Its the same set up as I had since I fitted the Toyota box 2 or 3 years ago, so it's well tested, in fact it's the same as when I had the Alfa box.Originally Posted by LM mic
The grating sound is when I press the pedal- without trying to select a gear... Sounds to my engineering ears like the bearing - it doesn't sound fixable without spares and it's an engine out job. If I knew what I needed and had the parts, it's a days job......
Damneeeeeeeeeeeeeeeeeed ! ouchhhhhhhhhh
Bon courage mon ami !
OK So Spent the last Hour and a half In the Garage - The car needs spare parts to make it better & that just isnt going to happen before tomorrow, so sorry Guys no way I will be at Curborough..
Having Changed the Clutch Fluid Completely and Bled the Circuit, Still no gears with the engine running, But no problem to select them with the engine stopped.
Removed the cover from the Back of the flywheel & checked - yes the clutch is clearing, both plates are free. Tried gears again - no chance - Car Is on stands, so started the engine in gear & managed to go through all the gears reasonably well, but with some strange noise from the clutch...
Checked the Clutch disks with the engine stopped and in gear & clutch pressed & hey presto problem found - The clutch plate nearest to the flywheel is no longer connected to the gearbox input shaft. So either the input shaft spline or clutch plate spline is damaged or the hub has come detatched from the plate... Its not possible to see that unless I strip it all down, which is a good days job, so it will have to wait until I am back from work, as I am away again next week
Wowwww what a shame after all this work done onto your engine !!!!!
Do you confirm having only 2 disks ? Don't you think taht with that new power ( 550 hp ?) you need now 3 plates and smaller diameter clutch
What brand are you using Borg and beck ,AP or Tilton ?
Its very Frustrating!
Clutch is a Tilton 7-1/4" twin Ceremetalic Paddle Clutch Rated for 600lb/ft, so should be ample. & Currently I am only running 0.9 bat, so 470BHP 380Lb/ft...
I dont think I have enough space for a tripple plate clutch. I have never been fully happy with the clutch, so may try something different...
Sh*t Neil................... forget the gearbox just install Warp Drive !
Dr Spock
Sorry to hear about your woe's
Sorry to hear about the problems Neil hope you find a solution before the next track day is sorted.
Finally manage to get the engine out of the car to check the clutch.......OK So Spent the last Hour and a half In the Garage - The car needs spare parts to make it better & that just isnt going to happen before tomorrow, so sorry Guys no way I will be at Curborough

Nothing too serious wrong - the inner clutch plate was the wrong way round
I had had trouble getting the clutch plates aligned when I fitted the gearbox & had to remove and refit the clutch assembly a couple of times to be sure I had the alignment correct, of course the last ime it came off, I dropped the inner clutch plate and was focused on the spline alignment & missed the fact that the clutch plate was teh wrong way round.. Poor excuse, but its teh best I can come up with!
The Flywheel and Clutch cover are both OK. Both clutch discs are about half worn, cover plate is warped, so I just need a new cover plate, floater plate & 2 friction discs. I can also see that now the clutch plates are worn that the hub is just touching the flywheel bolt heads, so I need to take 0.2mm off of those to be sure there is no contact even with a fully worn out clutch.
Hello Neil
this why when we received from new clutches (years ago !!!) we painted in red all center discs in order to be sure in case of disassembling on pits kickly a gearbox and clutch there was that red color to remind not to flip over badly the discs !!
Are your bolt heads enought thick to be machined without compromising stethness ?
Just been and looked at the bolts. I have some bolts (not fitted) with 6.6mm thick heads, the ones fitted now are 6.2mm , with a 0.5mm lip around the top, see picture. I dont think removing that would compomise strength.
