Approval Point | Buyer Review |
|---|---|
Reference | 20811209 |
Electrical | 12V; 8W; verify under load |
Connector | Lead wire |
Mechanical | Compare bore, height, body shape and retaining method |
Machine Evidence | Automotive hydraulic valve service using the 20811209 cylindrical lead-wire coil construction |
Separate electrical command, component movement and final machine response so the actual wiring or hydraulic fault is not hidden by parts replacement.
Observed Condition | Recommended Check |
|---|---|
No magnetic pull | Check loaded voltage, ground, continuity and coil resistance. |
Intermittent operation | Inspect terminal retention, lead damage and heat-related winding faults. |
Excessive heating | Confirm voltage, wattage, duty cycle and free valve-stem movement. |
Connector damage | Inspect keying, seals, corrosion and harness side loading. |
Correct coil, no hydraulic response | Inspect the armature, spool, oil cleanliness and machine command. |
When a sample moves into volume production, keep the verified measurements and test result in the service record. Approve the complete old marking, 12v rating, 8w power reference, lead wire, coil bore, body height and retaining method. A matching voltage alone does not prove fit. Send straight-on connector, top-bore and side-profile photographs with measurements so the replacement is selected from electrical and mechanical evidence.
When a hydraulic schematic uses different port labels, keep the verified measurements and test result in the service record. Measure voltage directly across the energized coil while the machine issues the real hydraulic command. An unloaded harness reading can hide resistance at a corroded terminal, relay or ground path. Compare the loaded result with 12v, record polarity where suppression is present and correct the circuit before blaming a new coil for weak magnetic pull.
When a machine harness revision is compared, keep the verified measurements and test result in the service record. Power affects current draw, heat generation and available magnetic force. A replacement with another wattage may fit the valve stem yet operate too weakly, run hotter or exceed a controller output. Confirm 8w from the old label or approved specification, then compare warm current and temperature during sample testing before releasing a bulk order.
When export packing is approved, keep the verified measurements and test result in the service record. Compare pin count, key position, latch direction, cable exit, terminal size and seal arrangement. Similar coil bodies may use a Deutsch, Weatherpack, insert or lead-wire connection that is not electrically or mechanically interchangeable. Photograph the connector face beside a ruler and note any diode or polarity marking before purchasing or adapting the harness.
When an installer measures unexpected voltage drop, keep the verified measurements and test result in the service record. Measure the internal bore diameter, overall height, outside width, shoulder position and retaining-nut clearance on the removed coil. Also record valve-stem length and connector orientation after installation. A coil can have the correct electrical rating but fail to seat fully or interfere with surrounding hardware when its mechanical envelope differs.
When a buyer must approve a cross-reference, keep the verified measurements and test result in the service record. Verify loaded supply voltage, current draw, duty cycle, connector resistance and whether the hydraulic armature reaches full travel. A stuck valve can keep magnetic demand high, while overvoltage or the wrong wattage can overheat the winding. Inspect oil contamination and valve movement before replacing the coil again so the root cause is corrected.
When an emergency field repair is reviewed, keep the verified measurements and test result in the service record. Disconnect power and compare measured resistance at a stable temperature with an approved sample of the same 12v and 8w version. An open circuit indicates a broken winding, while an unusually low value suggests shorted turns. Resistance alone cannot confirm hydraulic valve movement, so complete a loaded-voltage and functional test as well.
Send the complete old marking or component evidence, confirmed voltage, machine information, clear photos, measurements and required quantity for a fitment-focused B2B quotation.
