187-1315 Full Overhaul Gasket Kit (Steel Plate Head Gasket) for Caterpillar C9 Engine CAT 330D 336D

187-1315 Caterpillar C9 Full Overhaul Gasket Kit

The 187-1315 Full Overhaul Gasket Kit is engineered specifically for Caterpillar C9 (C-9 ACERT) 6-cylinder diesel engines operating in heavy-duty construction excavators such as the CAT E330C, E330D, and E336D. Designed to withstand extreme combustion pressures and thermal cycling, this complete major overhaul set features a reinforced steel-plate core cylinder head gasket with high-density graphite composite facing, ensuring superior sealing between the cylinder block and head during full engine rebuilds.

Key Features & Manufacturing Advantages

• Steel Plate + Graphite Composite Head Gasket: Combines a high-tensile steel plate core with precision-bonded graphite facing and fire-ring reinforcement to prevent blowouts, coolant leaks, and oil cross-contamination.

• OEM-Grade Elastomers (Viton® & PTFE): Includes white PTFE cylinder liner crevice seals, heat-resistant red/black Viton® O-rings, and metal-cased crankshaft oil seals rated for continuous high-temperature operation.

• One-Piece Molded Oil Pan Gasket: Supplied on a rigid anti-warp backing board to guarantee flat, distortion-free installation on the C9 oil pan rail.

• Complete Major Overhaul Coverage: Consolidates upper cylinder head gaskets, central oil cooler seals, and lower engine block gaskets into one organized package to minimize machine downtime.
