Import Detroit Diesel Engine Parts — Buy in wholesale FOB from Supplier in India

Nass Engineering Services supplies genuine replacement components for Detroit Diesel engines, including pistons, fuel injectors, cylinder head gaskets, and valve stem seals. These parts are manufactured to match OEM dimensional tolerances and material specifications, ensuring direct fitment in Series 60, 4000, and 71 engines. The supplier sources materials from certified Indian foundries and machining units that comply with ASTM and SAE standards for cast iron and alloy steel used in high-stress engine components.

Typical piston diameters range from 102 mm to 152 mm with a compression height tolerance of ±0.05 mm, and fuel injectors are built to meet Detroit Diesel’s 1998-2010 nozzle flow rate standards. Gaskets are produced using multi-layer steel (MLS) with silicone coating, a common industry practice for high-pressure combustion chambers. Surface finishes on crankshaft journals and connecting rods follow standard ground-and-polished profiles, not aftermarket rough finishes. These are not reconditioned or remanufactured parts; they are newly forged or cast components.

These engine parts are primarily purchased by fleet operators in India, Southeast Asia, and Africa who maintain heavy-duty trucks, marine vessels, and stationary power generators. Buyers typically order in batches of 10 to 50 units depending on maintenance cycles. Packaging is in anti-corrosion sealed boxes with part-number labels and batch codes. Trade terms include FOB Mumbai and CIF ports in Kenya, Bangladesh, and Nigeria. Lead times vary by component availability and require direct confirmation with the supplier.

Nass Engineering Services operates from Navi Mumbai, Maharashtra, with a registered address in the NBC Complex. The supplier is classified as a harbor-tier entity on the platform, indicating verified business registration and physical address. There is no public data on years in operation, workforce size, or export volume. The listing does not claim certifications, revenue, or client names. The company appears to function as a parts distributor sourcing from local manufacturers rather than a factory owner.

No factory photos, production lines, or quality control processes are disclosed. The supplier has no recorded response rate or average response time, suggesting limited engagement with buyer inquiries. Buyers should treat this as a sourcing intermediary and verify component origins directly. The supplier does not state whether parts are OEM, aftermarket, or remanufactured, leaving material and process details to be confirmed through request for documentation.
