Description
The Milling Machine Overload Clutch Trip Lever B74-96 is an essential safety component used in the feed transmission system of vertical and turret milling machines. It activates the overload release mechanism when excessive torque or sudden load occurs, preventing damage to the feed gears, motor, and drive components.
Engineered from hardened alloy steel for robustness and long life, the trip lever ensures smooth feed operation and dependable overload protection. Its precision-machined profile guarantees accurate interaction with the overload clutch assembly, delivering consistent performance even under heavy-duty machining loads.
Usage:
- Used to engage and disengage the overload clutch mechanism in vertical turret milling machines During Auto feed
- Automatically trips the feed system when excessive load or jamming occurs to protect gears and feed components.
- Works as part of the safety cut-off assembly to prevent damage to the auto-feed gearbox.
- Ensures smooth operation by resetting and reactivating the auto-feed after the overload condition is cleared.
- Ideal for routine maintenance and replacement during feed system servicing or overload clutch repairs.

More questions buyers ask
What is an overload clutch trip lever on a milling machine?
It is a safety component that automatically disengages the feed system when excessive torque or jamming occurs, protecting the machine's gears and motor.
Which milling machine models is this B7496 lever compatible with?
This lever is designed for M2, M3, M4, and M5 series ram turret milling machines.
Why is the trip lever made of hardened alloy steel?
Hardened alloy steel provides the necessary strength and wear resistance to withstand constant mechanical stress and ensure long-term reliability.
Can I replace the trip lever myself?
Yes, it is a standard replacement part for maintenance, but ensure the machine is powered off and follow your service manual for proper installation.
What happens if the overload clutch fails to trip?
If the clutch fails to trip, the feed system may suffer severe damage, including stripped gears or motor burnout, due to excessive load.
How do I know if my trip lever is worn out?
Signs include inconsistent feed engagement, failure to trip during minor jams, or visible wear and deformation on the lever's contact surfaces.
Is this part compatible with Bridgeport-style mills?
Yes, this B7496 model is a standard replacement for many Bridgeport-style ram turret milling machines.
Does this part come with a warranty?
Pentagon provides standard industrial warranty coverage; please check the specific invoice details for your purchase.
What is the weight and material of this trip lever?
It weighs 1.5 kg and is constructed from high-strength hardened alloy steel.
How does the trip lever protect the feed system?
It acts as a mechanical fuse that physically disconnects the feed drive when resistance exceeds the factory-set threshold.
Who should choose the B7496 Overload Clutch Trip Lever?
This part is ideal for workshop owners and maintenance technicians managing M2, M3, M4, or M5 ram turret milling machines who need a reliable, high-durability replacement for their feed safety system.
Is there a difference between this and generic trip levers?
Pentagon's version is precision-machined for exact OEM-spec fitment, ensuring reliable clutch release compared to lower-quality generic alternatives.
