HOW TO CHOOSE THE RIGHT DIESEL ENGINE REPAIR KIT
Cummins has a wide range of engine models, and there will be differences in the structure and component sizes of different engine models. Therefore, when choosing a Cummins overhaul kit, you must specify the specific model of your engine, such as 4BT, 6BT, 6CT, QSX15, etc., and then choose an overhaul kit that is fully compatible with it.
The pistons, piston rings, cylinder liners, valve oil seals and other parts included in the overhaul kit for each model are customized according to the design requirements of that engine model. If selected incorrectly, they may not be installed or may not work properly after installation.
EPID supplies Cummins original quality parts, OEM parts, and Aftermarket parts. Our high-quality diesel engine rebuild kits are the most reliable in terms of quality, performance and price, which can guarantee the performance and reliability of the engine after overhaul.

Why 6BT pumps fail and how to choose a replacement
Water and oil pumps on 6BT engines usually fail from seal wear (coolant or oil weeping at the weep hole), bearing noise, or impeller erosion from abrasive coolant. A leaking seal that is ignored takes the bearing with it within a few hundred hours. Check the pulley alignment and belt tension at the same time — misalignment is a common cause of repeat failure.
Our 6BT pumps use OEM-quality bearings and mechanical seals, and each unit is flow tested before packing.
