how do i fit new drive belt to trekker 50cc?

ok i take it he transmission cover is off?if so then make sure you dont disturb the kickstart lever.you will see a round thing to the left(variator) and a round thing to the right(clutch bell).you need to undo the nut on the end of the crankshaft that holds the variator on.its tight and i use an impact gun but you can hold the variator and aundo it with a ratchet and socket but dont damage it.once its undone pull the belt off the crankshaft and then pull it out of the clutch sometimes the clutch may need to be undone and moved out a bit.refit the new belt in opposit of removal and make sure you put loctite on the crankshaft threads and nut or it will fall off and cost u.do it up TIGHT !
