The main hydraulic lift ram on Western snowplows allows the plow to be raised and lowered. Over time, the lift-ram packings (both o-rings and seals) may wear out and begin to fail. If you notice excessive leakage around the lift-ram packing nut even when it has been properly torqued, or if the ram fails to lift the plow or lifts very slowly, it is likely time to replace the lift-ram packings.
Things You’ll Need: Replacement o-ring and seal kit for your model plow, Hydraulic fluid (specific to your climate), Torque wrench, Feeler gauge set
- Coat the replacement packings with hydraulic fluid. Install the inner backing ring, by hand, on the packing set.
