| No. | Question & Answer |
|---|---|
| Q1 | Q: Which forklifts & mini excavators fit ZVEZDA 31A90-00601 oil pressure switch? A: Direct replacement for all machinery with Mitsubishi S4S/S4Q2/S6S engine, interchange OE 31A9000601 / MM409580, standard external thread screw install without modifying engine oil gallery. In stock, ship within 1–7 working days. |
| Q2 | Q: Oil pressure warning lamp still fails to light at low pressure after replacement? A: Aged stainless steel diaphragm leads to drifted pressure trigger value, replace complete ZVEZDA integrated oil pressure switch to restore stable low pressure alarm function. |
| Q3 | Q: Can this oil pressure switch replace intake MAP sensor or coolant temperature sensor? A: Not interchangeable. This mechanical lube oil pressure alarm sensor detects engine lubricant pressure; MAP sensor measures intake air pressure, water temp sensor monitors cooling liquid temperature, different medium and detection principle. |
| Q4 | Q: Core advantages of ZVEZDA 31A90-00601 oil pressure warning switch? A: High fatigue stainless steel sensing diaphragm, stable fixed low pressure trigger threshold, thick anti-rust zinc plated thread housing, soft grey oil-proof insulation boot, double-layer HNBR high temp anti-leakage sealing, OEM standard thread size direct bolt replacement, neutral unbranded packaging, perfectly match Mitsubishi S4S/S4Q2/S6S engine lubrication safety alarm system. |
