Frequently Asked Questions

How do I know if I need a left-hand or right-hand engine side frame for my John Deere dozer?

The left-hand and right-hand engine side frames are sold separately and are not interchangeable, so you need to identify the correct side for your machine. For example, on the 350 series we carry the Engine Side Frame Left (SKU AT36817) and Engine Side Frame Right (SKU AT36818). If you are unsure which side you need, match the part number to your machine or confirm with our parts team at (800) 909-7060.

Which engine side frame fits a John Deere 450C dozer?

For the John Deere 450, 450B, and 450C dozers we carry the Engine Side Frame Left (SKU AT59690) and Engine Side Frame Right (SKU AT59689). These are specific to that group, as the later 450D and up use different frames. Match the part number to your machine to confirm the correct side and series.

What is the difference between the standard and long track engine side frames for 450D through 555B dozers?

Broken Tractor offers both standard and long track versions for the later series machines. The Engine Side Frame Right SKU AT81313 is the long track version for 450D, 450E, 455D, 455E, 550, 550B, 555, and 555B dozers, while SKU AT69006 covers the standard right-hand fitment for the same models. Confirm whether your machine is standard or long track before ordering, or check with our parts team.

Do you carry frame spacers and reinforcement plates for John Deere 450 to 555 dozers?

Yes, we carry the Frame Spacer (SKU T34389) and the Frame Rail Reinforcement Plate (SKU T34391) for John Deere 450 through 555B dozers. Both fit the 450, 450B, 450C, 450D, 450E, 455D, 455E, 550, 550B, 555, and 555B machines. These support parts work alongside the engine side frame rails.

Are the John Deere 350 series engine side frames the same as the 450 series?

No, the 350 series and 450 series use different engine side frames that are not interchangeable. The 350, 350B, 350C, 350D, and 355D use SKU AT36817 (left) and AT36818 (right), while the 450 series uses separate part numbers. Always match the part number to your model and serial number to confirm fitment.
