with thier setups.
In a response to the question I posed to RAM about using the stock FW with the 402 PP and either 980 or 6130 disk.

Shawn,
Perhaps I left something out here. The reason the drive pins/bolts are so important is to keep the pressure plate properly centered on the flywheel (in balance), and to allow the clutch to drive against the two. If you use the stock bolts, the plate is driving against the bolt threads instead of the shoulder of the bolt. That's why the counterbore is necessary on the fw mounting holes to use the shouldered pressure plate bolts. The factory holes have the threads right up to the mounting surface.

The mods need to be made to the flywheel, not the plate mounting holes.

The 980 will work fine with the stock flywheel.

I realize this might seem like its not really necessary, and I know several people on the boards have drilled out the pp holes to make it work, and it will. I'm just trying to get you to do it the RIGHT way! <img src="gr_stretch.gif" border="0">

BTW, this would be an excellent topic to post.

Thanks,
Mike


Let me know what the standard response is from the hardcore users like Harlan etc.
I would still like to use the stocker if I can get away with a resurface and expect the system to hold up. <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" /> the leaders of this setup <img src="gr_grin.gif" border="0">

 

Riiiiiiiiiiiiiiiiiiiiiiiiight.... <img src="images/icons/rolleyes.gif" border="0">

I know 3 or 4 guys running stock flywheels and 402/6130 setups, no problems. Nice sales pitch for selling their 400 dollar flywheel though...

I went with what Harlan said..stocker is fine. If it holds up to his monster...my Tonka toy is a breeze

<img src="graemlins/gr_bs.gif" border="0" alt="[bullshit]" /> Centered on the Flywheel? Isn't that why the 6 bolt holes are precisely located on the PP?

I heard it's not uncommon to have a minor vibration at certain speeds with a HP clutch. As long as it is just a transient it s not a big deal.

 

come on guys all he is saying is you should counterbore the bolt holes. they arent tring to sell you the flywheel!! I called RAM when i ordered mine they said NO i dont NEED their flywheel just need to modify mine it wasnt hard to do and they explined how to do it. I RESPECT that in a company to take time to explin something to save me money on their product!! the did't have to do that! <img src="graemlins/gr_hail.gif" border="0" alt="[hail]" />

 

Thanks Tim. That is true - I could care less about selling the flywheel. What I DO care abut is someone using our clutch and having a problem. Balance is the issue here, along with the fact that the pressure plate is designed to drive off a shouldered clutch bolt. If the clutch repeatedly beats against the threads of the stock bolt it COULD ( I emphasize could) cause a problem. BTW, the flywheel LISTS for $275.

Anyone know how much extra an aluminum flywheel is with a RAM set-up?
