Every metal part is heat-treated for improved strength, while the floating swivel feature helps center the puller and reduce lateral stress on shaft ends during extraction. The kit is built to be versatile for professional mechanics and informed DIYers who need a reliable, portable solution for pulley and damper removal.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this puller protect the crankshaft during removal?\u003c\/h3\u003e\n\u003cp\u003eThe OEMTOOLS 27187 uses a floating swivel that absorbs off-center loads and keeps the puller force aligned with the shaft. This reduces the chance of scoring or bending the shaft end and prevents damage to keyways and threads. Combined with properly sized bolts, the design encourages smooth, controlled extraction rather than sudden jerks.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFloating swivel centers force to limit lateral stress on the shaft\u003c\/li\u003e\n  \u003cli\u003eHeat-treated arms and bolts resist bending under heavy loads\u003c\/li\u003e\n  \u003cli\u003eCompatible bolts for GM 3300\/3800 ensure correct engagement on those engines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich engines and parts is the kit compatible with?\u003c\/h3\u003e\n\u003cp\u003eThe kit includes metric and SAE fasteners plus specific bolts intended for GM 3300 and 3800 V6 engines, making it suitable for those crankshaft pulley jobs. Beyond GM V6s, the universal jaws and bolt sizes let you remove many harmonic balancers, pulleys, dampers, and gears on a variety of light-duty automotive and small-engine applications.

The set packs into a sturdy blow-mold case to protect parts and keep them organized on the bench or in your toolbox. These features reduce downtime and lower the risk of losing small pieces between jobs.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeat-treated construction for longer service life\u003c\/li\u003e\n  \u003cli\u003eSturdy storage case keeps fasteners and jaws secure\u003c\/li\u003e\n  \u003cli\u003eCompact set fits in most toolboxes for portability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I use the kit safely and effectively?\u003c\/h3\u003e\n\u003cp\u003eStart by matching the correct bolt and jaw size to the balancer or pulley, then hand-thread bolts evenly to seat the puller. Turn the center screw slowly while keeping the tool aligned; do not force or hammer the assembly.
