Description

PERKINS INDUSTRIAL ENGINES:
• Perkins 1206E-E66TTA/1206E-E70TTA 1206 Series 6.6-7.0L Diesel (2010-present)

CATERPILLAR EXCAVATORS:
• Caterpillar 320E/323F/326F C6.6/C7.1 Diesel (2010-2020)


IMPORTANT:
Perkins T407192 is the valve cover gasket for the Perkins 1206E series engine (1206E-E66TTA/1206E-E70TTA). Cat equivalent is 256-7704. This fits the Tier 4 generation engines (2010+) used in Cat 320E/323F/326F excavators and other applications. Do NOT confuse with earlier 1106D valve cover gaskets — the 1206E is a different engine architecture with different gasket dimensions.

Failure symptoms: oil seeping from the valve cover, oil on the exhaust manifold causing smoke. The rubber gasket degrades from heat cycling. When replacing, inspect the valve cover for warping and clean both mating surfaces thoroughly. Perkins 1206E = Cat C6.6/C7.1 Tier 4 — all part numbers cross-reference directly between Perkins and Cat.

⚠️ Cross-ref: Perkins T407192 = Cat 256-7704. Verify 1206E engine, not 1106D.
