DAYUAN Harmonic Balancer & Flywheel Puller Set — 46‑Piece Kit, Heat‑Treated Yoke & Molded Case

DAYUAN's 46-piece harmonic balancer and flywheel puller set is a complete, professional-grade kit designed to remove harmonic balancers, steering wheels, pulleys and flywheels across a wide range of vehicles.

This versatile kit groups a heat-treated steel yoke, a heavy-duty pressure screw and 30 different bolts and adapters into a molded storage case so you can tackle multiple thread sizes and hole patterns without improvising. The parts list covers common metric and imperial threads plus centering adapters and washers so the kit works on two- and three-hole mounting patterns and many European, Asian and domestic applications.

How does this kit adapt to different pulley and flywheel configurations?

The DAYUAN set includes multiple bolt lengths, metric and imperial sizes, plus centering and flat-shaft adapters so you can fit the puller to varied hub diameters and bolt patterns. The yoke accepts two- and three-hole setups and the floating swivel on the pressure screw reduces lateral stress during extraction.

• 30 bolt sizes: metric M8/M10 and common imperial threads
• Two centering adapters and one flat shaft adapter for alignment
• Yoke with four slots supports two- or three-hole mounting patterns
• Floating swivel on pressure screw to protect shaft ends

What components are included and why each matters?

Every component is chosen to let you configure the puller for a specific vehicle: the heat-treated alloy yoke provides the main pulling force, the pressure screw applies centered extraction force, and a wide selection of bolts and washers let you fasten the yoke to different hubs. The molded case keeps small parts organized and ready for the next job.

• Heat-treated alloy steel yoke for strength and durability
• 5" pressure screw with 3/4"-16 thread for robust extraction force
• 30 different bolts including M8 x 1.25, M10 x 1.5, and multiple imperial sizes
• Molded storage case to protect and organize components

How do you use the set safely and effectively?

Start by matching the correct bolt thread and length to the hub, install the yoke into the mounting holes, center the pressure screw using the adapter that fits the shaft, and turn the screw steadily to draw the part off. The floating swivel on the pressure screw and the variety of bolt lengths help keep force centered to avoid damaging the shaft or hub face.

• Select matching bolt thread and length for secure engagement
• Use centering adapter to align pressure screw to shaft center
• Turn the pressure screw evenly; avoid sudden jerks or hammering
• Inspect threads and components before reassembly to ensure fit

Which maintenance and storage tips prolong kit life?

Wipe components clean after use, lightly oil the pressure screw threads to prevent corrosion, and store parts in the molded case to avoid lost pieces. Periodically inspect the yoke and bolts for wear or thread damage before each job to maintain safe pulling performance.

• Clean and dry components after use to prevent rust
• Lubricate pressure screw threads for smooth operation
• Keep bolts and adapters in the molded case to prevent loss
• Replace any rounded or damaged bolts before reuse

Who is this for: mechanics, restoration hobbyists and DIY enthusiasts working on engines, steering columns or accessory pulleys will appreciate this DAYUAN kit when facing seized harmonic balancers, stuck steering wheels or tight pulleys. It suits automotive shops and serious home garages that need a single, adaptable puller solution covering both metric and imperial fasteners without relying on improvised tools.
