[QUOTE="mshrout, post: 1447065, member: 98055"] per the Manual, measure in 4 places around the friction plates. friction plate 1, 3. thickness. 2.90-3.10 mm, wear limit 2.80mm friction plate 2 thickness, 2.92-3.08 mm. wear limit 2.82 mm. metal plates thickness. 1.90-2.10mm. warpage limit .10mm. also check for blueing on the metal plates, indicates heat and usually warpage, but not always. manual suggests replacing either friction plates as a set and metal plates as a set. but you can do your measurements as above. maybe only need several replacements, but I only like to do stuff 1 time, not patch it. If and when you need full power and rowing thru the gears, it may (unknowingly) let go and engine just revs, leaving you in a tight spot. do the inspection and if any doubt on the plates and friction plates, replace clutch pack as kit.
