Stop Solenoid Valve 6681513 | Model-Matched for Bobcat 325 331 S150 T190

Variant Verification by Serial Range — Bobcat skid steers and excavators often share the same base solenoid number but require different connector orientations across production years, which we confirm before shipping.

Why the Same Base Number Ships in Multiple Variants

One part number does not guarantee one physical part across Bobcat generations.

Working through fitment queries from Guangzhou, I have handled cases where the 12V Shutoff Solenoid Valve 6681513 matched the catalog for both an S175 and a T190, yet the connector direction on the S175 variant was rotated compared to the T190 build. The operator forced it, burned the coil within hours, and blamed the part. The real problem was that cross-reference tables passed between sellers rarely note these variant breaks. A serial number or a photograph of the old solenoid's connector face usually resolves the question before anything ships [NEED_CITE: Bobcat service manual variant notation conventions across skid steer serial ranges].

Serial Range Coverage Across Skid Steer and Excavator Lines

The 12V Shutoff Solenoid Valve 6681513 is cataloged for Bobcat skid steer loaders from the early 751 series through the current S150, S160, S175, S185, and T190 models, as well as compact excavators from 325 through 341. However, each model family spans multiple production years, and Bobcat occasionally changed the solenoid harness connector or mounting bracket mid-run. Confirming your exact serial number narrows the field to the correct variant and prevents the trial-fitment cycle that costs downtime.

Connector and Port Position Verification

The physical interface is where most mismatches surface. Before ordering, check three things on your removed 12V Shutoff Solenoid Valve 6681513: the number and arrangement of pins in the electrical connector, the orientation of the connector relative to the solenoid body, and the fuel port thread type and position. These details are not always captured in parts catalogs, and a photograph sent to our technical team allows a side-by-side comparison against our stock before dispatch [NEED_CITE: mobile equipment electrical connector identification standards].

Superseded Number Path and Alternate References

Bobcat has updated part numbers across model generations. If the number on your old solenoid differs from 6681513, it may be a superseded reference that has been consolidated into this number, or it may point to a genuinely different component. We verify cross-reference paths including discontinued numbers, so you know whether the replacement is a direct swap or requires an adapter harness. This verification is part of the pre-order process, not an afterthought.

Specification Impact on Field Performance

The 12V rating means this solenoid operates on standard machine electrical system voltage, but coil resistance and current draw vary between variants. A solenoid with incorrect resistance for the machine's controller can cause intermittent shutoff or fail to energize in cold conditions. The ISO 9001 production standard applied here covers dimensional consistency and coil winding verification, which directly affects whether the unit seats cleanly and holds against vibration over a working shift. New aftermarket condition means the unit has not been subjected to prior thermal cycling, unlike pulled or refurbished solenoids where coil insulation may already be degraded [NEED_CITE: solenoid coil insulation degradation factors in diesel engine environments].

The Hidden Cost of a Variant Mismatch

Ordering by number alone and receiving the wrong variant means the machine stays down while the return ships back and the correct unit arrives. In tighter scenarios, the solenoid may bolt on but the connector does not mate, leading to improvised wiring that introduces resistance and heat at the junction. Early coil failure then follows, and the diagnosis points at the new part rather than the bad connection. Each cycle of this pattern costs a day or more of equipment availability on site [NEED_CITE: equipment downtime cost impact from incorrect part fitment].

What Sets This Supply Channel Apart

We produce selected part lines in our own facility and source the remainder from qualified ISO-certified partners, so the warranty terms apply equally across the range. Eight product categories under one account mean that if your repair also needs fuel filters, gaskets, or a seal kit, everything ships as a single consignment from the Guangzhou warehouse. Minimum order is one piece — there is no MOQ blocking an emergency single-unit purchase. Part identification works from a part number, a machine model, a photograph, or a nameplate image. Cross-reference verification covers superseded and alternate numbers so you do not rely on copied tables. For fleet buyers or distributors, a sample is available for fitment trial before any bulk commitment.

Documentation & Verification

• Commercial invoice and packing list referencing machine model for each solenoid unit
• Compatibility and cross-reference sheet listing verified superseded numbers as reference only
• Quality inspection record with coil resistance and dimensional check before dispatch
• Warranty terms covering manufacturing defects for 3-12 months depending on application
• Packing photographs showing connector face and port condition before crating
• HS code and customs documentation support for cross-border aftermarket shipments

Fitment Check Before Installation

• Compare connector pin count and orientation on the new 12V Shutoff Solenoid Valve 6681513 against the removed unit
• Verify fuel port thread type and position before attempting to tighten into the fuel line
• Check mounting bolt spacing against the engine bracket holes before final seating
• Energize the solenoid on the bench with 12V to confirm plunger travel and return spring action
• If connector or dimensions do not match, halt installation and contact us with photographs for variant exchange

Send Us Your Machine Details for Verification

Provide the Bobcat model designation, machine serial number, and ideally a photograph of the old solenoid's connector face and data plate. If the nameplate is worn or painted over, the serial number alone is usually sufficient to confirm which variant of the 12V Shutoff Solenoid Valve 6681513 fits your build. We return a confirmed fitment note with any cross-reference detail before you commit to the order.

Frequently Asked Questions

Q: How do I confirm 6681513 fits my specific Bobcat serial range? A: Send us your machine model and serial number. We cross-check the build date against known variant break points for connector type, port position, and mounting pattern. If the serial falls near a production changeover, we may ask for a photograph of the existing solenoid to confirm before dispatch.

Q: My original part number looks different — is 6681513 the correct superseded replacement? A: Bobcat has consolidated several earlier numbers into this reference over successive model generations. Share the old number and your machine serial, and we verify whether 6681513 is the current valid replacement or whether a different component is required for your specific build.

Q: Why do I see several variants under the same base number? A: Bobcat updated connector orientation, mounting flange dimensions, and port specifications across production years while retaining the same base identifier. These physical differences are not always reflected in online cross-reference tables, which is why serial-level verification matters.

Q: I only have the machine model, no readable part number — can you identify the right solenoid? A: Yes. Provide the machine model and serial number, and we narrow down the correct variant. If the serial plate is also unreadable, a photograph of the solenoid connector and mounting area usually gives enough detail for identification.

Q: Can I order a sample to verify fitment before placing a bulk order? A: A single-piece sample order is available for fitment trial. Once you confirm the variant fits your machine build, bulk orders carry the same specifications and warranty terms as the sample unit.
