SP-1-22 GEAR BOX INGCO (CIWLI2085)-M-11

The INGCO M-11 Gear Box Assembly (SP-1-22) is a genuine replacement planetary gear set designed for the INGCO CIWLI2085 20V Brushless Cordless Lithium-Ion Impact Wrench (850 Nm fastening / 1000 Nm nut-busting torque). This multi-stage planetary gearbox houses the sun gears, planet carriers, and ring gear in a compact, sealed aluminum casing, efficiently transmitting high-torque from the brushless motor to the output shaft while maintaining variable speeds (0–2400 RPM) and impact rates (0–3200 IPM). Engineered for durability under extreme loads, it features hardened steel gears with helical teeth for smooth, quiet operation and reduced backlash. Replace when experiencing gear grinding, slippage, or torque loss after heavy use (e.g., 200-300 hours), restoring full performance without full tool replacement. As part of INGCO's modular spare system, it's ideal for field repairs in automotive, construction, or assembly applications.

Key Features:

• Planetary Gear Design: 3-4 stage reduction with high-ratio gearing (up to 40:1) for optimal torque multiplication; precision-machined Cr-Mo steel gears resist stripping and wear.
• Sealed Housing: Die-cast aluminum casing with O-ring seals for dust/moisture resistance (IP54 level); includes integrated bearings and retaining clips for vibration dampening.
• Compatibility: Direct OEM fit for CIWLI2085 (20V brushless variants); bolts onto motor stator and output anvil—ensures balanced power flow with no modifications.
• Performance Specs: Supports 3-speed settings (0-900/0-1600/0-2400 RPM) and forward/reverse; heat-treated for continuous duty without overheating.
• Installation Ease: Bolt-on assembly with 6-8 Torx screws; 15-25 minute DIY swap using basic tools—align gear teeth during mating for smooth engagement.

Ideal For:

Mechanics, fabricators, or tradespeople maintaining the CIWLI2085 for demanding tasks like lug nut removal, pallet breaking, or machinery bolting. Essential after exposure to debris or overloads—not compatible with other INGCO models like CIWLI2001 (brushed). Users note its robust rebuild quality, with 4.7+ ratings for reviving torque in high-use scenarios.
