This guide is for cyclists looking to understand and maintain their Shimano FC-M371 crankset. It's ideal for those seeking a reliable 3x9 speed drivetrain component. The FC-M371 offers a wide range of chain case choices and a square taper bottom bracket fitment, but users should note the need for compatible bottom brackets and chainrings.

The Shimano FC-M371 requires a square taper bottom bracket. Ensure it's compatible with your frame's bottom bracket shell.
You'll need a bottom bracket tool, a crank puller (if removing the old crankset), a torque wrench, and possibly a chain whip and cassette lockring tool if you are replacing the bottom bracket and/or cassette.
Lubricate the chainrings and crank arms every 100-200 miles or more frequently if riding in wet or dirty conditions.
Use a degreaser and a brush or cloth to clean the crankset. Rinse with water and dry thoroughly. Avoid using high-pressure washers.
The product comes with a 12-month warranty from the date of purchase.
Yes, but ensure the replacement chainrings are compatible with your drivetrain (3x9 speed) and the bolt pattern of the FC-M371 crankset.
Replace chainrings when they show significant wear, such as hooked teeth or difficulty shifting. Using a chain checker is also helpful for making sure the wear on your chain isn't accelerating wear on your chainrings.
Check and tighten the crank arm bolts. If the issue persists, the bottom bracket might be worn and needs replacement.
Check the chainrings for wear. Ensure the chain is compatible with the crankset and cassette. Adjust the front derailleur. Check your chain for wear and replace it if necessary.
