In-line, Elbow, and Tee Flanged Connectors for use with SAE J518-1/ISO6162-1 Components

2015-02-03
WIP
J518/4
This document standardizes the design of connector blocks used for joining SAE J518-1/ISO 6162-1 (Code 61) flange heads with other SAE J518-1/ISO 6162-1 (Code 61) flange heads with straight, elbow, and tee geometries. The blocks specified in this document are designed to provide for very compact installations. As a result, the tap depths specified in this document do not conform to those specified in SAE J518-1/ISO 6162-1 to allow for a minimal bend radius in the elbow and tee configurations. This document specifies both inch and metric configurations

Round Head Bolts

1990-01-01
CURRENT
J481_199001
Round head bolts are made in two body styles: (a) A full size body, with a maximum diameter somewhat greater than the nominal diameter (not an SAE Standard except for ribbed neck bolts, Table 3); and (b) an undersize body, with a minimum diameter approximating the pitch diameter of the thread and a maximum diameter never exceeding nominal (SAE standard for all types except ribbed neck bolts). The body diameter of either style may be exceeded by a reasonable swelling or fin under the head, or under corners of the square necks, to the extent that serviceability is not affected.

Alignment of Nut Slots

1990-01-01
CURRENT
J484_199001
This method of gaging alignment of nut slots allows equal variations for location of the cotter pin hole in the bolt and location of slots in the nut. To inspect the nut, the slotted gage is inserted through the nut hole from the bearing surface of the nut. Alignment of slots is considered satisfactory if the gage pin can be slipped into the gage and nut slots without interference.

Air Conditioning Service Procedures for Heavy duty and Off-Highway work Machines using R-134a refrigerant

2016-09-12
WIP
J3126
This recommended practice provides technicians with safe and efficient techniques and general equipment recommendations for servicing Mobile Air Conditioning (MAC) systems in heavy duty and off-highway work machines. Presently, R-134a is the only approved refrigerant for use in mobile heavy duty and off-highway equipment and therefore this document primarily covers the servicing of R-134a systems. Since the technician may encounter other refrigerants a brief explanation on the identification safe handling of each refrigerant will be introduced.

Coiled Tubing Assemblies for Heavy Duty Air Brake Applications

2013-04-30
WIP
J3041
This SAE Standard establishes the minimum performance and endurance requirements for coiled air brake tubing assemblies used for hookup between tractors, trailers and converter dollies. The Standards SAE J844 and SAE J246 along with J1131 must be consulted to determine the complete performance and endurance requirements of individual components of the system. Related TMC Recommended Practices may be consulted for information associated with selection, installation and inspection of these assemblies. This document is intended to set out requirements for the majority of conditions rather than for specialized applications or environments.

J2321/4
This specification sheet establishes requirements for a low collapse pressure configuration filter element of a specific configuration with a minimum filtration ratio of 75 for particles larger than ? μm when designed and tested in accordance with SAE J2321 and this specification sheet. Note: The efficiency and dirt capacity have not yet been determined..

Performance Requirements for Nonmetallic Air Brake System Tubing

2014-08-26
WIP
J2547
This SAE Standard covers the minimum requirements for nonmetallic tubing as manufactured for use in air brake systems which tubing is different from that described in SAE J844. It is not intended to cover tubing for any portion of the system which operates continuously below - 40 degrees C or above +93 degrees C, above a maximum working gage pressure of 1.0 MPa, or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections, which maintain a basically fixed relationship between components during vehicle operation. Coiled tube assemblies required for those installations where flexing occurs are covered by this document, SAE J1131 and SAE J2494-3, to the extent of setting minimum requirements on the essentially straight tube and tube fitting connections which are used in the construction of such assemblies.

Off-Road Self-Propelled Work Machines Operator enclosure environment Part 4:Heating, ventilating and air conditioning (HVAC) test method and performance

2014-09-16
WIP
J3078/4
J3078/4 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. J3708/6 is to be used in conjunction with J3078/4 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine’s operator enclosure heating, ventilating and air conditioning systems are established in J3708/4.
