I purchased my pump as a hobby, and I am now tackling my Veeder Root 2002E computer. I've found I have a few bad "Reset Disc Pinion Group" which is a little plastic disc that goes between the computer wheels to aid in what else, reset. Using the VR-10 manual, these carry a US part of 77481-006. I can't find these on google. Should I just buy some wheels on eBay, or can my local gas distributor get these, and will they generally sell to the layperson?
