E61 Cam Lubrication for Sticky/Squeaky Brew Lever

If you find your E61 brew lever starting to feel rough, squeaky or sticking while rotating, follow along with this article to lubricate the cam and stop the squeak.

Also, keep in mind that a detergent backflush will make the brew lever action feel sticky, and pulling a few shots should make it feel smoother. If you follow our recommended 6 week backflushing schedule, cam lubrication should only be needed rarely.

Tools Needed:

  • Adjustable wrench
  • Flathead screwdriver
  • Food safe lubricant - we recommend Molykote Dow-111

1. Remove the E61 lever by taking out the flathead nut at the end of the lever.

4. If you're having a hard time reinstalling the cam, you can create an easier space by unthreading the bottom part of the e61. This will drop out the lower valve, making it much easier to install the cam first. After the cam is securely in place, you can reinstall the bottom part of the e61 with ease.
