When your clutch starts slipping under load or won't fully disengage when you're trying to shift, you're losing power and wasting time—problems no farmer can afford during the busy season. This complete 12-inch LUK clutch kit is designed specifically for cable-operated clutches and gets your 390, 4225, or 4235 back to transferring full engine power to the ground where it belongs. What You're Getting Complete LUK system with matched pressure plate cover and clutch disc for consistent performance 12-inch (300mm) diameter provides the torque capacity needed for heavy draft work while keeping pedal effort manageable Cable-specific components engineered for the mechanical characteristics of cable actuation—different from hydraulic systems All necessary components included so you can do the job right the first time Direct replacement that fits exactly like the original equipment Built for Real Farm Work This kit fits Massey Ferguson 300 series (390), 4200 series (4225), and 4300 series (4235) tractors that handle everything from loader work around the barn to pulling heavy implements through tough field conditions. Whether you're running a disc harrow, operating a manure spreader, or doing heavy cultivation work, these tractors depend on their clutch to handle serious torque loads day after day. LUK Quality That Holds Up When you choose LUK, you're getting OEM-quality components throughout—both the pressure plate cover and clutch disc carry the LUK name, ensuring matched performance characteristics . This isn't a budget kit with mixed brands; it's engineered as a complete system that handles the heat, pressure, and constant engagement cycles that come with real farm work. 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.
