APPLICATION GUIDE TO RADIAL LIP SEALS
1989-08-01
HISTORICAL
J946_198908
This 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 recommended practice is to make standard information available in one document to the users of oil seals.

Chemical Methods for the Measurement of Nonregulated Diesel Emissions
2002-10-21
CURRENT
J1936_200210
This SAE Recommended Practice encompasses analytical procedures for measuring nonregulated diesel exhaust emissions. Methods are recommended for the measurement of aldehydes and carbonyl compounds, sulfates and the characterization of diesel exhaust particulates. Informational methods are presented for the measurement of polycyclic aromatic hydrocarbons (PAH) in diesel exhaust particulate samples. The procedures are based on current proven chemical and engineering practices. However, it should be noted that the procedures are subject to change to keep pace with established experience and technology. The procedures are intended for use in the collection, analysis, and characterization of emissions from diesel engines. They are to be used as a guide in standardizing practices so that the results from various sources can be compared with some degree of accuracy. The specific purpose of each chemical method is presented at the beginning of each method section.

Determination of Sulfur Compounds in Automotive Exhaust
2002-10-21
CURRENT
J1280_200210
This SAE Information Report deals exclusively with the determination of sulfur compounds in automotive exhaust. Engine operating cycles and interpretation of results are not covered. Methods described in detail are those that have been or are being used by various laboratories. None are specifically recommended as superior to others. Since intensive measurement of automotive sulfur compounds is a relatively new activity, methods and practices have changed rapidly. Some methods are more experimental than others and are so noted in the test.

ENGINE WEIGHT AND DIMENSIONS
1990-04-01
HISTORICAL
J2038_199004
This SAE Recommended Practice has been developed to provide a uniform method for reporting the weight and dimensions of internal combustion engines. SAE J2038 is not intended to cover the technical interface between the engine and transmission. To locate the rear of the engine crankshaft in relationship to the rear of the flywheel housing, refer to SAE J617.

HOUSING INTERNAL DIMENSIONS FOR SINGLE AND TWO PLATE SPRING LOADED CLUTCHES
1987-08-01
HISTORICAL
J373_198708
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.

Manual Transmission and Transaxle Efficiency and Parasitic Loss Measurement
2011-09-02
CURRENT
J2453_201109
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.

Manual Transmissions and Transaxle High-speed Lubrication, Unbalance, and Seizure Evaluation
1999-09-09
HISTORICAL
J2132_199909
It is anticipated that this SAE Recommended Practice will be only one step in a comprehensive evaluation of the vehicle/transmission application. This document alone is not adequate “due care” to insure against high-speed seizure or other high-speed problems. The notes printed in bold print throughout the practice convey important information about the test itself or the results and should be considered carefully. All references to transmissions also apply to transaxles, except for the unbalance evaluation which applies only to rear-wheel-drive transmissions with propeller shaft output.
