## 6BT piston and cylinder-head selection

P-CM004-00 is a piston example catalogued for 6BT 5.9; CH64912 is a separate cylinder-head example for that model designation. Send the ESN, full engine identification and existing references. Piston crown, pin and ring-groove details and head assembly contents still require confirmation.

## Lubrication parts and repair quantities

The PP-221194 oil-pump example is recorded for 6BT. Confirm drive, oil passages and the components included. For R-CM16-00 piston rings, state the required size and whether quantities refer to one cylinder or the engine; do not infer a complete rebuild kit from these separate examples.

## Checking a Cummins 6BT water pump

Water-pump selection needs the specific pump reference, mounting and connection details. Include the installation details for marine, industrial or vehicle use. Do not substitute a 4BT pump or another 6BT variant without confirming the individual reference.
