The Shacman X5000 Gasket with OEM number 612630120002 is a precision-engineered sealing component designed to prevent fluid and gas leaks between mating surfaces in heavy-duty diesel engines. This genuine gasket ensures a perfect seal between engine blocks, cylinder heads, manifolds, or other critical joints, maintaining compression and preventing contamination. The 612630120002 gasket is manufactured from high-quality materials such as multi-layer steel (MLS) or fiber-reinforced composite, depending on the application, offering excellent heat resistance, compression recovery, and chemical compatibility with engine oils, coolants, and combustion gases.
Designed specifically for Shacman X5000 engines (WP12, WP13, and ISM series), the OEM gasket features a precisely cut profile, elastomer sealing beads, and reinforced bolt holes to prevent extrusion under high clamping loads. The 612630120002 gasket is 100% laser-cut or die-stamped to exact dimensions, with a surface finish optimized for both smooth and rough flange interfaces. Its advanced coating provides anti-stick properties, allowing for easy removal during future service without damaging mating surfaces.
Aftermarket gaskets often use inferior materials, incorrect thickness, or lack the required sealing beads, leading to leaks, blown gaskets, and engine downtime. Genuine 612630120002 is tested for compression set, thermal cycling, and burst pressure to ensure it withstands temperatures from -40°C to +250°C and pressures up to 30 bar. Each gasket is individually inspected for visual defects, dimensional accuracy, and material integrity before packaging.
Choosing OEM 612630120002 guarantees a leak-free assembly, optimal engine performance, and extended component life. Whether you are replacing a cylinder head gasket, intake manifold gasket, or any other engine sealing application, this genuine Shacman gasket delivers the reliability required for millions of kilometers of heavy-duty operation.
Gaskets are the unsung heroes of engine integrity. A failed gasket leads to oil leaks, coolant loss, compression loss, or even catastrophic engine failure. OEM 612630120002 is designed using finite element analysis to match the clamping force distribution of the specific joint. The MLS construction uses multiple steel layers with viton rubber coatings to accommodate surface irregularities and thermal expansion cycles.
Aftermarket gaskets often compress permanently under heat, losing sealability. Genuine 612630120002 maintains its thickness and sealing force even after thousands of thermal cycles, ensuring that bolts retain torque. The integrated sealing beads are precisely shaped to concentrate pressure exactly where needed, preventing leaks around combustion chambers and coolant passages.
Before installation, thoroughly clean both mating surfaces using a scraper and non-abrasive solvent. Remove all old gasket material and ensure surfaces are dry and free of oil. Do not use sealants unless specified by Shacman; the genuine gasket has an integrated sealing layer that requires no additional compound. Place the gasket over the dowel pins and install the component (cylinder head, manifold, cover).
Torque bolts in the recommended sequence and in 2-3 stages to final specification. For cylinder head applications, follow the angle-torque procedure. After running the engine to operating temperature, allow it to cool and re-torque bolts if specified in the service manual. Never reuse a gasket once it has been compressed; always install a new OEM 612630120002 for each assembly.
Each 612630120002 gasket is manufactured in a clean-room environment. Steel coils are precision-slitted, coated with rubber, and then stamped using progressive dies. For composite gaskets, fiber sheets are laser-cut to exact contours. Silicone sealing beads are applied via robotic dispensing. Each gasket is then 100% vision-inspected for bead continuity, hole alignment, and surface defects.
Random samples are subjected to a hot compression test at 250°C for 500 hours, measuring thickness loss (<5%). A leak test on a pressurized fixture confirms zero leakage at 15 bar. All gaskets are individually sealed in anti-corrosion packaging to prevent moisture absorption before use.
OEM 612630120002 replaces Shacman part numbers 612630120001, 612600012345, and DZ13241821015. It is compatible with Shacman X5000 engines, including WP12.460, WP13.550, and ISM11E5. Also fits X3000 and X6000 series where the same gasket is specified. Always verify the exact application before ordering, as gaskets are application-specific.
This gasket is commonly used for intake manifold, exhaust manifold, timing cover, or oil pan sealing. For cylinder head applications, use the dedicated cylinder head gasket set. Always consult the Shacman parts catalog to confirm the correct gasket for your repair. When replacing, also inspect the mating flanges for warpage (exceeding 0.1 mm per 100 mm requires resurfacing).
Fleet experience shows that genuine 612630120002 gaskets outlast the engine’s first life. Many trucks have operated over 1,000,000 km with the original gasket still sealing perfectly. Aftermarket gaskets often fail within 200,000 km, causing costly repairs. By choosing OEM, you eliminate repeat failures and maximize uptime.
Shacman’s validation includes a 1,000-hour hot-shaker test: the gasket is installed in a joint subjected to 200°C while vibrating at 10g RMS. The gasket shows no leakage after 1,000 hours. A pressure pulsation test cycles from 0 to 30 bar at 1 Hz for 500,000 cycles – no blow-by. A thermal shock test from -40°C to +120°C (1,000 cycles) confirms the rubber coating remains intact.
In field trials across 500 engines, the OEM gasket achieved a 99.8% success rate with zero seal-related failures up to 1.2 million km. By choosing genuine 612630120002, you secure your Shacman X5000 engine against leaks, contamination, and premature wear, ensuring the lowest total cost of ownership.
