This SAE Recommended Practice establishes a single bolt pattern for the No. 1 clutch housing (see Figure 1) and the No. 2 clutch housing (see Figure 2). These four bolt patterns are designated to give commonality of mounting brackets in existing frame rails. The 420 mm (16.5 in) span, pad face to pad face, allows the ease of installation in existing frame rail widths. This is also the minimum spacing which will accommodate commonly used clutches.
The code provides test procedures and methods of calculating a brake rating from the data obtained for brakes used in highway commercial vehicles over 4.5 T (10 000 lbs) GVWR air and hydraulic. Some general correlation may be expected between brake ratings established by this means and those obtained from vehicle tests such as outlined in SAE J880. The brake rating power, kW (hp) calculated by conduct of this code is an arbitrary index of performance of the brake and drum when tested by this procedure and may be appreciably different from the values obtained by other techniques.
This SAE Recommended Practice provides test procedures, requirements, and guidelines for high-mounted stop lamps intended for use on vehicles 2032 mm or more in overall width. This document applies to trucks, motor coaches, van type trailers, and other vehicles with permanent structure greater than 2.8 m high. This document does not apply to school buses, truck tractors, pole trailers, flat-bed trailers, and trailer converter dollies. The purpose of the high-mounted stop lamp or lamps is to provide a signal over intervening vehicles to the driver of following vehicles.
This SAE Standard provides test procedures, requirements, and guidelines for stop lamps and turn signal lamps intended for use on vehicles 2032 mm or more in overall width. Stop lamps and front- and rear-turn signal lamps conforming to the requirements of this document may be used on vehicles less than 2032 mm in overall width.
This SAE Standard covers complete general and dimensional specifications for tube fittings of the spherical and flanged sleeve compression types for use in the piping of air brake systems on automotive vehicles. The spherical sleeve compression type Figures 1A to 5 and Tables 1 to 3 is intended for use with annealed copper alloy tubing per SAE J1149, Type 1. The flanged sleeve compression type Figures 6A to 11 and Tables 4 to 6 is intended for use with nylon tubing per SAE J844. It is not intended to restrict or preclude other designs of a tube fitting for use with SAE J844, air brake tubing. Performance requirements for SAE J844 are covered in SAE J1131. See SAE J1131 for the Performance Requirements of Reusable (Push to Connect) Fittings Intended for Use in Automotive Air Brake Systems.
This SAE Standard establishes the specifications and content for labeling of ROPS, FOPS, and OPS, which may commonly be a part of construction, forestry, mining, and industrial machines. The label content herein shall be applied to a ROPS and/or FOPS and/or OPS on any of these machines.
This standard applies to buckets of loaders (as defined by SAE J1057a, Identification Terminology of Earthmoving Machines). This method applies primarily to buckets having parallel sides and a cutting edge parallel to the top edge of the top edge of the back sheet. Moderately clipped back sheet corners will introduce no appreciable errors. Bucket teeth, tooth adapters, as well as other similar local discontinuities are ignored. a. Interpretation of irregular shaped cutting edges is identified in 4.4. b. Interpretation of irregular shaped side sheets is identified in 4.5.
This SAE Recommended Practice establishes the test procedure, environment, and instrumentation for determining the sound levels of motorcycles under full throttle acceleration and closed throttle deceleration.
This dictionary of terms was prepared for use by those with a need to describe and understand the dynamics and handling of two-wheeled, single track vehicles. It is intended to span the gap between vehicle dynamics specialists and those with a more general interest. This report is pertinent to such areas as vehicle design and development, the description of two-wheeler properties, rider training and education, and the preparation of standards and regulations. This report was prepared by the SAE Motorcycle Committee, which solicits suggestions for improvements and additions to be considered in future revisions. Comments should be directed to SAE Headquarters.
This SAE Recommended Practice is applicable to two- or three-wheel motorcycles intended for highway use. Unless noted, requirements apply to both metallic and nonmetallic tanks. Accessory or aftermarket tanks as well as original equipment tanks are covered.
Fulfillment of the intended purpose requires testing as follows: A laboratory test, under repeatable and controlled loading, to permit analysis of the ROPS for compliance with the performance requirements of this SAE Standard. Either the static test (6.1) or the dynamic test (6.2) shall be conducted. A crush test to verify the effectiveness of the deformed ROPS in supporting the tractor in an upset attitude. A field upset test under reasonably controlled conditions, both to the rear and side, to verify the effectiveness of the protective system under actual dynamic conditions. (See 188.8.131.52 for requirements for the omission of this test). In addition to the laboratory and field loading requirements, there is a temperature-material requirement. (See 7.1.2.) The test procedures and performance requirements outlined in this document are based on currently available engineering data.
The purpose of this SAE Recommended Practice is to provide a selection of disc wheels for industrial and agricultural application with a maximum of interchangeability. This is accomplished by establishing five groups of disc wheels, in each of which the hub mounting elements are common. These groups are designated 4 bolt, 5 in bolt circle; 5 bolt, 4.5 in bolt circle; 5 bolt, 5.5 in bolt circle; 6 bolt, 6 in bolt circle; and 8 bolt, 8 in bolt circle. Further, this document establishes an SAE part number and the maximum rated radial load for each standard wheel. In addition, the document requires the wheel manufacturer's name or trademark to be impression stamped on the wheel with location at the discretion of the manufacturer.
This SAE Recommended Practice establishes the mounting hardware to be used with demountable rims, wheels for demountable rims, rim spacers designed for 28 degrees bevel mounting systems, and intended for use on commercial vehicles. The dimensions given are those necessary to maintain serviceability and interchangeability of mounting hardware. This document is divided into two sections. Section 1 establishes the practice for new designs for mounting hardware. Section 2 records information on current mounting hardware. Special and less common applications are not covered in this document.
This SAE Standard specifies procedures for measuring operator and exterior sound levels emitted by self-powered trenching machines regardless of engine size. This procedure does not cover operation of devices such as backup alarms, horns, or accessories such as paving breakers. The sound levels obtained using this procedure are repeatable and representative of the higher range of sound levels generated by machines under actual field operating conditions, but do not necessarily represent the average sound level over a field use cycle. Measurement and calculation of the operator's sound exposure should follow SAE J1166.
