Clutch Pivot Ball - Wtf Does It Do?

[stomper]

Ok, So i am finally going to get my OS Giken twin plate (TS2CD) put in to my car. The existing clutch slips like a bitch, and when it gets some work in traffic, i get a grating feeling in the pedal.

When i get the clutch put in, should i look at upgrading the standard pivot ball to the nismo one, along with the pedal bracket.

What does the pivot ball do, i assume it interacts with the selector fork???

Also assume that he nismo pedal bracket is stronger?

Help and explanations greatly appreciated.

Thanks

Mike

to dis engage your clutch the thrust bearing needs to be pushed towards the front of the car .

your slave cylinder faces towards the rear

the fork acts like a see saw ontop of the pivot to connect the 2

Anyone have a view on whether it is worth $70 for a Nismo one or is the stock just fine?

they do break sometimes...but I've been using a standard one for years of abuse on the race car without trouble.

Cheers for that - how about the pedal bracket?

just stitch weld the pedal, the one out of my 32 snapped like a carrot.

some people put a spacer under the piviot ball, lengthen the fork end and put spacers at the clutch slave to make it softer.

lots of things to think about

yeah +1 clutch pedal bracket is a common failure

I've snapped a pivot, not exactly fun trying to rev-match a synchro box to change gears for 10km. Crash box on the other hand is fine

For the peace of mind (especially with a heavy clutch), I'd put the Nismo pivot in while you have the box out.

Oh and I've had my Nismo pedal bracket sitting there for YEARS in anticipation of my breaking lol

Yeah, I've snapped 2 pivots (both R32 gearbox). Both times it also damaged the slave. The first time I drove home with no clutch, the second time the fork was wedged in the clutch jamming it half on, half off so when I tried to start it up & drive home it killed my clutch within seconds (was probably close anyway...) Felt like an auto with a high-stall...

Also snapped pedal box once, just got a new standard one & seam-welded it. In my opinion stronger & cheaper than Nismo.

As mentioned, for the sake of $70 get one & avoid any potential headaches
