I used 6 point and got it off with that impact wrench.
Leading evidence: 'Use 6 point and got it off' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace easily' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
You might end up damaging the crankshaft seal but I think that can be replaced easily?

Suggestion · Original poster
I'm trying to avoid using too much force (hitting that wrench withsledgehammer was causing some sweating...) because I don't know how that force is affecting internal parts (twist crank for example)

Not yet - so if I use torch there's a risk of damaging that seal?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Ok, any safe ideas how to remove that crankshaft bolt. That flywheel plate is secured with flywheel locking tool.
Tried with stubby impact wrench (Milwaukee M12) - no go.
Put 24mm wrench there and knock that with a small sledgehammer - no go.
Tried carefully with 3ft breaker bar - no go.

Put the locking pin in the crank pulley also.
You said you used an impact driver? Do you mean some 1/4" rinky dink thing or an impact wrench. Id use a big boy half inch impact and it should come right off
Have you tried a gas torch? If someone added red threadlock that might explain it, heat will soften the loctite. You might end up damaging the crankshaft seal but I think that can be replaced easily?
I had it there initially but removed as there's a risk of cracking that case ?
Ah, meant impact wrench - language issue
Milwaukee stubby impact wrench M12 1/2"
Not yet - so if I use torch there's a risk of damaging that seal?
Get a 1/2" drive impact gun and a 1/2" drive twelve (12) point impact socket. Lock the crankshaft pulley, then the flywheel. I would not use any heat because of heat expansion of the bolt and to protect the seal. My two cents...
I have this one
Milwaukee
M12
FIWF12-422X so I would assume that this would/should be enough - that 12 point socket is a good idea if I can find it relatively easily.
