Do you have a bead breaker that breaks the bead on single piece, two piece and 3 piece wheel assemblies? Does the tool push or pop off the wheel under hydraulic pressure? Are the replaceable teeth or the bead breaking foot bending or breaking under hydraulic pressure? This could be caused by the bead breaker running out of sequence. In other words the bead breaker foot will start to extend before you reach the maximum clamping pressure needed to properly clamp to the wheel. The problem can be taken care of by replacing the spring and ball in the sequence valve. Here are instructions for the installation of the ball and spring in the sequence valve.
1. Remove the sequence valve body, located at the base of the main body behind the bead breaker foot, with a ¾” wrench. Part #21599
2. Remove spring and ball and discard. Part #16724 (spring) #10375 (ball).
3. Clean out port area and ball seat area with parts cleaner and blow dry with air gun.
4. Inspect ball seat area for possible damage. If there is damage to the ball seat it can be repaired with a seat honing tool. If a honing tool is not available then the main body of the bead breaker will need to be replaced (very rare). Part #64250
5. Drop in a new steel ball. Then using a brass punch, seat the ball with a slight tap with a hammer.
6. Drop in new spring. Part# 16724
7. Replace copper washer, if necessary. Part# 10261
8. Tighten down valve body.
