What happens if oil gets spilled on my clutch?
Electromagnetic PTO clutch brakes are used on a variety of outdoor power equipment. Their basic purpose is to transfer engine torque to a rotating cutting blade or other accessory. They are also safety devices by offering braking torque when power is removed from the clutch coil. They are used on zero turn mowers, riding tractors, stump grinders, concrete saws, and other mobile engine powered equipment.
Ogura GT series clutch brakes actuate electrically but transmit torque mechanically. When power is applied to the coil, the clutch engages. The torque is transferred to the pulley or hub output by mechanical means. The friction surfaces are steel. The coefficient of friction is relatively high. If oil were to get into the contact area, then problems would occur. The oil will cause reduced coefficient of friction. This would result in the clutch slipping upon an attempted engagement. Slipping will cause heat and this is the worst enemy of a clutch. Slipping can cause galling or micro-welding at the friction surfaces. It is even possible that the clutch will lock up due to permanent damage. Slipping can also cause rapid build up of heat which can melt the bearing seals and wire insulation. Once the bearings or coil are damaged, the clutch will never work properly again. So, it is important to keep the clutch free of any grease or oil.
>The PTO clutch brakes are also safety devices. When powered is removed from the coil, the clutch disengages, and the brake engages. The brake engages to bring the cutting blade or tool to a quicker stop for safety. If the clutch brake is contaminated with grease or oil, the brake torque will be reduced. The contact surface of the brake is steel-on-steel. This means that safety will be compromised, and the clutch should be replaced immediately.

Ogura GT series PTO clutch-brakes are made in a variety of configurations and typically mount on gas and diesel engines rated up to 40 HP. Bore sizes match the typical engine shaft sizes. Pulley sizes can vary based on machine requirements. Some have hub outputs to mount your own pulley, sprocket or coupling half. Clutch torque is rated up to 400 lb-ft on the larger units. These clutches typically operate on 12 or 24VDC.
