🔧 ANOTHER BIG MACK BACK ON THE ROAD! 🔧
We had the pleasure of bringing this big Mack Super-Liner back to life after a failed liner shim brought the Cummins ISX to a grinding halt.
With coolant in the sump and polished liners, it was time to give this engine the attention it deserved. But this wasn’t just any rebuild… this was an IDS rebuild! 💪
🔩 THE IDS UPGRADE – STAINLESS STEEL LINER SHIMS
As part of the rebuild, we upgraded to our stainless steel liner shims and machined the block counterbores to achieve maximum liner protrusion.
As you can see in the photos, our stainless steel shims provide a greater contact surface area than the standard shims. They cover the counterbore ledge more effectively and fit tighter around the liner, providing a larger, more consistent seating surface between the liner, shim and engine block.
It’s all about getting the details right, improving the quality of the build and delivering a result we’re proud to put our name on.
At Ingrey Diesel Services, we believe in doing the job right, using quality parts and delivering workmanship you can depend on.
