Midwest Industrial Sales is the leading supplier for Caterpillar articulated haul truck parts. We understand machine downtime, which is why we stock all types of components to cover the large variety of Cat trucks ranging from the D350D to the later model Cat 740.

CATERPILLAR D400D / D350D | CAT D400E / D350E

Large Selection of Components and Wear Parts

We specialize in components and wear parts for the Cat D400D/E / D350D/E series of articulated trucks. We commonly have rebuilt exchange components such as transmission and drop box assemblies, hoist cylinders, rear ride struts, differentials, and final drive assemblies. Replacement / Aftermarket parts are available to save you money when replacing bearings, pins, bushings, and other common wear parts.



New Hoist Cylinders and Front Ride Cylinders

Being a supplier for parts and components for the Cat articulated truck series for 10+ years gives us a competitive advantage in our market. We have come to learn of common components and strive to better meet our customer's needs efficiently and effectively. If you have Cat 740 Haul trucks in your fleet, you probably already know that the front ride cylinders and hoist rams become unrepairable after failure. We have both of these components ready and waiting for immediate delivery. As part of our continued effort to provide unparalleled service to our clients we are adding commonly replaced components to our product line on a regular basis.
