Squeal in Front Chain Sprocket

Wheel Rush · #1 (**permalink**) 06-29-2008, 06:37 PM

The bike has been running for a week, I thought it was a little early for greasing, but I am getting a squeal from the clutch arm housing, with the engine off as I move the bike back and forth the squeal is coming from the clutch arm housing, in neutral the chain moves, back and forth also, so I guess its the small sprocket, is this common, if I need to grease it, do I disassemble the clutch cable? where to grease?

You can try taking the clutch cable holder out and shooting some heavy oil in there....or return it for warranty claim.

I don't know, I haven't heard it.

It shouldn't make any squealing noises though. I'd at least make the seller aware and ask what they suggest. You don't want to find out on day 31 of a 30 day warranty that it's a major bearing in the sprocket shaft that needs to be replaced do you?

Could it be something else on the bike that is causing the noise? Take the chain off and roll it, see what happens. While you have the chain off, turn the sprocket with your hand see if it makes noise and if you can feel it.

Fairracing31,
thanks I'll check it out, but for now I have my hands in it, and my question is to Bike Guy Joe, I have the clutch arm plate off and the chain off the rear sprocket, now, you are saying ? take off the chain, from the front small sprocket ? How to turn the sprocket by hand with the chain off ? the rear sprocket but still on the front ?

What about the clutch post that depresses the clutch ? I took it out, the other day I put some heavy lube on the chain, this post has a very dry lube on the depression end, I believe it is compacted with possibly clutch wear dust, prior to this I checked the clutch housing 4 days ago and noticed some clutch wear fuzz ! Do you recognize any symptoms ?

If you are speaking of removing the plug and turning by hand, "using the kit wrench", OK, but this occurs mainly in neutral, wait a minute, I know it is when the chain is moving in neutral which means the rear wheel is moving, correct ? this then I think applies to coasting correct ? Well I have it apart now I'll put it back together and check again, as soon as you tell me exactly where to squirt the oil.

I realize it's Sunday night and it's 11 pm so while I'm getting my greasy finger prints all over my key board, I really don't expect to much, but I'll be on it till I get it fixed.

Now the, "clutch cable holder", has got to be the first stop from the clutch lever on the handle bars to the engine, if so your saying (Bike Guy 31), unbolt and squirt the oil in here?

If so OK no problem, I have 3in1, and the Sunoco, air-water oil I use in the gas mix, other than that I have some Multi Purpose heavy Duty Lithium grease.

Now about the clutch lever post that slides out of the center nut holding in the small chain sprocket, should that be lubed, and or the nut and what is behind it ?

Yes that is where it needs to be lubed.......

I would use the Lithium Grease..........

Take the clutch cover off, remove the rod going into center of sprocket, and th ball in front of the rod. Lube the ball, insert in hole, then the rod, insert in hole, also grease the arm that in the clutch cover.....
