Commercial marine fishing is a difficult profession performed in a variety of harsh environments. For days on end, some boats and their crews are at sea, working 24 hours a day. Reliability of their equipment is a must, and even when things go wrong there needs to be a back-up plan in place. Downtime is not an option - Time is money.

The Ogura MMC Series clutches are designed for use in extreme conditions like those seen on a lobster or shrimp boat. The clutch is used to engage and disengage the hydraulic pumps that lower or raise the nets or traps when hauling in the catch. While the clutch is a highly reliable component when applied properly, there are still times when things go wrong, or the clutch simply wears out.

If the clutch will not engage or can't drive the load, the MMC features a "limp home" feature that allows the clutch to drive the pump without power. Two threaded holes in both the armature and rotor allow the operator to insert a bolt that draws and locks the two plates together. This provides a mechanical lockup to operate the nets or traps and continue fishing with a minimal loss of time and money.

All MMC clutches feature the limp home design and range in torque from 200 to 1500 lbft. A variety of bore sizes and pulley options are available. Most larger clutches operate via an inline drive and the clutch hub is fitted with a bolt pattern that matches common driveshaft couplings.

• Reduced engine load during cold weather starts
• Increased operational life of pumps and other driven equipment
• Fuel and energy savings
• Safety and convenience (remote starting)
