Late '79 tranny. Replaced the spacer, main seal, and shaft seal. New PBI sprocket, and one of those sprocket nuts with the oil seal in it. My question is, is it possible to tighten too much? There's clearence between the back of the sprocket and the tranny case, and the sprocket turns without hanging up, the mainshaft turns freely, but when I turn the sprocket by hand it seems pretty snug, it just seems like I may have tightened it too much. Again there's no grinding or hanging up it just feels tight. Am I over thinking this or do I have a legit concern? Any opinions, suggestions?
