Can someone do a quick measurement for me? I need measurements of the front hub dust covers/grease cups used on most of the Wheelhorse Tractors. (300, 400 500 & C-Series) I don't have one on my bench anymore and the one I wanted to measure on my C-175 won't budge and I don't want to ruin it just to measure. I have none on four of my machines and I'm tired of the crap they pick up. I need the Inside Diameter The Outside Diameter The Depth or length Didn't see anything on the dimensions while searching the site. Thanks in Advance!
