Lift cylinders, tilt cylinders, and hydraulic cylinder tubes for Caterpillar 938 series wheel loaders and tool carriers.

What's In This Category

Lift Cylinder Groups

Lift cylinder group (2549037) for the 938H, plus the reference lift cylinder group (1287678) covering the 938F, 938G, M315D, M316D, and M318D. These raise and lower the loader lift arms.

Tilt Cylinder Groups

Tilt cylinder group (1377855) for the 938F, 938G, and 938G II, plus the group (3461093) shared with the 323E L and 324D. These curl the bucket for digging and dumping.

Hydraulic Cylinder Tubes

Replacement cylinder tube (1287674) for the 938F, 938G, and 938G II. Replace the tube when the bore is scored but the rod and gland are still serviceable.

Fitment Tip

The 938 changed cylinders between the F/G and H generations, and some of its groups cross over to the M-series wheeled excavators that share hydraulic components. Match your model suffix and the casting number stamped on the cylinder when rebuilding. The serial number is on the left (highway) side of the machine behind the front tire. Call us with your serial and cylinder number and we'll confirm the right part.

Frequently Asked Questions

Which lift cylinder fits my Cat 938H versus 938G?

The 938H uses lift cylinder group 2549037, while the 938F and 938G use the reference group 1287678 (which also covers the M315D, M316D, and M318D excavators). They don't interchange, so confirm your exact model and serial number before ordering.

Does the 938 tilt cylinder fit other Cat machines?

The 3461093 tilt cylinder group is shared between the 938H and the 323E L and 324D excavators that use the same hydraulic components. The 1377855 tilt group fits the 938F, 938G, and 938G II. Confirm by serial number and casting number, since visually similar cylinders can differ in stroke.

Can I replace just the cylinder tube on my Cat 938?

Yes. The cylinder tube 1287674 fits the 938F, 938G, and 938G II. If the bore is scored but the rod, gland, and piston are still good, replacing just the tube saves money over a complete cylinder group. Inspect the rod and gland first to confirm they're reusable.

Where is the serial number on a Cat 938 wheel loader?

On the 938, the serial number is on the left (highway) side of the machine behind the front tire. Pre-2001 machines use an 8-digit serial; 2001-and-newer machines use a 17-digit VIN. You need this number, plus the cylinder casting number, to order the correct cylinder or tube.

Not sure which cylinder or tube fits your machine? Call or text us at (800) 909-7060 or submit a parts request and we'll match it to your serial number.
