Nomenclature and Terminology for Truck and Bus Drive Axles

1991-04-01
HISTORICAL
J923_199104
This SAE Recommended Practice outlines basic nomenclature in common use for truck and bus drive axle designs. Over a period of years there have been many different designs introduced; however, for this report, only the most common have been selected and only their general construction is illustrated to show the nomenclature of the various parts.

Openings for Six- and Eight-Bolt Truck Transmission Mounted Power Take-Offs

2017-11-03
CURRENT
J704_201711
The accompanying mounting and gear locations are applicable for all general installations of power take-off on the transmission gear box of motor trucks and tractors where the size of the transmission permits. The heavy-duty type opening can be adapted to the regular-duty type by the use of an adapter with 6.35 mm (0.25 in) flange thickness with appropriate bolt pattern and thread engagement. (See Figures 1 and 2.)

Rating of Winches

2017-11-03
CURRENT
J706_201711
This SAE Standard applies only to new winches which are primarily designed for intermittent pulls and lifts and whose configuration and condition are the same as when they were shipped by the manufacturer. They are not intended to be used in any manner for the movement of personnel. They may be driven by any power source recommended by the manufacturer and will be capable of being powered in either direction. They will be equipped with an automatic safety brake system to control a load when lowering under power and positively hold a load when power is not being delivered to the winch. A hydraulic flow control valve or similar device may be used in the brake system to control a load when lowering under power. A clutch to release the drum for “free-spooling” may be provided and will be designed not to disengage itself under load. A drag brake may be provided to control “free-spooling,” but will not be relied on to control or hold a load.

SAE Nodal Mount

CURRENT
J1134_201708
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.

Snap-Acceleration Smoke Test Procedure for Heavy-Duty Diesel Powered Vehicles

2018-02-15
CURRENT
J1667_201802
This SAE Recommended Practice applies to vehicle exhaust smoke measurements made using the Snap-Acceleration test procedure. Because this is a non-moving vehicle test, this test can be conducted along the roadside, in a truck depot, a vehicle repair facility, or other test facilities. The test is intended to be used on heavy-duty trucks and buses powered by diesel engines. It is designed to be used in conjunction with smokemeters using the light extinction principle of smoke measurement. This procedure describes how the snap-acceleration test is to be performed. It also gives specifications for the smokemeter and other test instrumentation and describes the algorithm for the measurement and quantification of the exhaust smoke produced during the test. Included are discussions of factors which influence snap-acceleration test results and methods to correct for these conditions.

J2662_200307
This SAE Recommended Practice is intended to serve as a reference for the amount of torque that a Power Take-Off can induce on the transmission mounting pad. This document will apply to six-bolt, eight-bolt, and rear mounted power take-offs.
