Magnum 3-Jaw Internal and External Slide Hammer Puller (1088)

Getting a solid grip on recessed pilot bearings or external gears requires jaws that will not slip under intense tension. This 3-jaw internal and external slide hammer puller utilizes a secure locking nut to expand the jaws and clip firmly onto the bearing race. Once locked in place, the slide hammer delivers sudden impact force to safely yank out the bearing, saving tradesmen from resorting to destructive prying methods.

Features

• Secure locking nut - expands the 3 jaws to bite firmly into the bearing race, preventing slippage during heavy extraction.
• Internal jaw setup - handles inside diameter capacities from 15mm to 80mm for pulling pilot and blind hole bearings.
• External jaw setup - covers outside capacities of 15mm to 80mm for gripping and pulling small gears and pulleys.
• Heavy slide hammer action - delivers sharp outward shocks to break loose decades of rust and friction securely.

Frequently Asked Questions

How does the locking nut work?

By tightening the nut on the central shaft, it wedges the jaws outward (or inward) to lock them rigidly against the bearing surface before sliding the hammer.
