Crankshaft Seal for Generator TOG2000K (part YAP2R227) — No name brand

Replacement crankshaft seal designed for TOG2000K series portable generators. This circular oil seal fits the generator crankshaft to prevent oil leakage between the engine block and rotating shaft, helping to maintain proper lubrication and engine performance. The part is intended for maintenance and repair of TOG2000K units where the original seal shows wear, hardening, or damage that allows oil to escape or contaminants to enter the engine.

Advantages

The seal is manufactured from oil-resistant elastomer and features a metal reinforcement ring that ensures dimensional stability and reliable sealing under radial shaft movement. Its design minimizes friction and reduces heat generation at the shaft interface, which contributes to longer service intervals and reduced risk of oil contamination. The seal's profile provides a tight contact lip that maintains a consistent barrier against oil leaks while accommodating normal shaft runout.

Suitable for

• Repair of TOG2000K portable generator engines
• Replacement of worn or hardened crankshaft seals
• Preventive maintenance during engine overhaul
• Field service where oil leakage from the crankshaft is observed

Key specifications

• Function: crankshaft oil seal for rotary shaft sealing
• Material: oil-resistant elastomer sealing lip with metal reinforcement
• Design: single-lip sealing profile with spring-loaded contact (where applicable)
• Operating conditions: suitable for typical small-generator engine temperatures and lubricants
• Compatibility: designed to match dimensional and sealing requirements of TOG2000K series generators

How to use

Drain engine oil and clean the area around the crankshaft housing before removing the old seal. Use appropriate tools to extract the worn seal without damaging the shaft or bore. Inspect the crankshaft journal and housing bore for wear or burrs, clean and, if necessary, polish the shaft surface gently. Press the new crankshaft seal evenly into the bore until it sits flush using a seal driver or a suitably sized socket to avoid deforming the sealing lip. Refill engine oil to the specified level and run the engine briefly to verify the absence of leaks.

Usage recommendations

When installing the replacement seal, apply a thin film of compatible engine oil to the sealing lip and shaft to ensure initial lubrication. Avoid using excessive force during installation and verify shaft surface condition to prevent premature seal failure. Follow the generator manufacturer's service intervals and use the appropriate lubricant type and viscosity.
