JIMS Cylinder Lock Nut (Manufacturer's Ref: 5809)
A robust workshop tool designed for bikers and mechanics working on Harley blocks. This blue retaining nut allows for the temporary locking of a cylinder during the installation of the second piston and its rings, and keeps the cylinders in place during the removal of the cylinder heads. Practical design: a thread at each end, one compatible with Twin Cam engines, the other with Milwaukee Eight® — useful if you are working on classic or touring models.
Compact and designed for the workshop, this nut saves you from improvising temporary solutions during delicate engine operations (pistons, rings, cylinder heads). Particularly suitable for Vintage/Classic and Touring categories and the mentioned Harley mechanics. Keep it in your toolbox when working on Twin Cam or Milwaukee Eight®.
