The OTC Heavy Duty Gear Puller, No. 6614, is stout enough for almost any heavy duty application and includes a pair of metric bolts for most applications. The slim design cross block allows more room to set up in tight quarters to pull more gears. The puller has a spread range of removing gears from 2" to 7-1/4" in diameter, including most cam gears. The tempered steel rust inhibitor-coated bolts are graded 10.9, have M12x1.75" threads, and are 90mm in length. The puller has a 5-3/4" long forcing screw threaded 5/8"-18 and has a pulling reach of 3-1/4". The tool includes sliding plates to ensure smaller gear bolts up to 1.2" in diameter are always centered. The puller is treated to resist corrosion and is covered by OTC's lifetime warranty.
