Ducati 848 Engine - Rebuilding the stripped engine

[@LambChopRides]

Loved that! Looking forward to getting stuck in to my engine 😁

[@ducatibevel]

Cheers Adam... just the ticked on this wet miserable Sunday 🌧🌧😃

[@noallegiances8676]

Same here (western australia) mate, its been such a miserable day with a thunderstorm.

[@DesmoWerx]

Hi Rob, Glad it helped pass the British summertime for you 🤣🤣🤣

[@blowduke]

Wow you made that look easy great video ,may spur me on to do mine ..

[@DesmoWerx]

Go for it, here to offer advice if needed 😊

Hey desmowerx i just started my ducati 848 yesterday i was so happy thank you so much bro !! I took it apart all the way till i can see the transmission gears and put it back together . Somebody backed into it hard and it caused the crankcase to crack from where the kickstand attactches to the side of the motor. Bad design from ducati but i mean i guess they werent expecting you to get hit by a car lol.

[@DesmoWerx]

Wow, that's bad luck. The later cases are pretty strong as they are sand casted cases, so that must have been some hit.

[@239seth]

I have the same problem with my 848evo aswell they layed the bike over and cracked that weld under the crank case and stripped the bolts so I welded it back up but I need to re thread the bolts, thinking of buying a new crank case, but the bike made funny noise like a rod nock it was a cold morning I let the bike warm up and everything and boom out of no where it started to sound like that and when I put the bike in neutral it would die so I took it to the shop and hoping it won’t cost a arm and leg or else I’ll just fix what ever they say is wrong with the bike.

[@bryansautoandmotorcyclerepairs]

​@@239seth dang i didnt want to weld mine because practically all the weight of the bike goes on that kick stand. But here i am today rebuilding the bike again because of a valve that has a crack hopefully i can get it fixed

You are my teacher，👏👏

Thanks 👍

[@MrOsfaso]

Job well done thanks Can u help with a parts list to complete a full brake down and rebuild of the 848 engine

[@LeTessier916]

Hi Nelly. Just revisiting your awesome videos. Thanks. If you see this comment, any chance you can give us the dimensions of the open box you build the engine on. Looks really good. Cheers

[@DesmoWerx]

Hi Martin, the internal dimensions of the box are 275mm long x 210mm wide x 120mm deep. If you work to the internal dimensions it does not matter on the thickness of timber used. I used decking timber to make mine with a sheet of 5mm ply on the base.

[@LeTessier916]

@@DesmoWerx thank you very much 👍

[@nixdrone6621]

Hi , thanks for The Best video from you !!!!! What torque on cilinder head ?

[@ever-sd9iz]

Good job ！ Keep learning your skills😁

[@DesmoWerx]

Thanks! 😃

[@ever-sd9iz]

@@DesmoWerx 😁😁thans ,but 4 bolts on the golden cover,how many Newton meters？

[@ever-sd9iz]

I twisted it 9Nm，is it right？😥

[@jetninjamonkey]

when you torque the flywheel nut to 330nm, how did you keep the flywheel from spinning?

[@DesmoWerx]

There is a Ducati specific flywheel tool that I use, mine is not OEM but rather a copy made by another company.

[@kevinoneill9247]

Hey Nellie, Love your content. Ive done the gearshift springs on my MTS1200 2012 and just about to refit the Flywheel. The torque is 330nm. Can I ask what you used to hold the flywheel while tightening please? I have a gear jammer on order, but I spotted what looks like a punch being removed after torqueing and if there is a handy holding position to insert one to hold the flywheel, it might get me out of a bind here. Any help appreciated. Kev

[@markcooper3839]

again awesome video was hoping to see the setting of the gear hub/drum/selector. Do you have a link to another video you did? Thanks again

[@DesmoWerx]

Hi Mark, yes its in a few of my videos' check out kzbin.info/www/bejne/joCrk6qvl5ppZpI its near the start 😊

[@732duc3]

Great video! I’ve got a 12 848 race bike, I’m on the 3rd motor, the first 2 lost the crank bearings. It’s got 996 bearings in it currently. Is there anything else I can do to upgrade? Thank you!

[@DesmoWerx]

When you say upgrade, is that for power or reliability?

[@AndrewBoundy]

Amazing learning resource. When you're dealing with

[@DesmoWerx]

Hi Andrew, the difference in negligible as its microns thick once the cases are torqued down and it squeezes into a thin film. 😊

[@kris4362]

Nellie(Adam) another excellent presentation. Any more thoughts on the valve shim database calculator. 👍👍👍👍👍👍👍😎 ( Hokitika Sth Westland NZ)

[@DesmoWerx]

Thanks Kris, Still working through the sheet and formula's trying to work out how to protect the cells and calcs. 😊

[@kris4362]

@@DesmoWerx thanks for that. 👍👍👍👍😎

[@Desmo4268]

When you say preloading the crankshaft by 0.3mm am I right in thinking you basically shim it 0.3mm too big and then as the engine casings nip together it applies the right amount of force to the crank shaft? And also how do you know which side of the crank to shim? Do you just split the shims equally either side or is there a particular was to build the shim stack?

