how can i convert the hydraulic fork on ml5t gearboxes to cable? ive been looking for ages and cant see any logical way of doing it...you cant just change the arm over because it doesnt have an arm, its hydraulic so works off a cylinder and hoses etc. cheers ________________________________________ 309 GTi6-T |

Can you not just drive a hydraulic master cylinder with the cable?I'll just see if I can find the pic. ________________________________________ Ex SC-6Now in a Megane R26 |

that doesnt make sense. The end thats bolted to the cable arm is the end that pushes the fork isnt it? im struggling to see how the fork can be pushed in the right direction to push the release bearing into the pressure plate? It needs to go like this (up at bearing end, hence pushing bearing onto the pressure plate, and down at the other end.  i cant see how this is achieved when the hydraulic thing doesnt even connect to it (even originally) it just sits in a ball sort of thing... ________________________________________ 309 GTi6-T |

the best way to go is convert the pedal box to hydraulic, too many parts to flex, break and go wrong combining the both. I converted a mk2 escort pedal box from cable to hydralic and it wernt to bad to do. If you have to fabricate parts anyway then why not fabricate the pedal box to make it all hydralic |

whip the pedal box out of the car and have a look, there will be plenty of fabbies that will have a look at it for you, best to rob the master cylinder from the 406 too and have a look if you can use that |

i hate hydraulics aswell  i know it pulls the bearing out, but i cant see how that disengages the clutch? could i not simply rig up an arm to the gearbox casing that accepts a cable type, then connect that to a pole which pushes the fork down hence pulling the bearing away? ill do a paint sketch in a min and show wat i mean. ________________________________________ 309 GTi6-T |

easier to pin the clutch fork to the shaft, then extend the shaft out through the top bush and make an arm to go on the top.then attach the inner cable to the engine and the outer cable to the lever to work jsut like a gti6 pull clutch. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

that just came to me now, can't think why nobody has done it yet either easy enough to get some high pressure small bore hydraulic hose made up to suit. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

ive already thought of that, but unfortunately theres no space because of the cable gear arms which are near enough directly over where the shaft would be extended out  in cabin way would be too much effort and moneys. i want a cheap solution  check this mofos  ________________________________________ 309 GTi6-T |

no chance, there is a serious amount of force required to operate a clutch and that will flex and break, why not concentrate on doing the job properly. If you ae going to the lengths of fitting that box why are you falling short on the clutch side of it |

maybe  pretty much how a BE1 box works actually oh, and as for the cable linmkages, there is enough room, that's how AdamB and Goliath sorted theirs, adam's needs a little more perfecting, not sure about Georges one. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

agreed, but if i reinforce it enough will it see me good until i have time to properly set it up using hydraulics etc? its only got to last a short trip down a38 and a rolling road session to prove the power output then it can stay on drive until i have time to fig around with hydraulics.________________________________________ 309 GTi6-T |
