This is the genuine Lippert OEM replacement motor assembly built on the IG-42 platform that powers two distinct systems: the Electric In-Wall® (Schwintek) slide-out system and the Schwintek Bed Tilt System. 12V DC, pre-assembled, and backed by a 1-year warranty.\u003c\/p\u003e\n\u003ch3\u003eHigh-Torque 500:1 — Power for Demanding Applications\u003c\/h3\u003e\n\u003cp\u003eThe 325979's \u003cstrong\u003e500:1 gear ratio\u003c\/strong\u003e delivers substantially more torque than the standard 300:1 motor (236575), making it the right choice for large, heavy, or heavily loaded slide-out rooms — and for the power needed to raise and lower a motorized tilting bed. The higher gear reduction means the motor runs more slowly but with greater mechanical advantage, so it's the correct pick wherever a 300:1 motor proves insufficient, or where your system was originally equipped with a 500:1 unit. If you're still diagnosing the issue, our \u003ca href=\"https:\/\/thervsurplus.com\/blogs\/news\/rv-slide-out-moves-slowly-or-stuck\"\u003eguide to fixing an RV slide-out that moves slowly or gets stuck\u003c\/a\u003e can help you confirm the motor is the cause before you order.\u003c\/p\u003e\n\u003ch3\u003e⚠️ \"Without Socket Screw\" — Verify Before Ordering\u003c\/h3\u003e\n\u003cp\u003eThis is the \u003cstrong\u003e\"without socket screw\"\u003c\/strong\u003e variant, and that's not a minor detail — it's a specific configuration. Some In-Wall® motor installations use a socket head cap screw (set screw) to secure the motor in the wall channel; others, including those the 325979 is built for, do not. Installing the wrong configuration can prevent the motor from seating properly. \u003cstrong\u003eBefore ordering, check your existing motor:\u003c\/strong\u003e if a set screw is present in the housing or wall channel mount, you need a different variant (such as the 287298). If no set screw is used, the 325979 is correct.\u003c\/p\u003e\n\u003ch3\u003e⚠️ Match the Gear Ratio — Don't Mix 500:1 and 300:1\u003c\/h3\u003e\n\u003cp\u003eDo not substitute a 300:1 motor for a 500:1 system or vice versa. The controller tracks motor revolutions for synchronization, so mismatched ratios between the two motors on the same slide will cause tracking errors. \u003cstrong\u003eBoth motors in a slide-out pair must share the same gear ratio.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eDual-System Use\u003c\/h3\u003e\n\u003cp\u003eThe same physical IG-42 motor serves two applications:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectric In-Wall® (Schwintek) Slide-Out:\u003c\/strong\u003e Two motors mount in the upper corners of the slide wall (one per side), each driving a gear rack that extends and retracts the room.
