Product Overview
Unlock the heart of your engine’s electrical system with the GOOFIT Professional 28mm Flywheel Puller. Specifically engineered for 4-stroke engines ranging from 49cc to 150cc, this tool is the standard for safely removing the magneto flywheel from the crankshaft without causing damage to expensive engine components.
Precision-forged from high-grade industrial steel, this puller is designed to handle the massive torque required to "pop" a flywheel that has been seated for years. Whether you are a professional mechanic or a DIY enthusiast working on an ATV, Scooter, or Dirt Bike, this tool ensures a clean, professional removal every time.
Technical Specifications
Please verify your flywheel's internal thread diameter before ordering:
| Component | Measurement |
| Inner Thread Diameter | 28mm (1.1") |
| Center Drive Bolt | 14mm (0.55") |
| Compatibility | 4-Stroke 49cc – 150cc Engines |
| Exclusions | Not compatible with Pro-X 150 Go-Kart or BMW G310R |
Key Features
- High-Strength Forged Steel: Built for the toughest jobs. Our high-grade steel construction offers superior toughness and resistance to thread stripping, ensuring the tool maintains its precision even under high-torque applications.
- Safe Mechanical Leverage: Designed to push directly against the crankshaft center. This balanced force prevents the flywheel from warping and protects the crankshaft threads, which can be easily ruined by using hammers or pry bars.
- Professional Grade Precision: The threads are precision-machined to ensure a snug, non-slip fit. This reduces the risk of cross-threading and makes the disassembly process smoother and faster.
- Universal 4-Stroke Fitment: An essential tool for servicing a wide variety of powersports vehicles, including TaoTao, Apollo, SSR, and most other Chinese-manufactured 4-stroke engines.
- Bonus GOOFIT Keychain: Each package includes the professional flywheel puller and a custom GOOFIT keychain as a gift for our loyal customers.
How It Works (Step-by-Step)
- Thread the Bushing: Screw the 28mm outer nut of the puller into the threaded hole of the flywheel. Ensure it is fully seated.
- Align the Center Bolt: Place the center drive bolt against the center hole of the crankshaft.
- Apply Force: Use a wrench to rotate the center bolt. This increases pressure against the crankshaft, creating a mechanical "push" that pops the flywheel off the tapered shaft.
