Frequently Asked Questions

What hydraulic cylinder parts fit a Case 450 dozer?

Broken Tractor carries blade angle cylinders, blade lift cylinder rods, gland nuts, glands, pistons, seal kits and service tools for the Case 450, 450B and 450C dozers. Examples include the Blade Hydraulic Angle Cylinder (SKU 140146A1), the Blade Lift Cylinder Rod (SKU G34348), the Gland Nut (SKU 1543003C1) and the Dozer Tilt Cylinder Gland (SKU 1543021C1). Many of these parts also fit the Case 550 dozer series.

Which seal kit fits the blade lift cylinder on a Case 450 dozer?

The Blade Lift Cylinder Seal Kit (SKU 1543250C1) fits the Case 450B, 450C and 550 dozers, along with select Case 450 and 350B dozers. It is made in the USA by Bulldog or Hercules Hydraulics. Because fitment on the original 450 is limited to select machines, match the part number on your cylinder before ordering.

How do I find the right hydraulic cylinder seal kit for my Case 450 dozer?

Fitment depends on your model and on which cylinder you are rebuilding, and some early 450 kits are matched by the part number stamped on the cylinder tube. For example, Seal Kit SKU 1543273C1 fits Case 450 dozers with the tube stamped G101232, as well as the 450B, 450C, 550, 550E and 550G. If you cannot read the stamping or are unsure which kit you need, call (800) 909-7060 and the parts team can help confirm fitment.

Should I replace the seals or the whole cylinder on a leaking Case 450 dozer?

A leaking cylinder can often be fixed with a seal kit, which is the most common repair for Case 450, 450B and 450C blade cylinders. If the rod, piston or gland is damaged, Broken Tractor also offers those parts individually, including the Blade Lift Cylinder Rod (SKU G34348) and the Made in USA Replacement Piston (SKU G100438) for the blade angle cylinder. When the cylinder is too worn to rebuild, a complete Blade Hydraulic Angle Cylinder (SKU 140146A1) is available for the 450, 450B and 450C.

What tools do I need to rebuild a Case 450 dozer hydraulic cylinder?

Broken Tractor offers the Case Hydraulic Spanner Wrench for Cylinder Repair (SKU CAS-1456A), which fits Case dozers, and the Hydraulic Gland Seal Installation Tool Kit (SKU CAS-1457) for installing gland seals. Using the right tools helps you remove the gland and seat the new seals without damaging them.
