In the repair process of the EDITION 700 gearbox, it is often necessary to replace the piston seal. When replacing the direct gear piston seal, the shaft spring retaining ring on it must be removed before the piston can be taken out for replacement. For the seal, since the piston return spring 3 presses the retaining ring 5 through the spring seat 4 (as shown in Figure 3), it cannot be taken out directly. It is necessary to press down the spring seat before taking out the retaining ring. Without special tools, it is not easy to remove the retaining ring. At present, it is a time-consuming, labor-intensive and unsafe job that requires multiple people to use a screwdriver and a prying board to forcefully squeeze and pry to remove the retaining ring.
