Description
Overview:
This crankshaft oil seal (25 x 41.2 x 8 mm) is designed for Yanmar L‐series single‐cylinder diesel engines, including the L48N5SJ1 and L48. It sits at the crankshaft exit to retain engine oil and keep dust and debris out, helping maintain stable oil pressure and reducing wear. Built from durable, oil‐resistant elastomer with a reinforced construction, the seal uses a radial lip design with an internal garter spring for consistent contact against the shaft. It is suitable for compact construction and garden machinery powered by Yanmar engines, where long service life and reliable sealing matter. Dimensions: 25 mm x 41.2 mm x 8 mm (approximately 1.00 in x 1.62 in x 0.31 in).
Key Features:
- Precise sizing: 25 mm shaft, 41.2 mm housing bore, 8 mm width (≈ 1.00 in x 1.62 in x 0.31 in) for a proper press‐fit
- Radial lip with internal garter spring maintains steady sealing pressure on the crankshaft
- Oil‐ and heat‐resistant elastomer construction for dependable performance in demanding use
- Helps prevent oil leakage and ingress of dust or slurry, protecting bearings and crank surfaces
- Suitable for routine servicing and full engine overhauls on Yanmar L‐series units
- Stable fitment for mixer‐spec and other industrial applications where vibration is common
- Supports efficient running, reduced downtime, and extended engine life when replaced at service intervals
- Straightforward installation using standard seal drivers and correct lubrication
Typical Applications:
Used on Yanmar L‐series engines fitted to plate compactors, mixers, generators, pressure washers, pumps, light plant, and agricultural or landscaping equipment. Ideal when addressing oil weeps at the crank, during rebuilds, or preventative maintenance to restore reliable sealing in daily site or workshop use.
