Another Sirocco CDL "noise" topic!

[crE]

I've just noticed today that when I'm pedalling (with or without power, over 8 mph or so) on thr right leg pushing down I am getting a squeak. Best way I can describe it is a creak. Like a door creaking. But very short. It doesn't happen with thr left leg...

Is something too tight? Loose?

Just as a precaution, you should tighten the crank bolt a bit. You have to prise off the plastic cap to get at it.

 

[crE]

By crank bolt do you mean the one at the stem of the peddles?

crank bolts:

Tighten it (on the squeaking side) until it stops squeaking.
You need a long handle 8mm allen key like this one:

Thanks I will pick one up the weekend. Thanks so much for all the help

It's possible it's a creaking saddle. Try pedaling out of the saddle first to see if it still happens.

 

[crE]

Funnily enough John I did try this because I thought the same thing. I found it difficult because of the weight distribution of the bike makes it a little unstable. I did however do the "all the single ladies" dance without pedaling and don't think I heard any creaking! I will investigate further...

My Ncx (expensive) sprung seatpost sounds like a sparrow on steroids now the weather's stayed dry for a while

correct technique for tightening crank bolts, remove said crank or chainwheel, you need appropriate crank remover tool,clean crank and spindle with a degreaser, refit crank, tighten crank bolt till it is firm, then remove bolt again,give a light tap with a mallet or hammer and scrap of wood, reinsert bolt then tighten then nip up.

The reason to do this is to make sure that the crank is firmly seated, when you tap home the crank it makes sure it is firmly engaged, better for it to be too tight than just tight enough!


It is customary to return a bike to dealer if bought from a LBS for them to check it over after a 100 miles or so, for them to check every thing is tight and adjusted, thus this may be why you are getting noises !

 

[trex]

it's good that you remind new e-riders to check every thing is tight and adjusted after the first 100 miles.
crE has probably done more than 100 miles already and will have to do this himself, he bought his bike by mail order.

Thanks for the advice. Will check my wife' s and mine before the next ride.

 

[crE]

Well. After tightening it worked without the creak for a bit then started creaking again. When more pressure is put on the pedals. I went to check them again and they had loosened somewhat. I then re tightened. But they are squeaking again!

 

[trex]

does the creaking come from just one crank or both?

 

[crE]

It appears to be one or the other. It does not effect the ride in any way though

 

[trex]

could you make a 12 o'clock mark between the middle of the crank bolt and the crank with a marker pen, so that you will know if the crank bolt spins out in relation to the crank?

 

[crE]

Great idea. Will do!

 

[crE]

The creaking is starting to really do my nut in.

Well I put some whiteboard marker on the crank like so...

After a 10 mile ride it appeared the outer markings had disappeared throughout the ride. So I can't confirm anything there.

I've tightened them as much as I can without the allen key digging into my hand. But yet the left pedal is still creaking when putting any kind of load on it.

I unscrewed the left bolt and this is what it looks like... doesn't look great. Could just be cosmetic, I don't know...

These bits proceeded to fall out upon loosening the screw. Plastic...

Half way through my ride I noticed the two cranks stick out differently. The left more than the right...

Can anyone help me with my woes?

Nothing that you've shown is anything to worry about. The creaking is annoying. I've had it on several bikes. The Octalink cranks are the worst. Normally, it just goes away after some time. When you screwed in the pedals, did you nip them up tight?

Use Tipex to mark your bolt if you think it's coming loose.

 

[trex]

there should not be any plastic or grease inside the crank bolt hole. The debris seems to come from the bolt cover but the shape of the debris does not look like from a plastic ring.
you should contact Woosh support, asking to borrow a crank puller, a left crank arm and a new crank bolt. If it fixes the problem, great, if not, send back the old pieces for them to work out what's wrong.
As d8veh said, it could come from the left pedal. Do it up tight just in case.

 

[crE]

The pedals? I can't remember now. They are hand tight I believe... would this have an effect on the crank?

Is it worth removing both sides and realigning? If possible..

Thanks d8veh
