2G Opinions on my clutch setup condition for reuse. 20g AutoCross Car (pics)

[GofaST4life]

Whats up everyone.

If you follow my build thread, you'll know that my GSX, Wendy, suffered a pretty epic engine failure. Ive decided to source a block/used motor and get her back to running. In an effort to keep everything as budget as possible, I was hoping to reuse my clutch setup.

ANYWAY.....So I pulled out her heart and started to dissasemble. The Flywheel, clutch, and Pressure Plate look like they have taken a beating! I WILL BE shimming the pivot fork this time around.

This setup saw, 100+ AutoCross Launches, 4 drag passes at the SO, but was holding 32psi on E85 until the motor went. Never slipped with my 20g Setup on E85.

Can anyone give me some insight on whats usable and whats not? The pictures dont show all the pretty colors, ""

that friction material is hard on metal surfaces. so it looks normal for how you are using it. how thick is disc? they are around .335-.340 new. and start slipping around .260-270. that friction material is also not fussy about a break in period or condition of metal. so if your disc is thin you can drop in another without resurfacing pp or fly. dont it a few times here.

If it's a southbend you can get the disc relined for $100. I would atleast stick the flywheel and pp in a medi blaster and freshin up the surfaces.

Ill have to measure the thickness and report back.

Its a Comp. Clutch setup. Ill look into having them blasted.

The flywheel would need a resurface if you are going to use a new disk; that looks like a Competition Clutch 5048-2600 stage #3 clutch.

The Comp disk shown is 0.315" when new.

If you weren't having problems with it, confirm thickness, and put it in if you want to get more life out of it. If you resurface the flywheel and don't replace the disk or the pressure plate you will just end up with an uneven friction surface of the disk trying to hold against a flat friction surface which will only result in lower torque capacity and a waste of money.

When you are ready to replace, either resurface the flywheel or pick up a new flywheel when you get a new clutch.

The material isn't picky about gripping to used surfaces straight out of the box, but uneven pressure plate and flywheel surfaces are a recipe for a dragging clutch. Perfectly flat surfaces give the clutch a much better disengagement.

So, if I understand what your saying, I have 2 options...

1. Measure the thickness, if its in spec, I can re-install and use it for another season or two. I will be shimming the pivot ball this time, so I should have a little more "throw".

2. Measure the thickness, if its not in spec, resurface the Flywheel and buy a new Clutch/PP setup.

Do yourself a favor and RESURFACE. IMO that clutch disk is TOAST. New disk and properly resurfaced flywheel and PP and you should be good to go. Note that you need the flywheel resurfaced to step height and not many shops even know what that means. Also, not sure what fork you're using but if it's the stock one, with that much abuse, you can be sure it's out of shape. CC makes a forged one that is much stronger.

I already have a CC Fork. So thats all good.

I was almost thinking the same thing. maybe resurface both, get a new clutch disc and call it a day. The PP is in good shape, and it would save me $$
