Puller - Assenmacher Specialty Tools

The Assenmacher Specialty Tools 21-6 Puller is engineered for the precise and damage-free removal of pinion bearing races. This specialized tool provides controlled force within its 36–46 mm operating range, making it essential for professional transmission and driveline service. Its robust construction ensures reliable performance in demanding automotive and industrial shop environments, facilitating non-destructive removal of components.

Key Features

• Versatile Operating Range (36–46 mm): Designed to accommodate common small bearing races found in manual and automatic transmissions, differentials, and gearboxes.
• Pinion Bearing Race Specific Design: Facilitates the removal of the outer pinion bearing race from the transmission case without requiring heat or aggressive prying, thereby protecting delicate surrounding components and ensuring efficient bearing removal.
• High-Strength Steel Construction: Manufactured from durable steel to endure continuous loads, ensuring extended tool life and consistent performance under rigorous professional use.
• Secure, Controlled Grip: Features a precisely engineered jaw profile that firmly grips the bearing race, delivering consistent pulling force while minimizing slippage and reducing the risk of damage to the transmission housing.
• Optional Spindle Compatibility: Integrates seamlessly with the Assenmacher #22-2 spindle (sold separately) for applying even, centered force during the bearing race removal process.
• Compact Service Profile: Its slim design allows for access into tight transmission cases, making it suitable for both bench work and in-vehicle service where space is restricted.

Applications

This puller is an indispensable tool for passenger car and light truck transmission rebuilds, particularly for the critical task of removing pinion bearing races during teardown and overhaul procedures. Its adaptable size range also makes it suitable for extracting similar bearings and races found in differentials and transfer cases. It serves as an ideal choice for transmission specialists, driveline shops, and general repair facilities that regularly service OEM and remanufactured units.
