Frequently Asked Questions

Which equalizer beam fits a Cat D6N dozer?

The equalizer beam SKU 8E8789 fits the Cat D6N XL, D6N LGP, D6N FTC and D6N D/S, along with the D5H XL, D6M, D6M XL, D6XL and D6M LGP. If you run a D4H XL, D5M XL or D5N XL, the correct beam is SKU 8E8955. Match the part number on your old beam or confirm your exact model and configuration before ordering.

What equalizer pins and bushings fit a Cat D4H?

For the Cat D4H, Broken Tractor offers the center equalizer pin SKU 6Y6886, the equalizer beam end pin SKU 8G3733, the center bushing SKU 7P7858 and the end bushing SKU 9M1328. That covers the main pivot points of the beam, so you can replace the pins and bushings together. The D4H XL uses beam assembly SKU 8E8955, so confirm whether your machine is a standard D4H or an XL.

Are XL and LGP equalizer beam parts interchangeable on a Cat dozer?

No. XL and LGP variants should not be treated as interchangeable, so confirm your blade and undercarriage setup before ordering. Some pins, such as center pin SKU 109-0367 and end pin SKU 109-0377, are listed for both the D6MXL and D6N LGP, while other parts fit only one configuration. Always check the fitment list on each part against your exact model.

Which equalizer end bushing fits a Cat D6T?

The equalizer end bushing SKU 9M1328 fits the Cat D6T. It also fits the D3B, D3C, D4, D4H, D5H, D5M, D5N, D6K, D6K2, D6R-III, D7 and D7E. For a D5H XL or D5H LGP, use end bushing SKU 8G4189 instead.

Can I replace just the equalizer pins and bushings instead of the whole beam on a Cat dozer?

Yes. Broken Tractor carries complete equalizer beam assemblies as well as individual center pins, end pins, center bushings and end bushings, so you can replace only the pivot components if that is all your machine needs. Fitment depends on model and configuration, so match the part number from your old part or call (800) 909-7060 to confirm with the parts team.
