Am i looking at a big job to replace my chaincase in my 1996 Polaris 600. Havn't got it apart yet but when i put fluid in it's slowly leaking out the bottom. Could it just be a gasket maybe??
Pull it apart and inspect the edges for chips or cracks. Most likely the gasket has a crack in it. Get a new gasket and put her back together maybe use alittle RTV silicone on the new gasket.
