Had taken the cover off to grease it as advised on many other videos then couldn’t get cover back on! No panic ... but thanks to your clear instructions I got it back together again. Basically it was the clutch rings stopping cover fully slotting back ! Once I inserted them as you advised directly into cover and then a careful spin of crank arm slotted home easily. Thanks 🙏
I’ve used a monoject 412 syringe,buy them on amazon.Works great for getting in the hooks and crannies. Used the Mobil 28 grease,now my bike tires make more noise then the motor.
Too much grease. A 1/4 of what you used would do it. The 'noise' level... seems like it was the same - before and after. Wonder if there isn't something else causing it perhaps a bearing.
Jeff Mueller 10% decibel reduction despite the camera being further away before greasing. Not a huge difference (it was practically new after all) but still significant, just difficult to show on a video. I've got another video on my channel done by another electricbike.com forum member showing more dramatic noise reduction. His motor was more used though. He actually used even more grease than I did. Over a thousand miles later and it is still running nice and quiet :)
The loud noise means that the parts are rubbing and grinding... This process will extend the life of the motor. In some cases, the motor will last twize as long.
I've taken apart my BBSO2B. Cleaned Nylon gear, re greased with Mobil1 Synthetic (red). Wiped down the pinion and granny gear. Re greased with Mobil1 Synthetic. However, the original grease on all gears and the new Mobil 1 synthetic "spins-off" the parts fairly quickly/easily. I don't think this is a problem as it leaves a nice thin coat, but, hmmm...over time, could the lack of grease become an issue ?
O.K. this is a good video and forget all the complainers and comments aside from the whole point of this video. The only mistake I can see possibly is putting to much grease on in and around the clutch cause if you do this it may not be able to engage fully. By this i mean the metal prongs cannot expand fully cause to much grease is in the way and actually causing premature wear, thus not having enough bite. Just a thought and like your video thanks.
a grease gun or a squeeze tube of moly grease with lithium 2 works really well. This make s much cleaner application and it is applied much more uniformly.
My BBSHD makes less noise than that, and I have the Ludicrous controller(3k watt)!!!!! I see the LUNA scooter in the background, so I assume you got your BBSHD from them too, good....they are the best out there for Bafang products, and have GREAT staff and support. BUT, you really should look into swapping out that controller for the Ludicrous, and if you do, swap the nylon gear for the metal one. Additionally, using a thicker grease( I use red and tacky) can also make it a bit quieter.
That has ludicrous on it, though it may not look it as that was one of the first prototype controllers with original casing. It is important to note this was greased as a demonstration for other folks that need to do so, this particular motor was not noisy to begin with. The mic sounds a lot louder in an empty room with no load. But thank you for the feedback on Luna support, as the support manager I certainly appreciate it.
Possibly on the steel gear yes. Not sure I would use that on the nylon primary though. Mobil28 is basically the gold standard for grease used throughout the BBSHD internals so that's what I would recommend the most.
The majority of the noise that comes from these units is the large diameter bearing that is pressed into that outer casing that you took off. The large cog is pressed into the inner race of that large diameter bearing. It is the rumbliest piece of shit bearing and needs attention from the get go. You can easily pry without damaging the black cover of the bearing and from the outside and rinse out all the the old grease ( with solvent) and repack with grease and replace cover. Those two cogs do not need that much grease. Upon inspection, there was clear rust tarnish within the top and bottom race, the cage and balls were tarnished even though it was previously packed well with grease. I was contemplating whether to pack it with metal polish and run it by hand to quieten the rumble but didn't have enough solvent to flush that out. I ran it dry for 5 minutes by hand flushed with remaining solvent, plenty of swarf debris came out (tiny but gritty particles) then repacked with grease. A much smoother bearing now almost devoid of sound. The smaller crank bearing on that cover plate is behind the clutch is silent and is the acid test for sound comparison .
Would love to see a video if you happen to have one on doing that. Personally I have run the motor with the secondary reduction housing completely removed and it is not silent so I am a bit skeptical.
@@fuzzyfriendlydoggy Sadly I don't have a video or even a channel. However thinking on it might be interesting to give it ago as soon as another one comes in for work. I don't understand what your skeptical about. I'm only comparing the sound of the small diameter crank bearing against the large secondary drive cog bearing that surrounds it within the outer casing . The last one I worked on had the worst of any rumble that incidentally no bearing should ever make. It had done around 1k miles, no sign of water ingress, all very clean, with not much factory grease and I'd agree not enough either. Having hand cranked before dismantle there was no obvious resistance due to friction, but that bearing was as lumpy as a cobbled street. With noise along with. I was surprised at the ease of removing the rubber bearing seal, I used a feeler guage and just lifted the outer edge as I ran it round and it popped off. It was blatantly obvious there has been some contamination either before assembly or in the grease as I scraped off the grease on the cage and it was gritty between my fingertips. Some of it was a bit swarfy ( as in metal filings) other bits were spongy discolouration. After removing the grease, which took a while using an aerosol solvent to thin the grease out and constant spinning the large cog to agitate, draining, wiping, rinse and repeat etc etc etc. Dried then manually spun the bearing over white tissue and more fine particles, spun it until I couldn't see new stuff falling out then rinsed again with solvent and dried again. Although it had improved, it would have benefitted from polishing but didn't have enough solvent on hand to rinse and repeat. So repacked a replaced seal. The improvement on the sound once grease was in the bearing was quite remarkable but clearly wasn't perfect because it's not smooth as it should be.
