As you all can see by the looks of the back end of this Griso it spent some time underwater. South Florida sandy, brackish water no less. This goes out to all carc Guzzi bikes but especially the Stelvio. The Stelvio being Guzzi attempt to tap the adventure bike market. Apparently all the swingarm designs are identical from the bearing sizing to drive shaft length, sealing engineering and torque specs. There were some final drive issues prompting recall on some Breva models I believe. We have all been warned of checking the 2 sets of taper bearings and shock linkage needle bearings lubrication due to shortcomings upon a lot of carc swingarm assemblies/ installs at Mandello plant. The Griso in photo required a complete rebuild. It was done. But for awareness purposes let's stick with the swingarm and carc damage specifically.
If all who are reading this at this point opened up and removed carc you may of have not noticed that the swing arm itself is not a sealed unit the gear shift side and drive side itself are hollow and will allow water to enter inside of swingarm and travel over into the drivetrain side of swingarm if submerged. And upon water entering this area corrosion will attack driveshaft, output transmission splines, and final drive input splines. This is as one is assuming area was all sealed from contamination or water intrusion and was fine and dandy.
The carc oil was changed multiple times due to water intrusion as the ole trusty breather turned snorkel design allowed water entry. This bike had a lot of other work being done and parts replaced elsewhere obviously due to bikes partial submersion. With the bearings glanced over for prior grease and proper torque of nut/ spindle that put the swingarm project on the completed side. (Just lazy not to check the splines) There wasn't any signs or symptoms of anything wrong with carc or drive line system at all for about 5,000 trouble free miles of riding after rebuild. Alas,I started notice some slop rattle on light deaccel. Felt it on right foot peg occasionally. But beyond the silent block replacement slop I went through many miles ago and then replaced. Nope something is wrong Internal swingarm or tranny.
After pulling brake and disconnecting speedo, carc final came off spewing about 1 or 2 oz of liquid corrosion water on my floor. Followed by removing entire swingarm from bike. Almost all was corrosion killed. All except the output splines on the tranny. Highlighted in silver Molycote M-77. Replaced driveshaft, final drive, boots and all Oiteker clamps. Had to split case on carc and used a Breva final drive, in which I replaced with high end FAG bearings on both sides of drive. It's a job switching final drives out of the housings. But it can be done. Over 15,000 miles on new drivetrain and 2 trips to Asheville North Carolina. Tested and approved at this point.
Attention riders of the carc machines, whatever your situation, if your bike goes under at the footrest level (these things happen). Do yourself a favor and check for water intrusion into swingarm. Some have drilled a small drain hole just in front of final drive seal. Not I, but that's me. Catch it early and save yourself ALOT of cheddar, cash, coin, and time. Or even worse, wheel lock or slippage. But mostly be aware. These bikes are tanks and we love em. But even tanks can die from water intrusion.
