INA vs Torrington any way to tell?
Recently, I purchased a 99' Heritage with a build date of 3/99. By the way, I love this bike! The parts book needle bearing part number is listed as 9058. Based on the part number, is there any way to tell if it's a INA or Torrington bearing? I heard that the MOCO changed bearings sometime in 98' Is this true, or wishful thinking? TIA

And...we all know that you should yank it out and install the Torrington if you even have half-a-reason and more especially...if you change cams to an aftermarket. I can attest to that after a $3000 plus engine rebuild due to parts of that little INA job floating all around in my EVO. I bought a dresser with less than 10K on it and the guy swore it was box-stock. I guess he forgot about that aftermarket cam he stuck in there in that INA bearing and I paid the price for his memory lapse. Doesn't matter if it's an EVO or a Twin Cam...get them out when you get the opportunity.

The easiest way to tell is if you have shrapnel in your oil!!!
If you do,it won't take long! Maybe a day or too.
The good news is I'm pretty happy with my "forced" up-grade to a new,bigger cam,shiny new oil pump(the shrapnel ate it up),adjustable pushrods,and new JIMS lifters..........$1250 in parts.......one day working on it.....all because of a .49cent bearing!
Having been down the road,I'd plan on replacing it just in case.
Half of the time spent was cleaning out the debree of the failed bearing.

The INA is used in the transmission also, with no problems in that application, so volume buying is a factor. Using the caged bearing speeds assembly at the factory. Quality, obviously, is not a concern.
The uncaring attitude about quality extends to the Twin Cam also. They use a larger INA on both ends of the crank, with predictable results on the power side, and they have stopped using bearings altogether on the pinion end of the camshafts! They've gone to a two-piece frame on the touring bikes in order to expedite assembly of the trike...... I'm just waiting for one of those to crack in half on the highway.
