Flywheels for Single-Plate Spring-Loaded Clutches

2012-05-31

CURRENT

J618_201205

This SAE Recommended Practice applies to flywheels for dry spring-loaded clutches used on internal combustion engines. Figure 1 and Tables 1, 2, and 3 report information currently used in the industry. Clutches requiring other dimensions are also manufactured. Dimensions given are primarily for single-plate clutches. Flywheels for two plate clutches have the same dimensions if an adaptor for the intermediate plate and second driven disc is supplied with the clutch. If instead the flywheel is to be extended to adapt the intermediate plate and second driven member, consult the clutch manufacturer for the required J dimension and drive arrangements for the intermediate plate. See SAE J1806 for flywheels for size 14 and 15.5 two plate pull-type clutches.

CURRENT

J1094_201109

This SAE Information Report describes uniform laboratory techniques for employing the constant volume sampler (CVS) system in measuring various constituents in the exhaust gas of gasoline engines installed on passenger cars and light trucks. The techniques described relate particularly to CVS systems employing positive displacement pumps. This is essentially an almost obsolete system relative to usage in industry and government. Current practice favors the use of a critical flow venturi to measure the diluted exhaust flow. In some areas of CVS practice, alternative procedures are given as a guide toward development of uniform laboratory techniques. The report includes the following sections: Introduction 1. Scope 2. References 2.1 Applicable Publications 3. Definitions 4. Test Equipment 4.1 Sampler 4.2 Bag Analysis 4.3 Modal Analysis 4.4 Instrument Operating Procedures 4.5 Supplementary Discussions 4.6 Tailpipe Connections 4.7 Chassis Dynamometer 5.

Sleeve Type Half Bearings

2011-06-10

CURRENT

J506_201106

This SAE Standard defines the normal dimensions, dimensioning practice, tolerances, specialized measurement techniques, and glossary of terms for bearing inserts commonly used in reciprocating machinery. The standard sizes cover a range which permits a designer to employ, in proper proportion, the durability and lubrication requirements of each application, while utilizing the forming and machining practices common in manufacture of sleeve type half bearings. Not included are considerations of hydrodynamic lubrication analysis or mechanical stress factors of associated machine structural parts which determine the nominal sizes to be used, selection of bearing material as related to load carrying capacity, and economics of manufacture. For information concerning materials, see SAE J459 and SAE J460. These suggested sizes provide guidelines which may result in minimal costs of tooling but do not necessarily represent items which can be ordered from stock.

This SAE Information Report covers thin coatings of resinous based materials that can be placed on the metallic outer diameter of radial lip-type shaft seals to provide sealing when the mating bore finish is too rough to insure a proper seal (typically when finish exceeds 2.54 µm Ra, or in pressurized applications.) The coatings will have the following characteristics: a. Material shall dry to a tough, flexible, and non-tacky film. b. Thickness typically ranges from 0.005 to 0.076 mm. c. It shall not crack, flake, or powder when scraped. d. Coating shall adhere to seal case as noted in text. e.