[@DesmoWerx]

HI Kyle, yes you add in 0.3mm of shims to get the preload on the crank bearings. If you are stripping the engine yourself you can measure the outgoing shims to see the bias of the shim loading between right and left (as sat on bike). Failing that I have done a video to show how to calculate the shims for your specific cases and bearings as fitted. kzbin.info/www/bejne/h6SxiXV7irCqq8U More often than not the left hand side of the case with the larger shim due to the case being offset more for the crank centerline. 😊

[@blitzerrrrrrr]

How do you determine what shim to use for the two transmission shafts if you are starting from nothing?

[@DesmoWerx]

Go with the smallest first as there should always be float so better to be loose and tighten it up by using the larger shims. Ducati only make two sizes of each of the different gearbox shims.

[@marklupton2064]

Love the videos, if my 888 let's go I know who I'll be nagging 😉👍

[@DesmoWerx]

Hi Mark, here to help if needed but lets hope you get many thousands of miles with no issues 👍😎

[@thediddly]

Beautiful workz! Watched 95% of your videos to date! Excellent job at explaining it all. Question: what are your inside dimensions for the timber engine stand? Cheers!

[@DesmoWerx]

Glad you enjoyed the video, will measure up the box and stick the measurements on this comment for you. 👍😊

[@ever-sd9iz]

When will the wires be installed? Waiting for you, my engine is also installed, I do it for the first time, I'm all learn from you

[@DesmoWerx]

Just waiting on the owner to send over the pulley wheel that's missing.

[@danielwoodhouse1870]

Hi mate. I noticed that you put sealant on the base gasket. Is that something that Ducati recommends or is that something you prefer to do? Just curious…

[@DesmoWerx]

HI Daniel, its needed to seal the lower cylinder area, its done from build as well. 😊

[@robevans916]

The factory head bolt tool is a C shape that places the wrench directly above the fastener so it doesn’t increase or decrease the leverage arm. With the tool you’re using, wouldn’t you have to alter the torque spec now that you’re increasing the leverage arm? It looks like you try to mitigate this by holding the wrench 90 degrees from the end of the tool, but the length of the tool should be accounted for, no?

[@DesmoWerx]

Hi Rob, holding the tool at 90 degrees negates the extra length, if I use it direct on I have to account for an 8% torque increase on my shorter torque wrench. I prefer using this tool over the c spanner.

[@ever-sd9iz]

3 times to 60, what tool is used to transfer? I have a torque wrench, but I can’t see what I’m using

[@DesmoWerx]

I use these sort of tools www.ebay.co.uk/itm/120796101958?hash=item1c20023d46:g:gWIAAOxyNDxRX-jm there are 3 different sizes 14, 15 and 16mm

[@ever-sd9iz]

@@DesmoWerx 😁,Thank you very much，😍😍

[@AnthonyKreutz]

is the torque spec for both of the Primary gear pair 190 Nm? Or is it just for the smaller one 190 Nm?

[@DesmoWerx]

The primary gear nut is secured @ 190nm, this is the small nut, the main primary gear is locked out whilst being tightened. There are two special tools available that make it easier.

[@AnthonyKreutz]

Am I right the nut which holds the Clutch basket is torqued to 120 Nm

[@592BerbiceBhai]

anyone knows where I can get a good used Ducati 848 evo vertical head to buy not too expensive?

[@andreapoti9305]

How much for this job?

[@DesmoWerx]

It would depend on what works are requested and parts needed.

[@Magicinstalls]

Doesn't the sealer take up any space…?

[@DesmoWerx]

Not that has any impact on the shaft clearances or preload.

[@Magicinstalls]

@@DesmoWerx of course it does. when you check it dry, the sealer adds at least .005. I would add that in

[@ever-sd9iz]

The plate inside the clutch, 5 Japanese bolts are 5Nm,not ten Nm ，Please verify😳,

[@DesmoWerx]

The clutch pressure plate bolts are 6Nm

[@ever-sd9iz]

Wish you happy every day

[@noallegiances8676]

Mate i like the idea of that wooden box as a cradle for the engine, im planning a rebuild soon on my 1098 ( dreaded crank bearing noise). If you dont mind share dimentions on the box please, cheers

[@noallegiances8676]

Oh and forgot to mention, Excellent video..

Thanks Taj, will measure the box later and stick measurements up. 😊
