Bafang Ultra gaskets, parts ..

[tomjasz]

when i did my bbshd there was a peas worth of grease from out of the factory, when regreased it transformed the motor.

What is the build date of the motor?

thanks!

In what way Haystacks???

Earlier versions had a bad rotor shaft and could be noisy from the lack of adequate lubricants. The chain ring gear was easily damaged with poor lubrication.

 

[Merle Nelson]

Ahh, thank you.

It became smoother, the resistance seemed to lessen too, can't comment on any noise as it wasn't noisy in the first place.

Not sure, I thought the first 4 digits were the manufacture date but they are 022F and the last 4 are 0115, but as this is one of Pauls motors i cant see it being a 15 batch sold last year.

Very interesting. I guess almost anything can be improved. Actually if just adding some of the right kind of grease does it in this case, that's pretty nice.

A few gaskets on the way for me.

Thank you.

I want to grease my Ultra and I don't have to pull the motor to do it, right ?

I believe … from video not experience, you have to remove the mount bolts to split the case as they seem to do double duty.

Asked this on the other gasket thread. Those who have split your case: Were you able to preserve the original gasket? How?

Ok thanks, I thought I just had to remove the outer cover.

 

[reed scott]

My plan is clean and re grease the motor. Here is a video of the process if it interests you.

Just don't drown your motor in grease like he did. He has since repented of that mistake.

I wondered about that. Especially in summer. Not much room for expansion.

 

[mxer]

Wow! he really did ram it with Greece!! Lol.

Great info that he has since repented of that Reed. Where did you get that from? I went to the video on youtube and there were no comments or "read more" notations.

Reminiscent of this screaming moron.

I don't know why they don't remove thier videos once they realize it's wrong.

Simon has been on our forum a few times. Can't remember if it was here or on youtube but he kinda laughed at himself for doing that and admitted it was dumb.

 

[Merle Nelson]

Okay Reed, great to know. I didn't see it on youtube proper and wanted to know if there was some que I am missing.

Gionnirocket he may not know he is wrong - yet.

Yeeeeeaaahhh I’m glad to hear that this video I uploaded years ago still helping lots of people out there!! The helical pinion gear unfortunately pushes the grease in the wrong direction making the gears run dry too quickly, I’ve greased myself maybe 300 BBS02 motors in 2 years packed a lot of extra grease before sending to customers and that alone fixed so many problems. =]

Sorry... But a moron patting himself on the back is proof of nothing.
I have opened up many different motors and gear sets of all different types and have never seen one packed that tight with grease.
You want to take the advice of someone who screams for attention like a two year old and goes against base industry standards... be my guest.

(1) Grease Lubrication
Grease lubrication is suitable for any gear system that is open or enclosed, so long as it runs at low speed. There are three major points regarding grease:
– Choosing a lubricant with suitable cone penetration.
A lubricant with good fluidity is especially effective in an enclosed system.
– Not suitable for use under high load and continuous operation.
The cooling effect of grease is not as good as lubricating oil. So it may become a problem with temperature rise under high load and continuous operating conditions.
– Proper quantity of grease
There must be sufficient grease to do the job. However, too much grease can be harmful, particularly in an enclosed system. Excess grease will cause agitation, viscous drag and result in power loss.

Lubrication of Gears is a page to explain how to lubricate gears. Lubrication is necessary to use the gears properly and avoid the damage of gears.

California eBike has the gaskets. Just not on the webpage yet.

Tom, you should know ... what is the technique for splitting one of these cases without damaging the gasket?
