AC Compressor Bearing Failure

[zsarnold]

I just replaced the bearing in my AC compressor pulley. I cannot get the bearing back onto the compressor shaft, what are some easy ways to get it on? Also, the groove for the snap ring to hold the bearing is broken off. Is it a big problem if I do not have a snap ring? I also think that my clutch is worn out and needs to be replaced. One side of the plate is shiny metal and has a groove while the other side does not. I have a 05 Liberty Limited 3.7L. What size belt would work to temporarily bypass the AC compressor while I wait for new parts or get it fixed?
