When it comes to installing the Shimano FC-3500 [paid link] crankset, cyclists often find themselves weighing the option of performing a DIY installation versus hiring a professional mechanic. Both approaches have their pros and cons, and the decision largely depends on your level [paid link] of experience, the tools you have on hand, and how much time you’re willing to invest in the process. In this article, we will explore both options, discussing the installation steps, required tools, and potential pitfalls of each approach to help you make an informed decision.
DIY Installation of the Shimano FC-3500 Crankset
Tools Required for DIY Installation:
- Shimano FC-3500 [paid link] crankset
- Crank puller
- Bottom bracket tool [paid link]
- Allen wrenches [paid link] (usually 5mm and 8mm)
- Torque wrench [paid link]
- Grease (preferably bike-specific)
- Chainring bolts (if replacing)
- Anti-seize compound (optional)
Installation Steps:
- Remove the Old Crankset
- Begin by removing the pedals using a pedal wrench [paid link]. Pedals can become tight, so apply a generous amount of force if necessary.
- Use the crank puller to remove the old crankset from the bike. This tool threads into the crank arm and then pushes the crank off the bottom bracket spindle.
- Prepare the Bottom Bracket

- Use the bottom bracket tool [paid link] to install the new bottom bracket into the bike frame. Ensure it is tightened securely, following the torque specifications recommended by Shimano.
- Install the FC-3500 Crankset
- Place the left crank arm onto the spindle and secure it using the recommended torque. Shimano cranks typically require a torque of around 35-50 Nm, so using a torque wrench [paid link] is crucial.
- Repeat the process for the right crank arm, ensuring both are evenly tightened.
- Attach the Chainrings and Pedals
- If you are installing new chainrings, bolt them onto the crank arms, ensuring they are aligned correctly.
- Once the crankset is installed, attach the pedals. Always remember that the left pedal is threaded in reverse. Tighten the pedals securely with a pedal wrench [paid link].
Pros of DIY Installation:
- Cost-effective: By installing the FC-3500 crankset yourself, you can save money on labor fees.

They will also check the bottom bracket installation to ensure there are no issues with its fit or function.
Pros of Professional Installation:
- Expertise and Experience: Professional mechanics are highly trained and experienced, ensuring the crankset is installed correctly the first time.

Which Option Is Right for You?
Choosing between DIY and professional installation depends on your individual needs and circumstances. If you have the necessary tools, experience, and confidence, installing the Shimano FC-3500 crankset yourself can be a rewarding and cost-effective option. However, if you’re unfamiliar with bike maintenance, don’t have the right tools, or simply prefer to avoid the risk of damaging your bike, professional installation might be the better choice.
For those who are new to bike maintenance, opting for professional help can ensure peace of mind, while experienced riders with the right tools may find DIY installation both satisfying and economical. Ultimately, both options will result in a properly installed Shimano FC-3500 crankset, but the approach you take will depend on your level [paid link] of expertise and your comfort with bike repairs.
