4BT references for a defined repair

The 4BT 3.9 cylinder-head example CH64911 is distinct from the 6BT 5.9 head CH64912. The crankshaft and head-gasket examples below give separate starting points for a repair enquiry. A shared B-series name does not make heads or crankshafts interchangeable.

Piston ring set or complete engine requirement?

R-CM01-00 is catalogued for 4BT and 6BT applications. State the piston reference, ring positions and repair size, then specify whether your quantity is per cylinder or for the complete engine. A shared ring reference does not establish the number of sets supplied.

Checking a Cummins 4BT water pump

Send the pump reference, ESN and photos of the drive, mounting face and coolant connections. The pump must be checked individually; a 4BT label or visual resemblance alone is insufficient. Include gaskets, seals or other required items explicitly in the enquiry.

These public catalogue examples help identify a request. Confirm the engine variant, reference, repair size and quantity before ordering; a catalogue entry does not confirm current availability.
