Built with durable components including a grade 8.8 threaded stud, washers, and flange nut, this tool is designed for repeated use in both professional and DIY environments.

HARMONIC BALANCER DAMPER PULLEY BOLT AND INSTALL TOOL FITS
Used on my LQ4 rebuild and this install tool made the bolt install the easiest part of build. Pressed the HB into the front seal and onto the crank snout no issues. left timing cover slightly loose and rotated TDC 360 degrees and torqued down the HB bolt. Then rotated again and torqued down the timing cover bolts - all went perfectly.
