Premium Engine Overhaul Rebuild Kits for Caterpillar C3.8 Series

Restore the power and long-term reliability of your equipment with a comprehensive overhaul rebuild kit for the Caterpillar C3.8 engine. This 3.8L, 4-cylinder engine is the primary powerplant for a wide range of heavy-duty Caterpillar machinery, including D2 and D3 series compact track loaders (299D2, 299D3, 297D2), skid steers (272D, 236D), and compact wheel loaders (910K).

Engineered to meet or exceed original factory specifications, these kits provide a complete set of internal rotating components and seals. Most kits feature semi-finished cylinder liners, allowing for custom machining to ensure a perfect fit with the engine block. Utilizing a verified rebuild kit ensures the 3.9-inch (100 mm) bore and 4.7-inch (120 mm) stroke maintain the precise compression needed for intensive earthmoving and material handling operations.
