32.3.1.1. Bushing Bearing

A Bushing bearing is defined between two bodies. The created position types are five:

  • Engine Block & Shaft Main (EB_SM)

  • Shaft Pin & Connecting Rod (SP_CR)

  • Connecting Rod & Piston Pin (CR_PP)

  • Piston Pin & PisTon (PP_PT)

  • Engine Block & Balancing Shaft (EB_BS)
