| No. | Question | Standard Answer |
|---|---|---|
| Q1 | Which JCB machines fit solenoid kit 25/220804 459/M2874? | This complete shift solenoid with bracket and bolt is designed for JCB 3CX, 4CX backhoe loaders, also compatible with 3C, 4C, TM310 telescopic handlers. |
| Q2 | What voltage options are available for this transmission solenoid? | Two versions for selection: DC12V and DC24V, match different electrical systems of JCB construction equipment. |
| Q3 | What symptoms show this solenoid is damaged? | Hard gear shifting, obvious jerk during forward/reverse switch, transmission slipping under heavy load, slow vehicle response and rising gearbox oil temperature. |
| Q4 | Does this product include mounting accessories? | Yes, it is a full set containing solenoid valve, fixed bracket and installation bolt, no extra parts need to be purchased separately. |
| Q5 | Is full gearbox disassembly required during replacement? | No, just take out the old valve assembly, install the new one with matched bracket and lock the bolt, split the gearbox valve block is unnecessary. |
| Q6 | What surface treatment ensures long service life? | The spool adopts full ion nitriding hardening, matched double high temperature HNBR sealing rings, effectively reduce wear and prevent oil leakage for long-term use. |
| Q7 | Are 25/220804 and 459/M2874 interchangeable? | Yes, these two numbers are cross reference parts, both refer to the same powershift proportional solenoid assembly for JCB gearbox. |
| Q8 | How to test coil health before installation? | Use a multimeter to measure resistance: 7–8Ω for 12V model, 14–15Ω for 24V model; infinite resistance means open circuit, resistance below 5Ω means short circuit. |
