Frequently Asked Questions

What transmission clutch parts fit a John Deere 450C dozer?

Broken Tractor carries steel clutch separator plates (SKU R57345) and friction discs (SKU AR94516) that fit the John Deere 450C, along with a rebuilt shuttle pack (SKU AT104145) and a 60 inch shift cable (SKU AT83335). Because clutch stacks can vary by serial number, match the part number to your machine or confirm the fit with our parts team before ordering.

Do you have a rebuilt transmission manifold for the 450 series dozer?

Yes, Broken Tractor offers a rebuilt transmission manifold (SKU AR56620) that fits the 450C, 450D, 450E, 455D, and 455E, as well as the 450B after serial number 142200. If your 450B falls before that serial number break, confirm the correct part with our parts team so you get the right manifold.

What charge pump fits a John Deere 450G dozer transmission?

We carry a torque converter transmission charge pump (SKU AT159747) that fits the John Deere 450G, along with 550G and 650G models. This is the part to look at when the powershift transmission is low on charge pressure.

Is there a transmission disc replacement kit for the 450G dozer?

Yes, Broken Tractor offers a transmission disc replacement kit (SKU AT117908-K) that fits the 450G, 455G, 550G, 555G, and 650G. We also stock the individual metallic drive friction disc (SKU AT117908) and steel clutch plates (SKUs R80813 and R56547) if you only need specific pieces for your rebuild.

What pilot pressure valve fits a John Deere 450J dozer?

The pilot pressure valve SKU AT304671 fits the John Deere 450J and many later J and K series machines. For the 450H generation, we carry a separate pressure control pilot valve (SKU AT220775) that fits the 450H, so match the valve to your exact model.
