Product Details
The YEEDA YD58 Series 3-Jaws Gear Pullers solve critical challenges in mechanical component removal: "unstable gripping, tool deformation, and limited size compatibility". With "drop-forged carbon steel + T-shaped thread + white zinc plating" as core strengths, each model caters to distinct heavy-duty maintenance needs:
Drop-Forged Carbon Steel: Strength for Heavy-Duty Use
- Superior Durability: The jaws and beam undergo drop forging, a process that compresses carbon steel into a dense, uniform structure. This makes the pullers 50% stronger than cast alternatives--larger models (e.g., YD58-011, 28") can handle 3000 kg of force, easily removing rusted or press-fit gears in industrial machinery.
- Wear Resistance: Forged carbon steel maintains its shape even after repeated use (300+ component removals), while the T-shaped thread resists stripping--critical for technicians applying high torque to tight components.
3-Jaws Design & T-Shaped Thread: Precision & Stability
- 3-Jaws for Balanced Grip: The three jaws distribute force evenly across the component (e.g., gear, bearing), preventing deformation or cracking. Unlike 2-jaw pullers, this design eliminates slippage, even when removing irregularly shaped parts.
- T-Shaped Thread for Smooth Operation: The thread's wide, sturdy profile ensures steady advancement of the puller's central bolt, allowing technicians to apply gradual, controlled force. This avoids sudden component release, which can cause injury or damage.
White Zinc Plating & Size Versatility
- Anti-Corrosion Protection: The white zinc-plated surface repels oil, grease, and workshop moisture, preventing rust and extending tool life by 40% compared to uncoated pullers. It also simplifies cleaning--debris wipes off easily with a dry cloth.
- Comprehensive Size Range: From 3" (YD58-001, for small bearings in cars) to 28" (YD58-011, for large industrial gears), the series covers nearly all common component sizes. The 3-piece (YD58-012) and 4-piece (YD58-013) sets offer cost-effective solutions for shops needing multiple sizes.
Application Scenarios
Automotive Repair Shop (YD58-002, 4"/100mm)
Scenario Requirement: A shop services 15 sedans monthly, replacing 100mm diameter gears in transmission systems. The shop needs a compact puller for tight engine bays.
Operation Process:
- Setup: Select YD58-002 (4"); adjust the 3 jaws to grip the 100mm gear's inner race; secure the jaws tightly;
- Removal: Turn the central T-shaped thread to apply force--even pressure from the 3 jaws loosens the gear in ~2 minutes;
- Efficiency: 15 sedans serviced in ~30 minutes; the puller's compact size (30×18×21cm carton) fits easily in tool storage;
- Durability: White zinc plating resists transmission oil; no rust after months of daily use.
Effect: Compact design fits engine bays; balanced grip protects gears; corrosion resistance suits automotive use.
Industrial Plant Maintenance (YD58-009, 20"/500mm)
Scenario Requirement: A factory maintains 8 industrial turbines (each with 500mm diameter pulleys) quarterly. The plant needs a heavy-duty puller for large, tight components.
Operation Process:
- Setup: Deploy YD58-009 (20"); position the 3 jaws around the 500mm pulley; use a wrench to tighten the T-shaped thread;
- Removal: Apply gradual torque--forged carbon steel handles 2500 kg force; the pulley separates from the shaft in ~5 minutes;
- Safety: 3-jaw design prevents slippage; no risk of the pulley falling during removal;
- Reliability: The puller withstands factory dust and grease; white zinc plating prevents corrosion.
Effect: Heavy-duty build handles large pulleys; safe operation protects technicians; durability fits industrial conditions.
Agricultural Machinery Yard (YD58-013, 4-Piece Set)
Scenario Requirement: A yard services 10 tractors (with 75mm-200mm gears/bearings) weekly. The yard needs versatile pullers for diverse component sizes.
Operation Process:
- Setup: Use the YD58-013 set (3"+4"+6"+8"); select the 6" (150mm) puller for a tractor's gearbox gear;
- Maintenance: Adjust jaws to grip the gear; turn the thread to remove it--3-jaw balance avoids gear damage;
- Versatility: Switch to the 8" puller for larger bearings; 4-piece set covers all tractor component sizes;
- Storage: The set's compact carton (43.5×26×19cm) saves space in the yard's tool shed.
Effect: Multi-size set fits diverse needs; easy storage optimizes space; reliable performance reduces downtime.
Frequently Asked Questions
Q1: The 3 jaws slip when removing a tight gear. How to fix this?
A1: Slippage is usually due to incorrect jaw positioning or debris. Solutions:
- Align Jaws Properly: Ensure all 3 jaws grip the component's inner/outer race evenly--avoid tilting the puller;
- Clean Contact Surfaces: Wipe grease, rust, or dirt from the jaws and component with a degreaser--debris creates a slippery barrier;
- Tighten Jaws Securely: Before applying torque, fully tighten the jaws around the component--this maximizes grip and prevents movement.
Q2: Can YD58-011 (28"/700mm) be used for small components (e.g., 50mm bearings)?
A2: No. The 28" puller is oversized for small components, leading to:
- Grip Issues: Jaws can't fit tightly around 50mm bearings, causing slippage and component damage;
- Force Wastage: The puller's high load capacity (3000 kg) is unnecessary for small parts, increasing the risk of over-force and component cracking;
- Maneuverability Problems: The large size won't fit in tight spaces (e.g., engine bays) where small components are located. Use YD58-001 (3"/75mm) for 50mm bearings.
Q3: The T-shaped thread is hard to turn. What's the issue?
A3: Stiff threads are caused by rust, debris, or lack of lubrication. Fixes:
- Clean the Thread: Use a wire brush to remove rust or dirt from the T-shaped thread; wipe with a cloth dipped in mineral spirits for stubborn debris;
- Lubricate: Apply a thin layer of lithium-based grease to the thread--this reduces friction and ensures smooth turning;
- Check for Misalignment: Ensure the central bolt is aligned with the puller's beam--misalignment can jam the thread.
Q4: How to maintain the pullers to extend their service life?
A4: Key maintenance steps:
- Post-Use Cleaning: Wipe the jaws, beam, and thread with a dry cloth after each use to remove grease; for heavy buildup, use a mild solvent and dry thoroughly;
- Protect the Coating: Avoid using abrasive tools (e.g., wire brushes) on the white zinc plating--use a soft cloth to prevent scratching;
- Lubricate Threads: Apply grease to the T-shaped thread monthly to prevent rust and ensure smooth operation;
- Store Properly: Keep pullers in a dry, ventilated toolbox (avoid humid workshops); use the original carton for large models to prevent bending during storage.
