Fitment: Compatible with Harley Panhead,Shovelhead,Evolution,Twin Cam engines NOT FOR 2006 to present Dyna and all 2007 to present Big Twins Specifications: Use on primaries between front primary chain and motor sprocket Function: Lock primary drive and restrict the sprocket teeth movement This is a necessary tool for removing or installing primary drive components Color: Black Material: Polyurethane Package Included: 1x Primary Drive Locking Tool Review: Used this in my 2002 Harley Davidson Road King. It works great to hold the chain and enable one to loosen the various nuts needed to remove the primary drive casing as part of belt drive replacement. Review: This is a fantastic tool. I'm a certified mechanic, and have worked on HD professionally. I've seen these things get chewed up after a handful of uses. This thing is tough. I curse a lot for emphasis, and I'm hold back the F word here. But this thing is F'n rad! When I hit that 45ยฐ on the compensator torquing it down it barely did anything to this bad boy. Couldn't be happier with it!
