Application Suitability

Why the Same Part Number Ships in Several Variants

A single reference like 1G820-60022 does not guarantee bolt-in fitment across every Kubota compact machine built over the last two decades.

In mining and rental fleet environments, I have pulled shutoff solenoids from D782 engines that shared a base number but differed in connector pin layout or plunger rod length by a few millimetres. Installing the wrong variant on a Kubota U15 or KX018-4 means the engine either fails to shut down on key-off or the fuel rack never opens fully, leaving operators dealing with run-on or power loss. Cross-reference tables circulated among aftermarket sellers often merge these variants into one line, carrying errors forward [NEED_CITE: Kubota engine serial variant identification for fuel system components]. This 12V Shutoff Solenoid Valve for Kubota D722 / D782 / D902 is supplied only after matching your machine model, engine serial, and connector type.

Machine Serial Ranges and Variant Mapping

Kubota compact excavators like the KX41-3 and U17 span multiple production runs, and engine builds within the same model name shifted between D722, D782, and D902 platforms over successive years. The solenoid housing bolt pattern and plunger stroke length changed with these transitions. Our fitment verification maps OEM references 1G820-60010, 1G820-60012, and 1G820-60020 (cross-reference only) to their specific engine serial ranges so that a 12V Shutoff Solenoid Valve for Kubota D722 / D782 / D902 reaches your machine with confirmed physical compatibility.

Interface Checks That Prevent Return Shipments

The aluminum housing on this stop solenoid holds a ±0.05 mm dimensional tolerance, but matching the bolt pattern alone is not sufficient. Operators replacing units on a Kubota SCL1000 or K008-5 need to verify the electrical connector type and pin configuration, the plunger rod length relative to fuel rack travel, and the orientation of the mounting flange against the injection pump body [NEED_CITE: fuel shutoff solenoid interface verification for compact diesel engines]. A mismatch in any of these three interfaces turns a straightforward swap into a return-and-reship cycle that keeps the machine down for days. We supply a sample unit for physical trial fitment before you commit to a bulk order.

What the Specification Sheet Means on Site

The Class H coil insulation is rated to 180°C, which matters when the solenoid sits next to the exhaust manifold on a D902 in a quarry loading application where ambient heat soaks into the engine bay all shift. The dual-lip nitrile rubber seal, built to SAE J1926, contains fuel at the 30 bar line pressure rating without weeping into the coil cavity — a failure mode that shorts the winding and leaves the engine unable to shut off. Stainless steel plunger rod material resists the corrosion that forms when condensation collects around the fuel rack entry point during overnight cool-downs. Vibration resistance rated to 15g covers the sustained shaking encountered on a KX018-4 working in demolition or trenching, preventing internal contact fatigue that causes intermittent operation.

The Cost of Installing an Unverified Variant

A solenoid that threads in but has a plunger rod two millimetres short will not pull the fuel rack fully closed, and the engine runs on after the key is turned off — a safety incident waiting to happen on any job site. Conversely, a rod that is slightly long restricts full fuel delivery under load, causing the machine to feel sluggish and operators to push the throttle harder, masking the root problem. In a mixed fleet with KX41-3 and U17 units running side by side, fitting the wrong variant from a batch order means pulling the unit back into the workshop for a second teardown [NEED_CITE: diesel engine fuel rack solenoid adjustment and run-on prevention]. Every unverified installation compounds downtime and erodes confidence in aftermarket sourcing.

Why Source This Solenoid Through Our Verification Process

Our own production lines and qualified sourced supply both carry the same quality inspection and six-month warranty, so you receive consistent standards whether the unit ships from our Guangzhou facility or a certified partner. Part identification works from a part number, machine model, engine tag photograph, or even a worn nameplate image — we cross-reference superseded numbers like 1G820-60010 and 1G820-60012 to confirm the correct variant for your engine serial. The one-piece minimum order means a single emergency replacement for a downed K008-5 ships without waiting to meet a quantity threshold. A sample unit is available for physical fitment validation before you place a volume order across your fleet. Technical support confirms connector type, plunger stroke, and housing dimensions against your specific machine.

Documentation & Verification

• Commercial invoice listing each solenoid with its verified OEM cross-reference number (reference only)
• Fitment and cross-reference sheet mapping your machine serial to the confirmed variant
• Dimensional inspection record covering housing tolerance, plunger stroke, and seal seating
• Warranty terms document specifying the six-month manufacturing defect coverage
• Packing photographs showing each unit sealed and labeled before crate closure
• HS code and customs documentation support for international shipment

Fitment Check Before Installation

• Compare the mounting bolt pattern on the new solenoid against the old unit before removing protective caps
• Verify electrical connector pin count and orientation matches the machine wiring harness plug
• Measure plunger rod extension and confirm it matches fuel rack travel on your D722, D782, or D902
• Hand-cycle the plunger to check smooth stroke without binding before applying voltage
• If any dimension or interface does not match, halt installation and contact us with photographs

Requesting a Fitment Confirmation

Send us your Kubota machine model, engine serial number, or a clear photograph of the existing solenoid and its connector. We will return a verified cross-reference match and dimensional confirmation so you can order with confidence, whether you need a single unit for a downed KX018-4 or a batch sample before outfitting an entire rental fleet.

Frequently Asked Questions

Q: How do I confirm this solenoid fits my specific Kubota machine serial number? A: Provide your machine model and the engine serial number from the identification tag. We cross-reference that serial against our variant database to confirm the correct housing bolt pattern, plunger stroke length, and connector type for your specific Kubota D722, D782, or D902 build before confirming the order.

Q: My old part number is 1G820-60010 or 1G820-60012 — is this still the correct replacement? A: These earlier references have been superseded in Kubota documentation. We map 1G820-60010 and 1G820-60012 (cross-reference only) to the current functional equivalent and verify the match against your engine serial range, confirming that bolt pattern, plunger dimensions, and electrical interface align with your machine.

Q: Why are there multiple OEM reference numbers for what looks like the same solenoid? A: Kubota revised the solenoid design across different engine generations and machine production runs. Changes in connector type, plunger rod length, or housing flange orientation resulted in new reference numbers. We verify which variant your specific engine serial requires to avoid installing a physically incompatible unit.

Q: I only have my machine model and no readable part number — can you identify the right part? A: Yes. Share your machine model such as KX018-4 or U17 along with a photograph of the engine identification tag or the existing solenoid. We use model-to-engine mapping and visual comparison of connector and housing features to determine the correct 12V Shutoff Solenoid Valve for Kubota D722 / D782 / D902 variant.

Q: Can I get a sample unit to confirm fitment before placing a larger order? A: We supply a single sample unit at a one-piece minimum so you can physically verify housing dimensions, bolt pattern, plunger stroke, and connector interface on your machine. Once fitment is confirmed on your Kubota excavator or loader, you can proceed with a fleet-level order.
