guzzi323 Posted August 3, 2016 Share Posted August 3, 2016 This sounds quite similar to my transmission failure from a few years back. I hope yours is a less troublesome repair. johnk Very interesting read johnk. how about an update? what is your conclusion after a few years? I will have a very close look at my shafts after reading that. Everything seems fine now but I've been riding a lot less the past four years I think I've only put another 15K on it since then.

Bjorn Posted August 12, 2016 Author Share Posted August 12, 2016 we just came back from surgery. This is what we found: getting the box of was easy peasy after the last encounter with the thing haha. we first opened the inspection plate since that was the easiest to do. In that compartment of the box we only found 3 pieces of the bearing cage. So we opened her up further. We found a sh*t load of metal and alu parts in there. Most of the roller balls had left the bearing a broke out a piece of the casting. We have no clue how this happened but I find it very ''telling'' that a almost identical failure mode had been observed by a fellow owner posting his findings some years ago. Here a pic from that topic which as been mentioned here as well (thanks for that!) As for now.... the main guzzi dealer in the Netherlands is closed but we think our best option is a new gearbox....

Scud Posted August 12, 2016 Share Posted August 12, 2016 I have a spare gearbox, but it's with me in California. Sending PM in case a used one is a viable option for you. Link to comment Share on other sites More sharing options...

Kiwi_Roy Posted August 15, 2016 Share Posted August 15, 2016 Was it the plastic bearing cage? Sent from my shoe phone! Link to comment Share on other sites More sharing options...
guzzi323 Posted August 16, 2016 Share Posted August 16, 2016 Have you check your driveshaft yoke alignment yet? Mine was off and I had to have one yoke rewelded on at a shop so they would align properly. Link to comment Share on other sites More sharing options...
Lucky Phil Posted August 17, 2016 Share Posted August 17, 2016 Was it the plastic bearing cage? Sent from my shoe phone! The photo shows the destroyed bearing with a metal cage. Ciao Link to comment Share on other sites More sharing options...
Bjorn Posted September 15, 2016 Author Share Posted September 15, 2016 Worked out a deal with Scud (thanks for that!) and the gearbox has arrived savely. For the peace of mind we will have the bearing that failed on the old box replaced for the new one. We also noticed oil in the clutch bell housing. We suspect its the rear crank seal, this will need to be replaced as well. Since both require some special tools we will take it to the dealer. Not much to recognise as a V11 anymore Link to comment Share on other sites More sharing options...
docc Posted September 15, 2016 Share Posted September 15, 2016 We also noticed oil in the clutch bell housing. We suspect its the rear crank seal, this will need to be replaced as well. Pete Roper has reminded us that there are several sources of oil leaks at the rear of the engine. Worth reading his comments (as always): http://www.v11lemans.com/forums/index.php?showtopic=3751&p=35372 Link to comment Share on other sites More sharing options...
Scud Posted September 15, 2016 Share Posted September 15, 2016 Agreed - I recently suspected my main seal was leaking, but it miraculously stopped leaking when I put the clamp on the breather hose. If there is even a small crack in your breather hose, oil will work its way into the clutch housing area - and out the tiny weephole between engine and transmission cases. Glad the tranny arrived safely. Remember - it's from a 2002, which is the year that some had issues with Pawl boss/spring. Since it's out, it's probably a good idea to take of the shift pre-selector, replace the springs, and do the shift-improvement polishing. Link to comment Share on other sites More sharing options...
Bjorn Posted September 16, 2016 Author Share Posted September 16, 2016 We will look into the oil leaking bit! I have inspected to hose before. Looks fine on the outside. We have aready replaced 3 springs in the gearbox hehe . But thanks for the heads up! Link to comment Share on other sites More sharing options...
Bjorn Posted October 11, 2016 Author Share Posted October 11, 2016 Progress is slow but steady The gearbox has been rebuild by the Guzzi shop and is in working order again. During the search for the oil leak comming from the rear of the engine, the mechanice discoverd that the clutch was f*cked up. Somehow the rivets of one of the frictionplates had failed. I would not be suppised if this happed during the lock up of the gearbox. Anyway the clutch was fixed and the rear crank seal was leaking and was replaced as well. All in all enough euro's where spend on getting the bike back onto the road. My brother also modified the shifter mechanism according to the topic here on the V11 forum, and he is very happy how it turned out! He told me it makes a big difference. O and i also want to share these pics below. These are some pics from our old gearbox. What supprises us is the amount of corrosion! The bike is around 13 years old and we own the bike for about 4 years now. We have always stored it in a garage. However for 1 year this was a very very humid one. We dont know if the corrosion has always been there or occured during the last years. But this was not what we expected to find in a ''oily gearbox''. Even though its splash lubricated. anyway.... hope to stay out of the ''technical topics'' for a while 3 Link to comment Share on other sites More sharing options...
Galletto27 Posted April 7, 2020 Share Posted April 7, 2020 Hi all I've just recently bought a v11 cafe sport 2004 21000 miles. The gearbox isn't quite right. Most times it fine but occasionally if you stop suddenly and have to change down rapidly say from 4th or 5th to 1st gear the gear lever can jam in the pressed down position. I have to stop the engine and rock it a bit to free it up and it's fine again. Any ideas? Thanks peter Link to comment Share on other sites More sharing options...

Thanks peter Pull the selector cover off and do the shift enhancement procedure listed in the How to section and replace the shifter spring. Most motorcycle gearboxes struggle with what you have described though. They need to be rotating for shifting to work effectively. Ciao Link to comment Share on other sites More sharing options...
