Hydraulic Piston Pusher / 185 mm / Yanmar EF453T / 5-25-117-05

Hydraulic piston pin , hydraulic lift piston rod with a length of 185 mm , a diameter of 38 mm and a diameter for the mounting pin of 7.85 mm for Japanese tractors and mini tractors Yanmar EF series and others.

The push rod , or the push rod of a tractor's hydraulic piston, is a component whose primary function is to transfer longitudinal load, pushing out a piston housed in a cylindrical body. The push rod is mounted on a pin on one side, while the other, rounded part, freely engages the jack's piston socket. This piston, when activated by a lever movement, performs a sliding motion, generating the appropriate fluid pressure and thus lifting the jack. The jack piston returns to its original or preset position (after previously moving the jack lever) under its own weight or the weight of the machine mounted on the jack, and in simpler designs under the influence of previously generated hydraulic fluid pressure (some hydraulic jacks use return springs).
