Product Details
Product Overview
This high-performance Cylinder Head Gasket is specifically designed for Libohaier (Liebherr) D924 and D926 diesel engines, serving as a critical sealing component for the engine’s combustion chamber. The gasket ensures a reliable seal between the cylinder head and engine block, preventing compression leaks and coolant/oil contamination. Engineered to OEM specifications, this replacement part carries the original part numbers 4980359, 9277662, and 9277606, providing a direct fit for your heavy-duty machinery.
As a core component in engine overhaul and repair kits, this cylinder head gasket is essential for maintaining optimal compression ratios and preventing exhaust gas leakage. Whether used in construction equipment, industrial machinery, agricultural tractors, or marine generators, this gasket is manufactured to withstand high thermal and mechanical stresses typical of diesel engine operation. The part is suitable for both standard rebuilds and emergency repairs on Libohaier-powered equipment.
Key Features & Benefits
Precision Fitment: Manufactured to match OEM dimensions for Libohaier D924 and D926 engine blocks, ensuring no modification required during installation.
High-Temperature Resistance: Constructed from multi-layer steel (MLS) or composite materials designed to withstand extreme combustion chamber temperatures up to 300°C (572°F).
Compression Seal Integrity: Features silicone bead or rubber coating on critical sealing surfaces to prevent blow-by and maintain cylinder compression within factory specifications.
Corrosion Protection: Treated with anti-corrosion coating to resist coolant chemicals and combustion byproducts, extending service life beyond standard repair intervals.
Direct OEM Replacement: Cross-references to genuine part numbers 4980359, 9277662, and 9277606, eliminating guesswork during parts procurement.
Comprehensive Warranty: Backed by a 6-month warranty against manufacturing defects, with online technical support available post-warranty.

FAQ
Q1: How do I confirm this gasket fits my specific Libohaier D924 engine? A: Verify your engine’s serial number and existing gasket part number. The D924 engine family includes several variants (TI-E, L4, naturally aspirated). Our part numbers 4980359, 9277662, and 9277606 cover the majority of D924 and D926 applications. If your engine has a different gasket thickness (e.g., 1.3mm vs 1.5mm), measure the compressed thickness of your old gasket. We recommend ordering a thickness gauge set for accurate replacement.
Q2: Can I install this gasket without removing the cylinder head? A: No. The cylinder head gasket is a critical sealing component that requires complete removal of the cylinder head for proper installation. You must follow the engine manufacturer’s torque specifications and tightening sequence (typically 4-stage tightening process). We recommend replacing all head bolts simultaneously and checking cylinder head flatness with a straightedge before installation.
Q3: What maintenance intervals should I expect for this gasket? A: Under normal operating conditions (standard load, proper coolant maintenance), this gasket typically lasts 4,000-6,000 operating hours. However, in severe applications (high load cycles, poor coolant quality, overheating events), replacement may be required sooner. Watch for symptoms like coolant loss without external leaks, white exhaust smoke (coolant burning), or oil contamination (milky appearance). We recommend annual gasket inspection during major service intervals.
