DETROIT DIESEL 4-71 Engine Block For Sale (Part 5117439M)
About This Detroit Diesel 4-71 Engine Block
This is a good, used engine block for the Detroit Diesel 4-71, carrying part number 5117439M. The block is the engine's main structural casting, housing the cylinders, crankshaft supports, and internal oil and coolant passages. Cracks, damaged bores, failed threads, deck-surface problems, or main-bearing wear may require machining or replacement during a rebuild. Block castings and machining details can vary within an engine family, so matching the application, casting, and any available part number is essential before purchase. Review the inspection photos and compare the original block's configuration rather than assuming every version will interchange. The part is inspected and tested before it ships, identified by its stock number (319581), and backed by included warranty coverage. Freight ships nationwide, quoted to your delivery ZIP. Use the page photos and listed details to compare it carefully with the component being replaced before purchase. Have your engine's year, make, model, and application ready and call (800) 696-5459 to confirm fitment before ordering.
