My analysis of this product showed that it is a high-quality flywheel puller that provides exceptional performance. The OTC 4864 1 Flywheel Puller is a versatile tool that can be easily used by novice automotive enthusiasts as well as experienced mechanics. It has a sturdy construction and is made of durable materials that ensure long-lasting use. The only con i have noticed is that it might not fit all flywheels .Overall it is an excellent addition to my collection of automotive tools and is a must-have for anyone who frequently works on motorcycles..
