A spring compressing tool including a plate having three spaced holes therein. A center hole is provided to allow access to the locking nut of the caster assembly and two other holes in the plate are in alignment with two already available holes in the caster flange. Two elongated threaded studs extend through the aligned holes in the plate and flange elements with nuts engaging the threaded portions above the plate and below the flange holding the spring compressed and the outer and inner cylinders in a fixed relative position while the locking nut of the caster is removed. Loosening of the nuts on the elongated studs allows the outer cylinder to move upward causing the pressure on the caster spring to be relived gradually until the spring is fully expanded and can be safely removed. The spring is replaced in the caster assembly by reversing the procedure outlined.
