Product Details
This high-quality forged 2-jaws gear puller solves critical challenges in mechanical component removal, including unstable gripping, tool deformation, and limited size adaptability. Featuring drop-forged carbon steel construction, white zinc plating, and an adjustable 2-jaw design, it excels in heavy-duty maintenance applications.
Drop-Forged Carbon Steel: Strength for Heavy Use
- Superior Durability: The jaws undergo drop forging, compressing carbon steel into a dense, uniform structure. This makes the puller 40% stronger than cast alternatives—larger models (e.g., YD59-008, 16") can handle 2000 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 (200+ component removals), ensuring long-term reliability.
2-Jaw Adjustable Design: Precision & Versatility
- Adjustable Grip: The 2 jaws can be adjusted to fit different component diameters, providing a secure hold on gears, bearings, and pulleys of various sizes (75mm-400mm). This adaptability eliminates the need for multiple specialized tools.
- Efficient Force Application: The central threaded rod allows for gradual, controlled force application, preventing sudden component release and potential damage or injury.
White Zinc Plating: Corrosion Protection & Longevity
- Anti-Corrosion Shield: The white zinc-plated surface repels oil, grease, and workshop moisture, preventing rust and extending tool life by 30% compared to uncoated pullers. It also simplifies cleaning—debris wipes off easily.
- Professional Aesthetic: The sleek white zinc finish gives the puller a polished, professional look, suitable for both workshop and professional service environments.
Application Scenarios
Automotive Repair Shop (YD59-002, 4"/100mm)
Scenario: A mechanic needs to remove a 100mm diameter bearing from a car's transmission system.
Operation: Adjust the 2 jaws of YD59-002 to grip the bearing's inner race, secure the jaws tightly, then turn the central threaded rod to apply force. The drop-forged steel handles the torque, and the bearing is removed in ~2 minutes.
Effect: Compact size fits engine bays; adjustable jaws ensure a secure grip; corrosion resistance withstands transmission oil.
Industrial Plant Maintenance (YD59-008, 16"/400mm)
Scenario: A technician is tasked with removing a 400mm diameter gear from industrial machinery, rusted from years of use.
Operation: Use YD59-008, adjust the jaws to fit the gear, and apply force via the central rod. The drop-forged carbon steel handles 2000 kg of force, and the gear is removed in ~5 minutes.
Effect: Heavy-duty build handles large gears; corrosion protection suits industrial environments.
Agricultural Machinery Servicing (YD59-005, 10"/250mm)
Scenario: A farmer needs to replace a 250mm pulley on a tractor, seized due to exposure to the elements.
Operation: Deploy YD59-005, adjust the jaws to grip the pulley, and turn the threaded rod. The white zinc plating resists rust from moisture, and the pulley is removed safely.
Effect: Versatile size fits tractor components; corrosion resistance handles outdoor conditions.
Frequently Asked Questions
Q1: The jaws slip off the component when trying to pull. How to fix?
A1: Slippage is usually due to incorrect jaw adjustment or debris. Solutions:
- Adjust Jaws Properly: Ensure the jaws grip the component's inner/outer race evenly
- Clean Surfaces: Wipe grease, rust, or dirt from the component and jaws with a degreaser
- Tighten Securely: Fully tighten the jaws around the component before applying force
Q2: Can this puller be used on stainless steel components?
A2: While drop-forged carbon steel is strong, stainless steel components are extremely hard. Using the puller on them may:
- Require excessive force, risking jaw damage
- Blunt the jaws quickly
For stainless steel, use a puller specifically designed for hardened materials or consider alternative removal methods.
Q3: The central threaded rod is hard to turn. What's wrong?
A3: Stiffness is caused by rust, debris, or lack of lubrication. Fixes:
- Clean the Thread: Use a wire brush to remove rust or dirt from the threaded rod
- Lubricate: Apply a thin layer of lithium-based grease to the thread
- Check Alignment: Ensure the rod is aligned with the puller's frame—misalignment can jam the thread
Q4: How to maintain the puller for long life?
A4: Maintenance steps:
- Clean After Use: Wipe jaws and the rod with a dry cloth; use a mild solvent for heavy grease
- Protect the Coating: Avoid abrasive tools on the white zinc plating
- Lubricate Threads: Apply grease to the threaded rod monthly
- Store Properly: Keep in a dry, ventilated toolbox
