Electromagnetic Clutches OGURA INDUSTRIAL CORP Mobile Clutches [78 to 237 Nm (58 to 175 lb-ft ) torque] Installation Procedure 1. This installation assumes the most common form of mounting, mounting to a pump bracket or direct mounting to a pump face. The pump can be hydraulic, water, a vacuum, or a compressor. These clutches consist of two major subassemblies: the ﬁeld and the rotor/armature assembly. 2. Attach the ﬁeld to the customer-supplied mounting bracket or pump face. Use the four ¼” cap screws supplied with the clutch. Tighten each screw to 10.85 Nm (8ft-lbs), taking care not to strip...
