Hello Quan, thanks for reaching out. It sounds like you have one of the ST-400 Valcrum Threaded Grease Caps like part # VA63JR. If so, to add grease to this you pop out the light grey center plug to reveal the grease zerk underneath.

Hey Quan, did popping out the center plug to reach the grease zerk work for adding grease to your ST-400 cap? Knowing how that went could help others trying to switch from oil to grease caps.
