A sleeve bearing puller for removing sleeve bearings such as camshaft bushings from engine cylinder blocks including a pair of expandable and contractable half cylinder shaped extractors having an outer end pulling flange and internal longitudinally spaced cam surfaces, guide pins between the extractors for guiding them in parallel relation between expanded and contracted positions, and expander mandrel between the extractors having longitudinally spaced cam surfaces for expanding the extractors in parallel relation in response to a pull on the mandrel, and a garter spring encircling the extractors holding the extractors on the expander mandrel. |
