Frequently Asked Questions

What bushing fits a Komatsu GD655-3A grader?

Bushing SKU 07177-05030 is listed to fit the Komatsu GD655-3A, along with the GD675-3A, GD621A and GD625A. Bushing SKU 07177-05530 is listed for the GD655 and GD675. Because fitment can change between versions of the same model, match the part number on your old bushing or call (800) 909-7060 to confirm with our parts team before ordering.

Which bushing fits a Komatsu GD725 motor grader?

Bushing SKU 07177-05530 is listed to fit the Komatsu GD725, as well as the GD655, GD675 and GD705. If you are not sure which bushing your machine uses, compare it against your existing part number before you order.

What bushing fits a Komatsu GD505A or GD405A grader?

Bushing SKU 07177-05030 covers the Komatsu GD405 through GD705 series and specifically lists the GD505A. Broken Tractor's fitment data also includes the GD405A in the GD400 series. Match your existing part number to be sure you get the right bushing for your machine.

Where are pins and bushings used on a Komatsu motor grader?

On Komatsu GD series graders, pins and bushings sit at the main wear points, including the blade circle, the drawbar pivot and the articulation joint. These joints move under load all day, so the bushings wear over time and need to be replaced to keep the blade and frame working tight.

Can I buy single Komatsu grader bushings or do they come in kits?

Broken Tractor offers both individual bushings and multi-piece bushing kits for Komatsu graders from the GD405A through the GD725. You can replace one worn bushing or do a larger rebuild of a joint, depending on how much wear you find.
