Caterpillar Overhaul Kit

Caterpillar overhaul kits from Fab Heavy Parts provide aftermarket replacement components for diesel engine rebuilds in compatible construction and industrial equipment. This collection includes engine rebuild kits and overhaul gasket sets, with listings for selected engines such as C3.3, C3.3B, C3.8, C7.1, 3054, 3054B, 3064, and 3304.

Depending on the individual kit, contents may include pistons, piston rings, cylinder liners, main bearings, rod bearings, thrust bearings, valves, valve guides, valve seats, and gaskets. These components serve different roles in the engine’s cylinder assembly, rotating assembly, valvetrain, and sealing system. Check each product’s contents carefully, as included parts and quantities vary.

Before ordering, confirm your engine model, equipment model, serial number, and relevant original part numbers. Compare the listed piston and bearing sizes with your rebuild requirements. Several kits contain semi-finished cylinder liners that require additional machining, so review the product notes with your engine rebuilder before purchasing.

Browse the collection, compare kit contents and listed applications, and select the replacement overhaul kit suited to your engine rebuild.
