Zulfigar, thanks for the reply. I have the disc facing the wrong way but when I took the bolts off some of the washers were on the bolt head side and some were on the lock nut side, and there was no consistency to how they were placed.

I also added to my posted above about whether we are supposed to grease the centering pins and bushings on the disc.

It also appears that the torque value for the flex disc bolts are 45 Nm, but there are certain instances when there are different torque values.......why would they differ?
