AP Astro Pneumatic 78830 Hub, Drum & Rotor Puller Kit — Heavy-Duty 8.5-Ton, Forged Arms (Up to 14")

The AP Astro Pneumatic 78830 is a heavy-duty, forged hub, drum and brake rotor puller kit designed to remove seized or press-fit wheel hubs and drums quickly and safely using a 1-1/4" drive.

Built from the same alloy used in Astro's professional ball joint presses, this kit delivers up to an 8.5-ton rated pulling force and a versatile set of adapters and arms to handle a wide range of hub sizes and brake components. It works with a 1-1/4" socket and a 1-1/4" or 32mm wrench and is configured for use with an impact wrench or ratchet for stubborn, rusted, or press-fit parts.

How does the 78830 kit handle different hub and rotor sizes?

The kit includes multiple hub adapters and adjustable puller arms so you can match the tool to small passenger car hubs or larger truck applications. Arms spread up to 14" to reach wide hubs, and the three included hub adapters fit a variety of center bore configurations.

• Small, medium and large hub adapters to fit varied hub diameters
• Forged hub and drum/rotor puller arms with raised stops for secure engagement
• Arms spread capability up to 14" for wider hubs

What makes this puller durable and suitable for heavy service?

All major load-bearing components are forged from the same high-strength alloy used in Astro's ball joint presses, delivering reliable performance under repeated high loads. The kit is rated to 8.5 tons and includes hardened washers and Grade 8 drive bolts to resist bending and wear during tough jobs.

• Forged T-bar and puller arms for long-term durability
• Long 7/8" thread 1-1/4" drive and Grade 8 drive bolt for strength
• Hardened washers and hex nuts to maintain integrity under load

How do I use the 78830 safely and efficiently on stubborn hubs?

Position the correct hub adapter, align the forged arms, and use a 1-1/4" socket with an impact wrench or a 1-1/4"/32mm wrench to apply steady force. For extremely stubborn parts the arm stops allow the use of ratchet straps (not included) to hold the arms while extracting the hub or rotor.

• Use a 1-1/4" socket with an impact wrench or a 1-1/4"/32mm wrench
• Raised arm stops let you secure puller arms with straps for extra leverage
• Includes long and short hex nuts for setup flexibility and clearance

What components are included and how do they improve workflow?

The kit comes complete with specialized hardware to get straight to work: long thread drive, forged arms, adapters, nuts and hardened washers. Having the right adapter and hardened parts on hand reduces downtime and avoids the need for improvised solutions that can damage hubs or rotors.

• Long 7/8" thread 1-1/4" drive for deep engagement
• Forged drum/rotor and hub puller arms for stable extraction
• Long and short hex nuts plus hardened washers for versatile setups

Who this is for: Technicians, DIY mechanics, and fleet maintenance crews who frequently remove wheel hubs, drums or brake rotors from passenger cars, light trucks and some heavy-duty applications will benefit from the AP Astro Pneumatic 78830 kit. It’s best suited to users who need a rugged, reusable pulling solution that handles seized or press-fit components without relying on makeshift tools.
