How to Clean and Reassemble a KINGrinder K2

Which KINGrinder K2 parts come apart for cleaning

The KINGrinder K2 uses an interior adjustment design shared with the K0, K1, K3 and K5, and KINGrinder's cleaning guide for interior-adjustment grinders calls this design the easiest of its models to take apart. The KINGrinder K2 parts removed for cleaning are:

• the receiver (catch cup)
• the spin dial
• the numerical dial
• the inner burr
• the spring
• the bearing cover

KINGrinder's cleaning steps for the K2 stop at these six parts, so the outer burr and main body stay assembled.

How to disassemble the KINGrinder K2

KINGrinder's interior-adjustment cleaning instructions take the K2 apart in three steps:

1. Remove the KINGrinder K2 receiver, then hold the handle so the burr shaft cannot rotate.
2. Rotate the spin dial anti-clockwise until it comes off, then remove the numerical dial and the inner burr.
3. Remove the spring and the bearing cover.

Lay the KINGrinder K2 parts out in removal order on a dry cloth, which makes the reverse sequence obvious when rebuilding.

Cleaning the KINGrinder K2 burrs and parts

KINGrinder's stated reason for stripping an interior-adjustment grinder like the K2 is to keep fines residue away. With the inner burr out, brush retained grounds and fines from the inner burr teeth, the exposed outer burr, the receiver and the spin dial threads. Check that no grounds sit on the K2 spring or bearing cover, since debris there can stop the stack from seating fully. For washing or liquid-cleaning guidance, follow the care section of the official KINGrinder K0/K1/K2 manual, which KINGrinder publishes as a PDF alongside a cleaning and disassembly video.

How to reassemble the KINGrinder K2

KINGrinder's reassembly instructions put the K2 back together in the reverse of disassembly:

1. Install the bearing cover, then the spring.
2. Install the inner burr, then the numerical dial.
3. Rotate the spin dial clockwise onto the shaft while holding the handle.
4. Refit the receiver.

KINGrinder also publishes a top bearing cover assembly video on its manual page; watch it if the K2 bearing cover does not sit flat.

Re-zeroing the KINGrinder K2 after reassembly

Unscrewing the KINGrinder K2 spin dial erases the previous grind setting, so a cleaned K2 needs a new zero. KINGrinder's grind-setting instructions define zero as the point where the spin dial, turned clockwise with the handle held, is tightened. From that zero, count clicks anti-clockwise back to your previous setting, and count clicks rather than reading the printed dial number, which KINGrinder says may not match the click count. The click reference and adjustment steps are in the KINGrinder K2 grind settings guide.

KINGrinder K2 cleaning and reassembly FAQ

How do I take apart a KINGrinder K2 for cleaning?

Remove the KINGrinder K2 receiver, hold the handle so the shaft cannot turn, then rotate the spin dial anti-clockwise to remove the spin dial, numerical dial and inner burr, and finally lift out the spring and bearing cover, following KINGrinder's interior-adjustment cleaning instructions.

What order do KINGrinder K2 parts go back in?

KINGrinder's instructions reassemble the K2 as bearing cover, then spring, then inner burr, then numerical dial, and finally the spin dial, which is turned clockwise to secure the stack.

Do I need tools to clean a KINGrinder K2?

KINGrinder's disassembly steps for the K2 use only the handle and the spin dial by hand, and no tools are listed for removing the receiver, spin dial, numerical dial, inner burr, spring or bearing cover.

Why is my KINGrinder K2 grind different after cleaning?

Removing the KINGrinder K2 spin dial undoes the grind setting, so the K2 must be re-zeroed and the clicks counted again from zero after reassembly.
