R33 Pivot Ball And Slave Replacement

[drpheel]

A few weeks back I pulled the tranny out to inspect a strange feeling when presseing on the clutch pedal. i found the pivot ball snapped near the tranny casing but still attached to the clutch fork. i have replaced with a nismo unit as well as the clutch slave cylinder. Now that my system is bleaded and the tranny is back on I get clutch slippage at verry low rpm and with no boost at all. also when i bleed the clutch , after releasing the extra air from the slave pussing the fork the clutch pedal stays stuck to the floor and i have to pull it back with my foot. The clutch also engages verry high but has a good smooth feel.

Do you guys think that the clutch disc / pressure plate got un-even when the pilot ball went bad ?!

Any info or tips would be great!!

Thanks

Adjust the pushrod on the master cylinder. It has been adjusted over time to compensate for either a worn out clutch or the broken pivot ball

Thanks for the fast reply! do you mean the push rod from the pedal to the master Cyl !? Will i need to re-bleed the system after ?

[The Dan]

Yes that's the one, and no rebleed is necessary

Thanks for the tips!

I will try to fix it in the morning

I also forgot there could be another issue and that is if you have installed the wrong pivot ball or it's too long. You will actually hold the bearing against the clutch which could engage it. Then no matter how much you adjust that pushrod it won't fix it. R32 and R33 pivot balls are different and possibly S1 R33 is different to S2 but I have never checked so you'll have to do your own research on that

the pivot ball was the same lenght / size as the old one, I compaired both pivot ball and slave cyl befor changing them so sure those are okay ! I will take a look at the master cyl ajustment when i get at the shop in the morning and keep you posted!

Thanks again

So i got the the garage this morning and I noticed that my ajustement to the master cyl was set back as far as it would go, So then I started to think that if the clutch is still slipping then the slave is not pulling back enought. Some how the clutch slave Cyl push rod was a bit to long !? got one from a HCR32 in the nismo ECR33 one and now its gripping hard and the clutch is not engaging near the dash any more

Hope this can help someone that is having the same probleme
