Engine Piston for Deutz FL912/FL913 Air-Cooled Diesel Engines SKU: QT2002346217

When an engine piston wears out, cracks, or develops ring groove damage, your Deutz air-cooled diesel loses power, burns oil, and develops that distinctive knock that signals expensive internal damage is coming. This replacement piston restores proper compression and smooth operation to your FL912 or FL913 engine before minor wear becomes a major overhaul.

Why OEM Quality Matters

• Precision-cast and machined to exact tolerances for proper clearances and long life
• Heat-resistant alloy withstands the extreme temperatures of air-cooled operation
• Correct pin boss design ensures proper connecting rod alignment
• Ring groove spacing matches original specifications for optimal sealing

Worn pistons don't just lose power—they contaminate your oil with combustion gases and metal particles, accelerating wear throughout the engine. If you've been adding oil more frequently or notice excessive blowby, this piston addresses the root cause rather than just treating symptoms. S&H Parts has been helping customers keep their Deutz engines running strong since 1969.
