Ouch!!!!! The flywheel came off? Did the flywheel break or did the bolts shear off?

BTW, what flywheel did you use? Some of the type4 flywheels are cast, and if I am correct all the waterboxer ones are forged.

when i put the flyweel on the small o ring was between crank and flyweel so it was a bit out of balance. then it was the bolt to hold all the power and when i did the test run. but fuck it runs well and it is much torq..

I ran a 200mm converted for the J&G on my Pro-Turbo Type-IV. Make sure you use the forged model and that you use only quality hardware (arp studs) and you will have a bullet-proof set-up.

It was years since I even touched a type 4, but I am almost sure FAT makes a 200 mm forged flywheel. The stock forged ones are as rare as hens teeth...

The flywheel in Bang's engine is a KEP 200 mm type 4, the bolts are the BAS 12.9 grade precision bolts and dowell pins are hardend steel 8 mm pins. All bolts and pins are snaped . As Bang wrote a piece of the flywheel Oring was cut during assembling of the engine. This little piece of Oring was between the mating surfaces of the crank and flywheel . The bolts shows signs of that they have been loose before snaping. So no racing for Bang Racing at SCC this year /Rolf

Have you guys though about using the waterboxer 28mm flywheel. I understand they are all forged.

As asked previously did the bolts shear? Is the flywheel the only thing damaged or is the crank destroyed as well?

Hi I only use 914 flywheels for race engines , they are steel . And i match it with Gene Berg dowel pins and BAS special screws , never had problems . You can machine it for floater or 200 mm kennedy - black magic .

the crank have marks on the end bot all the thret and holes for the pins are okay. think it can be done agin. i drive with a bus gear so the 228mm flyweel will fit inthere. udo i will bring the crank and flyweel to scc then u can se if it can be done if you want. )

Yes the bolts did shear. I will post pictures of crank, flywheel and bolts/pin later. The crank is damage but i think it's repaiable since the damage of the pin holes and threads are only 1 mm deep. BTW who sells the J&G floater clutch ?? /Rolf

Also the BAS screws . You can give it to Peter Köhmann if you want , and he has an expert (surprise guest ) who can look at the crank . Udo

Echoing Rick Sadler on the quality hardware
I had all the cover/stand studs shear off at the May Bugorama. No damage really, but lost my first round match because of it.....which sucks!

Yes i can , but if you need a new one i would take a 914 and modify it to 200mm with kennedy or modify for floater . The easier way would be kennedy and black magic . Have fun at SCC .
