OTC ROBINAIR BOSCH - ACH 4420 Pilot Bearing Puller Attachment
The OTC ROBINAIR BOSCH - ACH 4420 Pilot Bearing Puller Attachment is engineered for automotive technicians who need a reliable, precision puller for pilot bearings and tight press-fit components. Designed as an attachment to expand puller capability, this compact tool delivers controlled extraction with minimal risk of housing damage. It integrates cleanly into standard service workflows and complements a technician's pliers and puller set.
Cutting Pliers Compatibility
Although this attachment is not a cutting tool, it is intended to work alongside cutting pliers in a complete technician kit. Use cutting pliers for trimming or freeing retaining elements, then switch to the 4420 attachment to extract pilot bearings without impacting adjacent surfaces. The attachment improves workflow efficiency by reducing tool changes and ensuring a precise grip point for extraction.
Mechanic Pliers And Service Use
Built for mechanic pliers environments, the 4420 attachment addresses common service needs in transmissions, flywheels, and other driveline assemblies. Its robust seating and pull alignment reduce slippage and allow technicians to apply steady force with existing puller bodies or pliers-style adapters. The geometry is optimized for pilot bearing profiles, making it a practical addition to professional repair bays and mobile service setups.
Heavy Duty Pliers Quality
Constructed with durable materials and a service-grade finish, this attachment meets the expectations of heavy duty pliers users who require repeatable performance under workshop stresses. The design focuses on longevity, corrosion resistance, and secure engagement, giving technicians confidence during repetitive removals and high-torque tasks.
For shops that prioritize precision, durability, and compatibility with common pliers and puller systems, the OTC ROBINAIR BOSCH - ACH 4420 offers a targeted solution to pilot bearing extraction challenges. Fast shipping.
