Sleeve puller puck as pictured for Farmall C248 engine. Double groove style allows you to pull/install either 3 7/8" or 4" sleeves.
This listing is for the puck only, you'll use your own 1/2" threaded rod and parallels to complete the set-up. While this tool helps with installation, we still recommend freezing your sleeves and working carefully as you drive new sleeves into your block. Sleeves are fragile and can be broken during installation, even by professionals.
