After watching this video I decided to change the rear drive oil on my 2020 V85TT at about 6,300 miles. After doing that I had an issue with the rear drive leaking. I used a 60cc syringe to refill the drive with precisely the recommended capacity of 160cc. I rode the bike in the mid forties Fahrenheit and above for about a week with no problems. After riding about 60 miles in temperatures between 30 and 36 Fahrenheit I noticed the rear drive had thrown quite a bit of oil. I realized I had changed the drive oil cold. I ran the V85 for about 8 miles and then drained the oil to determine how much oil I had lost; I collected 160cc. I refilled it with 160cc and have had no problems since. My finding is that the rear drive capacity tolerance is very tight, and by not warming it up prior to draining it I must have left close to what I guessed is about 10cc of excess oil in, and then for some reason riding during the cold weather it burped the excess oil onto my rear wheel. I was concerned I may have damaged a seal by over-filling it, but after a couple thousand more miles with no issues I've ruled out any seal damage.

The manufacturers keep extending all the service intervals because they want to show people that maintenance is cheap. I keep my service intervals half of what they call for. Oil and filters are far cheaper than failed final drive, trans and engine.

The dark "tint" in the oil is a friction modifier that Guzzi uses from the factory. It's not a bad thing, but I would keep my oil in until the recommended service interval. If you want to change it, I'm sure that's fine too, after 6,065km, I am sure the final drive has been run-in. Thanks for elaborating on the 160cc update.

A little trick. Put tinfoil around the cat to guide the oil in a proper direction while draining. Scary story by the way 😳 Greetings from Denmark 🇩🇰

Great advice and very nice video, thank you! I believe Guzzi have actually changed the maintenance interval for the final drive oil to 30,000km now :-) No way I'd wait that long, this is definitely worth changing with every engine oil change.

Just had my break in service done and the Piaggio shop did the engine, transmission, and final drive gearbox. We had a conversation about it as I’ll be doing the next few services out on the road and he went by his shop manual and put 180cc in the gearbox…. 🤔 He seemed very knowledgeable… 🤷🏻‍♂️

Thanks for the movie. I had 175 ml of oil. The exchange went without problems. Regards

If you have a 1400cc Guzzi, (California, Custom or Eldorado) you’re not going to like what you need to do to change the gear case oil. You can drain it (DON’T) until you fully understand what you need to do to get to the oil filler port to fill it up with gear oil.

There were issues with not enough oil from the factory - so all Guzzi owners should check oil levels even in new bikes. My Guzzi had a major failure - one of the bolts which holds valve rocker (under the valve cover) came loose. Fortunatelly I noticed the sound, parked the bike, took off valve cover and fixed the issue on a side of the road. The bike is great but quality control very bad.

Great info from an actual user. Thanks for doing this video. How has the bike held up to regular use? Any mechanical issues or problems with the motor? I'm looking at getting a 2021 model and I'm curious about reliability. My current ride is a honda crf250l with adv mods for touring around my local area, Oregon USA. Can't wait to upgrade to a v85tt!

You can see light through that oil, it is not very dirty, it actually looks like it’s in good shape.

This is just like Range Rover They say the gearbox oil is for life What they really mean is it makes the servicing costs look less and once the car is out of warranty they dont give a shit !! Well done Range Rover for looking after your customers !!! I change any oil in any car or bike either every 12 months or every 6K It makes sense does it not ??????????? No oil is for life even if life is 15 years in any vehicle Why do they do this Range Rovers are not cheap Motorbikes these days are not cheap so WHY ?????????????

Thanks for video. Which oil does MG specify for the drive? Thx

For me your oil still looks nice. No need to change that.

I don't understand how you would put too much oil back in and over fill it? Isn't that fill plug, just like a level plug on most car and machine gearboxes etc? When you fill it up, it reaches the level plug and just pores out? How would you put 180 back in if it doesn't even fit? I hope this makes sense

It my be an overkill, but I change the final drive, and gear box oil every time I change the oil. It only takes a few minutes and the oils are pretty cheap.

Thanks for the video! What tightening torque do both screws have? (In Nm) Thank you!

Fresh oil is the cheapest mechanic you will ever pay for.

My owner manual says 180 ccl for the shaftdrive, somewhere I heard 160 ccl, what is right?

que tal ese motor es duradero mas que los enfriados por liquido o igual

Does the final drive drain have an O-ring, or a crush washer? If crush, do you have the specs or the part number?

My man……it is so easy!!! You refill oil until start leaking from the input hole!!!!

I thought I have heard that Moto Guzzi are now saying that the refill should only be 150ml?

Vi fate troppe segheria mentali, per la manutenzione devi seguire le istruzioni del manuale d'officina perché sono abbondantemente prudenziale, Ps l'olio diventa scuro dopo 1000 km

Does this guzzi have adjustable valves or shimming?

colour of oil doesn't matter. age, mileage and quality makes job. Fill final drive intil oil start drip from filling hole. First service with all oils change after teardown untill 1500km, second after 5000km or once a year. after first period engine oil once a year or max. 75% mileage from manual. gearbox and shaft - once per two changes engine oil. Or if U sink bike in water.

I’m coming to the conclusion watching your videos, that you just nitpick the hell out f everything, if you tip that cup of oil to the side,you can see it’s absolutely not very dirty, you can’t look at the way you are, hold it up tp light, you can see through it. Don’t understand your issue, you always fill the final drive up to the fill hole, all drives shaft bikes do that, and all rear ends in vehicles.

Just change once a year
