The right side wheels rolled forward about 3 inches and stopped (has 1/2 inch play each way). The left side rolls forward and backward about 5 inches each way. My other 743 rolls 1/2 inch each way on both sides. Any ideas on what wrong and how to fix? I know chains stretch but 5 inches is alot isn't it?   Also checked chain case oil and oil gushed out so I know one or both of my travel motors have a bad seal.... Thanks guys....Mike</p></blockquote><p></p>
