Raymarine ST4000 Autohelm Clutch Wheel. This is a 3D printed part made from solid PETG plastic. This is one clutch wheel and does not include any bearings or other parts. This was originally made and printed to replace a broken clutch wheel on a boat. It is a great fit.

This has a 15mm bore, please check the wheel you are replacing as this is different to the belt twnsioning wheel that has a 12mm bore.

Please note that as a 3D printed item it has visible layer lines when viewed closely. This does not effect the ability to do its job.

If you are unhappy about anything please message me before leaving negative feedback so I can endeavour to solve the situation.
