AP Astro Pneumatic Tool Company hub, drum & rotor puller kit 78830 — 8.5-ton forged extraction, 1-1/4" drive

The Astro Pneumatic Tool 78830 is a heavy‑duty, forged hub, drum and rotor puller kit designed to safely extract stuck hubs, drums and brake rotors using a 1-1/4" drive and common wrenches.

Built from the same high-strength alloy used in Astro's ball joint presses, this 8.5‑ton rated kit gives professional mechanics and serious DIYers a durable, versatile solution for stubborn wheel components. The kit comes with multiple hub adapters, forged arms for both hubs and drums/rotors, hardened washers and long drive hardware so you can tackle many vehicle makes and hub sizes without improvising parts.

How does the 78830 remove seized hubs, drums and rotors?

The kit uses a central long 7/8" thread drive and Grade 8 drive bolt to apply controlled, high‑force extraction while forged arms pull the component away from the hub assembly. Arms and adapters distribute load evenly to protect mating surfaces and reduce the chance of damage during removal.

• Long 7/8" threaded 1-1/4" drive for deep-engagement pulling
• Grade 8 drive bolt delivers consistent force
• Forged puller arms for hubs and for drums/rotors to fit different geometries
• Small, medium and large hub adapters for multiple hub diameters

What tools and setup do I need to use this kit effectively?

You’ll need a 1-1/4" socket and either a 1-1/4" or 32mm wrench; an impact wrench can be used to speed some steps but manual torque control is also common for delicate work. Drum and rotor arms include raised stops so you can secure ratchet straps (not included) when extra retention is required.

• Compatible with 1-1/4" socket and 1-1/4" or 32mm wrench
• Works with impact wrench for faster operation when appropriate
• Raised stops on drum/rotor arms enable use of ratchet straps for tough extractions
• Arms spread up to 14" to accommodate larger applications

What components are included and how do they improve versatility?

The kit ships as a complete set so you won’t need to source extra adapters for most jobs. Multiple adapters and both long and short hex nuts let you configure the puller for tight spaces, different flange depths, and varied hub diameters.

• Forged T-bar for added leverage and alignment
• Forged hub puller arms plus forged drum/rotor arms for different removal tasks
• Long and short hex nuts for reach and clearance adjustments
• Hardened washers to protect threads and ensure smooth force transmission

Is the 78830 durable and safe for repeated shop use?

Yes — components are forged from a high‑strength alloy and the assembly is rated for 8.5 tons, matching the durability expected in professional environments. Using correct sockets, wrenches and strap retention when specified helps maintain safety and prolongs tool life.

• Forged construction for long service life under repeated loads
• 8.5‑ton rating suitable for demanding removal jobs
• Hardened washers and Grade 8 bolt for dependable thread performance
• Engineered fitment reduces risk of slippage or component damage

Who is this for? The Astro Pneumatic Tool 78830 is aimed at automotive technicians, restoration enthusiasts and serious DIY mechanics who regularly service wheel hubs, brake drums and rotors. If you need a robust, adaptable puller that handles a wide range of hub sizes and can be used with both hand tools and impact tools, this professional‑grade kit provides the reach, strength and adapters to get parts removed quickly and with minimal improvisation.
