So grumpy,i have been on the mtd site and the eaton hydro diff site with no luck on a schematic break down on the diff before i start to pull it down,can you or bruce help me out.i can just replace the outer bearing but the internal spider gears might have dropped down or out of alighnment,now that its out i would like to do a full and proper job because i might use this as my main contracting mower.i have heard that these hydro units cost $2000.00 plus...ken
