It is the hardest-working component in an HPA engine and, being an electromechanical part with a finite duty cycle, it is the one most likely to need replacing before anything else does. When an engine starts double-feeding, firing weakly, or refusing to cycle at pressures it used to hold, the solenoid is the first thing a tech reaches for.\u003c\/p\u003e\n\u003cp\u003eWolverine use a common solenoid across four of their engine families, which is unusually convenient for anyone who runs more than one platform. The same part serves an INFERNO in an M4 gearbox, a HYDRA in an offset-nozzle build, an SMP, and a HAVOC. If you keep a spare in your box, it covers whichever of those goes down at a game.\u003c\/p\u003e\n\u003cp\u003eWe are an authorised Wolverine tech centre, so if you would rather not open the engine yourself, we can diagnose the fault and fit the part on the bench. A solenoid swap is straightforward on most platforms but does require the engine out and the electronics disconnected.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePart\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGenuine Wolverine Airsoft replacement solenoid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eEngines covered\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eSMP, HYDRA, INFERNO, HAVOC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eShipping weight\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e0.12 lb (approximately 55 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003ePacked dimensions\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e4 × 2 × 1 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eGood to know\u003c\/h2\u003e\n\u003cp\u003eWolverine do not publish a coil voltage or resistance figure for this part, and we will not quote one we cannot verify. It is sold as the direct replacement for the solenoid already fitted to the engines listed above, so if your engine is one of those, this is the correct component.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know the solenoid is the problem?\u003c\/strong\u003e Typical signs are inconsistent muzzle energy, the engine cycling intermittently, or a distinct click with no shot. Air leaks and a tired o-ring set produce similar symptoms, so it is worth servicing the seals before condemning the solenoid.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill one solenoid really fit all four engines?\u003c\/strong\u003e Yes — this is the shared part across those four Wolverine families. It is not compatible with the BOLT or BOLT M, which use a different architecture.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to re-tune after fitting?\u003c\/strong\u003e Expect to check dwell once the new part is in. A fresh solenoid often responds slightly differently from a worn one, and a short dwell adjustment usually settles it.\u003c\/p\u003e\n\u003cdiv style=\"background:#fffbe6;border-left:4px solid #f0d060;padding:12px 16px;border-radius:0 6px 6px 0;margin:0 0 16px;font-size:13px;\"\u003e\n⚠ \u003cstrong\u003eDepressurise first:\u003c\/strong\u003e disconnect the air line and bleed all residual pressure from the engine before removing any valve component.
