Swingarm bearings.
- Thread starter GTM®

If the castle nut was that loose, carefully inspect the bearings for damage. Without adequate pre-load they may have pounded causing damage to the race and bearing. Do you have the correct socket for the castle nut load adjuster? I don't remember what size the Allen is, I just use the one from my tool box that fits.
yes i have the castle nut socket. so once you have allen head that size you just turn shaft and pull out. the shaft does turn a a bit then stops
I found it 14mm
this thread has lots of great info. now, it's makes sense

How-To, check swingarm and linkage bearings on NTX
This is a combination of several recent threads all heading in the same direction: swingarm bearings for CARC bikes. This 2012 Stelvio NTX showed no signs of any bearing or linkage problems but as a preventative measure I decided to check anyway. The bike has about 6500 miles. Since the seat...

SEARCH still works.
Good. I was getting worried for a minute…

scott, there so much info on guzzitech! research is the key. concerned about hand tight castle nut. hopefully bearings are ok. I'm working in a carport which totally sux. stay tuned...SEARCH still works.

Assembled after Chianti break. Seriously, if the bearings weren't fully seated when torqued (it is only 10 Nm) it is possible the tension slacked off as the bearing seated over time from use.
yes, that's possible sir.
I agree with John. Given the time and mileage, it's just loosened up and nobody ever bothered to check it.
As is the case that I see all the time, many motorcycles never ever get routine maintenance nor see the top of a motorcycle lift other than the first time they we PDI'd before delivery.
So many people either don't understand that preventative maintenance and routine service and checking, prevents issues like this from going undiscovered.
I'll bet many of the members here, haven't taken their bike to a mechanic ever, or maybe once. In that case, I always like to ask people when the last end to end inspection was performed by them. Every winter, and summer too, I throw every single motorcycle of mine up on a lift, and I start at the front and work my way back, checking everything visually and by using my hands and fingers to touch, twist, poke and prod.
Just last week, I discovered a major frame bolt on my Piaggio scooter, up under the front axle, which had backed out halfway. Granted there were 2 bolts side by side, but 1 was completely loose. Not anymore. It was discovered, and rectified but if I didn't take the time to do these annual or twice a year inspections, then this might have ended up very badly. I avoid that at all costs.
Always remember, these are machines, and there are two schools of thought to machines. The first and the one I recommend it that machines like to be inspected, cleaned, lubricated, and checked over. It is always cheaper and more efficient to discover and intercept small problems before they manifest into real issues.
The second school of (non)thought is "maintenance by crisis" where people just hammer the hell out of their equipment until the time that it fails and only then, do they actually invest and time or money in repairs and service. I think that this philosophy is just utter lunacy.

If the 2 pinch bolts were tight and marks line up, it was set up that way in Italy. Yours might even have grease in it.
yes Steve that was first thought that the pinch bolts were not tight but they were
Every one I've worked on had very little grease in them. One had so little grease the bearings and races rusted. Apparently a cost cutting measure.
Clean & repack, do up the shock linkage. Everyone I have seen are dry dirt, don't loose any needle bearings, use a pan. Just make sure the inner seals are doing their job on swingarm pivot shaft.
will do Steve. does any body know the torque for the swingarm shaft?
It is in the manual in the downloads. Since you are a contributor you can download your manual. This time I'll help you out. Shaft is 60Nm, sleeved castle nut 10Nm.
