Title: Pull type clutch on T1/G50 Post by: Andy Sykes on November 11, 2010, 12:08:59 pm Is it possible to use a pull type clutch on a T1, im fitting a G50 box over the winter and I am looking at my options for flywheels and clutches so it would make sense if a could use a 911 plate and disc. I mainly concerned about the crank thrust bearing load using a pull type any body got any ideas

But it's not that hard to work out.

cheers andy Title: Re: Pull type clutch on T1/G50 Post by: Udo on November 19, 2010, 06:30:58 am What clutch do you have ? On a 228 porsche clutch you have to weld the Type1 flywheel on outside diameter

It is just a flat flywheel...what the heck, I have some pictures. It is made out of SIS 2541 which is pretty much a Swedish 300M. Not for sale but maybe the pictures help?

cheers andy Title: Re: Pull type clutch on T1/G50 Post by: Udo on November 19, 2010, 21:00:10 pm Yes , this is how it looks like when you have a porsche clutch. I have one of this for sale but it is for a type 4 engine. I also have a welded type1 that needs to be modified
A 228 mm is very big , may be someone knows a smaller one ? Udo Title: Re: Pull type clutch on T1/G50 Post by: Airspeed on November 19, 2010, 21:22:05 pm What clutch do you have ? On a 228 porsche clutch you have to weld the Type1 flywheel on outside diameter Not neccesarily. I just remade a OEM type 1 flywheel for 228mm by just machining, no welding done. It now fits my G50 so the 1200 motor can get in ;DUdo Title: Re: Pull type clutch on T1/G50 Post by: Andy Sykes on November 19, 2010, 22:40:54 pm we could have a breakthrough KEP are getting me a price on a custom flywheel :)
Title: Re: Pull type clutch on T1/G50 Post by: Andy Sykes on November 23, 2010, 23:27:51 pm good news back from KEP
Ok that number is for a late G50 1990-1994 open diff. You should have a bushing in your starter pocket to support the end of the starter. Please verify this. The flywheel for that is a lot more expensive (i it would be ::)) and the ring gear is bolted to the flywheel. The cost for that flywheel is 542.00 USD the cost for the clutch kit is 902.00 USD Shipping around 155.00 USD and then the import charges :'( so looks like its now possible thanks a few emails ;D just got to sell my right arm now cheers andy Title: Re: Pull type clutch on T1/G50 Post by: Udo on November 24, 2010, 12:57:01 pm Why don't you use a porsche clutch that has the ring gear on the pressure plate ?

Udo hi is that not the same thing ? or am i missing something cheers andy Title: Re: Pull type clutch on T1/G50 Post by: Udo on November 25, 2010, 12:36:19 pm May be it is the same . The price for a porsche clutch is nearly the same if you have a steel clutch (Aluminium 1200 euros ) .
I was suprised about the bolt on gear ring only .. Udo |
