You asked, "What is the part number for the idler gear bushing? I do not remember seeing it in the parts book just the gear assembly."
The idler gear bushing is not sold separately, but I noticed that the idler gear shaft is the same outside diameter as the pump drive shaft. The bushings are available for the pump shaft. I can't figure out the outside diameter of the idler gear bushing, but it "appears" to be the same as the pump shaft bushings. Length of bushing might be an issue. Something you might check out if you're dealing with a worn idler gear bushing and everything else is usable.
