Industrial PTO & Clutch - How & Why to Bump a Clutch

Key Points to Consider:

Engagement RPM Matters: All industrial clutches should be engaged under 1000 RPM as recommended by the manufacturer. Lower RPMs will significantly improve clutch life expectancy.

Avoid Slipping the Clutch: Slipping generates heat, which is detrimental to clutch health. Proper engagement techniques are crucial to avoid excess heat buildup.

When Bumping a Clutch Is Necessary: In some applications, especially those with a large inertia of mass to rotate, direct clutch engagement can stall the engine. To prevent this, "bumping" the clutch is required.

How to Bump a Clutch: Bumping involves short partial engagements (typically 2-3 bumps) to start the rotation action without stalling the engine or overheating the clutch. Once enough rotation has begun, a full lock-in engagement can be achieved safely.
