I've got some main bearing numbers here, I'll dig them out and put them up. They are specials due to the bearing contact angle and cage construction etc. Bought them from a bearing supplier. Here you go. Made by RHP Bearings. 7207 X2 ETN and 7307 X2 ETN
They come in a RHP box, instead of a Ducati one. They are not an improved part, just an equivalent one. You MUST get them with the same suffix as the ones I've listed. A bearing supplier can get them, they are a special order. ie. non-standard.
You might find this link of interest £65 for both bearings. Below is an extract from my invoice for my engine rebuild you can see the comparative Ducati prices.

That is brilliant, please DO put this info into the "alternative parts" thread: http://ducatiforum.co.uk/f41/alternatives-genuine-ducati-parts-594/ A lot of people will be needing this info I think! br Jim
When I contacted them to buy the bearings from them (found by google search) they didn't have any. They may have them in again.
Dear All, Sorry for a late update but i was "lost in space" lot of work behind me also my wedding but finaly saturday i disassembled my 999 engine and i found the biggest shit what i ever seen. Maybe you remember that i bought other engine because i dont wanted to weld the crack which was on a back side of the cranckase. After the dissasembly i found weldings on my engine and also the reason why my bearing damged if you will check the picture you will recognize the problem imadeatley. To buy the bearings its no problem because all bearings in the engine are from SKF and i have cotract with a supplier of SKF bearings.This double row bearing its around 35eur. Biggiest headache i have because of this engineblock, lot of crancks are in and i dont want to by another engine or block. I will try to give for my friend who will try to weld it more professionaly like it was made and i will see what will happen. I will invest more money to this bike like to my previous japanese together.
personally I think it is either a brave or stupid man that tracks a ducati. ironic they are superbikes with a race pedigree that just arent strong enough for track use
@xbr, don't weld those cases - they will just break again IMHO. Get a set of sandcast cases - they are stronger than cast and won't let you down.
Guys, i cant trust any more for those bikes i will try to solve it but as i sad i am bit pissed of because i alreay invest a lot into this and i stil have a big piece of shit. By the way i already searched another engine block but how can i be sure that it not will be again some kind of cracked shit. What do you think under sandcast cases sorry maybe because of my english skills i dont understand. Where i could look for it?
the sand cast cases are made in a mould from sand. To make the cases/block you make one mould, pour molten metal into it, then you break the mould to get the cases out. They are much stronger than standard cases and were used on all the race bikes, legally or not! To me, the cost and effort of rebuilding a motor means that I must use the best components to reduce the possiblity of failure.
Jerry, with all due respect, it rather sounds like you've just added some weight to Phill's argument... :wink: Not that that will stop me tracking my 999 cheers, Dom
Im now afraid to take mine out the garage , oh i did yesterday after a month or so , back in love . But seriously are there any high milage 999s out there that havnt popped their internals ? Mines done 15 250 miles .
what a stupid suggestion frankly. he would then need 104mm pistons R heads and barrels as the stud spacings different and the base or S heads wont fit as they are 100mm. and a whole host of other expensive stuff to convert it over, crank etc or.... like basically a complete R engine lol
the 996R testastretta and 998S first series have sandcasted crankcases which are made for 100mm bore. I have got an set of 998rs 100mm sandcasted cases for my 749r with 100mm bore.
Phil, as MrFurry says, the first 996R motors and some of the 998S motors were all sand cast. My 998S motor was sand cast and I've got a set of 100mm sand cast cases in my cellar. They're not cheap now, but they are the strongest cases you can get for a testastretta motor. If you have a set, they are exactly the same as the early 998RS cases. You can run these cases as a 749, 998 or stick a 996RS crank in and you've got around 1100cc. So, basically, lol :biggrin:
I tought the these cases are already moulded so now i am wondering a little bit. How thez are done at the moment. Yes you are right regarding the best components but dont forget that not everybody can invest same amounts into the motobike.
