Description
Overview:
This head gasket is a direct replacement for the Yanmar L90AE diesel engine. It sits between the cylinder head and engine block to create a gas‐tight and fluid‐tight seal, helping to maintain compression while keeping oil and coolant in their correct passages. Built from durable, heat‐resistant gasket materials suitable for high combustion pressures, it supports reliable running and long service life. The L90AE engine is commonly used across compact construction and garden machinery, including generators, water pumps, light plant, and similar equipment. Using the correct OEM-referenced gasket helps prevent cross‐leaks, overheating, and loss of performance, and ensures the engine can be reassembled to the manufacturer's tolerances for dependable daily use.
Key Features:
- Designed specifically for Yanmar L90AE engines for accurate fit and sealing
- Heat and pressure resistant construction for dependable performance under load
- Precision cut to align combustion openings and oil/coolant passages correctly
- Helps restore compression and stable running after top‐end service
- Consistent thickness supports correct torque retention and clamp load
- Direct replacement using OEM reference 114970-01340 / 11497001340
- Aids in preventing oil, coolant, and combustion gas leaks
- Straightforward fitment for reduced downtime when rebuilding the top end
Typical Applications:
Used during engine overhauls, top‐end rebuilds, or when addressing symptoms such as loss of compression, oil or coolant cross‐contamination, external leaks, or overheating. Suitable for Yanmar L90AE engines powering compact construction and garden machinery, including generators, pumps, mixers, light plant, and similar equipment in workshops, hire fleets, and site maintenance.