I have combined superlube silicone grease with 0.1micron tungsten disulfide powder and ist's awesome, much more silent than Mobil 28, especially under load
@@geegee8625 i can't talk for red'n'tacky, but I now use modified xtreme heavy duty from Lucas. I add about 5-10%vol synthetic automatic transmission oil and a generous amount of 1.6micron PTFE and this grease cocktail does wonders to the gearbox. no displacement and excellent lubrication at high motor power. The motor sounds almost as silent full gas as in candle power mode. not so with generic greases
It’s like Jack Nicholson is doing the demonstration! I will check mine when fitting and put some on but not as much as that - i would look to replacing with a metal drive if/when worn.
I use a MolyGrease with lithium2 thickness (about like creamy peanut butter).. Molygrease won't deteriorate the plastic gears. Choose the correct grease.
The recommended grease is: BLACK 3% Moly grease with Lithium NGLI 2... About the consistency of Jiffy creamy peanut butter. Other greases, like the white, grey, purple, red can degrade parts.
Anyone have issues with HD noise like metalic sound? After regreasing the helical nylon and rotor gear, then main crank gear as shown, the noise went away but after two trail rides, the noise came back. Anyone experienced this?
x2mars possibly fine, everything is metal where the secondary is. If it is the part of the motor where the primary is you would want to be more careful since some greases can degrade the nylon gear. That said, I can't promise you'll get the same noise reduction and/or durability as with Mobil28, different greases have different viscosity, breakdown at different temps, etc.
It's unloaded and the camera is right next to motor, even closer than the initial test. Also that controller is one of the first prototype Ludicrous controllers so it's pumping out double the current of your average BBSHD, which shouldn't make a massive difference in sound but I can't imagine more power probably does add more noise. Even with the closer camera angle amplifying noise it still registered >10% decibel reduction, very decent reduction for a few minutes work on a new motor. Sure you can go further with doing the other side but it's significantly more time consuming. Doing this much is fine for most new motors and it is whisper quiet with a load. This guide is meant for newbies who just want to do something easy to improve noise, the link in the description covers a full overhaul including parts list and multiple teardown videos. electricbike.com/forum/forum/knowledge-base/motors-and-kits/bbshd/36670-bbshd-teardown-maintenance-and-greasing
We have two FS mtb with HD motors that we use to ride hills, both motors now have loud noises when we ride. Anyone have the same problems after 600 miles? Opened up both motors and did not find any obvious problems. Re-grease helical gear on rotor and the spur gears on crank drives with aircraft synthetic grease. Same noise problem after two rides.
I'll join the rest of the armchair quarterbacks.... I don't think grease generally solves problems. I've tried to grease bad bearings away and it never works! Only thing that helps is new bearings, with grease. Grease prevents damage it can't fix it once it happens.
Yes grease it but not like that people. Is that red rubber grease you used? If it was any quieter that's because you packed so much in its like a insulator but actually causing more resistance.
It's mobil28, well known for being the best grease for use on bbsxx. Use however much you want but mobil28 has been the gold standard for this use even back in the days of bbs01, then 02, now HD and probably even the new Ultra.
fuzzyfriendlydoggy that's why I asked buddy and didn't assume. Because it's red it did look like red rubber grease which is not suitable obviously. Hope your still enjoying the bike
Have you considered doing this video over? It's not all that helpful to stare at a bike sitting in front of the camera most of the time while virtually everything you do is out of frame. Might be better to get somebody to handle the camera for you.
I would love to if I had another low miles bbshd that was a bit noisier than usual, because you are right it absolutely could have been done better. It was shot at 3 in the morning on a cellphone with a fridge running in the background so you can't even really tell the significant sound improvement in the video. I have another video up which is a bit more professional but it doesn't go into as much detail ruclips.net/video/Rn1-pr415j4/видео.html
1st sound test is with the chain and tire moving .... This is a faulty comparison compared to a motor with no chain/load as at the end of the video. Use an Android/iPhone DB App for sound level accuracy. +1 Thumbs down.

I always fall asleep after 5 mins watching this video. Very useful. Thanks.
Thanks for the vid. Just fixd up my BBSHD and the noise has gone. I put the grease into a syringe, made it a bit easier to apply

Hey man...what brand/spec of front chain ring is that?
It is a 42T Luna Eclipse
You don,t grease the clutch so much later it sticks and does,nt work well !
Great work on video mate greetings from Spain
Can I use 100% silicone grease for nylon gear and clutch side gear instead of the Mobil why does everyone use the Mobil 28
Where did you get that chain ring?
It is from Luna Cycle
Mines untouched in 5000miles, still silent.
Thanks for the video. I’m wondering why the Chinese didn’t put some grease even if it was cheap.They never put a bit of on the gear.
What keeps grease off circuit board “green showing in 3 o’clock position “ or is it ok if it gets some on it
It is potted.
I have made 7000 km on my Bafang 500 48V no greas has been added , I am starting afraid about that

What were we supposed to do? I fell a sleep.
Hey man thanks for the video, I just have to say "put to much grease and you will and you will get it all over the pedal assist sensor" just saying.
