Installation Notes Clutch replacement means splitting the tractor, so take time to inspect your flywheel surface and replace the pilot bearing if it's worn. Cable-operated systems require proper free play adjustment after installation —too tight causes slippage, too loose makes shifting difficult. Break in your new clutch gently for the first 50 hours to get maximum service life.
