New clutch already worn out? Safe to just reuse pressure plate and flywheel?
I bought a brand new ACT 6 puck clutch from FRSport and it's already hitting the metal sleeves on the clutch disc! I didn't do any clutch kicks and put barely any miles on it. And yes, I'm a great driver and babied the car.
I saw on eBay they were selling just the disc for 160$~, would I be able to reuse the pressure plate considering the flywheel & pressure plate are practically brand new? There are very very minor hot spots, but I'll have it resurfaced and ask the machinest. Before I hear it, I KNOW it saves time to buy a new clutch setup, but I can't dish out an another additional 400$+ for a clutch. I'm thousands in the hole and I can barely drive the car. There are other priorities at the moment, in a perfect world I would just buy a new clutch kit. It also only took me 2 hours to pull my engine out. Additional notes: The clutch grabs very hard, and doesn't slip at all. The learning curve was very rough, but that's what I expect from a 6 puck sprung. I wouldn't have known the clutch was hitting the metal sleeves on the disc until I pulled the motor out to respray the engine bay. |

Before you go buying a new clutch, have you absolutely determined it is defective? If it is in fact 109% defective, why don't you warranty it.
Did you have a 'professional' install it? I know at least through most programs they require a proof of professional install and alignment.

Sounds like u might not have any/ enough clutch petal free play. If u have no free play just at idling/driving car clutch is riding whole time, will burn up disk in no time. I see it all them time when guys do 5 speed swaps and take all the slop out of the linkage

Anyone else ever notice that the more you spend on one of those traditional type single disc clutch,
the less material you seem to get? If torque is < 300~ I would just use a full face disc, like stock |

It was a proper install, I've installed a hundred of clutches. There's freeplay in my clutch pedal. The clutch is out of warranty, I bought it years ago and the car just sat. It never smelled like clutch either.

Dang between you being an expert driver and a master mechanic I woulda figured you either knew how to fix it or made enough money to buy a new clutch.

The friction material fused to the flywheel and probably the pressure plate.
The problem here is you should have felt this the first time you put it in gear after hiatus. The disc job is to grab the pp and flywheel, id say it did that job too well. I mean look at all the rust it was inevitable, whine and cry to frsport and they might send you a new one even though the fault is not theirs.

Regardless, I spoke with ACT directly on the phone and said it should be alright to just buy a new clutch disc since my pressure plate wasn't warped and the hot spots were very minor. He states that the 6 puck clutch wears down very quickly and it should not be meant for daily driving. As far as symptoms, there were no symptoms. I'm repainting my engine bay and I figured I would take a look. |

Unlikely considering there's a sticker that indicates the direction lol. That's what I'm assuming but he said with excessive stop and go driving will cause wear because the clutch is so stiff. It's totally fine though, I'm going to put the pressure plate on a lathe and use a dial indicator to see if it's warped. If it's all good, I'll just buy another friction disc. If worse comes to worse, I will just have to buy a whole new clutch or put the project on hold. The minute I keep buying more things for the car it becomes and endless spending spree.

Just whatever you do, make sure you get a disc and plate that's rated for your setup.

And before you come back and say "oh the car had a few thousand miles on it, that's what I meant by barely any miles", you said you babied the car. No one babies their 1990s nissan shitbox for thousands of miles, and if you did a stock clutch woulda done you fine for tens of thousands of miles. Provide some useful details next time like mileage, pictures, and power numbers instead of pointless ones like how you're a great driver and you pulled the motor in two hours. Speaking of pointless details, since you like to brag about your mechanical skills, driving ability, grammatical correctness and financial life, I own a house; you're more than welcome to bring your car by and I'll help you figure out your problem. Lastly, so I don't get an infraction for not offering a solution; you can throw another disc at it, but unless the disc was the problem in the first place you'll just burn through that in another (I assume) 500 miles. I suggest actually finding what's wrong with the car before throw more money at ACT. Whether it be install error, driver error, a faulty part or something else. If you leave everything the same you'll get the same result. Post some pictures and numbers so we have something to work with.

Did you pack the recess in the TOB sleeve with molybdenum sulfide grease as per FSM spec? Did you also apply said grease to the face of the TOB? and Input shaft?

I baby my "shitbox". Just because it's an old car and fu*kbois don't take care of it doesn't mean everyone is that way. I like driving a clean babied ride.

Paco needs to stfu lol what a loser. To the OP, are you sure no one else drove your car or "borrowed" it? I'm betting someone that doesn't know how to drive took it for a joyride.
Also +1 for babying your ride, especially considering how rare and desirable the 240sx has become. After all its not a Hyundai |

If it was installed properly and you know exactly what you are doing then why are you even posting?

They have a computer that we use to dial/control exactly when I want the trans to shift, and how hard I want it to shift based on TPS position and engine vacuum. It does this with consistency that cannot be matched by a manual transmission. It also has a clutch which simulates the 1:1 connection between engine and input shaft, exactly like a manual trasmission, so you cannot even tell the difference at the wheel speed (eliminates converter slippage) and yes some can do this under WOT with Nitrous/Boost.
Anyone that posts what you just posted "blah blah blah control" has never been in a vehicle with a fully built automatic behind a twin turbo V8 engine. |

I think you need to re-define your version of what is a "control system". |
