I don't think so. No bearing should let loose like that. That thing let loose in a bad way. You can put it back together with a new pump and hope for the best or break it down and clean the whole thing out.

Am I seeing the word "Torr" at about 9:00 on the bearing face? I see no signs of the plastic cage that holds the rollers for the INA bearing.
Also see some similar markings on that bearing that match the markings of the 'torr" bearing the link below. Regardless, it looks like you still have some missing rollers. Sorry man.

I think you are right about it saying torr. The shop seems pretty solid. I would be very surprised if they didnt know the difference in the bearings. In order to lock up the oil pump the roller had to fall into the crankcase correct? If I can flush with kerosene and six more come through the same way then Im good. I dont want to split this thing open and put it back together without rebuilding it. This bike is in exceptional condition so its worth saving but IDK how much is too much when its an extra bike. The shop suggested finding a used engine.

93' ultra classic lost oil pressure. the shop said it was the cam bearing that failed and the needles siezed the oil pump. they said that they could only find 23 of the 29 needles. my question is how possible is it to recover the rest of the bearings. I'm assuming they must be in the crank case.

If you knew exactly how many rollers are missing you could pull a cylinder and "go fish" with a borescope and magnet. But without a full count you'd be gambling.

Washing it down with kerosene or whatever is not going to help you clean out the case the whole deal is there's a scraper back there about the 2:00 position that the flywheels carry the oil to.. It has minimal clearance and that scraper is what feeds the oil pump. There's no way you're going to wash out and try to get any left over pins out. You're going to have to split the cases and it's not that big of a deal.. It's not like you're going to be resetting the clearances on the timken bearings to make sure the wheels are centered.. You're just disassembling and putting back together.. while you're disassembling a good look at the pinion side bearing and the sprocket shaft side bearings the timkins, and if you see any funny wear on them due to metal traveling through the motor then it's possible that the crank pin has damage because the crank pain gets oil before the timken bearings do.. Get yourself a service manual and do it by the book.. It's a lot simpler than you think. I would definitely start by checking excessive play in the rod bearings on the crank pin that would be your starting point... You would be stupid to assume that you can just try to clean it out and throw it back together. Ain't going to happen.. listen to these guys.. They have a lot of knowledge...
And yes that looks like a Torrington bearing.. The best thing right now is to disassemble the oil pump and post up some pictures...
