I'd be willing to pay that price for one of those, if they are available. If so, please post ordering info! Can you please measure and post the part's I.D. and the O.D.?
A quick internet search on that part no. turned up empty. Can you recommend a reliable supplier which you have used?
Derek, I just spoke with NTN engineering dpt and the C4 bearing is no longer available. They have recommended the following. 6203LLUC4/2AS. They are looking further into it and will call me back.
As I have said the person at SKF gave me all the info I needed and I told him what was there and he gave me info on their current offerings for 6203. I would be very cautious ordering SKF bearings on ebay, there are many counterfeits out there.
Here is one of several threads I read prior to doing mine and ordering bearings. The bearing Martin(from Germany) mentioned are NLA and why I ordered what I have. Anyway, good luck. https://www.ferrarichat.com/forum/threads/cam-drive-bearings.534241/
Tommy, those 2AS bearings look great. Same temp specs but different grease supplier. How much are they as I may get a few spares.
Derek, Not sure I didn't look in to it as I'm waiting on word from NTN on the best available bearing for the application., You really have faith on TNT products!!
Has anyone experimented with hybrid bearings? They are suppose to be far superior than what we have been using at least for the lower cam application.
They do look good in theory but I have no experience using them. Hopefully they have been used in other harsh environments/industries and someone has or finds good data.
Just received the spacers. Can someone confirm the way they should face? (is it correct on the image or the other way) Image Unavailable, Please Login
Some have asked about the "spring washer" aka belleville washer. There's a specific reason it's there, it's not a trivial reason. It would be easy enough and well within the capability of the factory to machine a pocket for the bearing so that it wouldn't need a spacer to take up the diff. So what is the reason? Thermal changes and gear thrust. The expansion rate of the timing cover is greater then the bearing and shaft mass, so at some point the bearing is free to float in it's bore, that's not a good thing as the outer race needs to keep from turning. Without the spring washer the entire shaft can float, also not ideal for a timing belt setup. In short it's to pin the bearing place and reduce vibration, harmonics and movement that can cause problems. Honestly it's an ingenuous setup. Thought I'd share that. Stupid thing can be a real PITA to install though.
