Engine Flywheel Housing and Mating Transmission Housing Flanges

SAE IC Powertrain Steering Committee
  • Ground Vehicle Standard
  • J617_201404
  • Current
Published 2014-04-16 by SAE International in United States
This SAE Standard specifies the major dimensions and tolerances for Engine Flywheel Housings and the Mating Transmission Housing Flanges. It also locates the crankshaft flange face or the transmission pilot bore (or pilot bearing bore) stop face in relation to housing SAE flange face. This document is not intended to cover the design of the flywheel housing face mating with the engine crankcase rear face or the design of housing walls and ribs. Housing strength analysis and the selection of housing materials are also excluded. This document applies to any internal combustion engine which can utilize SAE No. 6 through SAE No. 00 size flywheel housing for mounting a transmission.

Spark Arrester Test Procedure for Large Size Engines

SAE IC Powertrain Steering Committee
  • Ground Vehicle Standard
  • J342_201303
  • Current
Published 2013-03-26 by SAE International in United States
This SAE Recommended Practice establishes equipment and procedures for the evaluation of the effectiveness and other performance characteristics of spark arresters or turbochargers used on the exhaust system of large engines normally used in a railroad locomotive, stationary power plant, and other similar applications. This document does not cover applications requiring flame arresting, exhaust gas cooling, or isolation from explosive gases. Two test methods are presented: a laboratory test using ambient air (cold test) and an engine test using exhaust gases (hot test). The hot test is preferred. Arresters tested by the provisions of this document can be expected to perform as tested when tilted no more than 45 degrees from their normal position. Test results from a spark arrester or turbocharger evaluated by the hot test can be applied to different engines of similar design, provided the data shows it to be effective in the applicable flow ranges. Certain design and performance characteristics, which represent current requirements by regulatory agencies for qualification and approval under this document, are listed in Appendix A.

Industrial Power Take-Offs With Driving Ring-Type Overcenter Clutches

SAE IC Powertrain Steering Committee
  • Ground Vehicle Standard
  • J621_201210
  • Current
Published 2012-10-23 by SAE International in United States
This SAE Standard defines installation dimensions of industrial power take-offs with driving ring-type overcenter clutches. Table 1 and Figure 1 give dimensions for power take-offs. For dimensions and tolerances of power take-off flanges and flywheels, see SAE J617 and J620, respectively.

Flywheels for Industrial Engines Used With Industrial Power Take-Offs Equipped With Driving-Ring Type Overcenter Clutches and Engine-Mounted Marine Gears and Single Bearing Engine-Mounted Power Generators

SAE IC Powertrain Steering Committee
  • Ground Vehicle Standard
  • J620_201210
  • Current
Published 2012-10-23 by SAE International in United States
This SAE Standard defines flywheel configurations for industry standardization, interchangeability, and compatibility. Table 1 and Figure 1 give the dimensions for the flywheels. For dimensions of industrial power take-offs with driving-ring type overcenter clutches, see SAE J621. For flywheel dimensions for engine-mounted torque converters without front disconnect clutch, see SAE J927.

Engine Flywheel Housings with Sealed Flanges

SAE IC Powertrain Steering Committee
  • Ground Vehicle Standard
  • J1172_201210
  • Current
Published 2012-10-23 by SAE International in United States
This SAE Recommended Practice defines flywheel housing flange configurations for applications requiring "O" ring sealing of the flange pilot bore. Table 1 and Figure 1 show dimensions that are different from those in SAE J617. All other dimensions and tolerances of SAE J617 apply.
