Thank you for using our bearings. As you probably noticed, these are genuine bearings direct from Brose the motor manufacturer. You may also have noticed that the two outer crankshaft bearings are specifically designed as "anti-creep" bearings. They use the specially shaped outer seal, to stop them rotating in the case and wearing the motor housing (This damage happens, incredibly fast too!) I noticed your recommended bearings do not have this important addition. I won't mention any of the other issues, except for the bonding (gluing) of the large pulley bearing (PLB20124). As this is a magnesium case, peening it with a pop riveter doesn't work and even from the factory, this particular bearing is bonded in with a high strength bearing fit. Without this, the bearing creeps out of the housing slightly and rubs on the belt cover causing a small misalignment of the belt pulleys, which snaps the belt and fill the motor with carbon and magnesium dust... Ask me how I know :)
Many thanks for the comment and thanks for your help when I spoke to you last month. I’ve got some loctite 638 here which I’ll use for the large pulley bearing.
Pulled the motor and that main large bearing didn’t take much force to get it out of the casing. All back together with the loctite. Everything inside is still spot on with no sign of belt wear or movement of other parts.
@@sce8arl Great news that all was still ok... Any chance of taking those bearing part numbers down, people will end up with the wrong bearings from some of those.
@@mateuszp374not too sure to be honest. Probably 3mm. The deeper the seal the further the roller bearing is offset which would result in the bearing not sitting in the centre of the axle load bearing area.
This is so frustrating, i know people who have 6000 miles on a motor with no faults then people with 600 miles motor failure 😮 my levo turbo 2022 model did 1000 miles and had motor replaced wasn't failed just stuck on sometimes very lightly! Just had the 2023 comp model fingers crossed 🤞🏻 feel afraid to ride it knowing this happens, but i have 2 years warranty so just guna thrash it for 2 years see what happens
For sure. I’m sure you’ll be good but if it does fail then at least you know it can be fixed. Was a pretty simple job to be honest so long as the electronic parts don’t fail. As with most electronic stuff it’s often a bin job. I would say that though as a mechanical engineer 😋. Fingers crossed.
@@sce8arl Wait and see. I think you have set the belt tension incorrectly. The correct setting is to set the belt to a specific torque value using a torque wrench. 🤷♂
@@ihabsglei apologies. That’s what I meant. The sensitivity of my torque wrench put way too much load on the belt hence why I stuck with the same clearance on disassembly.
@@sce8arl Damn 1700 miles and already cracked the case and needed a basic rebuild, you must thrash! Any tips on trying to keep bearings from getting wet. Great video Thank you!!!
@@Rambleon444I do tend to hammer the bike. Without the small seal that sits on the non drive side there’s no way to stop water getting in. I ride throughout the winter and take real good care of the bike, but water always finds a way in. Design fault of the motor. Hopefully it’ll last a lot longer now. Glad you liked it 🤙🏼
mais vous n'avez pas changé le débrayable de la couronne crantée, la seule façon de ne pas casser la bague noire c'est de faire à l'opposé une découpe en fenêtre de 8 mm le passage étant libre vous pouvez poussé facilement sans rien cassé

@@sce8arl Great, and if you need a casing when your lugs snap off, just give me a shout.
Thanks. That’s what I’m most worried about.

Great stuff! Very gung ho. Thanks also for listing those bearing numbers😊
No problem. Glad you enjoyed it
Great video! Thanks for the bearing list.
Was there a seal before the needle bearing in the engine originally? You install it at 18:45.
Not on the original. That’s why the water got in. Hopefully it’s fixed the problem.
@@sce8arl Do you know the thickness of this sealant, 3mm or 4mm?
@@mateuszp374not too sure to be honest. Probably 3mm. The deeper the seal the further the roller bearing is offset which would result in the bearing not sitting in the centre of the axle load bearing area.
Interested to see how long it lasts
75 miles in and still like butter 🧈

Great work. If the engine now runs longer than 100km without problems, then congratulations. 😋
75 miles in. Smooth as silk
@@sce8arl Wait and see. I think you have set the belt tension incorrectly. The correct setting is to set the belt to a specific torque value using a torque wrench. 🤷♂
@@ihabsgleithe suggested torque setting is 3Nm which was way to much hence why setting back to the original clearance.
@@sce8arl The correct value 0.2-0.3Nm. 🤔
@@ihabsglei apologies. That’s what I meant. The sensitivity of my torque wrench put way too much load on the belt hence why I stuck with the same clearance on disassembly.
How much miles do you have before rebuild the motor?
I’ve done around 1700 miles but without the water ingress it would’ve gone on way longer. The bearings not affected by the water were perfect.
@@sce8arl Damn 1700 miles and already cracked the case and needed a basic rebuild, you must thrash!

using a press is much more easier
For sure. I was too lazy to drag it out 😂

All went back together as it came apart with no damage. Running sweet as a nut
