In the oem shop manual it is said that it is not recommended to resurface that flywheel and i was wonder what the logic behind that is...i just dropped the tranny and pulled the clutch (which has no meat left on it) and the fly wheel does have some heat spots in it. I and best friends with a owner of a machine shop that will resurface it and he doesnt know the reason why they say not to resurface it...all input is appreciated!

 

I have done a lot of them and have had no issues with doing it. Honda uses a two step flywheel so both surfaces need to be turned. To do this you must remove the dowel pins. I would like to think that they (Honda) are concerned that the resurface job may not be done correctly or safely and not adding that statement in the manual as a money making thing.

 

You should not resurface the flywheel. It is very hard. I know several racers that grind the back side of a Honda flywheel to lighten it. It is not conducive to grind the front surface. Just buy a new fly wheel and you will not have any problems.

 

I agree with the first post that it is a two step flywheel and you have to resurface both surfaces...and to do that you extract and the put back in teh dowel pins! I agree that it is just a money maker or a way to make a techs job easier to just throw a new one in...what makes the s2k flywheel differant then lets say a b series flywheel that gets resurfaced a ton? I think that if the fly wheel stays in the specs honda gives us in teh manual it should be fine.

 

It is made of a good quality steel but, my machine shop that dose the work has no problem with cutting it. Very little is removed, we are talking a few thousands that

 

yea im going to resurface it through my machine shop because i have alot of faith in them and they know exactly what they are doing! And where did all this contriversy come from with this lightning stuff? I did not mention anything about lightning anything....i just wanted the clutch mating surface to be cleaned up cuz i dont want a 600 doller clutch to have premature wear cuz i didnt clean it up!

 

I lent comment to it because it was addressed in a post. I would not feel good if I did not address a very unsafe idea.

 

I got mines resurfaced , removed 0.15mm which is bout 6thou of an inch which is the service limit according to the manual. I have no issues. The reason for this limit is for maximum wear on the clutch disk and pressure plate, I however did both surfaces as mentioned above, so it's within service limit as oem. With proper break in period you will have no issues, also did the same with my dc5 type R.

 

What makes it a 2 step compared to other flywheels?
