Replacing the Riser Seal on a Hunter rotor

I-20 with Poly PipeSTEP TWO

Place the base of the riser on a solid surface and grip the spring and riser body firmly. With the other hand, snap off the body cap—with your palm on top of the logo cap, pull up with your fingers.


While still gripping the spring and body, remove the rubber seal.

When you remove the seal, the spring's tension will be released. Remove the plastic spring and plastic springseat (if it was not pushed off by the spring).


Now that the old seal is removed, the new seals and plastic spring seat can slide over the top of the rotor's turret and onto the riser. Be sure to install the spring seat prior to the riser seal. After the new components are installed you can then reinstall the rotors body cap.
