Technical Specifications

Application Suitability

Why the Same Part Number Ships in Four Variants

The base reference SBA185206083 covers multiple physical configurations across the New Holland TC and Boomer lines.

A buyer ordering strictly by the printed number often receives a unit whose connector points the wrong way or whose flange bolt pattern is offset by a few millimeters. We have seen tractors sit idle for days because the replacement solenoid arrived with a straight plug where the harness required a 90-degree elbow. Catalog tables rarely capture these production splits, and the machine nameplate alone is not enough to resolve them [NEED_CITE: New Holland TC series production variant documentation]. This 12V Fuel Shut Off Solenoid SBA185206083 for New Holland TC Series / Shibaura ISM N844 cross reference fitment demand means every inquiry must be matched against serial range and physical interface, not just a number string.

Mapping the Full TC, TZ, Boomer and Workmaster Range

The application list spans more than sixty machine designations, from the compact TC18 to the TC55DA and the larger Boomer 4060. Within that span, the Shibaura ISM N844 engine block appears in several output states, each with a slightly different fuel rail interface. Identifying the correct 12V Fuel Shut Off Solenoid SBA185206083 for New Holland TC Series / Shibaura ISM N844 cross reference fitment starts with the machine serial prefix, then narrows by production year to lock the flange shape and connector type.

Connector Orientation and Flange Interface Checks

The hidden trap with this stop solenoid is the plug direction. On a TC35DA the harness approaches from the left, demanding a specific rotational clocking of the solenoid body; on a Boomer 2035 the same base number may ship with the plug rotated 180 degrees. We compare the removed unit's connector clocking, bolt hole spacing, and plunger protrusion length before confirming dispatch [NEED_CITE: solenoid connector clocking standards for agricultural tractors]. Sending a sample unit for physical test-fit eliminates the guesswork when the existing part label is worn or painted over.

Reading the Specification Sheet for Field Conditions

The ≤35 ms pull-in time ensures the plunger reaches full travel before the starter motor finishes its cranking cycle, preventing fuel starvation on cold mornings. A hold current of ≤0.8A keeps coil temperature within limits during long idle periods in irrigation or municipal mowing duty. The IP65 rating seals against wash-down water and dust ingress common in grain harvest environments, while the -20°C to +85°C operating window covers winter starts and high-ambient summer work without coil derating.

What a Mismatch Actually Costs

A solenoid that bolts on but has the wrong connector forces the technician to splice harness wires in the field, introducing a corrosion point that fails again within months. A unit with incorrect plunger stroke may close the fuel rack partially, causing erratic idle and stalling under load. These hidden defects show up as repeat visits rather than a single clean repair [NEED_CITE: field failure patterns for fuel shut-off solenoids in compact tractors]. Avoiding them requires dimensional comparison, not just catalog lookup.

Why Buyers Source This Part Through XUNPO

Own production on selected lines and qualified sourced supply share one warranty account, so a fleet standardizing on the 12V Fuel Shut Off Solenoid SBA185206083 for New Holland TC Series / Shibaura ISM N844 cross reference fitment deals with a single point of accountability. Eight categories of machine parts ship under one consignment, preventing split freight. Minimum order starts at one piece for emergency replacements, yet sample units are available for fitment trials before bulk commitment. Part identification proceeds from number, machine model, photograph, or nameplate image, and cross-reference verification covers superseded and alternate numbers that other listings carry forward in error.

Documentation & Verification

• Commercial invoice and packing list matching exact SBA185206083 variant shipped
• Part compatibility sheet noting connector orientation and flange variant (reference only)
• Dimensional inspection record covering plunger stroke and bolt pattern
• Warranty terms covering manufacturing defects for 3–12 months
• Packing photographs showing solenoid orientation and protective wrapping
• HS code and customs documentation support for cross-border shipment

Fitment Check Before Installation

• Compare removed solenoid's connector clocking against new unit before wiring
• Measure plunger protrusion and confirm it matches fuel rail seat depth
• Verify bolt hole spacing on brass flange against ISM N844 mounting face
• Energize solenoid on bench to confirm pull-in stroke and hold current draw
• If connector type differs, halt installation and request cross-reference re-check

Inquiry Guidance for Accurate Matching

Provide the full machine model and serial number from the nameplate, or a clear photograph of the existing solenoid showing the connector and flange. If the part label is unreadable, a photo of the engine block casting number and fuel rail area allows our technical team to confirm the correct variant. For fleet orders, share the unit list so we can map each machine to its specific configuration and arrange sample dispatch.

Frequently Asked Questions

Q: How do I confirm this solenoid fits my specific TC/TZ/Boomer variant when multiple models share the same base number? A: Share the machine serial number and a photo of the existing solenoid's connector and flange. We cross-reference the serial range against our variant database to confirm plug orientation, bolt pattern, and plunger stroke before quoting.

Q: My existing part number looks different from SBA185206083 — is it a superseded reference that still cross-references? A: Many earlier numbers were consolidated into this reference over production generations. Send us the old number and we will trace the supersession chain to confirm whether it maps to the same physical configuration your machine requires.

Q: I only have the machine model (no readable nameplate or part number) — can you identify the correct variant? A: Yes. Provide the model designation and, if possible, a photo of the engine compartment showing the fuel rail area. Narrowing by production year and serial prefix lets us determine the correct flange and connector variant.

Q: Why do some listings show the same number but with different connector types or flange shapes? A: The base number covers multiple production splits across the TC and Boomer range. Connector clocking and flange casting changed between model years, so listings that omit variant detail risk shipping a physically incompatible unit.

Q: Can I get a sample to test-fit on my tractor before ordering for the whole fleet? A: Sample units are available for physical fitment trials. Confirm the variant with us first, then we dispatch one piece for bench and on-machine testing before you commit to a fleet-standardization quantity.
