Didn't get much response to this question in the Apex section so posting it here also.....
Just looking at the parts fiche and the service manual and they appear to show a different # of washers/spacers on the exterior of the chain case by the brake rotor.
Top pic is showing what I remember disassembling from my sled
2nd pic is from the Apex service manual (showing circlip, 1 spacer, then the rotor...which I know is not correct). They do not even show the spacer between the rotor and the large spacer w/ t-20 torx that sits partially recessed in chain case oil seal.
3rd picture if from the parts fiche from Yamaha's website (showing circlip, 2 washers, spacer, then rotor). Part #'s 3,7,6,& 5.
What gives? What is correct?
