METAL DRIVE PLATES

Metal Drive Plates
Since proper clutch operation depends on all components working together efficiently, the metal plates must be the correct thickness and absolutely flat. Most O.E.M.'s produce metal plates that are identical, except for thickness, for use in different models. Always measure the thickness of replacement metals to assure proper fit. Some models may require more than one thickness metal in the same clutch pack. The metal plates may be re-used if they are the correct thickness and meet flatness specifications. If they are discolored from heat, show "hot spots," or are in any way suspect, replace them! Some models utilize a spring or dampener plate. This consists of two metal plates riveted together with a wave-washer between them. Always check the rivets and replace the plate if they are loose. Remember, small pieces of metal floating around in your clutch assembly can lead to costly repairs! Many off-road models come stock with aluminum metal plates. These have a tendency to wear quickly, polish to a high sheen, and "muddy" or contaminate the oil. Replacing them with Barnett steel plates will keep the oil cleaner, increase flywheel effect, and last much longer!

When installing steel drive plates, notice that there is a rounded edge on one side of the plates and a sharp edge on the other. It is important that you install the steel drive plates with the like edges going the same direction. It doesn't matter if the rounded edges or the sharp edges are facing outward, as long as the edges are facing the same direction.
