My flywheel looks like a golfball with many dents on it from the previous owner. I was hoping to resurface it, is that possible without having to rebalance? It is a N318 flywheel, any help is appreciated. Thank you.

 

Its a stock flywheel. Just take it to any trans shop, have them look at it and they'll let you know right then. My guess is, golf ball sized dents. Buy a new flywheel.

 

There are alot of hammer dents on the flywheel itself. I was hoping to get it smooth and not have to spend so much on a flywheel and counterweight.

 

as long as the scoring or surface isnt too badly messed up any trans or machine shop can resurface it.

 

I had a shop resurface my Turbo II flywheel, it cost like $50. Buying a used one could possibly cost you slightly less, but it'll be unlikely that it's been resurfaced recently.

 

So, I will not have any vibration or balancing issues with the stock flywheel resurfaced? No rebalancing is needed? Thanks

 

The counterweight is molded into the flywheel.

You will not have any balancing issues if you get it resurfaced, unless they take off more material on one side of the surface then the other. In which case that shop sucks.

 

Wow, $50?! It took me $15 to resurface mine.

 

I think that's what it cost. It's possible I had him do a couple other things at the same time. I was hurrying to get my motor built, it was my only car at the time thanks to my ******** wife bitching about me having a third cheap car around (we're divorced, good riddance). Regardless it can be done if it's not already destroyed.

 

Any of the stock flywheels can be resurfaced, multiple times if necessary. Any time I buy a used flywheel I always have it resurfaced. Make sure the shop knows (in the case of an NA flywheel) to also take down the pressure plate mounting pads the same amount they took down the main surface!

Cost is usually between $50 and $80. Some shops will charge a premium because the Mazda flywheel is odd compared to the piston flywheels they deal with and they have to use different jigging. $15 seems really low...must have been a shop seriously hurting for money.

Before reinstalling a resurfaced flywheel, hit it with a Scotch Bright pad to rough up the surface and make sure it is totally clean with residue free brake cleaner. Oh, and replace the engine rear main seal and the transmission input seal while it is out. And the pilot bearing if you have the puller...

 

I am missing one of the studs that mount on the flywheel. Those have to be ground down as well? I am ready to take it down to a good machine shop in the morning.Thanks guys!
