Blind Hole & Pilot Bearing Puller Kit - OTC Tools and Equipment

The OTC 6981 Blind Hole & Pilot Bearing Puller Kit provides professional technicians with a precise and reliable solution for extracting internal pilot and blind hole bearings. Engineered for controlled, damage-free removal, this specialized toolset facilitates efficient service in challenging automotive and industrial applications where traditional pullers cannot access the bearing. It ensures the preservation of critical components during demanding maintenance and repair tasks.

Key Features

• Versatile Bearing Extraction: Designed to accommodate a wide range of common pilot and blind hole bearing sizes, covering inner diameters from 5/16" to 1-1/4". This versatility makes it suitable for passenger cars, light trucks, and various heavy-duty powertrain and industrial machinery.
• Secure Internal Grip: Innovative expanding collets engage positively behind the bearing's inner race, ensuring secure engagement and significantly reducing the chance of slippage during high-load extractions.
• Controlled, Straight Pulls: Engineered for in-line pulling, this kit minimizes side loading to help prevent potential damage to sensitive components like crankshafts, housings, and critical bores. The unique pin adapter allows for use with either a slide hammer or a pulling bridge for adaptable force application.
• Professional-Grade Durability: Built with heavy-duty OTC construction, the components of the 6981 kit are forged and/or machined in Owatonna, MN, and designed to withstand continuous use and the rigorous demands of professional service environments. It also includes a Limited Lifetime Warranty.
• Organized and Portable Storage: A durable, blow-molded case keeps all components systematically organized, protected, and easily transportable between workstations or job sites.
