Frequently Asked Questions

What is a pin replacement kit used for on a 590 Super L?

A pin kit replaces worn pins and bushings at a specific pivot joint on your Case 590 backhoe. Worn pins cause slop, clunking, and poor bucket or boom control. We carry kits for the coupler, dipper, boom, swing tower, stabilizer, and loader frame connections.

How do I know which pin kit fits my Case 590 backhoe?

Match the kit to the joint you are servicing and confirm your model, since the 590 Turbo, 590SL, and 590SM share some kits and differ on others. Comparing the part number to your machine is the most reliable method. Our parts team can help you match at (800) 909-7060.

Do you have a tool to remove and install the bushings?

Yes, we offer a steel bushing driver removal and installation tool that works on backhoes, loaders, excavators, and dozers. It makes seating new bushings much easier than improvised methods.

What kits cover the boom and swing tower on a 590SM?

We carry pin and bushing kits for the boom to swing tower, boom cylinder to swing tower, and dipper cylinder to boom joints on 590 Super L and 590 Super M machines. Each is sold for its specific pivot point.
