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.

One of the most common problems a tire technician can face every day when using his air operated hydraulic pump is outside contamination of the air motor. This contamination, more often than not, will come directly from the air compressor. The compressor will build up sludge in the air tank over time, and if it is not drained on a daily basis this sludge will end up in the air motor of your air hydraulic pump. The sludge contamination will wear air motor seals prematurely and will directly affect the operating efficiency of the pump and will lead to an eventual failure.
What can be done to minimize this problem?
· Drain the air compressor daily.
· Install an in line “moisture block” or regulator lubricator filter in the air line from the air compressor.
· Change the filter in the air inlet of the pump periodically.
· Squirt a few drops of Marvel Mystery Oil into the air inlet side of the pump daily.
· Have the air motor serviced by a trained repair technician.
