Grease Shimano EP8

[Crave 05]

Hello everyone.

Not right now, but in the future, around 6,000 miles or 10,000 km, I'd like to open up my Shimano EP8 motor and grease it internally to extend its lifespan. I have the knowledge and experience to do it, but I'm unsure what type of grease to use. I'd like to know the brand and model. I've read that headset or bottom bracket grease isn't suitable, and my other question is how much grease to put on the sprocket teeth.

Thanks and regards.

It has been said that re-greasing the motor improves the range, so I am going to explain my findings.

In my case, I opened the E8000 motor with 7500Km (I have another motor with 7500Km), I checked that no water had ever entered, the bearings are fine and without rust and they spin smoothly, so I only re-greased:
* For plastic-metal gears I used Molikote PG-75.
* For the crankshaft needle bearings I used White Lithium grease
* For the seals of the bottom bracket, I used Motorex green grease that improves the sealing.

Once this was done, I closed the motor and then I tested it on a 40Km...
