Servicing the Shimano M360 derailleur.

[Slaphappygamer]

I’ve noticed that a lot of e-bikes come with this derailleur. I have one on my 2021 Ride1Up 700 Series bike. I’ve been thinking about servicing my derailleur, but had a hard time finding info. Except this manual.

Here is a great video of the derailleur being serviced and regreased. I really don’t know what he is saying, but I can see what he is doing.

Thought this might help someone else, since they seem to be a common derailleur system.

There's really nothing to periodically service on a mechanical rear derailleur unless you ride in mud and grit all the time. The guide wheels will wear (the ones in the picture look shot to me) and can be replaced, but I would check the hinge pin play and spring tension first. Replacing one part when the rest of the derailleur is worn out doesn't make sense.

At the price of that derailleur, I’d probably buy a whole new unit instead of buying just the one piece too. I just thought it was interesting to see how it all works and where the springs are. Since the manual doesn’t reveal their location, but does say to “wash and lubricate all moving parts.”

Some mornings I ride, are moist. Enough to wet my glasses and I have to stop to wipe them. When it’s cold enough, my shifting is poor. I think my lube is seizing up when the temp is about 45F and I’m sure the wind factor makes it colder. When it’s 52F or above, shifting is good.

Not sure if the grease in the derailleur would do the same.

I have taken my rear tire off many times and have dropped and replaced washers. I was missing 2mil on the drive side and shifting was horrid. I added the 2mil back and it was better.

I gave up on lubing them. they last so long it does not matter I have one with ovedr 16,000 miles it is also a deore xt. it works the same as when I was lubing it. Now the housing and cable are what need servicing. When shifting is getting glitchy tiem to replace it.

Your inner wire and housing are more likely to cause this. A good quality cable set that uses lined housings, coated cables, and cable ends usually makes a big difference.

Ahh, yes. I’ve got lots of wiring in my bike and it was choking the inner cable at where the cables and wires enter the frame. Also put some 3in1 oil in there. Shifting got better. I haven’t rode in cold weather yet so I don’t, yet, know if that was the issue.

What he said.
I've also found that clean is better than lube, especially with quality cables. I've used isopropyl alcohol with success... though that might not be as easy with cables running through the frame.

We use an Amsoil rust blaster spray to clean up old cables and housings, but it's a band aid. New ones are the right solution. I also use the plastic cable ends with them. They will help keep water and grit out of the housing.
