Stop settling for a standard "rebuild." Choate Performance offers a fully remanufactured Komatsu SAA6D107E Long Block that utilizes the same precision engineering as our high-performance 6.7L Cummins builds. Designed for owner-operators who cannot afford downtime, our engines are built to be smoother, cooler, and more durable than a factory-fresh unit.
The Choate Remanufacturing Process
We treat your industrial engine with the same "Stock is Not an Option" philosophy we use for our 1,000+ HP competition builds:
-
CNC Blueprint Boring: We don't just hone cylinders; we CNC blueprint the block to ensure perfect geometry and alignment.
-
Precision Balancing: All rotating assemblies are weight-matched to within 2 grams. This minimizes vibration: the leading cause of bearing failure in heavy equipment.
-
Torque Plate Honing: We simulate the stress of a torqued cylinder head during the honing process to ensure the most consistent ring seal possible.
-
Upgraded Components: Every engine receives brand-new critical components. We use upgraded valve materials to prevent the high-heat separation common in OEM exhaust valves.
What’s Included:
-
Fully Machined Block & Crankshaft (Ground to 0.0005" or less)
-
New Upgraded Pistons & Rings (Designed to prevent cracking under high boost)
-
New Main, Rod, and Cam Bearings
-
Remanufactured Cylinder Head (New oversized seats and socket plugs)
