Hi,
I'm trying to open a dead Subaru IHI RHF4 vf14, ball bearing.
The intake side nut on the rotor is of strange size. It's between 7 and 8 DIN, I also tried SAE wrenges and it also falls between two sizes.
Is there a special tool for these IHI ?
On the exhaust side it's a 11 DIN bolt.
Thanks

OK, I managed to open it. It's actually a 7mm wrench, I don't know why I was not able to use it yesterday.

excitment ?

extreme cold in the workshop ?

using an 8 mm spanner and believing it's a 7mm one ?

A combination of the above ?

Rusty by nature
