FAQ

Q: Is this 106-5122 air compressor a direct bolt-on replacement for my Caterpillar 3412E engine?
A: Yes, this assembly is designed to be a direct replacement for the OEM 106-5122 part. It matches the original mounting points, drive coupling, and air discharge port locations. However, we always recommend comparing the dimensions and mounting pattern with your existing compressor to account for any minor engineering changes in different engine serial number ranges.

Q: Does this compressor come pre-filled with oil, and what maintenance is required before installation?
A: The compressor is shipped dry (without oil) to prevent leakage during transit. Before installation, you must fill the compressor with the correct grade of engine oil as specified in your Caterpillar 3412E service manual. After installation, prime the lubrication system by cranking the engine with the fuel shut-off engaged for 10-15 seconds to ensure the compressor bearings are lubricated before starting.

Q: How do I verify this part will fit my 773E truck if the engine has been rebuilt or modified?
A: The 773E truck typically uses the 3412E engine. For rebuilt engines, the most reliable method is to locate the engine serial number (located on the engine block near the fuel injection pump) and cross-reference it with Caterpillar’s parts database. Additionally, measure the distance between the mounting bolt holes and the diameter of the drive shaft spline on your old compressor to ensure a match with this 106-5122 unit.
