Clutch Hub Puller – Triumph & BSA Application

Brief Overview

This is a purpose-built clutch hub puller engineered specifically for Triumph and BSA 500/650/750cc twin-cylinder motorcycles manufactured from 1966 onward. The tool removes the clutch hub from its tapered seat on the main shaft—a critical operation in clutch service and rebuild work. Constructed from stainless steel for corrosion resistance and longevity, this puller delivers the focused, controlled force needed to extract taper-seated components without damage. If your shop services broader British motorcycle platforms or handles multiple hub sizes, also consider a universal multi-application hub puller kit for expanded capability.

Key Features

• Stainless Steel Construction: Resists corrosion and oxidation; maintains finish in damp shop environments.
• 20 TPI External Threads: Matches OEM threading standard for Triumph/BSA clutch hubs; ensures secure engagement and repeatable results.
• Hollow-Bore Design: Internal plunger/anvil applies concentrated force directly to the hub bore, minimizing risk of eccentric loading or component damage.
• Hexagonal Drive End: Accommodates standard wrenches or sockets for leverage; dual flats on barrel provide secondary gripping points if needed.
• Precision Machining: Concentric bore and evenly-spaced threads guarantee smooth operation and reliable seating with each use.

Why This Matters for Your Shop

Specialized Capability: This tool addresses a specific, recurring need in British bike restoration and service. Rather than improvising with generic pullers (which risk damaging expensive or hard-to-source clutch hubs), your technicians have a proper-fit tool that speeds the job and protects the part.

Repeat Demand: Triumph and BSA twins remain popular in the collector/restoration market. A single unit generates multiple service jobs per year in active shops, making this a solid inventory addition.

Durability & Reliability: Stainless construction means no rust or finish degradation between jobs. Unlike painted tools, this puller will look and perform the same after 50 uses as it did on day one—important for resale confidence.
