REPSUPPLEMENTS UP1 Blower Wheel Puller — HVAC fan blade & hub remover, fits 5/8" belt and 1/2" direct shafts, 4 adjustable hooks

The REPSUPPLEMENTS UP1 Ultimate Fan Blower and Blade Hub Wheel Puller is a heavy-duty HVAC tool that removes fan blades and blower wheels frozen on motor shafts without damaging the hub or blades.

When a blower wheel or fan blade seizes on a motor shaft, routine maintenance can become time-consuming and risky. The UP1 puller is built to apply controlled pushing or pulling force to free stuck hubs on belt drive shafts (5/8") and direct drive shafts (1/2" or smaller). It ships with four adjustable hooks, three set screws, and an Allen wrench so you can fit a wide range of hub shapes while keeping grips centered and secure.

How does the UP1 remove stubborn blower wheels safely?

The UP1 uses evenly spaced pulling hooks combined with a central drive interface to deliver balanced force, reducing the chance of bending blades or cracking plastic hubs. Sight holes and adjustable set screws help you center the tool precisely over the shaft before applying torque with a wrench or hex key.

• Four pulling hooks for a symmetric grip
• Three set screws for fine alignment and clamping
• Sight holes to confirm exact centering
• Allows use of a standard wrench or hex key to apply force

What shaft sizes and hub dimensions will this puller fit?

The tool is compatible with belt drive shafts up to 5/8" and direct drive motor shafts 1/2" or smaller. It is engineered to engage hubs with an outer diameter up to about 1-7/8", making it suitable for most residential and light commercial blower wheels.

• Fits 5/8" belt drive shafts
• Fits 1/2" or smaller direct drive shafts
• Designed for hubs up to 1-7/8" outer diameter
• Adjustable hooks accommodate varied hub profiles

Which features protect blades and wheels during removal?

Rather than prying against a single point, the UP1 spreads pulling force across multiple hooks to avoid concentrated stress that can deform metal or crack plastic. Its tempered components and controlled alignment reduce slippage and allow gradual extraction without hammering or improvised tools.

• Balanced, multi-hook pulling reduces localized stress
• Designed to avoid contact damage to blade edges and wheel faces
• Sight holes and set screws prevent off-center loading
• Works without hammers, preventing impact damage

What comes in the kit and how do you operate it?

The UP1 kit includes four pulling hooks, three set screws, and an Allen wrench so you have the basic parts required for most removal tasks. Fit the hooks into the hub, use the sight holes to center the tool, snug the set screws, then turn the central drive with a wrench or hex key to extract the hub.

• Includes 4 pulling hooks, 3 set screws, and an Allen wrench
• Mount hooks, align with sight holes, tighten set screws
• Apply steady torque with a wrench or hex key
• Works for both pushing and pulling applications

Who is this for: The REPSUPPLEMENTS UP1 is designed for HVAC technicians, maintenance professionals, and DIYers who service furnaces, air handlers, and ventilation systems. It’s best when you need a non-destructive, reliable method to remove seized fan blades or blower wheels from 5/8" belt drive shafts or 1/2" (and smaller) direct drive shafts without resorting to damaging improvised techniques.
