Description
Overview:
This Cylinder Head Gasket is a genuine Yanmar component for small diesel engines, engineered to seal the joint between the cylinder head and engine block on the Yanmar L48AE and L40AE. Built from durable, heat- and pressure-resistant gasket materials, it maintains combustion pressure and separates oil, coolant, and gases to prevent cross-leaks. A precise profile and bolt-hole pattern support correct alignment during assembly, helping protect the engine from loss of compression, overheating, and contamination. Specified to Yanmar's standards and referenced by part number 114770-01340, it is suitable for routine maintenance, repairs, and full rebuilds on compact plant, agricultural, and garden machinery powered by these engines. Using the correct gasket helps restore performance and supports reliable cold and hot running in demanding site and outdoor conditions.
Key Features:
- Genuine Yanmar part number 114770-01340 for assured compatibility
- Accurate fit for L48AE and L40AE engines to maintain compression
- Helps prevent coolant and oil leaks across the head-to-block joint

- Correct port layout and fire-ring location for consistent sealing
- Clean bolt-hole pattern for straightforward positioning
- Supports reliable starting, power output, and fuel efficiency
- Suitable for servicing, overhauls, and rebuilds with standard tools
- Helps reduce risk of mixing fluids and subsequent engine damage
- Durable construction aimed at long service life in tough conditions
- Meets manufacturer specifications for thickness and sealing performance
Typical Applications:
