Ratteling sound from engine solved!!! YAHUU - 9/13/2006 5:24:02 PM

Some may remember that I have had a lot of problems with rattling noises from my engine though I had replaced the CC and the CCT, especially when the engine got warmed up...

At last I found out. This guy from Denmark I visited regarding this problem told me that it might be the balancer that needed adjustment (and I went, "what the F... is the balancer" so he explained to the younger and unknowing novice

).

He said that it should be adjusted at every service.

Got home and adjusted the balancer according to the CBR1000F manual, chapter 10 page 4... Ratteling noise redused by at least 75 %, if i tighten the balancer even more than now, the ratteling sound disappears comepletely, but is replaced by a squealing kind of sound from the balancer, probably due to the fact that it's tightened up, not loud but it's there...

But I don't know if that is any problem though??? Anyone know about that ???

Bottomline is: THE RATTELING SOUND FROM THE ENGINE IS GONE, and that is just sooooo very very nice, and all done in a 30 minutes...

So all of you guy's that have the same problem, try this before everything else is done!

Great Noe, this information could help others in the same situation. I didn’t know that the balancer was adjustable on the Hurricane.

There is a similar adjustment on the Bird, or two adjustments since the engine has double balance axis. As I read in that manual it said - adjust the balancer(s) until a wining sound, which occurs in a certain position, disappears, but not so much that gears on balance axis begins to clatter. There was also a warning for to tight adjustments giving some wining sound all the time. In that situation gears would be too loaded and wear out very quick.

It is great that the problem on your bike is finally solved and strong of you to find a solution.

Holy crap man I need to do that. My manual dosen't show how you do it. Would you explain where it is and what to do for me? Pleeeeeze?

In addition to the rattle that Dad describes my balancer shaft caused a vibration at the bars strong enough to numb my hands in just a few miles of cruising. Adjustment took care of the problem, but to totally eliminate it took overtightening, so I'm living with a little tingle around 5,000 rpm. The vibration is getting stronger with time though. If another go at adjusting things doesn't work I may end up replacing the rubber pads on mine this winter.

Hey that sounds good.
I have a rattling sound, when the bike is cold.
It has increased since I got the bike in may, I have driven about 10000km on it.

I´ll check that out soon.

R1000:
Did the Blackbird say anything about if the engine had to be warm or cold when the wining sound shuld be gone ??? I can adjust is so the wining sound it very slight when warm, but distinct when cold or distinct when cold and non existing when warm, but then the ratteling returns...

Backtalk:
Like DAD says; It's done on the low right side of the engine. You have to remove the right side faring to acces it. I found DAD's description a little hard to follow, but when I know how it is done it's easy to understand.(did that make any sence???)
It's a bit hard to explain and a manual is needed. Someone on this site once oploaded a manual so you could download it. I don't know if anyone could uploade this manual, because with my limited knowledge about computers i don't know how to do it... Sorry!

Oelhunden:
Does the ratteling sound disappear when your engind gets warmed up ? If so it could be the CCT instead of the balancer, which rattels when warm... At least in my case.

yup, and I know it is known to be the CCT, but can´t hurt trying to adjust the balancer.

Here's what my 1990 Honda manual (page 10-9) states: "Adjust the backlash while the engine is cold. Loosen the pinch bolt and turn the shaft counterclockwise up to dead end and back off by one graduation. Apply a locking agent to the threads of the pinch bolt and tighten it securely." Does "up to dead end" mean until it stops?

Noe,
I'm so happy right now I am crappen twinkies. Went out this morning and found the adjustment. I tightened it up to the point where it starts to wine and then backed it off to the quietest point. I lost about 2/3rds of the noise and it stops all together as the rpm's climb. I will need to buy the rubbers but this will work until snow flys.
Thanks for the 411 on this adjustment.
My Best, BT

The Honda manual for the Blackbird say the engine must be warm before adjusting. Then adjusted until one can hear a whining sound, and then adjusted so the whining disappears but not as much so you can hear a clatter. They also state that the optimal adjustment is when the balancer gear runs at it quietest. Finally, vary the engine speed and check that there is no unwanted noise.

I would certainly adjust it so it is silent with warm engine, but in first hand go strictly by the Hurricane manual since the mechanical design can differ between Hurricane and Bird. I've looked in the CBR 1000 F manual to, where they say - adjust to end position and then go back one mark, or something like that. Doesn't that procedure quiet down your engine?

If i follow the CBR1000F manual, the ratteling sound disappears complitely! but the wining sound is there then. It dosn't sound bad, only when it's cold it's very destinct.

I was just wondering how much one should be able to hear that wining sound. The sound dosn't bother me at all, and i simply hate the ratteling sound. I just don't want to break anything in the engine...

And discovering this option to adjust the balancer is the best thing that happened to me since the invention of beer and Denmark defeating Sweden in the last soccer game
