Description
Overview:
The Insulation Wall Assembly 504 72 47-01 is a genuine Husqvarna component designed for petrol chainsaws such as the Husqvarna 135 and 140. It forms a thermal barrier between hot engine areas and adjacent parts to reduce heat transfer. This helps protect the carburettor, intake tract, plastic shrouds, wiring, and fuel lines from heat soak that can affect running quality. Made from a durable, heat‐resistant polymer composite, it is shaped to fit the factory mounting points for a secure seal. By maintaining more stable operating temperatures around sensitive components, this part supports consistent performance and helps extend service life, whether the saw is used for routine cutting, pruning, or heavier site work.
Key Features:
- Genuine Husqvarna part for correct fit and compatibility
- Thermal barrier design helps prevent heat soak and vapour lock
- Protects nearby components from heat-related stress and deformation
- Tough, heat-resistant polymer composite for long service life
- Supports smoother running and more stable carburetion in varied conditions
- Precision-moulded to OEM geometry for reliable sealing and alignment
- Suitable for regular maintenance or as a like-for-like replacement during rebuilds
- Helps maintain performance during prolonged cutting or warm weather use
- Straightforward installation with standard hand tools
- Direct replacement for OEM reference 504 72 47-01
Typical Applications:
Used during service or repair of Husqvarna chainsaws when addressing heat-related running issues, replacing damaged internal panels, or completing top-end overhauls. Suitable for professional forestry and landscaping work, grounds maintenance, and DIY tasks where consistent performance and protection of intake and electrical components from engine heat are required.
Also known as:
