    Default 4A to W series clutch fork and throwout

    Hey guys, I know there's a thread here somewhere outlining this but I've run into an issue.

    I'm using a W55 for my 20v conversion and if I remember correctly, the thread I mentioned above stated that you use the W55 throwout bearing and clutch fork. However, my clutch fork which is apparently from the W55 doesn't fit the throwout bearing I received with the gearbox.
    The fork doesn't actually fit around the throwout bearing when trying to match them up in your hands and when inside the bellhousing, it's too short to reach the bearing...
    The only explanations I can come up with are,

    A) I've been given the wrong clutch fork.
    Or
    B) I need to use a 4AG/T50 clutch fork.

    If anyone can let me know what they've used for their setups, or can shed any light, It'd be greatly appreciated.

    Cheers

    Depends on what bellhousing you have ? ,mine with a niteparts bellhousing is using the 4a fork with the w/series bearing/carrier with a spacer between them(NPC clutch).niteparts do a bearing carrier to suit (wish i had known when i got the bellhousing)

    Apparently the toycoolrolla bellhousing from malaysia is supposed to use the w/series fork.

    i think the dellow uses their own fork & bearing carrier.

    What bearing do you have(is it 2 piece cast carrier with pressed on bearing or composite integral ?

    Thanks for the reply, man.

    I'm unsure about who made the bellhousing, it doesn't have any branding/lettering on it but it fits up nice.
    I'm also unsure on the bearing so I just took some pictures for you but the uploaders being retarded.
    It just came with the W55, are there two versions of the bearing that came with these boxes??
    Also, on closer inspection the clutch fork I have is definitely not for this throwout bearing, won't fit around it. I have a 4A/T50 clutch fork on the way, when it arrives, I'm hoping it's going to fit..I'll also track down another W55 fork and see if that works out.

    I'll keep trying to upload these pics in the meantime

    Cheers

    Yeah well it fits up really well so I'm happy with it. Just have to make a hole for the slave...All good though. Going with a Celica slave too.
    I might even start a build/rides thread. I'm bored enough haha.
    Thanks mate.
