There are 2 types of bolt pattern to consider the older 6 bolt + dowel bug pack version and the 8 bolt + dowel SCAT although I think Bugpack are using the 8 bolt pattern now and most are all T4 bearing mains. Below pics are of a floater clutch for a 6 dowel bug pack crank (t4 centre main only) (http://im1.shutterfly.com/media/47b9dc34b3127ccec60b24c5f13d00000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) (http://im1.shutterfly.com/media/47b9dc34b3127ccec60ad01c50e200000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) (http://im1.shutterfly.com/media/47b9dc34b3127ccec60afeab504200000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) (http://im1.shutterfly.com/media/47b9dc34b3127ccec60a3685500800000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) (http://im1.shutterfly.com/media/47b9dc34b3127ccec60bd815f19300000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) (http://im1.shutterfly.com/media/47b9dc34b3127ccec60ba80df1b300000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) (http://im1.shutterfly.com/media/47b9df23b3127ccec651cc2ee6dd00000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) Title: Re: flanged cranks Post by: Andy Sykes on June 22, 2011, 19:21:15 pm thanks for the info :) i think it may be possible to machine but i think im going to wedgemate what ive got and see how it goes i will have clutch control so that may help

Thanks for that Doninick It's not that I'm Dyslexic you know, I just made a mistake in thinking that pic was of a Bugpack crank. But thanks anyway ::) Regds Title: Re: flanged cranks Post by: Rick Sadler on June 23, 2011, 19:34:33 pm The bearing kits we sell (#4000-70) is for the JayCee style center thrust set-up.

I spoke to Roger Crawford about this one and apparently the only difference between this and a newer one is that the new ones have red anodised covers. You can get two diaphragms to suit your style of driving - a heavy and a lighter and you can also adjust the pressure by adding/taking off washers from under the small black spacer tubes that you can see in the second pic This one was a spare that came from a UK race car called Bugster . I havnt used it yet so can't really say how good it may be. (http://im1.shutterfly.com/media/47b9df23b3127ccec651cc2ee6dd00000040O08QcNmjlq2Zg9vPh4/cC/f%3D0/ps%3D50/r%3D0/rx%3D550/ry%3D400/) Regds |
