the slave cylinder above and further back from the two holes used for the gearbox casing. Keep the two drilled and tapped holes for the slave cylinder as close to the gearbox casing holes in terms of height as much as possible.

Ignore the bracketry surrounding the cylinder, that's for a Giken clutch which has the cylinder reversed, but you get the idea.

[nanaki]

you know as much as it amazes me that people on here come up with weird and wonderful solutions to problems... I find it even more incredible that most of you mad lot seems to have a picture gallery of every engine part, mod and bodge job available.

Onward with the hardcore!!

I'd just like to know what it all meant!

But not to take away from your point; amazing what people know.

thanks for the input alan,after much deliberation tonight i've decided to cut my losses,take the 5 speed clutch out while it's still got value and buy the right clutch for the job.mark(lateral)reckons i'd be on the limit with this carbon clutch anyway so i'm going to get this sorted once and for all and have a bit of piece of mind.just don't think any of the other solutions were going to be 100% right long term.thanks again

jim

ps.twin plate carbon 5 speed clutch for sale shortly if anyones interested?

What's the twin plate carbon rated at and what's recommended to change it to?

He is changing to a 6 speed clutch like on mines Alan.

[AlanG]

Certainly the larger diameter clutch of the 6 speed can help future proof for further mods, but that bracket is sold by RCM now to counteract the issues Jimser is seeing. The 6 speed that went into mine after i sold the car still had the 5 speed clutch in it.

The only reason the clutch in there just now is slipping is because the release fork has been putting pressure on the cover plate continually.

As an aside the 1/4 mile times could have been even better if that problem wasn't there!!

Does that mean that clutch plate is not fully engaged with the flywheel thus less friction and less power?

[AlanG]

Yes, a bit like driving with your foot on the clutch
