prs Posted January 28, 2005 Share Posted January 28, 2005 I've just had a new CRB from CC and they have changed the manufacturer. The old bearing had F-202994 made in Brazil and the new one has FRA174C Made in France. The new one doesn't fit the lever arm quite so securely as the old one but I'm sure it'll be ok. I've got a Caterham DS if this makes any difference. I was going to modify the pedal box and do the two spring setup to increase the preload as shown in LF, so my question is this is it still ok to do this with the new style bearing. I will contact CC but thought I would enquire to see if anybody else has done it. Phil S7SVN Link to comment Share on other sites More sharing options...
Jason Plato Posted January 28, 2005 Share Posted January 28, 2005 Hmmmmmm I slotted in a fresh CRB last week and it was a Brazilian ( I know it was Brazilian cos it has a little strip of hair on the side ) Link to comment Share on other sites More sharing options...
prs Posted January 28, 2005 Author Share Posted January 28, 2005 Dave CC told me they have been using this new type for about 3-4 months, when did you order yours. I assume the one you fitted had the metal clips with a lug that locates on the lever. The new one is all plastic at the back with plastic lugs as well Phil Link to comment Share on other sites More sharing options...
V7 SLR Posted January 28, 2005 Share Posted January 28, 2005 Myles has only very recently purchased a new one from CC which was Brazilian too. Certainly less than 3 months. I would have thought even a single spring will be enough as long as it exerts enough pressure to keep the bearing face touching the clutch pressure plate tangs.

prs Posted January 28, 2005 Author Share Posted January 28, 2005 Hmmmmmmm beginning to sound iffy this, me thinks I'll ring CC again and double check, was hoping to put said engine/box back in this weekend. Phil Link to comment Share on other sites More sharing options...

prs Posted January 31, 2005 Author Share Posted January 31, 2005 Spoke to CC tech dept on Friday about this, they apparently changed due to quality control issues. Phil Link to comment Share on other sites More sharing options...
frankyknuckles Posted January 31, 2005 Share Posted January 31, 2005 yeah, but is it necessary to have pre-load? I ask this because when I had mine replaced (under warranty), the factory were insitent that no pre-load was necessary (so I have none). www.R300.net Link to comment Share on other sites More sharing options...
Myles Posted January 31, 2005 Share Posted January 31, 2005 I'll search the archives, but I thought this-one was resolved by someone who works for a CRB manufacturer - upshot (as far as I can remember) was that they *were* intended to run with preload. Back in a bit.... ...Back! One or two of us have been in touch with INA about this and it turns out a certain amount of preload is indeed required. The bearing is designed to be constantly in contact with the clutch fingers, with a certain amount of force required to avoid any slip between the bearing face and the clutch fingers. Ford and others use self adjustment mechanisms and what have you, to put this preload on. From this thread here Project Scope-Creep is underway...

Myles Posted January 31, 2005 Share Posted January 31, 2005 Erm, I *think* yours was made somewhere respectable, but later versions by the same manufacturer were being made in Brazil. Mine was/is French. It's in the boot of the tintop (as is yours), so I can't check right this mo... Project Scope-Creep is underway...

V7 SLR Posted January 31, 2005 Share Posted January 31, 2005 Mmm, wish I'd taken a pic of my new one now. Maybe that was Brazilian. Maybe I just dreamt it. My new one looks like my old one anyhoo. Yours is wierd and strange and odd and IIWY I'd chuck it away. It's far too scary. Woooo. Link to comment Share on other sites More sharing options...
John Vine Posted February 7, 2005 Share Posted February 7, 2005 I thought this-one was resolved by someone who works for a CRB manufacturer - upshot (as far as I can remember) was that they *were* intended to run with preloadAs far as the INA CRB is concerned (F-202944), you're right. INA say that a pre-load of 80-120N is essential. Whether the same is true of the FRA174C (SKF?) item, I couldn't say. But I'm intrigued to hear that CC have changed manufacturer due to "quality problems". IMHO, there's nothing wrong with the quality of the INA CRB -- the problem lies with the way the CRB is set up. But I guess it would be a good idea to ask the new supplier (SKF?) directly whether they think a pre-load is necessary for their bearing? JV Edited to fix command error!
