Factory Tech Tip: How to Replace a Dirt Bike Clutch
Have you ever wondered how a factory mechanic would do a number of bike maintenance tasks? Well, wonder no longer. We have teamed up with Namura Technologies and former factory mechanic Scott Adkins of Pro SX MX Tech to show you exactly how the professional teams in the pits of Monster Energy Supercross and Lucas Oil Pro Motocross go about taking care of their rides.
Scotty's got credentials, too; he's worked as a mechanic on both series for 12 years and wrenched with some top talent like Nick Wey, Ryan Sipes, Jeremy Martin, and Christophe Pourcel, to name a few. So sit back, relax, and in this installment, you'll learn how to properly replace a clutch.
At a glance:
Remove the brake pedal spring.
Remove the clutch cover bolts and cover.
Remove the six bolts that hold the springs inside, then remove springs.
Remove the pressure plate.
Reach inside and then remove the old clutch plates.
Now with all the old plates removed you can start installing the new clutch.
Start with a fiber plate, then a steel. Always make sure the sharp edges are facing out. Once you get one fiber and one steel started you can then begin to reinstall the pins into place. Then you can continue replacing the plates. Fiber, then steel. Repeat until they're all in.
Next you'll put on the pressure plate.
Reinstall the bolts and springs that hold the pressure plate in. Once you get them all started you'll need to get out a torque wrench and tighten them down to manufacture spec. Check your owner's manual. When torquing them down use a crisscross pattern so they're all even.
Reinstall the cover. Again, use the torque wrench to tighten the cover bolts to manufacture spec.
Reinstall the brake pedal spring and always make sure to pump the brake. That's it!
