Description

CATERPILLAR EXCAVATORS:
• Caterpillar 320E/320F/323F/326F/329F/330F C6.6/C7.1 Diesel (2010-2020)

CATERPILLAR MOTOR GRADERS:
• Caterpillar 120M2 C7.1 7.1L Diesel (2012-2018)


IMPORTANT:
Cat 256-7704 is a valve cover gasket for the Cat C6.6/C7.1 engine (Perkins 1206E series). Perkins equivalent is T407192. This fits the Tier 4 generation engines (2010+) found in Cat 320E/320F/323F/326F and similar excavators and motor graders. Do NOT confuse with earlier C6.6 valve cover gaskets (Cat 317-3064 or 277-5063) which fit the Tier 3 engine — different gasket dimensions.

Failure symptoms: oil seeping from the valve cover, oil on the exhaust manifold causing smoke, oil pooling in the valley between cylinder banks. The rubber gasket degrades from heat cycling over time. When replacing, inspect the valve cover for warping or cracks. Clean the mating surfaces thoroughly — any old gasket residue will prevent proper sealing. Torque bolts evenly per the service manual.

⚠️ Cross-ref: Cat 256-7704 = Perkins T407192. Verify Tier 4 C6.6/C7.1 engine.
