Universal joints

[activpop]

I've got one axis on the rear that doesn't articulate smoothly...did a search for this problem but didn't come up with much. Are there replacement parts available...like needle bearings and cup?

You would have to replace the entire cross (universal joint). There is a source in the Encyclopedia of Compatible Parts . . .

okay, here it is:

I assume this is related to your Moto Guzzi Stelvio 2012?

Here's the part from this site in French which I have not vetted yet; https://www.pieces-motoguzzi.com/moto-guzzi-motos/1200-MOTO-GUZZI-MOTORCYCLES/STELVIO/2012/Stelvio-8V-STD--NTX/Chassis/Transmission-cpl/415/70/1028002262/976

In any case, the part does not look like from a CARC, but if you have no luck anywhere else, including used spares, maybe I can check with them. They sell parts everywhere in the World, and I would think they can answer in English.

Yes, please clarify, @activpop, V11 or Stelvio?

I just got the Stelvio last week...no time to get into it yet. Who do you think I am?...Speedy Linguini?   I'll keep questions about that on the proper page.

I wonder if these V11 replacement universal joints are available still from that same supplier in Montreal. Or if they could be sourced elsewhere?

If you change them out, remember to retain the special, angled, reduced size Zerks fitted to your originals.

Those are the ones he says are in stock...CR15's. I sent him the pic for confirmation.

[activpop]

I found them in Romania...Montreal is still closer.

I did a lot of homework to find these. I tracked the manufacturer to Italy, but I could never find anyone in Italy who will ship to the U.S.- it seems to be an Italian tradition not to. 

The important thing here is to know that there are other units out there that have the correct measure on the box- but they are beyond junk. The only other vehicle I've ever found this size on are some Russian manufactured 4x4 ATV. I ordered some from China and when they came they looked like they were hand-hammered from poor iron ore by an upland Pakistani with two hard stones. I never found *any* confident source for the genuine Concordia units other than the Montreal distributor- I'm sure they can be had in Europe, but I couldn't find any path to order them simply- thus the phone call to Montreal.

Coming late to this conversation, but I just pulled out the swing arm on my V11 Nero Corso tonight for the first time since new (2005!).  There seems to be a bit of slop in the drive when I twist it one way and then reverse it.  Is this normal or how can you tell if they are done?  There is only 6k miles on the bike.  I didn't notice anything when riding the bike.  Contrary to what I was expecting there was plenty of grease on all parts from new.  

[Tomchri]

Since s arm is of, you are talking about front part of shaft connected to the tranny ?  Can you move,slide the shaft a bit on the splines, if, tighten the bolts.

Shoud be NO play in the ujoint.

Cheers Tom.

Tom is on the right track with his questions, I think.

The output shaft of the gearbox will have a bit of play relative to the input shaft of the gearbox, as will the final drive from the input shaft to the wheel drive. That is normal.

The drive shaft should sit tight on the bolted up splines, both the one out of the gearbox and the one into the final drive. The uni-joints have no play at all in them when they are good.

You need to have a specific look at all the steps along the way.

PS: at 6,000 miles I would be checking if it is all apart anyway, but not expecting any trouble. Assuming the bike hasn't been mistreated.

Anuvverps: there is also the sliding spline in the middle of the shaft that compensates for the difference in length as the suspension goes up and down. That will have a very small amount of play. If it didn't, it wouldn't slide.
