This happened on my recent return Bike trip down to Setubal, nr Lisbon in Portugal.
Went with a friend, Danny, he was on his 2017 GS1200.
Plan was a two day ride down from St Malo (overnight Portsmouth-St Malo Ferry) down to Setubal, then the same on the way back, but taking the Caen-Portsmouth crossing.
In between, my Wife and youngest Daughter and I would tour round Central Portugal in a hire car for 10 days, they flew out and back.
Trip down went fine, just over 1400 miles of Autoroutes/Autovias/Autoestradas, with one night-stop in Haro, N. Spain.
The trip back wasn't so straightforward . . .
Left Setubal on the morning of Sat the 2nd, Caen-Portsmouth Ferry was booked for 2300 on the Sunday.
Followed the same route as on the way down.
Just south of Valladolid, in Simancas we pulled off the Autovia for fuel.
After filling up, I noticed the Rear Wheel was dripping with Oil, as was the R/H 30% of the Tread!!
Luckily the turn off for the Services was a 90° Junction, and not the usual nice fast R/H Loop!
Thought it must be the Main Seal in the Final Drive, so nothing I could do at the roadside.
Everything from the Hub outwards was soaked, I cleaned it up as best I could with Paper Towels, then we trundled off at a more sedate pace to see how bad it was.
My friend flagged me down after about 4km, the Tyre was wet again, pulled in at the next services.[You must be registered and logged in to see this image.]
Danny had to be back for work on Monday, and couldn't miss the Ferry, so he carried on.
I rang home to see if I was covered by my breakdown service (AA), I wasn't, but they gave me a number for a local recovery firm.
Booked a hotel for two nights in Valladolid while I waited for the Truck, which took me and the bike there.
Stuck it in their underground Car-Park, and started researching ways to get it sorted.
Couldn't believe it when I found there was a Guzzi dealer just 4km from the Hotel!
Sunday the next day, so had to wait until Monday to do anything.
Rode it to the Dealer Monday morning, their mechanic said it would be the Seal, and that they could probably get one for the next day.
Walked the 1km to a BMW Dealer, the Seal is the same on the earlier BMs with the R/H Final Drive, just a couple of mm thicker, but it does the job.
They said they could have one in the next day too.
That afternoon, I thought I may as well whip the Wheel off to see the damage, it was possible that the Main Bearing Cage had failed, and that would chew up the Seal, causing the leak.
This is what I found, the Seal was the only part not
covered in Oil . . .[You must be registered and logged in to see this image.]
Turned out to be the Boot on the top.
It's a double-skinned design, the inner part keeps the Oil in, the outer part that you can see just tidies up the look.[You must be registered and logged in to see this image.]HUGE
relief, as it meant the Bearing was also OK.
It also meant I could stop thinking about renting a Van to get it home, or paying to get it recovered home, and flying back, or nursing it up to Santander/Bilbao and taking the Ferry, or any of the other expensive scenarios I was contemplating.
Easy enough fix, I picked up a universal CV Boot Kit, cut it to size, and Wire-locked it on.[You must be registered and logged in to see this image.]
Got some Oil from the Guzzi Dealer, and cancelled the Seal order (still picked up the BMW one though, might as well have a spare).
Took it out for 20 miles or so, all good.
I'd originally booked the hotel for two nights, then extended it by two more, so I stayed the full four days.
The weather didn't look great on the Tues anyway, so I left Weds morning.
Decided to take it easy (well I am retired now), didn't have any particular day to be back for, so decided to go see friends in France on the way back.
Stopped over in Pau Weds night, then at my friend's Thurs/Fri.
Booked the Ferry for Sat night at 2300, so had the whole day to get there.
Boot held up fine, dry as a Nun's chuff still.
Will probably leave it as-is for now, no real need to change it.
I have a spare Final Drive Unit, I'm going to modify the upper part where the Boot clamps on, so it's a larger diameter.
That will mean I can get rid of one section of the CV Boot, so it's not so squished up.[You must be registered and logged in to see this image.]
