Heavy Truck and Bus Retarder Downhill Performance Mapping Procedure
2000-05-01
CURRENT
J1489_200005
The procedure covers the estimation of the total retardation capability available to a specific vehicle from: a Natural retardation (rolling resistance, aerodynamic drag, etc). b Engine drag c Engine, integral automatic transmission, driveline or trailer-axle retarders It assumes that foundation brakes are not used for maintaining speed on long mountain descents. Retardation is rated in terms of the maximum grades on which stable control speeds can be maintained for each gear over the range of highway speeds appropriate to that gear. For each gear, the calculation procedure determines maximum grades for at least four values of control speed ranging from the vehicle velocity corresponding to full load governed engine rpm, to the vehicle velocity corresponding to the engine rpm at minimum (idle) speed. In addition, the calculation procedure provides information on the total retarding power available for each gear.

Torque Ratings for Power Take-off Mounting Pads
2017-09-19
CURRENT
J2662_201709
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.

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.)

SAE Nodal Mount
2017-08-14
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.

Clutch Requirements for High-Torque Truck and Bus Engines
2018-01-18
CURRENT
J2408_201801
Although not limited to, these clutch requirements are normally used on trucks considered as Heavy Duty (Class 8). This SAE Information Report defines and discusses clutch and related component configurations which will become the subject of future SAE Recommended Practices to promote standardization of clutch installations and mounting dimensions for use with pull-type heavy-duty clutches.
