F-ing clutch has let me down again

terminal slip at usc today, coming of the line it spins then goes into slip in all gears

i either have dodgey comonents or i must be doing something wrong in assembily

everything was new on my new engine bar the flywheel, ap rally plate grey and new steel backplate

Did you have the clutch properly adjusted - ie the arm isn't hard up against the 1/4" (7/16 spanner) adjusting bolt on the flywheel cover?

Did you use two (six total) driving straps or three (nine total)?
Did you machine the backplate lugs to 23.5mm as reccomended many times?

If you used two straps, AND did the backplate mods, then you simply need a double grey as you have more torque than even an 'optimised' single grey can handle...

me and kean both machined our backplate lugs down to 23.5mm the week before Avon park as keans slipped at 15psi. After it was modded and the spring sat flat the clutch was a lot lighter and no slipping at 165lb/ft for me anyway.

it was adjusted correct Dave, i use 6 straps and nothing has been machined, i will strip it all out this weekend and start again

right going to whip the clutch out tomorrow night

whats the best way of machining the lugs? stick it in a lathe ??

iether a lathe or a milling machine

"Can I legally marry people now that I am ordained in the Church of the SubGenius?" aka i know jack sh"t

i also make things

i love coming home to chrome

sorry to sound stupid but what do you gain from maching the lugs?
how much would it cost?

cheers

enter 23.5mm in the search field, tick the 'thread body' box, and there are several posts about it.

I had to run my grey with the bolt wound into the arm - to get enough clutch movment to disengage :S

I never did work out why!

i've always had grief with mine. I bought all new clutch components arm/slave/plunger/pins etc and still couldn't get enough travel on it. ended up jamming 2 nuts inside the slave to get the throw i needed.

covers all the usual stuff...

The pushrod length check is always my first port of call in any dubious clutch shenanigans...

Metro turbo weekend driver,Mini turbo in the making again!

its all stripped out

should i replce the plate? it looks in good nick (should do for only doing 50 odd miles)

could it slipping have caused any damage? also how do i check it really is the AP race/rally over the Rally/road
the plate is a little shiney and has a far amount of dust in the grooves

plate should be ok.

just carry out the usaual checks.

on the not enough throw issue

check clevis pin on the pedal for were and make sure you have only about 10 thou of adjustment on the bolt and no more.
plus give it a good bleed.

always looking for them bigger bunches of bannanas

I made up an adjustable pin as mine had worn down, one of those things you end up having to do to get to work the next day.

Also My Wok is heavily vented, so much that I can see the release bearing, I just wind out the stop until the bearing just starts to spin. seem to work so far, but that is on an orange plate though.

The AP organic road/rally plate (the best) is dark charcoal grey - the 'road' one is a shiny biscuit brown.

Best not to have the throw out stop wound out so far as to have the release bearing spinning all the time, this will lead to failure of the bearing in double quick time!
