We carry both new and used parts for these older G-series crawler dozers. Match the part number or fitment to your machine to be sure you get the correct component.

Do these 450G, 550G, 650G blade parts fit the 450H, 550H, and 650H dozers?

Some do, but only on early H-series units. Parts like the blade cap bolt (19M7963), pivot ball (T147801), ball socket kit (T180534), and blade cap (T180535) also fit 450H, 550H, and 650H units before serial number 903159. Because fitment depends on serial number, confirm your serial before ordering or call our parts team at (800) 909-7060.

What is included in the complete blade ball pivot kit for a John Deere 550G dozer?

Broken Tractor offers a Complete Blade Ball Pivot Kit (SKU PV5004) that fits the 450G, 550G, and 650G. We also carry the individual pivot components separately, including the blade pivot ball (T147801), ball (T170501), ball shim (T144253), ball socket kit with weld-on gussets (T180534), and blade cap (T180535). If you need only one worn piece, order the individual part; if the whole pivot is worn, the kit covers it.

Which blade face replacement fits a John Deere 650G dozer?

We carry two blade faces for the 650G. The Replacement Blade Face (SKU PV507) fits John Deere 450G, 550G, and 650G, and the 120 inch Wide Dozer Blade Face (SKU PV508) also fits the 450G, 550G, and 650G. Choose based on your blade width and confirm the part matches your machine before ordering.

How do I know if I need the early style main center blade bushing for my 450G?

The Early Style Main Center Blade Bushing (SKU AT157247) fits the 450G, 550G, and 650G and works with the matching spacer (T112826), retainer plate (T124132), and early style main center blade pin (T122600). If your center blade pivot has excessive play or slop at the mounting point, the bushing and pin are common wear items. Match the part numbers to your machine to confirm you have the early style setup.
