1. Full set matched exclusively for 3D84-1 engine, all required sealing accessories integrated for one-time overhaul replacement.
2. Anti-burst graphite cylinder head gasket, withstand high temperature and high pressure inside the cylinder, effectively avoid cylinder gasket blowing failure.
3. High toughness fiber paper gaskets resist corrosion by diesel and engine oil, not easy to soften and deform under long-term high temperature environment.
4. Precision die-cut bolt holes and outlines, direct installation without trimming, greatly shorten maintenance time.

This full overhaul gasket set is customized for Komatsu 3D84-1 3-cylinder small diesel engine, widely applied on Komatsu miniature construction machinery. It covers all sealing positions needed for engine disassembly and maintenance, solving faults such as cylinder pressure drop, overheating, oil seepage, water leakage and gas blow-by caused by aging original gaskets. All rubber seals adopt nitrile rubber material with excellent anti-aging performance, each gasket set is strictly inspected for flatness, hole position accuracy and compression resistance before delivery to ensure stable sealing performance.

We supply parts for Kubota, Cummi ns, CAT, Perkins, Yanmar, Isuzu, Komatsu, Mitsubishi, Hino, Nissan, Vo lvo, Deutz, Doosan, Daewoo, John Dee re, Scania, Hyundai, JCB etc.

A: They belong to different iterations of the 3D84 series engine, the outline of cylinder head gasket, valve cover gasket and manifold mounting holes are inconsistent, cannot be cross-used, must select the corresponding model according to the engine code.

A: Thoroughly clean the residual old gasket and dirt on cylinder block and cylinder head surface; tighten cylinder head bolts diagonally step by step in accordance with standard torque; replace all oil seals and O-rings synchronously to prevent secondary disassembly.

A: During engine major overhaul, cylinder head disassembly repair, solving coolant mixing with engine oil, exhaust white smoke, external oil leakage and power decline failures.
