Ok we figured out the shearing bolts problem on sprocket so now the next problem A year ago we changed the front oring on tensioner where you pump in the grease to tighten track. Now another seal is gone and tension on track is lost. We assumed it was same one but when we started cleaning it up and looking it is not. It appears that the grease is coming from the ram that extends into the coil spring. Any suggestions on where the seal or oring is that has blown and how to get to it? Thank You
Send me a PM with your email address and the machine Serial Number. I'll fire you off the Parts Manual for the tensioner cylinder plus the disassembly instructions.
