## Choose the engine family first

Our catalogue examples span cylinder heads, crankshafts, pistons, rings and oil pumps. The 4BT and 6BT pages below separate their product references and ordering details. ISX piston and oil-pump examples are listed here; a family name does not identify every variant.

## Engine identification for a parts enquiry

Send the engine serial number (ESN), full model, CPL if available, and the existing part number. Add a clear data-plate photo when the identification is incomplete. Cummins provides parts lookup by ESN; use that information to identify the required reference before comparing replacements.

## Define the replacement parts order

Separate standard and repair sizes, quantities and set contents. For pistons, state whether rings, pins and circlips are required; for pumps, identify the drive and connections. RigForce confirms the offered reference, availability and quotation contents. Brand names identify applications and do not imply original-brand goods or authorized dealership.

## Part reference examples

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.
