Oh hi,
As discussed in another thread I mentioned I would inspect my motor. The bike I bought was a demo bike with 250 miles on it. It was clear that it was demo'd well as it had mud in all it's crevasses. I now have about 600 miles, and after reading about the various hardcore rides some people have but the motor through I thought I better check mine.
First problem was my Crank removal tool was not the exact fit, it seems Park Tool CCP-44 is, can anyone can confirm that? I made a temp tool but would prefer the proper tool.
On the sprocket set we can see corrosion on the nut that hold the pedal arm on the crank.
Also we can see some corrosion on the inside of the crank axle, the following picture is from the right side looking thru the axle. Note the splines on the right side have grease, I noticed no grease on the splines on the sprocket side
Here is the left side case show some water spots
I see no serviceable items. Not sure what would have happened if I removed the lock rings on the axle. Hopefully the axle slides out and one could easily replace the bearings...does anybody know?
One surprising thing to me was how small this motor is, the plastic covering makes it look a lot larger. I cleaned it up the moter, ran a oil rag through axle, lubed the splines and stuck it back together. BTW those water spots are no big deal and common on AL, incase that worries anyone. I just sprayed it with dry lubricant as a protector.
Here is a picture of the 15t sprocket, which seems fine.
Must say it is thin, the black is a coating and you can see it on each tooth...anyone know why?
A side note, my rear brakes made a different sound on the last ride...well they wore down to the retainer clip. Didn't seem to damage the rotor and I put on new pads both front and back. (but only lasting 600 miles is surprise, the front actually had lots of life...I am afraid of washing out the front so I tend to use the rear brake more)
Finally the motor appears quite water tight, my concern would be bearing seals if exposing the motor to a lot of water...same as any other bike.
Has anyone seen a video of bearing replacement?
Also I bought the special cog tool to get the sprocket off. You could remove it by other means, but you might damage it.
(I posting now, may come back and edit grammar)

Actually they have a cog tool, but it is not clear if it is the same size. I will investigate that more.
