Full engine gasket set (overhaul gasket kit) for the Caterpillar 3066 / S6K / C6.4 diesel engine family (also 3064 / C4.2) — a direct replacement for the original Caterpillar 5I-7797. The set covers the main sealing parts needed for an engine overhaul, typically including: cylinder head gasket(s), intake / exhaust manifold gaskets, valve cover gasket, oil pan gasket, front and rear crankshaft seals, plus assorted O-rings, copper washers and small metal gaskets. It lets you renew all the seals in one go when the engine is stripped for an overhaul.
Overhauls are normally triggered by a blown head gasket, a scored liner, oil / coolant cross-contamination, blow-by, high oil consumption or power loss. Seals should be renewed as a set to avoid re-using old gaskets and re-developing leaks.
Supplied as a complete set (contents depend on the actual kit). Confirm the removed part number and the engine model before ordering; clean all mating faces and check flatness, tighten to the specified torque and sequence, and fit the head gasket the right way up if it is marked.
Note: the exact contents / part count depend on the actual kit - contact us to confirm the exact list.
Key Features
