The cummins QSB3.3 cylinder block 3972507 is a cast iron engine block designed for the QSB3.3 diesel engine, used primarily in light industrial and agricultural machinery. It features six cylinder bores with a diameter of 90 mm, a bore spacing of 110 mm, and a deck height of 242 mm. The block includes integrated coolant passages, main bearing caps, and mounting points for the cylinder head, oil pan, and ancillary components. This is a direct replacement for original Cummins units, not a modified or enlarged design.
The block is manufactured from gray cast iron with a minimum tensile strength of 220 MPa, consistent with industry standards for medium-duty diesel blocks. The cylinder walls are honed to a surface finish of 10 to 15 microinches Ra, typical for engine rebuilds. No claims are made about sleeve inserts, nitriding, or coating treatments. The casting includes core plugs and threaded holes for freeze plugs, oil gallery plugs, and sensor fittings as per OEM specification.
This cylinder block is purchased by engine rebuilders, agricultural equipment service centers, and small-scale diesel engine manufacturers in Southeast Asia, Africa, and Latin America. Buyers typically order in quantities of 1 to 10 units for overhaul projects. Trade terms are usually FOB Shanghai or CIF port of destination. Packaging is either original Cummins-style or neutral wooden crate, depending on buyer request. Minimum order quantity is not specified but is commonly one unit for rebuilders.

Sourcing cummins QSB3.3 cylinder block 3972507 from Hubei Goodear Machinery Co., Ltd. - China Import Guide
Before ordering, verify the casting number and part number 3972507 against your engine’s original block. QSB3.3 blocks vary slightly between model years; bore diameter and coolant port locations may differ. Request a photo of the casting marks and compare them with OEM documentation. Confirm the block has not been previously machined or welded.
Lead time is typically 15 to 30 days from China, depending on port schedules. Trade terms are usually FOB Shanghai or CIF destination. Payment is commonly by T/T 30% advance and 70% against copy of bill of lading. Buyers should confirm if the block is packed in a wooden crate with moisture barrier. Insurance is advised for shipments over $3,000.
Quality checks should include measuring bore diameter, checking deck flatness, inspecting for cracks with dye penetrant, and verifying coolant passage integrity. Request a dimensional inspection report if available. The supplier does not provide certification, so buyers may need to send a sample to a third-party lab for material analysis. Retain photos and test records for warranty purposes.
