Fly wheel resurfacing - V6

Hi all,

I have been working on a 1969 Jeep CJ5 with the Buick V-6 225 for about 2 years now. I'm currently about to do a clutch job and I noticed that the fly wheel has some minor scarring, much like a brake rotor when small grains get between the pad and rotor surface. Since I have the back of the engine exposed, would it be a good idea to resurface it? Has anyone had any experience getting this done before? I do have the FSM but its currently in a different state than I am in...Any help or comment would be appreciated!

 

you are supposed to resurface flywheel every time you get a new clutch. I would, its kinda like insurance. that way the clutch is guaranteed to work correctly.

it cost me about $40 to get mine done, has a nice grease free surface to put the clutch one.

Note: some might say you might be okay, but like I said kinda like a cheap insurance.

 

To me it's worth the relatively minor cost to resurface. The new disc will appreciate it. What does the pressure plate look like?

 

Well the old pressure plate looks like a badly torn up rotor, but the clutch kit I've got has a new pressure plate and the works...Also for anyones reference TA performance makes OEM replacement flywheel/ pressure plate bolts.

 

Do resurface the flywheel. It is a minor cost and effort at this point... and a PITA to do later.

Thanks for the info on TA Performance.

 

Standard procedure and cheap insurance to resurface the flywheel when replacing the clutch disc.

 

most local automotive/truck machine shops will do it for about $45 , while your at it change pilot bushing

 

Ask upfront what the cost is. If it still has the outer rim on it sometimes they want to charge double because they have to change the cutting stone. I have had one place charge me $85 to turn it. I have not been back there either.

 

Oddly the local NAPA can grind it down for about 30 bucks! Has anyone ever had a fly wheel bolt head snap? If so how hard is that to remedy...

 

How exactly is a flywheel resurfaced? I'm envisioning a surface grinder with a magnetic turntable (worked in commercial machine shops that had them), but I can't imagine an automotive machine shop having one. Also can't see it being done on a lathe. But I've never had one done.

 

Most use a wet stone method that cuts across the flywheel..........and most I've seen clamp the flywheel down to a horizontal rotary table.........the table turns maybe 40-50 rpm's while the stone several thousand. The machines take up a space about 36" square.

 

(Scoot forward to 52 seconds to see the flywheel work)
