I am trying to find out how much labor/cost is involved in repairing a JUN chromoly flywheel that needs to be resurfaced and cleaned up around the bolt area. The cost of repair will determine if I will buy it or not.

Heres the link to original thread with pics of the flywheel.

Thanks in advance.

 

how much are you going to pay for it? you can probley get a used act or exedy or even a aluminum flywheel for pretty cheap

 

i'm a machinist and what exactly do you want to do to it just clean up the face and pass a tap in the threads to clean them up cause it would most likely just be an hour of work at my shop we charge 50$ which is cheap cause we're a small shop. so it would be nuder 100$ easily might only take like a halfhour.

 

You would have to make sure you maintain the .100" positive step that Honda flywheels require, which means machining both the friction surface and the mounting surface.

Which will happen as I couldn't see him not resurfacing the flywheel at the same time. Also - I don't think those surface gouges will end up causing much of an issue down the road if the mounting surface is just redecked.

Thats how I was asking the machine shop for their quotes.
1. Mag flywheel for cracks
2. Repair/surface center bolt holes
3. resurface the face to .100"
4. Balance to 10,000rpm

But I am having trouble finding a solid quote around the SF Bay Area. The ask to see the part before giving me even a general quote, which is understandable.

Anybody have any suggestions on other good machine shops I could ask in the Bay Area?

 

Not any that will give you a quote without seeing the part first. Just head down to a couple and show them the flywheel.

 

i understand, but they wont even give me a general ball park figure.

 

I work at a engine machine shop
I would charge $35 for resurface
$30-$50 to resurface the bolt side on a lathe

you wouldn"t need it rebalanced due to where your removing the material

You cant balance to a certain rpm shops just say that to make the process sound better. you can only balance to a tighter tolorence then the part was origanly balanced to, on a internally balanced engine like a honda

I send my balance work out to a shop that does only balancing. they would probley charge $50-60
