## Long description

Crankshaft oil seal PRO model YTOP4317 15×26×5 mm for petrol brush cutter/top431s is a rotary shaft seal designed for small two-stroke engines used in petrol brush cutters. The seal creates a tight barrier around the engine crankshaft to prevent oil and fuel leakage, maintain proper lubrication and reduce contamination of the crankcase and surrounding components. It is intended for repair and maintenance of garden power tools where a precise fit and reliable sealing performance are required.
Advantages
This crankshaft oil seal is manufactured to match the 15×26×5 mm dimensions commonly used in compact brush cutter engines, providing a secure fit and consistent sealing pressure. The seal material offers resistance to oil, fuel and normal operating temperatures of two-stroke engines, helping to extend engine life by reducing leaks and contamination. Its compact design simplifies installation in confined engine housings and supports routine maintenance and engine rebuilds.
Suitable for (tasks / use cases)
Repair and replacement of crankshaft seals in petrol brush cutters with matching shaft and bore dimensions
Routine maintenance and engine overhaul of small two-stroke garden power tools

Key specifications
Inner diameter: 15 mm
Outer diameter: 26 mm
Width / thickness: 5 mm
Seal type: rotary crankshaft oil seal
Compatible engine type: small two-stroke petrol engines
Typical application: petrol brush cutters / handheld garden tools
How to use
Before replacement, ensure the engine is cool and free of fuel vapors. Drain oil or fuel as required and remove surrounding components to access the crankshaft area. Carefully extract the old seal without damaging the crankshaft journal or housing bore. Clean the mating surfaces and check shaft and bore for wear or scoring; replace components if necessary. Align the new 15×26×5 mm seal squarely with the housing bore and press it in evenly using an appropriate sized driver or seal installation tool until it is flush with the housing face. Reassemble components, refill oil or fuel as specified by the engine manufacturer, and run the engine briefly to verify there are no leaks.
Usage recommendations
Use only seals with matching inner and outer diameters and proper material compatibility for two-stroke engines. Inspect the crankshaft journal and housing bore for wear before installation. Apply a thin film of engine oil to the seal lip and shaft to aid installation and initial operation. Avoid hammering directly on the seal; use a suitable installation tool to prevent seal damage or misalignment.
