Use the correct tool. It can be harmful to your engine to remove a flywheel without the correct flywheel puller. The pullers fit both OEM and Trail Tech flywheels.

Trail Tech does not have flywheel pullers available for these machines:
· The Suzuki LTZ400 uses a DRZ400 Puller
· The Raptor 660 uses a 3-prong Automotive Puller
