    D1 Clutch booster

    Hi,
    Does anyone know whether a clutch vacuum booster can be fitted on a D1. The heavy duty clutch is a bit of a pain to use.
    Thanks
    Brian

    In theory, you could fit an inline remote booster.
    I normally use a VH44 or similar to boost drum brakes but that might be overkill for a clutch.

    You could contact Hydroboost & see what they suggest for a clutch:

    You'll also need to make up new clutch pipes to suit & tap into the vacuum system.

    IMO Nissan Patrols have a boosted clutch master, try a 4WD wrecker for ideas.

    VH44 has been used succesfully on Td5 Defenders, your Tdi clutch shouldn't be all that hard, how much heavier duty than standard is the pressure plate?

    I would be worried about the lifespan of the pivot ball vs clutch fork too.

    JC, exactly what I'm thinking. I am very worried about the clutch fork longevity, although I put a new one in with the clutch, there's not a lot of thickness to them.
    The clutch is an Xtreme Outback unit rated at 450Nm. They said it wouldn't be noticeably heavier, but hell it is. Way overkill for the tdi. My wife is struggling with it, bless her, so I might go the VH44...

    Mmm, Brian I would be worried about the fork, the Td5 and V8 have cast iron forks, come to think of it, I wonder if they can be retrofitted? I may have to look into that. Meanwhile, be prepared to maybe pull th etrans in a year or so to check on it
    The outback clutches are pretty good, Exedy plates etc, but yes 450nm is Very high
    I'll do some research about the cast fork possibility.
