Is there an adjustment screw underneath the black plastic allen wrench cap? Or is a all in one cap and screw combo? (Marshall Excelsior MEGR-253H High Capacity Excela-Flo Automatic Changeover Regulator)

Answer

Jan 07, 2019 - 07:54 AM

The Allen wrench cap is an access cap. The adjuster screw is another black piece with a screwdriver slot. The access cap must always be replaced and fully threaded in after adjustment, because the center post is a mechanical stop for the internal relief valve mechanism.
