Mastercool 91000-A Deluxe A/C Clutch Hub Puller & Installer Kit

Description

The Mastercool 91000-A Deluxe A/C Clutch Hub Puller & Installer Kit provides technicians with a complete solution for servicing compressor clutch hubs during automotive A/C repairs. Because the kit includes multiple pullers, installers, and arbors, it supports clutch service across many common compressor platforms.

This kit allows technicians to remove and install clutch hubs using controlled mechanical force, rather than prying or hammering. As a result, it helps protect compressor shafts, bearings, and clutch components during service. In addition, the precision-machined tools help maintain proper alignment, which supports accurate clutch reinstallation and correct air-gap setup.

Designed for professional shop and mobile service environments, the 91000-A kit supports a wide range of domestic and import vehicles. Its modular layout also allows individual components to be replaced as needed, extending the service life of the kit.
