3406 Overhaul Kit For CAT 3406B 3406C 3406E Engine Repair Kit

Complete in-frame overhaul kit for the CAT 3406 engine family, covering 3406, 3406B, 3406C and 3406E versions. 14.6L inline 6-cylinder, includes pistons, liners, rings, bearings and gaskets. Matched by engine serial prefix. Fully inspected before shipment.

The Caterpillar 3406 is one of the most trusted heavy diesel engines ever built, powering North American highway trucks, large excavators and mining equipment for decades, and many of those machines are still earning their keep today. Because the 3406 family spans mechanical and electronic versions, the right overhaul kit depends on the exact engine configuration: the 3406B and 3406C use mechanically governed fuel systems while the 3406E is fully electronic, and the piston, liner and gasket specification follows the engine serial prefix. This kit is matched to your engine before shipment, so an in-frame rebuild restores compression, oil control and power with predictable parts cost, keeping a proven engine working for another full service life.
