Frequently Asked Questions
| FAQ Topic | Question | Answer |
|---|---|---|
| Model Compatibility | What JCB models do these pressure sensors fit? | These sensors cover a comprehensive range of JCB backhoe loaders (including 3CX, 4CX), telehandlers, wheel loaders, excavators, and compact equipment. The five OEM part numbers represent different model year ranges and machine series. Always match the number stamped on your old sensor for the most accurate replacement. |
| Cross-Reference | Why are there five different part numbers? | JCB uses different part numbers across various model years, engine types, and equipment series. 701/80402, 320/06194, 335/C6732, 332-C0937, and 335/C4128 may have identical form and function but differ in connector orientation, pressure range calibration, or minor revision updates. The COGENG sensors are manufactured to match each specific OEM variant. |
| Sensor Application | What do these sensors measure? | Depending on the specific part number and mounting location, these sensors can monitor engine oil pressure, hydraulic system pressure, transmission oil pressure, brake system pressure, or pilot control pressure on JCB equipment. |
| Direct Replacement | Are COGENG sensors truly plug-and-play? | Yes. Every COGENG sensor is manufactured to exact OEM electrical, mechanical, and calibration specifications. Connectors are pre-configured with the correct pinout. Output signal curves match OEM requirements precisely. No wiring modifications, soldering, or ECU reprogramming is needed. |
| Material & Build Quality | What materials are used in these sensors? | The sensor body is constructed from high-strength iron/steel for maximum durability under severe vibration and pressure spikes. Sealing elements are made from oil and high-temperature resistant rubber (Viton/Nitrile). COGENG holds ISO9001 quality management certification. |
| Installation Tips | What are the critical points for a successful installation? | The three most critical points are: 1) Clean the port thoroughly before installing the new sensor. 2) Always replace the O-ring with a new lubricated seal. 3) Torque correctly — under-tightening causes leaks, over-tightening damages threads and the sensor body. |
| Troubleshooting | What if the fault code or warning light persists after replacement? | Systematically check: 1) Harness connector is fully seated and clicked into place. 2) No bent, corroded, or pushed-back pins in the connector. 3) Correct sensor variant for your specific machine serial number. 4) Wiring harness continuity between sensor and ECU (check for shorts or opens). 5) Actual system pressure verified with a mechanical test gauge. |
| Order & Logistics | What are the payment, packaging, and shipping details? | Payment Terms: T/T, Western Union, L/C, MoneyGram, D/A, D/P. MOQ: Acceptable trial order with no minimum quantity. Packing: PP bag inside, carton box outside. Shipping: By air, by sea, or by express (FedEx, UPS, DHL, TNT) from Guangdong, China. Supply Capacity: 500 PCS. |
Frequently Asked Questions
Q: What are the symptoms of a failing hydraulic pressure sensor on JCB equipment?
A: Common symptoms include inaccurate or absent pressure readings on the display panel, active diagnostic trouble codes related to the pressure sensor circuit, degraded hydraulic performance or unexpected power reduction, the machine entering a failsafe or limp mode, intermittent hydraulic function response, or the engine control system failing to properly match engine speed to hydraulic load demand. A faulty pressure sensor can significantly impact machine productivity across backhoe, telehandler, excavator, and tractor applications.
Q: Is this pressure sensor compatible with both backhoe and excavator JCB models?
A: Yes, the 320/06194 is a versatile sensor used across multiple JCB equipment families including backhoe loaders (3CX, 4CX), Loadall telehandlers (520-40 to 560-80), JS series excavators (JS130 to JS330), and Fastrac tractors. This wide compatibility makes it a common service part across mixed JCB fleets. Always verify the specific part number for your machine before ordering.
Q: Is this sensor a direct plug-and-play replacement?
A: Yes, the COGENG 320/06194 pressure sensor is manufactured to exact OEM specifications for thread size, electrical connector type, pressure range, switching characteristics, and mounting dimensions. It is a heavy-duty, direct plug-and-play replacement requiring no wiring modifications or adapters when installed on compatible JCB equipment.
Q: What makes this a "heavy-duty" pressure switch?
A: The COGENG 320/06194 pressure sensor is built with robust materials and construction designed to withstand the demanding conditions of heavy machinery operation including extreme temperatures, continuous vibration, hydraulic pressure spikes, and exposure to hydraulic fluid and environmental contaminants. It meets or exceeds OEM durability specifications for demanding backhoe, telehandler, excavator, and tractor applications.
Q: What is the warranty coverage for this pressure sensor?
A: COGENG provides a standard 12-month warranty against manufacturing defects from the date of installation. Proof of purchase and installation by a qualified technician are required. Warranty does not cover failure caused by hydraulic fluid contamination, over-pressurization, improper installation, overtightening, thread damage, or use on incompatible equipment.
Q: What should I check before installing the new pressure sensor?
A: Before installation, verify the hydraulic system is fully depressurized, inspect the sensor mounting port for debris or damage, check the electrical connector for corrosion, and apply the appropriate thread sealant if specified by the service manual. Torque the sensor to manufacturer specifications to prevent thread damage or hydraulic leaks. Contaminated hydraulic fluid can damage the new sensor, so verify fluid cleanliness and replace hydraulic filters if necessary.
