Is this normal? Rear sprocket "wiggle"

rrgermanlv said:

I am just confused because my actual carrier has 6 nuts around it (not the flange ones) and the pictures I've seen of the OEM ones don't have those...

On a QC sprocket carrier set up you have the six nuts holding the sprocket cover to the QC carrier and a further six (sometimes 5) nuts holding the sprocket to the QC carrier. On an OEM set up because the sprocket houses the cush drive rubbers you only have the six bolts holding the cover to the sprocket. Hope thats clear!

I had him call me. It's getting worked out.

Yup!!! Thanks again man! I'll keep in touch once I get to take it apart

@rrgermanlv

Dude, no disrespect meant when I say this. Its for your well being. You sure you should be working on this bike ? You seem clueless on what we are talking about this entire post. This is your drive chain here. This is not low tire inflation, or a taillight bulb.

NOLA

He's doing ok. We go it figured out. Some funky carrier i have never seen. The flange shaft is too long. The spacer was in there and the nut was at 230nm just way too much difference between the flange and the carrier. Not compatible from a tolerance perspective. Its got an aftermarket chain as well. The entire drive needs to be serviced and checked. The place of purchase did the switch.

NOLA: No worries...! you are right, I had absolutely no clue about the subject or the name of the parts because I never had to deal with this in the past. But, with the help of Endodoc over the phone (and the feedback of all you guys) I was able to understand what was going on. Probably also because all these terms are new to me (english is not my main language)

I've always been a DIY kind of guy and know my limitations or when something is way too complicated for me to do. It will be a pretty straight forward fix. I just need to remove the flange and throw away that aftermarket carrier and sprocket and replace it with the OEM one.

Sometimes it is better to do these stuff yourself than having a "mechanic" do them for you (so far I've successfully replaced my reservoirs, exhaust, switched the suspension from F to P and back to P, rearsets, clutch slave cylinder, headlights, charcoal canister, servo motor and flap, gear selector sensor, brake pads, air filter, oil and oil filter + reset service light, and a few other things that I don't remember at the moment).

I believe that nobody will take such a good care of your own bike other than yourself. I am very anal about my bike, almost OCD and I will make sure everything is torque down to specs and working properly.

Cheers!

I hear you about undeserved reps which goes both ways. Quite often a good rep gets around because of the average person's inability for critical thinking (that works for bad reps too because people can be unfair when running their mouths or keyboards off). That goes double for LV! I used to live there and it was for 14 years; I don't regret leaving it!

Anyhow, the DIY I get but we get lazy, too busy, or just can't keep up. Sometimes the good techs screw up because they're human and can be distracted in a busy shop. But what you've got going here is beyond that. Just have to ask harder questions when looking for good service and figure out the response with emphasis on "why".

As mentioned before, that goes double for LV because there's too many people (or businesses with unscrupulous operators) there running around trying to see what they can get away with rather than focusing on doing a good job. Why? Because LV attracts those kind of people and it's not a bad place for starting over (quite a few California leftovers) but too many not understanding or caring why they're starting over as well as being a transient town.

When you do find a good business to deal with, stay with them but watch who comes and goes; the less turnover the better.

Glad you got it sorted

Please tell us what exactly was the brand name and model of the "funky" carrier that did not work.

Thanks

JT!!!! Sprocket model JTA761-38 (7075-T6) and carrier is JT too but model nowhere to be found

Anybody interested in buying it? It wiggles and won't fail on you! I've had it for about 5-6k miles! Lol

That's the problem with mechanics/work done these days its done half assed and to a cost. Not many businesses do it to a standard/properly/by the book.

My panigale's first paid service was done at a well known high reputation place. All they did was reset the light, still had factory rtv on drain plug/oil filter and the oil was as black as it gets with only 4k on the clock from service. And the thermostat housing was leaking

I do my own servicing

Dont you dare, lol.....some ...... will take it for free and try to "adapt" it to their bike.

Make it a ashtray or something.

Hahaha yea, I won't do that to anybody.. I was joking..... hmm ashtray! that's a good idea!

But, in all seriousness.. how bad is that JT brand? the conversion is about $130ish apparently.... mine obviously had a wiggle/play but maybe it was defective? I cleaned it just to see if I could find any flaws and that thing looks brand new

Which bike do you have 1199 or 1299 ?

I would take it back to where you got it fitted and make sure they put the correct carrier on. the carrier for the 1198 etc is different to the 1199 series

check this link, the carrier needs to be 770B model.

JT Sprockets: Catalogue

I doubt there is anything wrong or funky about it. More likely just the wrong part for your bike.

2013 1199 base / ABS, the carrier looks exactly like that one (on their website they have a picture of another one that has holes, but mine is exactly like the one you are showing)

I unbolted the carrier/sprocket nuts and also my OEM flange/cover crush drive nuts and put everything back to specs... problem persisted.


The flange/cover sits pretty much flush with the carrier and sprocket but as soon as I put them back thru the shaft something happens that causes the wiggle, even if I torque down the outer nut to 230nm. Something is not right but I just can't understand why. There's gotta be a part that's not compatible with my bike and its like 1-2 mm thicker? I dont know.. it's weird

Unless my crush drives are bad? I dont think so, they look ok to me

I guess I will find out today as soon as I get the OEM sprocket in the mail and install it... there should be NO play... I will update the post with the results

OEM sprocket installed and no more play... Everything torqued down to specs and chain cleaned, lubed and adjusted. Still need to clean the swing arm but I will do that after I go for a ride tomorrow, I am sure it will splash some chain lube.

Can't go for a ride yet to see if I feel any difference because I still need to wait 24hrs for the loctite to dry (cush driver thread/nut)

I found a new use for that conversion. "Wall art":


Thank you guys for all the replies and feedback..!

Sooooooooooooooooooo.......

Post #4 was correct then.

NOLA.

Negative. The flange and the sprocket carrier should be a tight fit regardless is there are any cush drive pins in the drive assembly at all. You are again comparing apples to oranges when you are talking about the factory integrated drive. The fact remains that there was way too much play in the integration of that funky aftermarket carrier and the stock flange. However Nola if you want to be right, then I am sure we are all good with it.

I would be more than happy to mock up both the factory drive and an aftermarket 3 piece so that you can get a grasp on the mechanics if that would help

If he completely removed those 6 12 point nut that sprocket right now would not have play in it. The cush drive pins are just that, drive pins..
