Roberts 89 GT/U build 3400/3500 WOT-Parts

That's just down right scary looking O.o I can't imagine how it would have smelled going down the track. Wait, I've smelled clutch burn before, never mind, lol.

That's glazing on the pressure plate... it looks white in the camera photo but it's not quite that color in person. Spec Stage 2+ is made up of carbon semi-metallic on one side and Kevlar on the other, The semi Metallic side faces the pressure plate so I'm sure that's why it has a very odd look to it. Similar to a cooked rotor.

It could have some grease contamination from the input shaft, but I'm not positive on that... all I know is he had a bad run in with shift cables and during that incident he thinks this damage is what happened.

This is another Bnet user who had a spec Stage 2 clutch and it was slipping from having slow releasing hydraulics when he was trying to shift quick at the strip... I think that's a stock GM flywheel but I could be wrong.

Spec said mine looked normal, other than the glazing on the disc (from when it was slipping at the track).

Did the pressure plate side get some sort of contamination in there or is that glazing? I didn't think glazing would be white. It also looks like that chinese flywheel couldn't take the heat too well.

As far as the razor blade use goes, I use the normal utility knife style since I have them on hand. I also hold them with my bare fingers. If I catch something enough for the blade to hurt my finger (and I don't mean cutting my finger with the back side), then I'm pressing too hard, or there's a burr or something there that I need to take care of. I hardly press down on aluminum, though, since I take great care not to gouge anything, even iron.

Cool, Thanks Ben.

And don't know if those are cracks never noticed it till you just said that they may not be since they are not visible on the other side, but yeah that flywheel can be reused, but he sent me up a fresh cut OEM GM one rather than having this Chinese one surfaced and re-used.

The Napa I went to also only had the yellow bristle disc, but I think that should be fine, I don't have any aluminum parts to do.

I had a set of rings here for the pistons I have had in stock forever now, so those went out today. Funny how things work out sometimes.

[bob442]

is that 2 cracks on the disk hub?

and that flywheel should be re-usable with a grind

[3400-95-Modified]

If all goes well and the ground isn't white after I build it I'll have a week of tuning to do on it so yeah there will be vids

All these part changes are pushing it back though so I'm gonna have to pick up the pace once I get everything.

I use razors often as well. I learned to put a magnet to the back side, aids holding the small blade and prevents the blade falling into places we don't want it too. Imagine, a loose blade....nightmare. Or even worse, a small corner piece chipped off and lands between the piston and cylinder wall.

I need to get some of those pads, never used them before.

Robert, we gonna get a video treat when shes all done?

[3400-95-Modified]

Never use steel wool or the scotchbrite pads on mating surfaces (aluminum). If you want something machine shops use, get the 3M bristle disc setup. White and yellow are milder than the green ones.

Picking up the white and yellow Bristle discs today... They do work very nice. I always just used a razor blade to clean the surface and never had any leaks, but since this isn't my motor I'll go the extra mile and use these.

My motor after 2 years of abuse... Never put any silicone on any of the gaskets, Just around the coolant ports on the timing cover.

[3400-95-Modified]

And to clarify the tensioner question what I mean is the center dampener the one for the 2000+ narrow chain is just a bit wider and doesn't fit the double roller chain well, the one for the 99 and older 3100's with the wider chain fits in there perfect, so I'll be using that.

Forgot to post what happened to his spec stage 2+ clutch.

Flywheel








Pressure plate












Disc

This appears even less than a six puck... That at least has 6 little pads... look at what a Clutchmaster Stage 3 looks like.

The light tan is the clutch material, NOT the dark brown.



I think I'd be happy with the FX200 for my Legacy


But $625 is insane... I can get that price from Fredbeansparts.com... Clutchmasters wants $735 direct.

"I'm just simply amazed at how little clutch material will hold power" - I thought the same thing when I received my Spec 3 Clutch. 6 Puck design good up to 500 hp. Amazing, 12 small little areas where all the power is transfered through.

[3400-95-Modified]

Been a little busy lately, but Ben said he's going to try to get the rings drop shipped to me from Total Seal, crank scraper is on the way and I'm going to get some other stuff done on the car while the motor is waiting for parts, like spray a little paint in the engine bay and such. I also hope to get the heater core pipes and fuel lines soon from a Bnet user.

Robert the clutch did show up last week I forgot to tell you that. I was about to return it till I saw the tag stating it had been bolted down for testing purposes since I could see where washers had removed paint, I was like WTF its used? LOL. It looks good and I'm just simply amazed at how little clutch material will hold power...
