Bahco 4532-OAB/S puller accessory

Replacement screw for a two-arm puller by BAHCO, intended as the threaded central screw component for model 4532-OAB/S. The screw measures 135 mm in overall length and has a mass of 170 g. It is designed to transfer axial force from the puller crossbolt to the item being removed, restoring the mechanical function of a two-arm puller when the original screw is damaged, worn or missing.

Advantages

This replacement screw is manufactured to fit the specified two-arm puller design, offering the correct thread engagement and length for reliable axial pressure during disassembly tasks. Its steel construction provides durability and resistance to bending under normal workshop loads. Because it directly replaces the central threaded component, it preserves the puller’s original geometry and clamping characteristics, allowing consistent, controlled removal of bearings, gears and pulleys.

Suitable for

• Repairing or restoring a two-arm (two-jaw) puller where the central screw is damaged or lost
• Workshop maintenance tasks involving removal of bearings, gears, pulleys and similar press-fit parts
• Routine servicing of automotive, industrial and agricultural equipment requiring controlled axial extraction

Key specifications

• Overall length: 135 mm
• Weight: 170 g
• Function: central threaded screw for two-arm puller to apply axial force
• Material: steel (suitable for workshop use and normal mechanical loads)

How to use

Inspect the puller and the replacement screw for any visible damage before installation. Thread the screw into the puller crossbolt or central body by hand until it engages, then use the appropriate wrench to tighten and apply axial pressure to the workpiece. Ensure the puller arms are positioned evenly around the component to be removed and that the screw’s tip bears on the shaft or center point. Operate the screw smoothly, advancing in small increments while monitoring alignment to avoid side loading or slippage. After removal, clean and lightly lubricate threads as needed before storage or reassembly.

Usage recommendations

Use suitable personal protective equipment and follow standard workshop safety procedures. Do not apply excessive torque beyond the rated capacity of the puller assembly; if resistance is unusually high, inspect the assembly and workpiece and use appropriate auxiliary techniques (penetrant, heat, or mechanical impact applied safely) rather than forcing the screw.
