Bearings will usually press easily into plastic stunt scooter wheels, but alloy (metal) core wheels can be extremely difficult. Our 608 tool makes this an easy job, its clever design allows you to install one bearing at a time, and ensures the bearings are not damaged in the process. One side of the plates have a recessed inner lip, ensuring only the outer race of the cartridge is being pushed, so please check they are used the correct way around.
The tool contains a 70mm M8 threaded bar with nuts and washers, and two press plates specifically sized for 608 bearings. You will need two 13mm wrenches to use the tool.
