front pulley trashed
« on: Today at 03:51:39 AM »


My 2017 FX (purchased new in 2019) has about 14,000 miles.  I had the chain kit on it for about a year and then put the belt back on when the chain was worn out.  I heard some unusual noise, kind of clicking like, particularly when regen would kick in for a week or 2.  I checked belt tension and watched the wheel and belt with the bike on the track stand and the motor running.  Unfortunatley, I didn't see anything.  It failed on the way home the other day and I found that all the splines in the pulley were nearly gone.  You might be able to see it in the photo.  The shaft on the motor has a little damage but I think a new pulley will still work.  I was at the dealer today to order it for $101+ and was told it may take 2 or 3 weeks.

Just wondered if anyone else has had this problem.

That's a very surprising failure mode, I've not even heard of the torquier R models doing that. Generally it's the belt that is the weak link. Interesting that you have the 20t and not the 18t pulley (which means even less load on it), I assumed the 6.5 would use the smaller pulley like the 7.2 models do. You could change your order and get a little bump in torque, presumably you have the dongle to adjust the speedo to the different ratio and you had the chain kit or you have the dealer do it.

If I remember correctly the instructions say to use Loctite 620 on the splines when assembling. Maybe check before you put the new one on.
