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.

Although not limited to, these clutches are normally used on trucks considered as Medium-Duty (Class 6 and 7), as well as Heavy-Duty (Class 8).

This SAE Recommended Practice applies to all forms of diesel and natural gas engines fueled by the combination of diesel fuel and natural gas.

This SAE Recommended Practice describes STANDARD-DUTY and EXTREME-DUTY Pilot Bearing requirements and sizes for class 6, 7, and 8 on-highway trucks and buses that use diesel engines and manual transmissions. The recommendations may apply to a wide range of other pilot-bearing applications, such as agricultural, industrial, and construction equipment.

This SAE Recommended Practice provides guidance for the construction, operation, and maintenance of CNG powered medium and heavy-duty trucks. The intent of this document is to cover TRUCKS (6350 kg (14 001 gvw pounds) and above) and specifically excludes passenger vehicles such as: buses, recreational vehicles, motor homes and/or passenger vehicles which may incorporate a truck chassis in their construction.

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.

This SAE Recommended Practice establishes a single bolt pattern for both No. 1 and No. 2 clutch housings (see Fig. 1). This four-bolt pattern is designated to give commonality of mounting brackets in existing frame rails. The 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 a 15.5 in two-plate clutch. The bolt pattern due to its symmetry allows reversing or inverting of brackets to attain change in vertical or horizontal positioning with fewer brackets. The phi (ϕ) symbol is for the convenience of the user in locating areas where technical revisions have been made to the previous issue of the report. If the symbol is next to the report title, it indicates a complete revision of the report.
