How deep is the nitride treatment?
On a stock crank how deep does it go? I'm trying to search but found no good links. This particular crank is the f23a5.

Re: How deep is the nitride treatment?
has anybody ever actually had a crank failure that was truely due to not retreating the crank after turning? not one that was turned and wasn't done right or was not installed correctly. talking hondas here.

Most experienced builders won't use a Honda crank again if it's been turned because the hardened surface has been removed (nitrided or not). That makes them more suceptable to failure, so it's cheap insurance to get a new one.

Re: How deep is the nitride treatment?
I've read nitriding can be as much as .020-.030" deep, it just depends on the nitriding process.
I know it's not a Honda, but I've had late model V8 cranks turned more than .010" and still made over 500whp. The crank in my personal vehicle is going .100" undersize and I'm shooting for 520whp on motor.

For a daily application it should be fine to turn and get the bearings to match. If its going to be a "race application" under extreme stress or load significantly more than every day driving...might not wanna risk it.

Re: How deep is the nitride treatment?
I dont believe any amount of cutting will remove the nitride treatment. That would mean any micropolished crank would fall into this category too. I have read nitride treatments will case harden the crank to a depth of .020" to .030".

Re: How deep is the nitride treatment?
^^ thats likely an oiling/clearance issue
nitriding as it is done to cranks is typically less than .010" deep, ie any turning will remove the hardening, polishing will not. That being said there are many cranks that aren't nitriding, these use a different form of case hardening. Nitriding is used more as a longevity thing. Honda cranks are good for like a million miles if you keep it oiled properly and maybe change the bearings once or twice

I'm using a crank that was used on a f22b1 on a f22a1 block with new everything it even has f20b pistons and an f20b head and it will be supercharged soon 7 psi it has not failed me yet. I didn't get it turned or anything like that but it was not worn it had 142,xxx miles on it and it revs to 8500 rpm. i will let you know the out come it practically an h22 it has 11.78:1 compression on a 4dr civic ej.

Re: How deep is the nitride treatment?
If proper clearances are kept, turning a crank should have no I'll effect. There shouldn't ever be a point at where the crank rides on the bearing to matter. Any time the crank come into contact with than bearing under load there is another problem all together.
