Tecumseh 510145 Crankshaft Seal Lawn Garden Engine

Product Description

The TECUMSEH 510145 is a crankshaft seal designed as a direct OEM replacement for Tecumseh small engines commonly found in lawn and garden power equipment. The crankshaft seal sits at the junction between the crankshaft and the engine block, preventing oil from migrating out along the crankshaft journal and keeping contaminants from entering the crankcase. A failed or leaking crankshaft seal leads to oil loss, external leaks, and potential engine damage if left unaddressed. This part is installed by small engine technicians and knowledgeable equipment service professionals as part of routine engine rebuilds or targeted seal replacement procedures.

The 510145 crankshaft seal is intended for use in Tecumseh-powered lawn and garden equipment including walk-behind mowers, riding mowers, tillers, snow blowers, and similar outdoor power equipment fitted with Tecumseh small engines. Replacement is typically performed when visible oil seepage appears at the crankshaft exit point on the engine block, or as a precautionary measure during a full engine overhaul to restore like-new sealing performance.

Designed as an OEM-style replacement crankshaft seal for Tecumseh small engines used in lawn and garden power equipment. Consult the Tecumseh parts lookup or equipment service manual using part number 510145 to confirm fitment for a specific engine model.

Installation Notes

Crankshaft seal replacement is performed by small engine technicians familiar with engine disassembly procedures. Before beginning work, disconnect the spark plug wire and drain engine oil to eliminate ignition and fluid hazards. Use a seal driver or appropriately sized socket to press the new seal squarely into its bore without cocking or distorting the lip. Refill engine oil to the manufacturer-specified level before returning the equipment to service.
