Description
Overview:
This crank seal is a direct-fit oil seal for Yanmar single‐cylinder diesel engines, engineered to keep engine oil in and dirt out at the crankshaft exit. Built with a tough, oil‐resistant elastomer and a metal‐reinforced, rubber‐coated outer case, it uses a spring‐loaded sealing lip to maintain consistent contact under heat, vibration and load. It is suitable for Yanmar L90AE and L100AE engines commonly found in compact construction plant, generators, pumps and agricultural equipment. The precise fit helps restore sealing performance on worn units and reduces the risk of leaks that can lead to clutch contamination, reduced lubrication and premature wear. OEM reference 24423‐355008 helps confirm correct identification when replacing a like‐for‐like part.
Key Features:
- Engineered for Yanmar L‐series diesel engines for reliable sealing at the crankshaft
- Oil‐resistant elastomer with spring‐energised lip for stable sealing over time
- Metal‐reinforced, rubber‐coated outer diameter for secure housing retention
- Helps prevent oil leaks and ingress of dust or slurry, protecting bearings and internals
- Maintains oil pressure at the seal location to support overall engine longevity
- Precise dimensions for L90AE/L100AE fitment, reducing installation time and rework
- Withstands heat, vibration and axial movement typical of compact diesel engines
- Identified by OEM reference 24423‐355008 for easy cross‐checking
- Suitable for preventative maintenance as well as like‐for‐like replacement
- Compatible with standard seal drivers or appropriately sized sockets for fitting
Typical Applications:
Used on Yanmar L‐series engines powering compactors, generators, water pumps, cement mixers, pressure washers and small agricultural or garden machinery. Ideal when refurbishing engines that show oil weep at the crank end, during clutch or flywheel service, or as part of routine overhauls to minimise downtime on site.
