Ive got an 06 vinson 500 with 900 miles on it that just developed a belt issue. I have been using it pretty hard this winter pushing snow and it has worked great. The other day we had some warm weather and I was pushing back some piles then I started to loose power like the belt was slipping. During one hard push I smelled rubber burning so I parked the machine. I took the belt cover off today and the all looks good except there was a little oil in the case and the drive pullies and belt were oil contaminated. Any idea where this oil could have come from. I am going to clean everything with brake cleaner and put it back together. Anything else I should check before reassembly. Thanks Ned
