Tecumseh 788083 Oil Seal 5/8 Inch

Product Description

The TECUMSEH 788083 is an OEM oil seal designed to prevent lubricant leakage at the crankshaft or output shaft on Tecumseh small engines. Measuring 5/8 inch, this seal maintains a tight barrier between rotating shaft surfaces and the engine housing, protecting internal components from contamination and keeping oil where it belongs. It is a direct replacement part sourced from the original manufacturer, making it a reliable choice for restoring a leaking or worn seal to factory specification. Licensed technicians and qualified service professionals handle this repair as part of routine engine maintenance.

This oil seal is used on Tecumseh small engines commonly found in lawn and garden equipment, including walk-behind lawn mowers, snow blowers, tillers, and similar power equipment. The 5/8 inch shaft size is a common dimension across several Tecumseh engine families. Service typically arises during engine rebuilds, crankshaft replacements, or when oil leakage is traced to the front or rear main seal location.

Key Features

• OEM Tecumseh replacement oil seal for accurate fitment and proper sealing
• 5/8 inch shaft diameter matches common Tecumseh engine crankshaft dimensions
• Prevents oil leakage and protects engine internals from external contamination
• Direct replacement simplifies sourcing during engine rebuild or seal replacement service

Compatibility

Designed as an OEM-style replacement oil seal for Tecumseh small engines used in lawn and garden power equipment applications.

Installation Notes

Installation should be performed by a qualified small engine technician. Drain engine oil and disconnect the spark plug before beginning any seal replacement work. Use an appropriate seal driver or a flat, smooth press tool to seat the seal evenly without distorting the sealing lip. Avoid using sharp tools near the seal lip, as damage will cause immediate leakage after reassembly.
