What Arrives Before the Machine Can Move Again

A verified 12V Stop Solenoid 3991167 in stock fast shipping from Guangzhou, dispatched the same working day when the order lands before cutoff.

I once spent an entire afternoon cross-referencing a faded nameplate photo from a quarry site in Zhaoqing. The operator had sent a blurry shot of a Cummins 4BT tag — half the characters were obscured by grease and paint overspray. We shipped what looked right, and three days later the machine was still sitting idle because the solenoid voltage did not match the harness output. That kind of delay is what happens when confirmation takes longer than the freight itself. [NEED_CITE: common causes of misidentified electrical components on aging construction equipment]

Every hour a Hyundai R130 or R170 sits silent on an urban excavation site, the contractor loses not just machine time but crew productivity downstream. The goal here is simple: confirm the part, confirm the stock, and get it on a truck or a plane before the sun sets.

Confirming the Right Number From a Photograph

When the nameplate on your Cummins 4BT is worn smooth or buried under layers of site grime, the solenoid itself becomes the only reference. We work from close-up photos of the plunger end, the connector housing, and the mounting flange to cross-check against the 3991167 SA-4941-12 interchange reference. This visual identification typically resolves within two hours during business hours — no waiting for a serial number lookup from the dealer network. A 12V Stop Solenoid 3991167 in stock fast shipping means nothing if the number is wrong in the first place, so the confirmation step comes before the dispatch step, always.

How Fast It Actually Gets to Your Site

Stock sits in our Guangzhou warehouse, which is less than an hour from Baiyun airport and the major courier sorting hubs. For domestic shipments within Guangdong and neighboring provinces, next-morning delivery is routine. International express to Southeast Asian ports typically arrives within a few business days; air freight to the Middle East or Africa follows shortly after. We quote the estimated arrival window at the time of order, not after the invoice is paid. [NEED_CITE: typical international air freight transit times for small parcel industrial components]

Reading the Specs That Matter on Site

The Class H insulation rating means the coil winding can tolerate sustained heat exposure up to 180°C without dielectric breakdown — important when the solenoid sits next to the exhaust manifold on a Cummins 4BT that has been running all shift. The IP67 sealing with dual-lip nitrile gaskets keeps water and fine silt out of the plunger bore, which is where most field failures originate on demolition and quarry machines that work in standing water. The ±0.05 mm dimensional tolerance on the plunger travel ensures the fuel rack moves to full cutoff without binding, even after repeated thermal cycling across the -20°C to +85°C operating range.

The Cost of Shipping the Wrong Solenoid

A mismatched stop solenoid does not just sit on the shelf — it extends the machine's downtime by the full round-trip of return freight and replacement dispatch. On a busy urban excavation site where a Hyundai R170 is the only machine capable of reaching the dig depth required, a few extra days of downtime cascades into missed pour schedules and idle crews. The financial exposure is not the price of the solenoid; it is the compounding cost of every hour the machine stays silent.

Why This Part Ships From Guangzhou

Our own production lines and qualified sourced supply carry the same quality inspection and warranty terms, so there is no guessing which channel your solenoid came through. Eight product categories under one account means you can add fuel filters, seal kits, or cabin components to the same consignment without opening a second purchase order. The one-piece minimum order means an emergency single-unit buy does not get blocked by volume thresholds. Guangzhou warehouse stock on common items like this 12V stop solenoid keeps dispatch times measured in hours rather than weeks. Our technical team confirms compatibility against your machine model, serial range, or photograph before the box leaves the shelf.

Send Us the Photo and We Will Confirm the Fit

If your Cummins 4BT nameplate is illegible or the existing solenoid has no visible markings, send a clear photograph of the connector, the mounting flange, and the plunger end. Include your machine model — Hyundai R130 or R170 — and we will verify compatibility against the SA-4941-12 reference and quote the earliest dispatch slot with an estimated arrival window for your location.

Frequently Asked Questions

Q: Is the 12V stop solenoid 3991167 currently in stock? A: Yes, this solenoid is stocked in our Guangzhou warehouse for immediate dispatch. We update inventory counts daily, and common references including SA-4941-12 and 3964627 are kept on the shelf specifically for emergency orders. If you need more than the visible stock, we can confirm replenishment timing within the same conversation.

Q: What is the minimum order quantity? A: One piece. We do not impose volume thresholds on emergency purchases. A single stop solenoid for a downed Hyundai R130 ships with the same documentation and warranty as a bulk order, so your site supervisor can get the machine running without waiting to accumulate a list.

Q: How long will delivery take to my location? A: Transit time depends on destination and chosen freight method. Domestic Guangdong deliveries often arrive the next business day. International express shipments to Southeast Asia or the Middle East typically arrive within a few business days. We provide a specific estimated arrival window when you place the order, not after.

Q: The nameplate on my engine is worn — how do I confirm this is the right part? A: Send us a photograph of the existing solenoid showing the connector type, mounting holes, and plunger length. Combined with your machine model, we cross-check against the SA-4941-12 reference and confirm fitment before anything ships. This visual identification usually resolves within two hours.

Q: What happens if the solenoid does not fit when it arrives? A: Contact us immediately with photos of the fitment issue. We will verify the discrepancy against your machine details and arrange a replacement or resolution under our six-month warranty. Keeping the original packaging and providing clear images speeds up the process considerably.
