The tool's screw length and bracket geometry are optimized for clearance on engines, motor housings, and workshop fixtures. It ships with an anti-fall pin that slightly reduces usable bracket span but improves safety during use.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this puller remove bearings and pulleys without slipping or damage?\u003c\/h3\u003e\n\u003cp\u003eThe MANNIFEN 2-jaw design grips components evenly on both sides to apply balanced force to the inner or outer diameter. The central threaded forcing screw pushes on the shaft while the jaws pull the component straight off, minimizing side-load and scoring. Heat-treated chrome-vanadium construction keeps the jaws rigid under torque so they don't deform.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eReversible jaws for internal or external gripping\u003c\/li\u003e\n  \u003cli\u003eBalanced two-arm pull prevents uneven extraction\u003c\/li\u003e\n  \u003cli\u003eForged chrome-vanadium steel for high strength and durability\u003c\/li\u003e\n  \u003cli\u003eAnti-fall pin improves jaw retention during operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat sizes and dimensions should I expect with the 8\" model?\u003c\/h3\u003e\n\u003cp\u003eThis listing is the marked 8\" (200mm) puller; the bracket is nominally 200mm but the anti-fall pin results in a working bracket span of about 175mm. The screw length measures approximately 167mm (6.57 inches) and each claw, when installed on the bracket, offers about 112mm (4.4 inches) of reach. MANNIFEN also offers 4\", 6\", and 10\" variants if you need a different span.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMarked size: 8\" \/ 200mm (nominal)\u003c\/li\u003e\n  \u003cli\u003eUsable bracket span: ≈175mm due to safety pin\u003c\/li\u003e\n  \u003cli\u003eScrew length: ≈167mm (6.57 inches)\u003c\/li\u003e\n  \u003cli\u003eClaw reach: ≈112mm (4.4 inches) when installed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich materials and finishes improve its lifespan and performance?\u003c\/h3\u003e\n\u003cp\u003eThe main body and jaws are forged from chrome-vanadium steel and receive heat treatment to increase toughness and wear resistance. This metallurgical process reduces the risk of bending or cracking under load compared with mild steel pullers. The threaded forcing screw is finished to allow smooth turning while resisting corrosion and galling during repeated workshop use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eForged chrome-vanadium construction for strength\u003c\/li\u003e\n  \u003cli\u003eHeat treatment for improved hardness and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003eSmooth, durable screw finish for reliable operation\u003c\/li\u003e\n  \u003cli\u003eRobust jaws resist deformation during heavy pulls\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I use the reversible jaws safely and effectively?\u003c\/h3\u003e\n\u003cp\u003eChoose the jaw orientation (inside or outside) that matches the component's features, ensure the puller sits square to the shaft, and tighten the center screw gradually while checking alignment. Secure the part to prevent rotation, wear protective eyewear, and use a suitable socket or hex driver on the forcing screw to control torque. Stop and reposition the jaws if the puller starts to tilt or the part binds.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSelect internal or external jaw setup before applying force\u003c\/li\u003e\n  \u003cli\u003eAlign puller centrally on the shaft for even extraction\u003c\/li\u003e\n  \u003cli\u003eTighten the forcing screw slowly, monitoring movement\u003c\/li\u003e\n  \u003cli\u003eUse safety gear and reposition if binding occurs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: The MANNIFEN 8\" 2-jaw puller is intended for mechanics, hobbyists, and small-engine technicians who need a compact but strong extractor for small bearings, pulleys, flywheels, and gears. If you work on motorcycles, scooters, lawn equipment, electric motors, or compact automotive components and want a reversible, heat-treated tool built to withstand repeated use, this model is a practical, workshop-ready choice.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the jaws be used for internal and external pulls?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
