Products Description
FS38/FS55 Brush Cutter Gasket Set – Complete Engine Sealing Kit
Comprehensive Gasket Replacement for Stihl FS38, FS55 & Compatible Trimmers
This gasket set provides all the essential sealing components required for engine maintenance and repair on Stihl FS38, FS55, and compatible brushcutters. The gaskets form the critical seals between the carburetor, cylinder, and crankcase, preventing air leaks, maintaining proper compression, and ensuring the engine runs reliably. Over time, gaskets can become brittle, compressed, or damaged from heat, vibration, and fuel exposure, leading to hard starting, erratic idling, and loss of power. This comprehensive kit allows you to replace all wear-prone sealing components in a single service operation, restoring the engine to proper operating condition.

Products Application
Full Engine Overhaul
When performing a complete engine rebuild or cylinder replacement on FS38/FS55 brushcutters, this gasket set provides all necessary sealing components. Replacing all gaskets simultaneously ensures the engine maintains proper compression and crankcase pressure, preventing performance issues and extending engine life.
Carburetor Service
When removing the carburetor for cleaning, repair, or replacement, the carburetor mounting gasket must be renewed to prevent air leaks. A damaged or reused gasket can cause hard starting, erratic idling, and lean running conditions that may lead to engine seizure. This set includes the correct carburetor gasket for a proper seal.
Exhaust System Maintenance
The exhaust gasket should be replaced whenever the muffler is removed during servicing. A worn exhaust gasket can allow hot gases to escape, reducing engine performance and posing a safety risk. This gasket set includes the exhaust gasket to ensure a complete seal.

FAQ
Q: How do I confirm this gasket set fits my brushcutter?
A:Check your machine model number on the housing. This gasket set is compatible with Stihl FS38, FS45, FS46, FS55, FS55R, FC55, HL45, and KM55 models. The OEM reference for the complete set is 4140 007 1062.
Q: What are the symptoms of a failed gasket on a brushcutter?
A: Common symptoms include hard starting, erratic idling, engine surging, loss of power, and fuel or exhaust leaks. A failed cylinder base gasket can cause loss of compression, while a failed carburetor gasket can allow air leaks that cause lean running conditions and potential engine damage.
Q: Can I reuse old gaskets when servicing the engine?
A: It is not recommended to reuse old gaskets. Once removed, gaskets are often compressed, deformed, or damaged, and may not provide a proper seal. Reusing old gaskets can lead to air leaks, fuel leaks, and poor engine performance. Always replace gaskets with new components during engine service.
