BAFS...Bug@5speed Wally TOB sleeve (or guidance tube as Martin calls it) Very nice machine work too!

Sandeep,
Did you already try to slip in a 915 disk between that 228mm type 4 flywheel and your 228mm type 4 pressure plate?

I have tried a new (!) LUK 228mm pp I bought for the occasion and also wanted to use Martins guidance tube, but I had the first batch that did'n't fit in the 915... After I had it machined some more, it probably will fit now.

The new LUK pp and the 915 disk would not fit . After consulting with Martin how this is possible, he got back to me explaining there are probably two versions of pp's and only one fits...
Recently I got another (used) 228mm PP from Fichtel & Sachs and that did not fit immediately either, but due to the different construction of these, with some clearencing of the pp and a bit of the disk, the 915 disk now spins freely in the 228mm F&S pp!

So if you want to go this route, I suggest to at least go with a F&S pp or get the Alfa 164 disk Tom mentioned earlier

Any reports on annular trow-out bearings that will work on a 915 box and are small enough to fit between there and the 228mm PP, are greatly welcomed

Regards,
Walter

Wally,

Thanks for the information. I have not tried the 915 clutch yet because I have not ordered it. I am looking at a custom disc, either from kennedy (6 puc solid) or from a local porsche tuning shop. I need to use my kennedy stage 2 228mm PP and will take the fw / PP to the porsche shop and see what we can come up with. If no solution can be found, I may have to try the F&S as suggested.

I still have not ordered the hydraulic clutch kit either. Are you happy with your setup -> clutch pedal acctuation ? I can sort out the slave cylinder.

At the moment, yes, very! Even tho the stock 915 pp is very heavy, when you have exactly the right pivot point length of the clutch arm where you hook the slave onto, your good.
Since the 915 needs a longer throw I heard, I originally used a smaller pivot length and pedal pressure was too high for my taste. After I lengthenend the pivot arm, I can still clutch the disk free and all is good
That took some time and wrenching tho... and I should really let it be for now

[Sandeep]

Cool !

Are you using the SACO kit or the Aircooled.net kit ? Are they the same ?

I've almost got the 915 box mounted in the chassis, now need to sort out the clutch.

Thanks

Its the SACO kit, but the acn-one is probably the same. I bought mine from Alex from VW-ISP-West (or something like that name), who mostly do type 3 parts. The sell the updated, upgraded set throuh ebay as well IIRC. The new set has at least better tubing for the hydraulical line front to back.
Just do a search on SACO here on GL, as Shad Laws did the saco set as well with his 923 in his late type 3 fasty back then and had a few good things to say about it (figures huh )

hey guys - what was the outcome of this in the end?

ive got a 228 flywheel/pp but not a friction plate yet what did you end up running? also any chance of a pic of your slave cylinder/clutch arm set up??

thanks for your help
