MS660 Chainsaw Complete Rubber Kit (29 Items Per Set)
Comprehensive Sealing & AV Component Set for STIHL 066 & MS660 Professional Saws
The MS660 Complete Rubber Kit (29 Items Per Set) is a comprehensive rebuild solution addressing all rubber components on the STIHL MS660, MS650, and 066 professional chainsaws. This parts kit includes fuel and impulse lines, anti-vibration (AV) mounts, grommets, O-rings, buffer elements, and various seals needed to restore a saw to reliable working condition.
Technical Profiles & Materials
Comprehensive 29-Piece Restoration – The set includes a complete assortment of rubber components for MS660, 066, and MS650 saws, replacing fuel and impulse lines, AV mounts, grommets, O-rings, and sealing elements. This all-in-one solution prevents sourcing individual parts and ensures all wear-prone rubber is renewed simultaneously.
Superior Vibration Damping – High-quality elastomeric rubber mounts (also known as AV rubbers or annular buffers) are custom-engineered to reduce vibration transmission from the engine to the handles. This feature reduces operator fatigue during extended use and protects internal components from mechanical stress.
Fuel System Integrity – Includes replacement fuel pipes, impulse line, and inlet manifold, which are critical for maintaining proper fuel delivery and crankcase pressure in the 2-stroke engine. Deteriorated rubber lines are a primary cause of lean running conditions and engine damage.

FAQ
Q: How do I confirm this rubber kit fits my MS660?
A:Check your chainsaw model and serial number. This kit fits STIHL MS660, MS650, 066, 064, and MS640 models. The kit includes components for both standard and Magnum/Arctic variants. Users performing a rebuild on an older 066 with new cases may need to verify oil seal compatibility.
Q: What components are included in a 29-piece rubber kit?
A: The kit includes AV rubbers, fuel pipes, impulse line, inlet manifold, chain case rubber, fuel and oil cap seals, grommets, O-rings, and buffers. Some variations may also include annular buffers and screws based on the specific aftermarket manufacturer.
Q: Is it worth replacing all rubber components at once?
A: Yes. All rubber components on a chainsaw age at a similar rate due to fuel exposure, heat, and vibration. Replacing them all together ensures all wear-prone seals are renewed simultaneously, preventing premature failure of new components. Professional rebuild kits combine these components for this reason.
