Bumping for 2 reasons.

1: It's been a few years now since this thread, and keeping in mind the content of the thread re: explosions etc, has anyone had exploding patrol clutch yet?

2: What model Patrol does this clutch belong to? What year range? I don't want to turn this into another 5 pages which lack info, so anyone who's 100%, fill me in.

A bit of over reaction here I think. Yeah I fitted one of these years ago and posted up some info on it at the time.

Basically the only difference is the clutch plate itself, the pressure plate and throwout bearing have the same part numbers as the Skyline clutch.

When you compare the two driven plates, the only difference is the size of the springs in the sprung center, and they do not effect the clamping force or

load rating..only the engagement characteristics. Clutch plate material is organic like 95% of stock clutches, and doesn't have any magicial properties or hidden pitfalls,

and certainly doesn't know how many rpm's its doing.

As for results, it lasted 180,000k's and wasn't treated the best at times. The stock one gives around 130,000 if your lucky.

Driving with it was pretty much the same as stock, maybe slightly quicker to engage, pedal height & feel about the same,..hope this helps.

Basically it's just the VL 3lt rb30 commo clutch offered in two forms..std & hd.

Going to add some useful information re: Exedy part numbers. - Then see if someone can shed some more light on this.

In regards to FITMENT, all of these clutches should be interchangable:

NSK-7056 - Used in R31 RB20's and R33 GTS-T's

NSK-6797 - Used in R31 RB30E's and VL commodores, various Navara's and a Cabstar.

NSK-7121 - Used in R32 GTR's (earlier models with push type clutch)

NSK-6151 - Used in MQ L28 Patrols, and the GQ Y60 RB30 Patrol

Now each clutch is available in it's different forms below:

(Using NSK-6797 as an example)

OEM Replacement:

NSK-6797

Sports Tuff (Pink) Series:

NSK-6797HD - Heavy Duty

NSK-6797HDB - Heavy Duty Button

NSK-6797HDCB - Heavy Duty Cushion Button

Racing Clutch:

NSK-6797SO - Sports Organic

NSK-6797SC - Sports Ceramic

NSK-6797RC - Race Ceramic

Safari Tuff:

NSK-6797ST - Very close to Sports Organic. Read below.

Now with all the variations of clutch set in this way you can see they come under certain groups. This is how Exedy sets them out on the website. Now if you read the description on the HD clutches, it doesn't mention anything about anti-burst pressure plates, etc. It pretty much says the plate comes with more clamp force and that's all.

Now read up on the Racing Clutch series, they start here with spheroidal graphite pressure plate castings, and additional drive straps to prevent bursting at high RPM. So until you reach this series, all the talk about exploding clutches should be a moot point. Race series comes with usually at least 3 choices. The first being organic friction plate with the same design as OEM or HD so you'll get great driveablility out of them.

Keeping all this in mind, now go read up on the Safari Tuff cluches. They boast the same increased clamping force as the Racing Series, they also have the same anti burst pressure plate design as the race series, with an organic clutch plate, again like the Sports Organic in the Racing Series.

I have found Safari Tuff clutches that will fit for $450odd. Besides a weaker spring setting (that doesn't mean weaker springs like they will break) I don't see really any difference between them. Now if Patrol clamp loads are high than Skylines OEM (someone mentioned this, but is it true?), you can expect the Safari Tuff would outperform every other Organic clutch option that's availalable to fit. The only thing you wouldn't want to do is huge AWD launches because of the weaker spring. But then when you think about 2000-3000kg 4WD's doing hill starts on rocky surfaces, these clutches aren't princesses anyways.

It's been years now, even the cheaper HD Patrol (NSK-6151HD I assume) clutches aren't exploding, even without their anti burst casing.

So whadda ya's think? The price of a Sports Organic Race Clutch is well over double the price, all for some spring settings? I think when you put the word Skyline on something the price doubles.

[quote name=ClutchBurndout-:(' timestamp='1301282150' post='5733839]

so S1 r33 gtst cant use them?

You should be able to get anything in the list above as well. Give or take clamp loads, which Exedy doesn't seem to provide for all of them so it's hard to compare that.

Edit: Has anyone used a Safari Tuff clutch in a Skyline? :D

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
