Bafang BBS0x Installation Advice?

[jtrops]

I am currently watiing for a BBS02 to arrive. As a bike mechanic the basic installation is very straightforward, and simple. Based on the recent thread about the bottom bracket bearings I have concluded that packing the BB shell with grease would probably be a good thing. Are there any other more advanced installation tips that would reduce problems down the road?

I imaging that as people chime in with tips I will update this first post so that there is a single itemized list of preventative measures. So:

1. Pack BB Shell with grease. This is the Bafang's BB shell, not the one on the bike frame.
2.Thread lock on bottom bracket lock ring threads (again , the smaller BB), removable such as Loctite blue 242
3. Check frame for clearance with large chainwheels before installation.
4.

My BB nut came loose a few times. I would put a little threadlocker, just a little bit. Not sure what size chainring you got, but check for clearance before you tighten everything down. My 52t didn't fit and scraped up the frame when I was testing it.
Personally, I'm not sure packing grease into the BB shell is going to do much

That's a good point about the chainring size since the chainline is essentially in the middle ring position for a standard triple crankset. I would guess that there are a lot of frames that would top out around 48t.

Since the bearings inside the BB are open, and it apears that they have very little, if any, grease from the factory, it seems that packing the shell with grease would get grease into the bearings which would probably help give a bit more life to the bearings, and races.

Do you think boiled linseed oil would be a strong enough thread lock, or should i use blue loctite?

I would recommend you to use Loctite 243 (blue). Loctite has over a hundred different thread locking chemistry. Some products are designed to lock threads permant, and others are intended for could be reopened. Loctite 243 is intermediate, and oil resistant. I use Loctite 243 on all bolts and nuts that have to do with the safety.. For example screws on brake discs, calipers and everything that has to do with the safety.. Use only one drop of Loctite.

If you have problems to opening a screw or a nut where it has been used "Loctite strong", I would recommend to heat the screw or nut with a hot air gun, or a gas burner. Take care not to damage other components with an open flame or heating.

Yes, I only keep the blue 242 in my shop, so I was vague. I wasn't aware that it is considered "medium". In my experience it is the lightest thread lock in the loctite range. To be fair the only other ones i have used are green "wick in - 290," and the red "permanent -270." The green runs like water, but it sets up really strong. Generally on bike the blue, removable, version is all thats necessary. I guess on ebikes there could be applications for other products.

Hello Karius,
Bruker dere Loctite på tennene slik at Baktus ikke kan ta dem?
