Broken rubber on front sprocket - zirconxi_imp - 05-23-2020
Recently i just found out my front sprocket had a rubber damper on it and its now broken. The sprocket teeth are still usable. But the rubber damper are broken and currently hanging and dangle around inside when the sprocket turn. No funny sound or blocking anything. Do i have to open up the sprocket cover to take it out? Or can i wait till its time to change the sprocket
The orange pointer is pointing at the loose rubber. Theres another part on the inner side of the sprocket.

That is just a sound deadening buffer.You do have to takeoff the sprocket cover to get to it, but other than trimming off the flap there isn't much you can do to it. Aftermarket sprockets don't have that. Personally I wouldn't worry about it.

I don’t know if it can happen, but I’d be worried about it damaging the seal.

Ok, 45 minutes to get the broken rubber out. With 30 minutes trying to remove the inner part.... Done some cleanup on gooey chain grease, and ready for ride...

Nice job! I figured you’d have to take the sprocket off. Glad you didn’t.

In that bottom pic, the front sprocket looks like it might be due for replacement soon, The teeth are starting to curl.

How many kms on this sprocket???
RE: Broken rubber on front sprocket - zirconxi_imp - 05-24-2020
Ya, I notice the teeth getting into shuriken form. Its been in service for more than 36000 KM. I had check the chain and sprocket mating and it is still good. No gap when pulling chain away from sprocket. The chain also don't have any kinked link. Maybe can last another 5-10k.
