Chain and sprocket replacement

[CarlS]

I replaced the chain and both sprockets on Mae Lyne's T100 today. Unless Dilligaf had replaced the chain and I don't think he did, we got 24,000 miles (38,624 kilometers) out of the chain. It was definitely due for replacing.

The job wasn't too hard except for the necessity to dismount the hack to get to the primary drive cover. I elected to stay with the 17 tooth primary because of pulling the hack. I think if we take a long road trip, I'll convert to an 18 tooth. The 17 tooth works well in the urban environment where we live now.

While I had the hack off and the rear wheel off, I replaced the rear brake pads, They were a little over half worn. When I replaced the front brake pads about a month ago, they were worn down to nothing - just before damaging the rotor.

It had the original chain when she left me.

How were those sprockets after 24,000?

I'm only on my 3rd chain and 2nd set of sprockets on my (70,000+ miles)1996 bike! Of course my riding season is short here too. The only reason I changed sprockets at all was to make the bike a little bit "taller" / less torque.

Gary, I did not think you would have had to replace the chain. I am well satisfied with 24,000 miles out of a chain.

AJ, the sprockets were pretty well worn, especially the rear sprocket. I definitely could not have gotten another 24,000 miles out of them. I only got 18,000 miles out of the original chain and sprockets on my T100. And that is about right considering Gary had put 9000 miles on the T100 before we bought it. When we lived on the preserve, the sand ate chains and sprockets. Now that we no longer live on a dirt road, we should get better life out of the chains. 22,000 to 30,000 miles for a chain seems to be the norm for the Bonnie based on what I have read on various forums.

Sounds about right for most bikes actually.

 

[CarlS]

I thought that might be the case. I know the sand drastically shortens the life of a chain.

That's surprising. Was it an alloy rear? When I did mine, the front showed much more wear than the rear. I attributed that to the fact that the front turns more revoulutions. I actually used my rear over again because the parts man ordered me the wrong one. I flipped it around backwards, but didn't really notice any wear on it.

 

[CarlS]

Both were well worn. There is no doubt we needed to replace them. It is the sand and crushed shell roads where we used to live.

Seems like you did very well on them Carl. Funny I never gave the life span of my one a thought up and till now, still got a few miles to go before I reach this :y114:

Was noticing the chain on my 2004 black bonnie today and went to the forum. I've noticed that the outside of the chain has begun to wear off some of the black paint. Is this normal for approx. 10,000 miles I have on the bike? I lube the chain with a wax about every 500 miles. Think I need to check anything else?

My chains don't have any paint on them; but in 10,000 miles you should be seeing some wear, really abrasion, along the side from the abrasion of sand and stuff from the roads.
