Is this axle compatible with models other than the FH-M770?

No, this is a genuine Shimano part specifically designed for the FH-M770 model. Compatibility with other models is not guaranteed.

What tools are needed to install this axle?

Typically, you will need cone wrenches of appropriate sizes, a standard wrench for locknuts, and possibly a grease for the bearings.

What does 'item number 2 in the diagram' mean?

It refers to the specific position or part identification within the official Shimano exploded view diagram for the FH-M770 hub, indicating this is the main axle component.

Troubleshooting

Rear wheel feels loose or has play

Check and adjust the hub cone nuts. Ensure they are tightened appropriately against the bearings without causing binding.

Rear wheel does not spin freely

The hub cones may be overtightened, or there may be insufficient lubrication. Re-adjust the cones and ensure bearings are properly greased.

Axle appears damaged or corroded

Replace the hub axle with a new one. Inspect hub bearings and hub shell for any damage caused by the old axle.
