Picked up a 1998 Big Bear 350 4 x4 , drove it around but felt clutch was spinning as it was going up steep hill. Simple would not make up the hill.
Drove ATV into garage pulled the clutch cover , and decided to replace the friction plates, and springs. Centriful Clutch looked ok. Put it back together
filled It up with Yamalube 10w 40 3.2 quarts. Started right up placed it in reverse and nothing , did not move fill like its in neutral. Moved gears inot 1st , 2nd 3rd nothing did not move.
Pushed it to see it gear , acts loike it in neutral. Pull the clutch cover all the gears will spinning , could I have put something back on wrong in the centriful clutch bear , stuck
in neutral, new clutch disc not working?
