What tool to remove Bosch CX Chainring?

[SquireRides]

Hi eMTBers,
After a failed motor bearing on my Bosch CX (after ~1200 miles) Im being ultra careful about flushing out the grease down there. I never did jet wash, but I did use a hose and a lot of Muc Off regularly.
To avoid that happening again, I figure I should instead remove the mini-chainring and give it a good degrease and lube well away from the motor bearings.
I have a crank puller. What else do I need to get the chainring off?

There is a motor bearing replacement video in this forum that goes over this.

Great. I think I found the right part: Bosch Lock Ring Tool | Merlin Cycles

Icetoolz also do one for a lot less than the Bosch tool.

Top Tip for you . Get a plastic thin bag cut 2 longish strips and wrap them around the inside of the cranks .That way no water can get in . Works for me when washing the bike
