BBS01, BBS02, BBSHD controllers/motors maintenance

[Doran]

Does anybody on here have an idea of the type of silicone and grease to use when doing maintenance on these controllers / motors.

I remember seeing a list of products somewhere online, but cannot remember where it was.

Thanks in advance for any help

I've gone with the Mobil 28. Seems good.

I recently read about "marine" wheel bearing grease. pretty much the same price as the regular synthetic automobile wheel bearing grease. The marine version has a few additivces to make it work better if it is occasionally immersed in water. This is because lake fishermen often back their truck down a "boat ramp" to put the boat and the boat trailer in the water to launch the boat. Doing that puts the trailer wheels into the lake water, so this product was developed.

Nothing wrong with the current "de facto" Mobil-28 recommendation, but...I want to experiment with synthetic marine wheel bearing grease next...

FROM THE ES WIKI


Bafang has advised the following greases are applied during assembly to Bafang units:-
Bearing grease - Unical Lithium grease No 2. This grease is applied to the thrust and needle bearings contained in the BB.
Plastic gear grease - Unical Aviation Synthetic Grease AG-11. A white lithium grease is used between the motor shaft and the nylon helical gear.
Metal gear grease (Black)- HCF Lubrications Technology Co Ltd's MG - 2A grease. This is situated on the large reduction gear and the small metal transfer gear. This should be periodically replaced, given grit can get into this area and grind on these gears.
Metal gear grease (white) - Unical Polybear Grease BLD 227B. From correspondence issued by Bafang, it is unclear where this lubricant is used.
Bafang have acknowledged that these greases are unlikely to be available locally and have advised to use Shimano substitutes where possible.

Me too. If you cannot find the M 28, there is list showing compatible alternatives out there somewhere.
