I need to change my drive belt. The rear sprocket looks real bad with the flaking chrome so I will certainly change it too. I have about 70k miles on it. It is a 2008 FLHTC.
In the old days of chains and sprockets we changed all 3 components at once. Do I need to change the front sprocket at the same time as I am doing the belt and rear sprocket or should I just wait to see if it has damage. Or is a given that I should change all 3 components always.
Thanks for your replies.

 

Is the belt damaged? If not, and the flakey chrome is just driving you crazy, I'd just change the rear. Don't forget new bolts.

 

Yeah. I am mostly doing this to change the belt. Just wondering if I should order all 3 components or just look at the drive sprocket when I get it apart.

 

These days are not the old ones! Put that behind you and look to the future. If your drive belt is sound and has no visible damage I would leave everything as is and ride on. However if you are dismantling for another reason, by all means replace all three. Some owners have done over 100k miles on the original belt and pulleys, so you are not there yet!
