I was wondering who all on here is using the SPL or NISMO clutch fork pivot ball? What mods? HP? etc etc. Did some research and found that it is a recommended replacement over the factory if you have a high performance clutch and pressure plate. Long story short........ i found this out the hard way and i need to replace it and i was just wondeing who all on here is using and how long they had it in and HP/torque numbers will be good too. When i first did my swap i never seen that this was recommended so this is all new to me. Any feedback will be appreceiated.

it has little/nothing to do with your power, mostly your clutch pressure plate and what you do with the car

personally i never had a problem with the stock one and had 2000 track miles on my rb25 when i yanked it. the nismo one should be fine. dont worry.

I recommend anyone who pulls their trans from the motor to change it. It'll be the best $$ you might never k ow that you've spent.

Mine broke with like 2 miles on the motor. Literally. ..

O ok so it's almost like the luck of draw then huh? Is there anything else I should look for that would cause this? I'm so worried because this will be my 3rd time yanking my trans out because of this issue, and I want to be sure there is nothing else that I mite be missing. I don't think I beat the car up or anything, I haven't even launched it. I mean I do get a little heavy footed sometime but ey......... Have to enjoy the car sum after the hard work and dedication

and man Sil240 that suxs, 2 miles? I woulda been pretty salty about that. How long ago did this happen? And how has the nismo/spl held up for u?

Yeah a shyt a brick like crazy when that happened.

The car was actually getting the Downpipe built. And they stepped on the clutch and snapped it.

Def pick up that Strengthened pivot ball from Raw Brokerage before you put that trans back in.

Also if I understood your post right, this will be your 3rd time changing this.Have you been replacing the broken ones with used old stock ones?

If you did go stab yourself in the eye with a fork and see Hot tub time machine. (funny as hell!!!)

But if you've broken 2 strengthened pivots, then something is wrong. Make sure you screw it in all the way and torque it to spec.

Do you have some crazy custom Pressure Plate?

Beating on your car doesn't matter to the pivot. The Pressure plate force does though.If you have a crazy clamp load, that would put stress on the fork and the pivot.

But.... the pivot should be able to take it.

Also make sure you drop a dab of lithium grease on the ball and the fork.

Yeah it's my 3rd tIme pulling the trans, 1st time I thought it was the clutch so I replaced the clutch and flywheel surface, 2nd time I replaced the pivot ball, clutch fork, throw out bearing, and retaing clips with new Nissan overnite parts from japan j/k and now I'm puttin in the strenghtend pivot ball. And yeah I have a 6puck stage 3 clutch. I'm jus surprised I didn't catch anybody having problems with these until I started searching. Even when I searched for clutch noises when I pulled the trans down the first time I didn't see any mentioned of it. And I did grease the fork and pivot ball when I went in the second time.

solution on the top, problem on the bottom. Just figure i would post a pic of the side by side comparison. The one i used was the pivot ball from SPL and as you can see how much more beefier then the stock one on the bottom. I recommend this to everybody doing a rb swap period, just save the headache of having to pull the trans back out to replace this $40 2nd day air shipped part. Thanks for the input guys i put it in this weekend and so far so good.

hmm i have a question maybe pertaining to this....

when i push down on my clutch pedal i have about 2 inches of slop before the pedal actually starts pusing in the clutch... any idea what may be causing this? does anyone think if replacing this will fix the issue? i also didnt replace the slave cylinder that came with the swap if that helps. but i bled the system and put brand new fluid in, and there is NO air in the system whatsoever.

i wasnt sure if you could do that or not. i thought you could. but never tried it. ill look it up. i also have a stage 3 clutch. and when i say slop its not loose or anything, it has a little pressure but doesnt kick in until about 2 inches into pushing the pedal.

On the back side of the pedal is a pin and a cotter pin holding it in.That pin goes through a shaft going into the firewall.Loosen the nut, then turn the shaft to adjust the pedal height.

Figure out which way, cause I don't remember.

It could also be the master or slave cylinder going bad and leaking, or also the clutch system needs bled.

I find it weird Ive never really heard of much of a problem until the last couple of years. But I had a spec stage 3 on my ka and never had an issue. And I clutch kicked the S*** out of that setup no problem.

But as far as i know its impossible to pull a mckinny mount swapped rb trans (wow thats a mouth full....) so I have a nismo piviot in my rb setup.

Good luck now that you've figured out the issue.

Well......... The noise is back!!!!!!!!!!! Now before the suggestions roll in, before I put the first pivot ball in everything in the whole clutch system was replaced, and I mean everything. I jus don't know what the deal is....... I'm out of ideas

Throw out bearing is new, pilot bearing was in decent shape. The noise happens intermittenly, jus got done driving it and it makes the most noise drifting down a hill backwards and you push the clutch in and put it in a gear, thats when its really evident. Then again thats when it really would be because the transfer of motion drifting down the hill then pushing the clutch, putting it in a foward gear. I dont slam it in gear when i did, jus regularly put it in gear. Ive replaced the clutch master, clutch slave, clutch fork, throw out bearing, pivot ball, pivot ball retaining ring that holds the clutch fork on the pivot ball, slave cylinder rubber hydraulic hose, the other retaing clip that holds the fork on wear the throw out bearing is mounted to. And the only reason why i threw parts at it cause my parents dont like the car sitting in the drive way. Only thing left is the F'in trans. This car is pissing me off.
