THE most neglected and least checked part of the bar, chain sprocket combo. Folks will spend £s on new bars and chains and their worn out drive sprocket will wear them 3-5 times as fast. Heat build up/chain de-rail/peened drive links/nose sprocket blow outs can often be attributed to this part. How many times have we heard ‘but the saw is still pretty new?’ – does not matter – if that drive sprocket is worn it is worn so take the time to check it and change it.
