- lf-locking nuts provide tight connections that will not loosen under vibrations.
- They meet critical specifications as to strength, corrosion resistance, and heat-resistant temperatures.
- New selflocking nuts must be used each time components are installed. There are two general types of self-locking nuts.
- They are the all metal nuts and the metal nuts with a nonmetallic insert to provide the locking action.
- The elastic stop and the nonmetallic insert lock nut are examples of the nonmetallic insert type.
- All metal self-locking nuts are constructed either of two ways. The threads in the load-carrying portion of the nut that is out of phase with the threads in the locking portion is one way.
- The second way is with a saw-cut top portion with a pinched-in thread. The locking action of these types depends upon the resiliency of the metal.
The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators
