Description

The Bosch 4531-20 is a harmonic balancer puller and installer set designed for the easy removal and installation of most harmonic balancers and drive pulleys. It features a bearing-centered circular 2/3-way puller flange that accommodates 2 1/2" to 4 1/4" bolt circles.

This set includes an assortment of metric and fractional bolts and adapters to provide wide pulling coverage. A heavy-duty, 3/4" diameter forcing screw is internally threaded to fit the eight included adapters for harmonic balancer installation. The adapters feature sizes such as M16 x 2.0, M14 x 1.5, M12 x 1.5, 1/2"-20, 7/16"-20, 3/4"-16, 5/8"-18, and 9/16"-18. All components are kept organized in a blow-molded plastic storage case.
