fantastic love watching you work , its a joy .. think thats a fine example of not having the right tools for the job with that case .. this wasn't a dell boy rebuild was it !!! 😂😂 many thanks sean 👍
Mate, great content as usual !! Thanks for sharing If the customer wants I have a spare set of cases for a 748 .. let me know if you’re (he’s) interested. Take care.
Do you think that damage was done using a gear from the gearbox to press out the bearing support ring ? Either that or done to improve the interference fit? Or just very poor work! 😱
Hi Chris, Just looks like poor workmanship, might of used a gear wheel but the gouges are all different sizes and there are punch marks in the hardened bearing carrier. Dodgy workmanship 😢
Hi Neil, quick question for you... I changed the belts and oil in a friend's W reg 748 yesterday..30k on clock.. upon removing the sump plug there was alot of metal filings on the magnet , but even more alarming was a sizable portion of a large washer... the sort of washer that would sit under a large securing nut, like would hold a clutch basket on for example....... clearly we are concerned but generally its running well...starting well hot or cold.... no smoke from exhaust and no excess noise bar a very worn clutch... of course it needs further investigation but have you ever seen similar in your experience? Some years ago i did an oil change in another friend's 916 and we extracted a piece of swarf.... but we spoke to the specialist who supplied the parts and he felt this wasn't uncommon on new engines..... but this looks different.....more like a failed component vs a piece of metal the engine has machined off itself while running in! Any thoughts gratefully recieved, I could email you a picture as I have one of the item. Regards Peter
It depends on the level of the work required and the condition of the engine. If its a standard build with no issues I can usually turn it around in about a day and a half.
Thank for the video mate :) Don't you think the impacts on the case are made on purpose to avoir this cylinder (metal around bearing inside the case) to turn. I know it can be an issue I had this on mine. The solution I used was to add mark on the cylinder to lock it better into the case, but I didn't damage the case the way it is on yours.
Hi Romain, that wold make sense if the builder had indent/witness marked the bearing holder but this has chunks of the cases just hammered through, I would rather use bearing lock if that were an issue than damage the cases! 😊
I'm not sure of this information is classified for any particular reason but how much should someone typically be paying for this sort of work? I am slowly collecting Ducati's and one or two of them are definitely in need of some love due to poor servicing by previous owners. I believe the main bearing has gone in my 916 and my 1198 is staring to knock. I guess you get what you pay for but if a good quality workshop is doing the honours is an hourly rate plus the parts going to cost more than you paid for the bike? I want all my engines "As New" standard as possible without having to re-mortgage the house.
Hi Aiden, it really comes down to what you want done and the condition of the engine that is being worked on. It can get silly if you tune the balls off the engine. The main cost is usually the parts involved.
I love engine strip downs you never know who’s been there before ..
Its like opening pandora's box 🤣
An engine rebuild is so much about trust in the mechanic/engineer. Great video.
Absolutely James and there are some cowboys out there!! 🤠
i could watch this all day :) Thx for the great content (again!)
Glad you enjoy it Fred 😎
Thank you for sharing all the small details on getting it disassembled!
No problem 👍
Best Ducati channel!!!!!
Thanks Frank 😊
Your knowledge on these ducks is amazing
Thanks, I do love a good Italian V twin engine!! 😍
Nellie, bloody hell, talk about cowboy bush mechanics (rhd main bearing). Keep up the good work mate. (Hokitika Sth Westland NZ) 👍👍👍👍👍👍😎
Hi Kris, yeah, it was a shock, shame when people do damage deliberately like that! 😒
Really enjoyed watching that wish I had the skills to strip my old 748 down an rebuild.
They are not that hard to work on once you get into them 😊
Satisfying video to watch! 👍🏼
Thanks 👍
Nice work, your videos hleped me with my engine rebuild last year.
Great to hear, that's why I started making the videos. 👍😎
Great video, shame someone’s attacked the casing like that.
Yep Ian, shocking that they also did not record that it had been done either.
Good video, as always. What a nasty surprise inside 😲
Thanks, and yes a nasty surprise, am really shocked someone sold the bike knowing that had been done! 😒
@DesmoWerx. Nice video again. Missing the music from the 748 race project 😉
🤣🤣🤣 I miss the music as well but it saves me time in editing!!! 👍😊
@@DesmoWerx is there a way you could help me with that sound file Nellie?
I only finding the wrong sound files.
fantastic love watching you work , its a joy .. think thats a fine example of not having the right tools for the job with that case .. this wasn't a dell boy rebuild was it !!! 😂😂 many thanks sean 👍
Thanks Sean 👍 whoever did the work needs to hide in their garage in shame! 😒
Thanks for teaching
It's my pleasure 😎
Awesome video as usual mate! Been looking forward to your next one 👍🏻
Thanks Tel, more coming soon, just trying to clear a back log of engines and suspension work!! 😊
Awesome video once again
How much to rebuild a 748 sps engine with some slight modifications ie slipper clutch etc
Many thanks adam
HI Adam, email me on the channel page with your number and we can chat through options 👍🙂
Mate, great content as usual !!
Thanks for sharing
If the customer wants I have a spare set of cases for a 748 .. let me know if you’re (he’s) interested.
Take care.
Thanks for the offer, he has a number of engines so is dropping off another for me to breakdown and make one good one.
Excuse me , i have a 749 biposto black, is it similar to the 748s or it chánges to much? Thank you, very helpfull watching how you work.
Hi Carlos, the 749 uses a Testastretta engine. I have deme some videos on a 749 engine build before onthe channel.
Someone has center punched the casing to stop the bearing outer spinning in the case. Thats my guess. :)
Yep, not great practice to see.
Do you think that damage was done using a gear from the gearbox to press out the bearing support ring ? Either that or done to improve the interference fit? Or just very poor work! 😱

Hi Peter, drop me an email with pictures and I can help. Its hard to talk through next steps in the comments section. 👍
@@DesmoWerx thanks Neil, where can I find your email? Regards Peter
Ducati mechanical engineering still amazes me.... may I ask, how much time does it take you to do a rebuild on a desmoquattro or testastretta?
It depends on the level of the work required and the condition of the engine. If its a standard build with no issues I can usually turn it around in about a day and a half.
@@DesmoWerx takes me a day more ..... ;) but I am slow
Thanks

The engine sound in the intro isn't L twin, right?
Hi Vojta, no its not, it was a generic motorcycle sound of a library. I must get to recording one of my own bikes. 😊
