The Fisher and Western 49014 is a genuine oil seal for your snowplow's hydraulic power pack, crucial for preventing fluid leaks from the motor shaft. This precision-engineered seal, measuring approximately 13/16" in diameter and 1/4" in height, is designed for older Fisher Minute Mount 1 and Western UniMount plows with either cable-operated or electric solenoid hydraulic systems. Replacing this vital component ensures optimal hydraulic pressure and extends the lifespan of your plow's hydraulic unit.
