My polaris 280 has been non stop for 3 years now. Recently it has had problems running slow. I took a look and noticed the inner wheel gear was worn. I replaced the two wheels and the bearings on both wheels. Now the wheels spin slowly, but if I stop the wheels movement, they are slow to start again, if they start at all. I can give them a little thump and they will start again. What is the most likely cause for this? Do I need to start digging into his guts to replace any worn parts?
What are the likely culprits in a 3 year old polaris?
