Front Sprocket noise Problem....

[Firefly]

Well--- I really hope it isn't what I think it is..... but here's what's going on:

Recently replaced rear wheel bearings--- had some noise before--- noise gone after replacement.

A few days later I installed new Gen 3 brake pads - had a few issues after initial install-- but all seems good now except for nasty "Brake Failure" code that needs to be cleared.....

While doing the brakes I decided to check the front sprocket as I didn't have time when I was doing the rear bearings. For the life of me I couldn't get it off --- basically seems 'fused' and 'rusted' to the shaft.

I installed a new sprocket bolt as per new new 81-89 ft/lb spec...... and suddenly have this 'clicking' sound-- very noticeable when coasting--- gets pretty loud and changes with the speed.

Now here's where it gets strange......

If I'm coasting in 4th or 5th gear the sound is not as pronounced as in 1st or 2nd......

And now it gets much stranger--- I removed the bolt and took a ride-- and the problem is basically non-existent with the bolt removed! If I really try to hear it I sorta can-- but it would not have been anything I would have noticed if that is as bad as it was.....

My first and worst thought is shaft and/or bearings......

I can roll it back and forth and hear it-- but not so much with the bolt removed.....


Any ideas ?

Hate to have this come up a week before we leave on vacation.....:gaah:

Okay-- I *might* have fixed it......

Sometimes it helps just writing down all the symptoms -- stepping back for a minute and then going back and looking at it again......

I noticed the end of the shaft and the sprocket were not quite even-- I mean darn close-- but not quite--- so perhaps when I was trying to remove the sprocket I got it to budge just a tiny bit-- enough that I could feel a very slight difference by sliding my finger across it.....

So I got my bearing/bushing punch set out and tapped the sprocket in until it was 'flusher' with the shaft-- torqued the bolt down and a quick parking lot test seems to sound okay.......

Will know more tomorrow--- but this would be a big relief if this fixes it! ray:

Did you replaced both the sprocket and bolt or just the bolt? opcorn:

 

[dltang]

I hope everything works out Dan, I hate those "strange" noises when you just know something isn't right.

 

[Firefly]

Just the bolt.... Don't ant to do sprocket until I do belt and rear hub--- hopefully not until 50k

You have magnet drain plugs ? If you are worried drop oil see how much metal is on magnet. When my bearings went there was more metal at oil change before failure. I saw metal before I heard noise so see if your oil is glittered. If there is a high volume of metal it won't last long in my experience. If no metal in oil I'd say you may be OK.

Disclaimer this is all from my personal experience, any deviation there as I cannot be held liable..:doorag::roflblack:

I suspect that your front sprocket is somewhat worn. Driving it further on the shaft would seat it in a fresh part of the splines, eliminating the movement that can cause the noise. It will not last long if this is the case. I would pull it, clean and inspect everything, take some measurements, and check for play after the rust is removed. Use some penetrant and a puller to remove the sprocket, if necessary.

Best of luck with getting it sorted out in time to make the trip to MV. :thumbup:

... Use some peetrant and a puller ...

:shocked: ewww.....

Better?

Better?

To late, Google indexing was faster....:roflblack:

Well, p*** on it then! :gaah:

I just had to line it all up I was late to the party but was still able to enjoy the show..

Like a episode of Scotty's bloopers thats some funny stuff folks:2thumbs:


Sorry McFly back to your dilemma:f_spider:

 

[Firefly]

The bolt was pretty hot when I removed it. After getting the surfaces level and reinstalling the bolt everything sounds and feels like before--- so I'm not messing with it until after the trip!

It will take some brute force to remove it for sure--- might let the dealer do that one----

Thanks for all the input--- for now I think I'm good to go!

Just need BUDS hookup to clear brake fault code now

 

[Firefly]

The brake failure code had magically disappeared----

I wish my blooper would! :roflblack:

brake failure code

i did have the same problem last week.it was the parking brake going over bumps. problem fixt it self,as a lot of codes have done over the years.
greetings Henk

brake failure message.

I had my brake sensor replaced because of intermittent brake failure code. Still did not fix the problem. What did? This Spyder Lovers forum which recommended checking the fluid level. I topped it off and "wala" code gone! You would of thought the dealership might of checked that as well but what do I know.

 

[Firefly]

Pretty sure my brake code was due to me letting some air get into the system--- -- so I bled the brakes and I think it just took it awhile to be happy and up to pressure....

Gen3 brakes are AWESOME !

Your theory is good---

Taking your theory a step further-- which is probably the case....

Having the sprocket 'out' just a bit on the shaft - the sprocket and shaft are in their previous 'locked together' position. Adding pressure via the bolt is pushing the sprocket against 'fresh' parts of the splines that the sprocket had previously not had much contact with--- thus causing the noise when the sprocket 'moves'.

By me 'punching' the sprocket further onto the shaft - the inside of it has finally 'gripped' and 'settled' into the 'new' area of the splines-- then tight bolt holds it in place and noise is gone.

So-- if I pull the sprocket I'm sure I will find that the sprocket splines are really worn-- or worse yet-- the shaft splines are too.....

So do you think the sprocket has 'spun' a bit on the shaft then? This would make sense considering the symptoms. Now I just have to hope the shaft is okay...... :shocked:

Need to get ahold of a better puller before I do anything else....

So there is where I'm at.
