So I replaced the broken hoses going to the air pump, and re-connected the wire to the pulley clutch. The previous owner had disconnected it, I had assumed because the hose was shot anyway.

The thing sounds like bolts in a blender when the clutch engages.

1) How important is the air pump?
2) Is it worth replacing?
3) Will the pulley bearings hold up even though the inside sounds like hell? It sounds fine when it's unplugged.


I guess what I am really asking is do I need to replace it? Will my Caty clog up without it? I'll bet they're ungodly expensive.


Thanks!
