The J I CASE 220 service manual encompasses a range of appendices designed to support technicians with precise terminology, accurate assembly guidance, and official servicemethods. In the glossary of terms, you will encounter standardized nomenclature used across CASE equipment to ensure clear communication among maintenance personnel. The definitions cover common torque values, fastener types, lubrication specifications, and safety-related terms that frequently appear in service procedures. Understanding these terms reduces the potential for misinterpretation during repairs and helps technicians follow procedures exactly as intended by the manufacturer. Familiarity with the glossary also aids in ordering the correct replacement parts and documenting service work consistently in maintenance logs.
Torque reference charts provide critical data for selecting proper fastener torque levels based on bolt size, material, lubrication, and the engaged surface area. These charts help prevent overtightening, which can damage threads and mating surfaces, as well as undertightening, which can lead to component looseness and failures in operation. For the J I CASE 220, torque values are listed in relation to specific assemblies such as the engine mounting, linkage joints, hydraulic components, and chassis hardware. It is essential to follow the sequence of torque application, particularly for multi-bolt flanges or bearing caps, to avoid distortion and ensure even pressure distribution. When performing torque checks, practitioners should use calibrated torque wrenches and consider temperature and oil condition, as these factors can influence effective torque during assembly and service.
The warranty and service policy section outlines the conditions under which CASE equipment remains eligible for coverage, including service intervals, authorized repair procedures, and required documentation. This section typically specifies what constitutes proper maintenance, what parts are covered, and how claims should be submitted to the manufacturer or authorized dealers. Technicians should become familiar with the warranty terms before planning extensive repairs, to avoid non-coverable tasks or misinterpretation of coverage limitations. The policy also describes approved service channels, the need for genuine CASE parts, and the process for obtaining service manuals, update bulletins, and warranty claim forms. Proper adherence to these policies supports customer confidence and helps ensure that repairs meet official standards and safety criteria.
