Hey guy/gals, I need some info. My clutch fork fell out of place and I reinstalled it and everytime I press on the clutch pedal the fork falls out, I reinstalld it with the clip that holds it in place but it falls out. Is there some other clip or spring that holds it in place and does the dust boot act as a support.Please help.

This image is for a KA but it's applicable to the CA18



Should be two springs? One holds the throw-out bearing deal to the fork. The other holds the clutch fork to the pivot on the bellhousing. It's likely that that spring is bad and giving you problems. Not holding it on there good enough? I dunno. I bought new ones when I got the new clutch. The dust boot sorta supports it too, in a way.

Also, if the pivot itself is worn down, the retainer spring might not "grip" it well.

Honestly, just buy a new dust boot + pivot + springs from http://www.courtesyparts.com. They're cheap. KA stuff should work. At least I think so, pretty sure that's what I'm running on mine. But it has been like a year since I messed with any clutch stuff, haha.

Other than a worn out retainer spring/pivot I can't think of any other reason the fork would be falling off. Maybe triple check everything and use the new stuff? Can't hurt.

The retainer spring on the throwout bearing thing is prob bad. You need to pull the trand and replace the springs/retainers, and I'd put the NISMO pivot bolt in there. I've broken the stock pivot bolt multiple times.

are you trying to put the trans back in after a clutch job or something?

if so, the fork is not supposed to pivot far, this said, if pivoted furthur past design allowance, it will pop off, i had this problem while putting my trans back in, be carefull and dont touch the fork once set.

Pivot ball might have snapped off, part #30537 in that diagram. Peek up in there and see.
