The major cause of clutch failure is excessive heat. Excessive heat generated between the flywheel, driven discs, intermediate plate and pressure plate can cause the metal to flow and the material to be destroyed. If this occurs, the clutch can burst which can cause property damage, serious bodily injury or death. In order to prevent clutch failure resulting from excessive heat: 1. Do not exceed recommended vehicle loads. 2. The clutch should only be used for the recommended applications. 3. Drivers should be properly trained in starting, shifting and operation of the clutch. 4. Drivers should report erratic clutch operation as soon as possible to permit maintenance personnel to inspect, adjust or lubricate as required. 5. The removal and installation procedure described for each component may vary for your vehicle. For Solo and Heavy-Duty ECA clutches only, install shipping bolts before removing clutch assembly from the flywheel.

The sling and spreader bar should be adjusted so the lifting hooks are vertical to prevent bending the lifter brackets. To ensure proper weight distribution, all provided lifter brackets must be used. NOTICE: A spreader bar must be used at all times in conjunction with the front and rear lifter brackets to lift the EGR engine to ensure that no engine damage will result. The brackets are designed to lift vertically. 1. Remove the engine from the vehicle.
A 4-year-old boy was brought to the emergency department with a long history of constipation and recent onset of abdominal pain. His mother stated that he did not have diarrhea, vomiting, or fever, but noted that “his belly is getting hard.” He had a small bowel movement 2 days previously. On the day of presentation, he woke up with abdominal pain. The patient previously had been in good health and had regularly seen his pediatric primary care physician. He had never had surgery or an illness requiring hospitalization. Physical Examination On examination, the following vital signs were obtained: oral temperature, 98.5°F; heart rate, 145 bpm; respiratory rate, 30 breaths/min; blood pressure, 108/59 mm Hg. He was pale and appeared to be uncomfortable due to the abdominal pain. The abdominal examination revealed a large mass in the right side of his abdomen. The mass was firm and slightly tender. He also had guarding. He had bilaterally descended testicles and no evidence of inguinal hernias. His musculoskeletal and neurologic examinations showed normal results, and skin examination revealed decreased turgor and coolness of peripheral extremities, with no rashes, bruising, or petechiae.
Abdominal pain is the most common complaint seen in emergency departments in the United States and one of the 10 most common complaints in family medicine outpatient settings. The most common causes of abdominal pain are discussed here, with special attention given to the acute abdomen and recurrent abdominal pain. The term acute abdomen is medical jargon that refers to any acute condition within the abdomen that requires immediate medical or surgical attention. Acute abdominal pain may be of nonabdominal origin and does not always require surgery. The majority of patients who consult a physician about abdominal pain do not have an acute abdomen, although the chief complaint may have a sudden onset. In studies involving analysis of large series of patients presenting to emergency departments with acute abdominal pain, nonspecific abdominal pain (NSAP) was the most common diagnosis. Most patients with this symptom probably have gastroenteritis. The common causes of abdominal pain are gastroenteritis, gastritis, peptic ulcer disease, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), dysmenorrhea, salpingitis, appendicitis, cholecystitis, cholelithiasis, intestinal obstruction, mesenteric adenitis, diverticulitis, pancreatitis, ureterolithiasis, incarcerated hernias, gas entrapment syndromes, and ischemic bowel disease (particularly in the elderly). All of these conditions can manifest as an acute or sudden onset of abdominal pain, many can cause recurrent abdominal pain, and a few require surgical intervention. Any acute abdominal condition requires the physician to make an early, precise diagnosis, because prognosis often depends on prompt initiation of therapy, particularly surgical treatment. The more serious the problem, the more urgent the need for an accurate diagnosis.

Packaging and dilemmas in packaging development By Professor Roland ten Klooster CurTec International offers packaging and packaging knowhow for industrial and distribution applications in the pharmaceutical, speciality chemicals and other industries. We strongly believe in offering added value through quality, functionality, user-friendliness and design. Added value can be found in many other aspects than just the tangible product. To select or develop the optimal packaging it is essential to have a complete insight in all these aspects. Through the publishing of a series of White Papers on Packaging we hope to make a small contribution to the packaging issues you are confronted with. The CurTec Team White paper | Packaging and dilemmas in packaging development Over 3.5 billion are lost to the cost of packaging, packaging should add value and not be seen as waste’, says Professor ten Klooster. Better packaging can lead to a better product, he claims, which is why he suggests revising and professionalizing the development processes.
Consumer product packaging designers are faced with conflicting requirements throughout the development process. Good pack aesthetics are vital for the success of the product, whilst unit costs must be minimized and suitability for stacking and transportation maintained. This paper describes, by example, how design optimization technology can be used to enhance the design process. It is demonstrated that the technology can be employed to provide clear design information for the pack designers, facilitating definition of an attractive shape incorporating features to meet the structural and manufacturing requirements whilst minimizing cost. Consumer product packaging designers are faced with conflicting requirements throughout the development process. Good pack aesthetics are vital for the success of the product, whilst unit costs must be minimized and suitability for stacking and transportation maintained. A significant improvement in the design process can be gained if design information can be clearly communicated to the product designers early in the design process. This paper describes how design optimization and advanced CAE can be used to deliver this. The resulting design process facilitates the early definition of an attractive pack shape incorporating features which will meet the structural and cost requirements. The design optimization process requires input in the form of a series of alternative shapes for the pack,...
