This is the exact idler pulley for my Maytag/Amana washing machine.

It is not pre-lubricated and does not have lubrication instructions.  Turbine oil seems to be the suggested lubricant.  I used a synthetic low-weight motor oil in the hopes that the synthetic would not dry out or turn to gum as it ages.
