Typical grease-gun grease that you use to lubricate your tie-rod ends on your automobile isn't compatible with the engine oil and may actually prevent engine oil from flowing thru the SC parts as a result, blocking passages causing parts to rapidly burn up (flowing oil cools as well as lubricates). Also, it's very sticky when you apply it so it will help hold parts together (such as needle bearings to the shaft, in the SC!) while you assemble things. it dissolves into the oil once the engine is up and running. I cannot imagine what happens if you put the clutch washers in on the wrong sides of the drive gear, but I suspect a bad experience will follow shortly thereafter.ĭennis, I believe what makes the grease special is that it's compatible with the engine oil and won't harm the engine internals. When replacing the clutch washers you MUST note which washer went on which side of the drive gear, as the shaft diameter is slightly different on either side of that gear (it's just slightly conical). Note: The clutch washers appear to be identical to the naked eye, but their inside diameter is actually slightly different if you hold them against one another and look closely. They're only designed to last for a finite amount of time and then they must be replaced or run very real risk of major catastrophic engine failure. The parts inside the SC (the shaft, the bearings, etc.), and not just the clutch washers in it, are wear items just like the brake pads and rotors on your automobile. It's not optional, unless you want to end up buying a new engine instead. these clutch washers are for an entirely different purpose and are designed with vastly different materials, they are NOT just plain metal washers! I cannot stress this enough, DO NOT replace the clutch washers with just any similar sized flat metal washers you can obtain!!! There are metal washers, and then there are METAL WASHERS and the metals in them are not the same.Īlso if you're at 100 hrs, you need to completely rebuild the SC not simply replace the clutch washers. Worst advice EVER! These SC clutch washers are NOT anything like the metal washers you buy at an auto parts or hardware store to put under the head of a bolt.
