May have overtightened chain

[Mrjoolz]

Get clunking when pulling off away from lights...

I will adjust the chain this evening, but I have ridden into work today (40 miles), and just wondered if doing the 40 miles home will be OK, or will it damage the bike (front sprocket)

thanks in advance

When do you finish work? Im in from 6.15 today... pop by and I can take a quick look if you want.

[MaybeGuy]

It wont damage your sprockets, itll damage your output shaft bearings. Fingers crossed aye?

Unless you have had the wheel off and your cush-drive rubbers have gone astray...

[Jefr0]

When I had clunking on my chain it turned out to be bits of the rear sprocket coming off from where I hadn't looked after it.

Lesson learnt by me!

Check the rear sprocket for any damage.

If you have overtightened the chain and it has damaged the output shaft bearings then it is a big fun job splitting the gearbox open to change it.

[Mrjoolz]

Hiya Paddy,

I finish at 5:30 tonight and will be home by 6:30. I can pop in then.

Could it damage the bike, as I am hearing a clunk when I pull away from traffic lights a little harder.

Could it be front sprocket ?

Couldn't a clunk be an under-tightened chain?
Y'know, clunking as the chain takes up slack real quick?

More of a general question than real assistance. Am learnin' too.

[Mrjoolz]

I have read that an over tightened chain can also cause clunks as the chain bind to the sprocket or something.

Just hoping that I havent done any damage since it was Sunday that I tightened it and its now Wednesday at 80 miles a day. :o(

Ooops, just read all the posts between my original and my next post. Thanks all, I'll check and losen chain if required.

Its not a loud clunk, but a very sublte one, but I know its there, so I am probably turning it into some local building shaking kinda thing.

Best to check it out with you all.

rather ask this question, then "how do I split my gerarbox"

Its cool mate, if its tight we'll loosen it a bit. I've got a fair bit of oil too if it needs a clean and lube

[Souleh]

Just slack it off and if its only been one journey then it should be fine.

[Mrjoolz]

Think I may have sussed why my chain/bike is making noises when I pull away.

I have just watch a youtube video on chain tightening on a GS500 which has the wheel alignment brackets that slide over the spindle. these brackets have little feet which bend under the swingarm, but do not touch it.... :o(

I thought that they had worn somehow, and therefore when I was trying to check that wheel was aligned, I moved the bracket so one of the feet touched the swingarm, and the same on the other side, and then proceeded to tighten up spindle.

However apparently after watching this video, you position these alignment brackets so neither feet touch the swingarm, and there for the indicator points straight up at the notches.

therefore I think that the wheel is slightly out of alignment and hence the clunking is the chain catching on teeth as wheel not aligned properly.

Does this sound a fair assumption.

How did you line the wheel up

Hi

For the chain alignment to cause the chain to snatch I would expect it to need to be quite a long way out.

To me a too tight chain seems FAR more likely.

Don't trust the marks on the swinging arm. Get the wheel in line (string, scaffolding pole, laser point, some other reliable method) and after that just make sure you turn both adjusters the same number of flats (one flat is going to move the adjuster about 1/4mm on most bikes - far more accurate than you can see on the markings even if they are accurate).

All the best

Keith

String ? How could I check alignment with string ?

probably being thick. thanks.

Hi

Not a method I have ever used, but basically support the bikes so it is vertical and put a piece of string from the front wheel, around the back wheel and back to the front wheel so you can check the angles.

Quick google finds this which explains a way to do this better than I can

You may need to improvise to keep the front wheel straight when measuring.

excellent. I'll adjust chain as its a little loose, and then try this or alignment.

Thanks for replies.

just called local dealers to ask them about my ongoing pulsing with brakes, and they said pop bike down and they will pop in on their brake tester and let me know if its pads, discs, wheel etc...

They are also going to check the chain/rear wheel about this clunking, to see if its kush drive/ sprocket carrier bearings/ or actually chain and sprockets.

All for 15 mins labour, at £17.00

I'm well pleased with that so I will actually have a better idea of what to actually throw money at instead of purely guess work or assumptions.
