Service tips for ESCO 10301 to 10305 10 ton, 10,000 psi. Hydraulic Cylinders
Here are a few tips that will help prolong the life of your 10 ton, 10,000 psi., Hydraulic cylinder:
· Use coupler dust covers when not in use. This will help minimize internal contamination. Dip couplers and diesel fuel or kerosene and wipe off with a clean towel daily.
· Make sure that the recommended hydraulic fluid in your air hydraulic pump is clean. Check the fluid periodically and change the fluid as needed. This will help the seals in the cylinder assembly last longer. This will also prevent contamination build up in your hydraulic lines. Any AW32 hydraulic oil is recommended. Transmission fluid is not recommended, it may damages seals.
· Push or lift from or against a flat surface. Hydraulic pressure that is applied and not centered against the lifting or pushing surface becomes unstable and is called a point load. This prevents a point load situation, which can cause damage to the cylinder assembly or potential injury to the tire technician.
· Do not exceed more than 80% of the maximum stroke available when extending the piston rod of the cylinder assembly. When the piston rod reaches maximum stroke, the brass rod bearing (located on the base of the piston rod) will bottom out on the stop ring(threaded at the top of the cylinder body). Constant hydraulic pressure against the stop ring can cause it to partially blow out. If the job requires that you exceed 80% of the maximum stroke, it is recommended that you use a ram with a stroke that is the next size up. ESCO has a full line of 10 ton rams ranging from 2”, 4”, 6”, 8” and 10” strokes.
