Overview – BAD CORE-ENGINE 6BT DR109DC
DR109DC is the cylinder block core used on CUMMINS 6BT engines as the foundation of an engine rebuild, supplied bare without the cylinder head and internal rotating parts. We can supply this engine block core as well as the related rebuild components, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The block is cast to the original 6BT geometry, with the six cylinder bores, main bearing saddles, oil galleries and deck surface machined to the original specification. The bore finish and alignment are matched to the piston and crankshaft build so the rebuilt engine runs true. The block retains the original mounting points for the timing case, oil pan and cylinder head. As an OEM-spec core, it accepts the original 6BT internals without modification.
Applicable Models & Applications
This cylinder block core is used on CUMMINS 6BT engines where the original block is worn or cracked beyond service limits. Typical applications include the 6BT engine family used in trucks, industrial equipment and generator sets. Confirm the block serial number, bore size and deck height against your engine build specification before ordering.
Maintenance & Replacement
An engine block is replaced when the bores are worn beyond limits, the deck is distorted or the galleries are cracked. Before rebuilding, inspect the block for cracks, measure the bores and deck flatness, and check the main bearing alignment. When assembling, clean all galleries, fit the camshaft and crankshaft bearings to the original specification, and torque the main bearing caps in the correct sequence.

Value & Service
A block with the wrong deck height or bore size can ruin an entire rebuild, so we verify DR109DC against the original CUMMINS 6BT specification before dispatch.

Our team will confirm the correct block for your engine serial number before you buy.
