30 May Tech Tip Tuesday: How to repair the seals on your stabilization legs

Cleanliness is the most important operational property of hydraulic oil, because contamination can quickly destroy system components if it gets too severe. However, in the harsh working environments of the aggregate, mining and construction markets, some level of contamination is possible the longer equipment is out in the field. In the event of leg seal damage due to contamination, there is an easy process to repair the seals so you don’t need to replace stabilization legs.

All Power-Packer stabilization legs have seal repair kits, and they’re broken down by bore diameter:

Each bore size will have specific instructions for repairing the leg seals. In general, you will need to follow these steps:

1. Remove the legs from the system and bleed any residual pressure by cracking the check valves.
2. Remove the manifold and snap rings holding the cylinder, rod and pistons inside the barrel.
3. Remove the cylinder, rod and pistons from the barrel.
4. Replace all soft parts and lubricate with hydraulic oil or o-ring grease.
5. Assemble the legs in reverse order.
6. Reattach the legs.
7. Follow the fill and bleed procedure.
