The Hy-Dash Nabtesco GM18 and GM21 final drive is commonly found on Komatsu Kobelco New Holland and Daewoo 13 tonne excavators and a few others besides.

These units are available in a variety of ratios and speeds depending on the application. We stock genuine original Hy-Dash Nabtesco units and two other suitable aftermarket brands.

We consider our aftermarket units to be as good as the genuine Hy-Dash Nabtesco unit however for some people only the original article is acceptable. It is worth noting that whilst a unit for one brand of excavator can be aftermarket it is often original equipment for another.
