Oh boy, cam bearing shelled out...
06 E-Glide TC88... Lost oil pressure, made a whole lot of noise. Pulled the right side of the motor apart last night, and found some not very good news... the rear inside cam bearing had lost every needle, scarred up the cam, and actually ate through the bearing outer shell in one little spot. I had already ordered all new cam plate, bearings, timing gears and chain, Andrews 26 cams, (tools to remove & install bearings), oil pump, etc, and planned on replacing it all since I was in there, turns out it's a necessity. I found the needles, broken, ground, whole, shredded, in the oil pump (which explains a lot) which is completely shot.
My question is this: now that I know all these little needle fragments were loose inside the case, should I tear apart the other side of the motor and check out any damage that may have been done on that side? Or would all those fragments have stayed in the cam side of the motor? How is the oil routed from the pump?

That's kind of what I thought, especially with the amount of metal I found on that side... that and the fact that when I drained the oil out of the crankcase, there were no pieces stuck to the drain plug magnet... I haven't pulled apart the oil filter but I'm sure that has plenty of shrapnel in it too... does the oil pump pump all the oil directly to the filter before routing it throughout the motor?

cam bearing failure
Pull the plug out of the bottom of the crankcase an flush out what u can. Pingel makes a screen kit u can install on the scavenging side of ur oil pump to eliminate the chance of sucking up any more shrapnel.

The only problem with flushing out the crankcase is that the drain plug boss is higher than the crankcase floor. So, if say an intact needle bearing roller was laying on the crankcase floor, there is a good chance the flushing would not push it up and over the drain plug boss. However, flushing is about the only option you have now if you don't want to split the cases.

well this story has a very unhappy ending... i'm afraid my little tc88 has met it's demise. I rebuilt the cam side of the motor with all new stuff, flushed what I could, hoping the damage was contained to that side of the motor. I flushed, buttoned it up and put oil in it, planning to warm it up and change it right back out again, but when I started it the motor sounded like someone had put shredded up tin cans in the crankcase... so something is bad, very bad in the crank side. I'm going to go sulk for a while, try to figure out my next move. HD's rebuild program? Used motor out of a wrecked bike? Don't really have the funds to just drop an S&S in it, and I'm not sure I want to anyway. Even with my little mishap I'm still sure that the 88 is still one of the most reliable motors out there, and with a breather, exhaust, and a mild cam will run respectably... I've really not looked for motors before and don't know where to start, any suggestions would be appreciated... thanks gentlemen

That is bad news, sorry for your misfortune.
Pulling the lower unit and splitting the cases will tell you where the problem lies. Then you can throw it back together and send the lower unit to Scott or Hoban Brothers or whomever you like for crank replacement. When you do put it back together, it won't cost much more to increase the displacement to 95" or 98".
