Description
Overview:
This non-genuine replacement head gasket is designed for Yanmar single‐cylinder diesel engines, including the L60AE and L70AE. It seals the joint between the cylinder head and engine block to maintain compression and to keep oil and coolant passages separate, helping the engine run efficiently and reliably. Made from high‐temperature gasket materials suitable for diesel service, it is precision cut for accurate alignment of cylinder, coolant and oil ports. Used during top‐end repairs or rebuilds, it is a practical choice for compactors, generators, pumps and other light plant powered by Yanmar L‐series engines. It is a direct replacement for OEM reference 114870-01340 and is built to match the required thickness and profile for dependable sealing when installed to a clean, flat mating surface.
Key Features:
- Non-genuine replacement part for Yanmar L60AE and L70AE engines
- Helps prevent loss of compression and cross‐leaks between oil, coolant and combustion gases
- Durable construction for high temperature and pressure typical of small diesel engines
- Accurate port geometry for proper coolant and oil flow alignment
- Consistent thickness for even clamping load across the head and block
- Direct replacement for OEM 114870-01340 to simplify selection
- Straightforward fit with standard hand tools when surfaces are clean and true
- Suitable for engines used in compactors, generators, pumps and other light construction equipment
Typical Applications:
Used during head gasket replacement after overheating, signs of oil/coolant mixing, loss of compression, or as part of a routine top‐end overhaul. Common on small plant and machinery powered by Yanmar L‐series engines, such as plate compactors, site generators, water pumps, pressure washers and cement mixers. Suitable for workshop repairs and on‐site maintenance where reliable sealing and minimal downtime are important.
