Greg, was the part number 6655K16? If so, all the bearing surfaces are hardened steel. The bearing is actually three separate parts, unlike a standard radial ball bearing. There are two flat washers which are the bearing races. Between them are the balls, which are contained in a small nylon disc. The balls are free to rotate, but they cannot fall out of the disc. The nylon disc does not bear any load, so it will last forever in this application (the bearing is rated for 33 lbs at 2500 rpm). You said you also ordered a needle thrust bearing. Did you also get the two bearing washers with it. They are sold separately for this part (the 6655K16 bearing includes the washers). Neither bearing can be used without the washers. If you have both complete sets, try each one and use the one that,s smoothest. If it's a toss up, use the needle. Post some picks of the alt assembly if you can.
