This SAE Recommended Practice establishes equipment and procedures for the evaluation of the effectiveness and other performance characteristics of spark arresters or turbochargers used on the exhaust system of large engines normally used in a railroad locomotive, stationary power plant, and other similar applications. This document does not cover applications requiring flame arresting, exhaust gas cooling, or isolation from explosive gases. Two test methods are presented: a laboratory test using ambient air (cold test) and an engine test using exhaust gases (hot test). The hot test is preferred. Arresters tested by the provisions of this document can be expected to perform as tested when tilted no more than 45 degrees from their normal position. Test results from a spark arrester or turbocharger evaluated by the hot test can be applied to different engines of similar design, provided the data shows it to be effective in the applicable flow ranges.

This SAE Recommended Practice is intended to outline basic nomenclature for axle designs in common use for automotive drives. Over a period of years, there have been many different designs; however, for the purpose of this report, only the most common designs have been selected and only their general construction is illustrated to show the nomenclature of the various parts.

This SAE Recommended Practice defines radial lip force for shaft seals. The principle of lip force measurement is described and the types of radial force measuring devices are discussed. A type of radial force measuring device and procedure for use is recommended.

To measure the performance characteristics of Continuously Variable Transmissions (CVT). It outlines dynamometer tests that cover the range of operation and provides a method of presenting the test data. This procedure must be followed with similar test facilities so that results obtained from different laboratories are comparable.

The purpose of this guideline is to provide the essential design considerations for the metal “V” belt variator used in continuously variable transmissions. Information from SAE papers, transmission manufacturers, and component manufacturers is provided to aid engineers in understanding the function and design methodology of the major components within the variator system. Recommended design practices are given based on current practices.

Because of the intense focus on CAFE and fuel emission standards, optimization of the automobile drivetrain is imperative. In light of this, component efficiencies have become an important factor in the drivetrain decision-making process. It has therefore become necessary to develop a universal standard to judge transmission efficiency. This SAE Recommended Practice specifies the dynamometer test procedure which maps a manual transmission’s efficiency. The document is separated into two parts. The first compares input and output torque throughout a specified input speed range in order to determine “in-gear” transmission efficiency. The second procedure measures parasitic losses experienced while in neutral at nominal idling speeds and also churning losses while in gear. The application of this document is intended for passenger car and light truck. All references to transmissions throughout this document include transaxles.

This SAE Recommended Practice is intended as a guide to the use of radial lip type seals. It has been prepared from existing literature, which includes standards, specifications, and catalog data of both oil seal producers and users and includes generally accepted information and data. The main reason for the preparation of the document is to make standard information available in one document to the users of oil seals.

This SAE Recommended Practice defines the minimum internal dimensions for clutch housings to provide adequate clearance for single and two plate spring loaded clutches. Consult SAE J617c (June, 1976) for housing flange dimensions. Consult SAE J618 JUN80 and J619 JUN80 for spring loaded clutch flywheel dimensions F and G and other dimensional data. Table 1 provides housing minimum internal dimensions for single and two flange spring loaded clutches.

This recommended practice applies to nomenclature of turbo-charger parts and terminology of performance. Modifying adjectives are omitted in some cases for the sake of simplicity. However, it is considered good practice to use such adjectives when they add to clarity and understanding.

This recommended practice is intended to provide a uniform test procedure for flywheel assemblies to determine the rotative speeds at which they will either burst or withstand a specified limiting speed.

This SAE Recommended Practice defines the minimum internal dimensions for clutch housings to provide adequate clearance for single and two plate spring loaded clutches. Consult SAE J617c (June, 1976) for housing flange dimensions. Consult SAE J618d (May, 1974) and J619d (May, 1974) for spring loaded clutch flywheel dimensions E and G and other dimensional data. Table 1 provides housing minimum internal dimensions for single and two flange spring loaded clutches.
