RV8 - flywheel install - ARP bolts

[adamnreeves]

Noooooo. I thought I'd be stopped by a missing bolt this weekend, almost right. It seems that the gap between the bolt head and the centre spigot housing in the crank is too small for my socket to fit over for a complete turn of the bolt.

I have tried all my socket sets I have and they all exhibit the same clearance issue.

I have also tried my crowfeet spanners but as these bolts heads are 12 point they do not fit. Same issue when using a spark plug socket.

Anyone else had this issue?

yes pretty much everyone has, I have a socket that I stuck in the lathe and turned down so it fits now. You could do the same by carefully grinding a socket to thin it down.

Thanks mate. Trusty angle ginder did the job. Flywheel on.

Same applies if you fit 1/2" head studs..

The damn socket wont fit anymore !!! handy that they are both 3/4"/19mm socket size.

Same socket now does flywheel bolts and big head studs

I didn't have any trouble with my ARP head studs, standard socket was fine.

But did you use standard 7/16" head studs, or larger 1/2" head studs

I bought the standard ARP studs. I think the socket I used was a 5/8" so probably the 7/16" ones.

I had to grind a socket down to get my flex plate on withy the ARP studs. Real Steel told me I would have to.

My supplier did not warn me
