Frequently Asked Questions

What size cutting edge kit fits a Case 450C dozer blade?

It depends on your blade width. Broken Tractor carries an 88 inch blade cutting edge kit (CS-450-CEK) for the Case 450, 450B and 450C, and a 96 inch blade kit (CS-550E-CEK) that fits the 450, 450B, 450C, 550, 550E and 550G. LGP machines with a 104 inch blade, including the 450B LGP, 450C LGP, 550E LGP and 550G LGP, use kit CS-450LGP-CEK. Measure your blade before ordering to get the right kit.

Does the Case 450 blade angle cylinder fit a Case 550G?

Yes, the blade hydraulic angle cylinder (140146A1) fits the Case 450, 450B, 450C, 550, 550E and 550G. The blade tilt cylinder (G101228) is listed for the 450, 450B, 450C and 550 only, so check your model before ordering a tilt cylinder.

What pins hold the blade on a Case 550G dozer?

Broken Tractor carries the main pins for the Case 550G blade, including the blade main center pin (D34789), angle cylinder pin (D34795), tilt cylinder pin (D34796), lift cylinder rod pin (D46467) and lift cylinder to trunnion pin (D24508). We also offer the rear C-frame mounting pin (R50774) and the angle cylinder to leveling beam pin (D44881), which fits only the 550E and 550G. Match the part number on your old pin to be sure you get the correct one.

Which blade frame bracket fits a Case 450C Long Track dozer?

The blade frame mounting bracket R55861 fits the Case 450C LT along with the 550, 550E and 550G. The blade frame bracket R47535 fits the standard 450C only and excludes Long Track machines. If you are unsure which version you have, call (800) 909-7060 with your model and serial number.

Will a Case 550 blade C-frame fit a Case 450?

The blade C-frame (241962A1) is listed to fit the Case 450B, 450C, 550, 550E and 550G, but not the original 450. Owners of an original 450 should confirm fitment by part number before ordering. For C-frame wear points, we also carry the C-frame bracket bushing (D30930) and center blade U-frame bushing (D33023), which fit the 450 through 550G.
