[MENTION=56]Adm_rsx[/MENTION] I was working on a job site that was strictly dirt/dusty roads for the last 1.5 months. It seems its been too long since I oiled my intake filter and a significant sum of dust made it through the filter. My question is does the rotrex have any competent s that could be hurt by dust? I've seen unite taken apart and it seems its just the volute and impeller on the shaft, I can't imagine the dust actually getting by the bearing to the internals. There doesn't seem to be any damage to the compressor wheel and when I spin it by hand it doesn't feel like any grind like a bearing with dirt would feel. you can see the dust on the walls compared to the end closest to the camera. What are you thoughts, could a dust in the intake make it past the output shaft seal/bearing? Also I checked and couldn't see oil flowing into the canister visually, but if I crack the return fitting it oozes out quickly so it's defiantly circulating. Thanks for all your help so far!
