Balanced it myself. Yes i'm cocky :lol:
Placed it in an air bearing with the original shaft inside. These air bearings have almost no friction. When i was done it didn't move .
It should be a lot better than the old situation witch had a light vibration. When was finished i put it an an cnc machine and spinned it up to 4000rpm. It was oke but i got scared to do it till 7000. If such big clumb of material goes it's a chain reaction... it will fly through the workshop. And with in mind if whe damage machines for our hobby , whe have to pay it ourselves. Fair for sure!

I guess it is oke.

Yeah, I would much rather have it tear through floor and bounce around the cabin then damaging something in a workshop...;)

Mats has a point.. :wink:

However, i happen to know where Peter works and i can imagine the huge costs involved if something gets damaged in that workshop. It's not the typical local garage workshop he uses. :wink:

Did you lighten the flywheel as well? Did you replace the bearings in the snout of the flywheel housing ( i can probably get you those cheap :wink: )?

bearings i can get myselve over here but thanks for the offer!

Didn't lighten the flywheel at the end. My thoughts where if i lightend it, shockloads from the engine increase on the gearbox internals. And i'm already ballancing on the border i guess.

I work at a University in a kind of prototype centre. Lots of knowlege over here. If i blew up the machine, cost easily go up to 1.000 euros or more... and a bad reputation :lol:

Ah, oke nice. Probely a lot cheaper then our suplyer :lol: .
But i already had a look at the clutch bearings,they make no noise and run really smooth. Also put the joke in a vice and checked the play. Felt really firm an saw nothing.


This weekend i bought an other gearbox for refurbishing.There was a bad reverse in my own ( lot's of teeth wear). Synchro of first was bad and there was a lot of play in the bearings in the gears. It was realy in poor condition. Wonder why it still didn't blew up :mrgreen:

So gonna make the best of two.

We actually have a sales office in Cuijk but i work in our sales office in Oss. :wink:

Biesheuvel Techniek (geen autosport helaas.. :( ) heet de tent.

@75Evo;

But if you cab get me the articlecode from SKF i can inquire at SKF about what is possible. :wink:

On page 6 the discussion was around gearbox and prop modifications linked to a company that supplied these parts http://www.artracing.co.uk/parts-and-services/
I saw track car that was in for and underbody service etc which had this kit on . Its runs a 24v motor and get pretty much thrashed . Thought I would add it here to keep the thread discussion .
The interesting part on the prop which has three u/j , is the rubber filled dampening section of the prop which I believe or has been mentioned already comes off an Aston. I did try twisist by hand and you can feel the feedback from rubber .( fractionally ) Its the smaller tube thats rubber moulded into the larger tube .
See the pics which include the reinforced clutch housing .

Looks like a very nice solution but expensive.. Keep it in mind.

Does anyone has experience with welding on the clutchhouse. Can it be welded?
Maybe i can reïforce the original just to play safe. That's a small job compered to the cage construction and a littlebit stiffer becuase there's no play. I know aluminium gets soft when it is welded. But it's a self healing material. Afther a few month it's in the old state again. So after the winter over here :D

Kevin also uses a nice solution for reinforcing the housing... the steel cage that fixes the snout of the housing with the mountingpoints to the gearbox, like a steel spiderweb. 8)
