Jeff, Just one metal plate on the Stihl's. Usually two nylon sliders on the inside of the clutch cover take care of the outside. Good idea to remove the flat head screw on the inside metal guard and blow that area out with an air compressor. Over time, lots of gunk builds up behind it from the saw dust and oiler and it can slow or all together stop the oiler from working properly. Just be careful you don't blow the gunk back into the oiler and plug it up. GLWS Guys, Jeff is about as conscious and as strait shooting as they come- buy with confidence!
