The Multiquip HS004900137B Clutch Spring is a genuine OEM component designed for HS62, HS81, HS62A, HS81A, SHS62A, and SHS81A high-speed cut-off saws. Sourced directly from Multiquip, this spring meets the exact tensioning specification required by these handheld saws to engage and disengage the blade clutch correctly. It is a direct-fit replacement that installs into the clutch assembly without modification, restoring proper clutch operation quickly and confidently. If you are chasing clutch slip, premature blade engagement, or inconsistent disengagement, replacing this spring is a logical first step.
Key Features
- OEM Spring Rate Accuracy — Manufactured to the original tension specification, ensuring the clutch engages at the correct RPM threshold — not too early, not too late.
- Direct Clutch Assembly Fit — Designed to seat precisely within the clutch housing of compatible Multiquip and STOW sidewinder cut-off saws, replacing the original spring position for position.
- Broad Sidewinder Saw Compatibility — Fits HS62, HS62A, HS81, HS81A, SHS62A, and SHS81A models, covering both MQ and STOW variants of the high-speed cut-off saw lineup.
- Clutch Engagement Consistency — A correctly tensioned clutch spring keeps blade engagement smooth and controlled, supporting clean, accurate cuts on every pass.
- Operator Safety Relevance — The clutch spring plays a direct role in preventing unintended blade spin at idle. A fatigued or broken spring can cause the blade to drag or engage erratically, posing a real hazard on the cut.
The clutch spring applies the return tension that holds the clutch shoes retracted while the engine is at idle speed. As engine RPM rises, centrifugal force overcomes the spring tension, allowing the clutch shoes to expand outward and engage the drum, which drives the blade. When the spring weakens or breaks, the clutch engagement point drops, meaning the blade may begin spinning at lower RPMs than intended — or fail to disengage fully when the throttle is released. Replacing a worn clutch spring restores the designed engagement RPM and keeps blade behavior predictable and safe.
