Engineered from high-tensile spring steel to maintain precise return tension and spool alignment under constant cyclic pressure. Ensures smooth, predictable valve response inside the machine’s primary hydraulic or transmission control block. Failure Symptoms: Sticky, sluggish, or unresponsive hydraulic control levers. Hydraulic spool failing to center properly, causing drift in cylinders or attachments. Loss of system pressure or erratic valve behavior due to a fatigued, sagged, or broken spring. Quick Installation Notes: Relieve all hydraulic system pressure completely before disassembling the valve group. Clean the valve bore and spool housing thoroughly to prevent any grit or metallic debris from entering the system. Compare the free height of the old spring to the new one to verify tension loss; replace any worn matching spools if needed. Lubricate the spring and valve spool with clean hydraulic oil prior to reassembly. FAQ: Q: Can this part replace OEM 100-3564? A: Yes, 100% interchangeable. Dimensions, wire diameter, and spring rate match the original Cat specifications exactly. Q: Is this an OEM or aftermarket replacement? A: This is a premium aftermarket replacement spring built with high-fatigue resistant spring steel. Same operational life, better cost. Q: What equipment does this spring fit? A: It fits a wide array of Cat backhoes (416B/C/D, 420D, 428B/C/D, 430D) and track-type tractors (D5H, D5M, D5N, D6M, D6N). Send us your machine’s serial number or valve group part number to double-check fitment. Q: Should I replace valve springs individually or as a set? A: If your control valve block has multiple identical spools that have worked the same hours, we highly recommend replacing them as a set to keep operating pressures and lever feel consistent. Q: Do you support bulk orders? A: Yes. We offer competitive wholesale terms for hydraulic rebuild centers, fleet repair shops, and distributors. Contact our sales desk directly for pricing.
