I have washed aprox 95,000 cars with this chain. We have had issues where the chain will skip/hop teeth on the sprocket. We have replaced the spocket--No help! There is a lot of slop with the rollers too. Its to loose and then we take a link out and it gets too tight and the roller raiser gets jammed!!! Spoke with another operator that said he has had it occasionally happen to him. Any one have any experience that can help?
