snowmobile chain tension

Q The chain on my Polaris Edge gets loose then tight when rotating. Is that normal? Or do I need a new chain and bearings for it? - unknownpoo
A There are a couple of possible issues with your chain tension. First, the shaft could be bent and causing the gear to move up and down. Second, the chain could have a ‘hard’ spot that will hinder the rotation at that point. Third, just as your suggestion the bearing could be bad and not the chain. – Jason Houle, Straightline Performance
