YX C189 MD500E Main Shaft Set

Purchased as spare for use as needed.

Perfect fit.

Purchased spare to have on hand when needed. Good value.

perfect fit factory part

... But when you bend it - you may have broken the lower jesus bolt. There's no jesus bolt with the replacement, and I can't find that bolt anywhere in the parts listings... and it's tiny. Good grief.

The part fit perfectly. I needed a main shaft after crashing my helicopter, causing the main shaft to band. This part was a direct replacement..
