(7) Guide The manual barring group provides a means of slowly turning the flywheel in order to perform service work on the engine.Note: Prelube the engine as you rotate the crankshaft during the normal maintenance operations. Refer to the Testing And Adjusting Section of this manual.A 3/4 inch hex drive on the end of shaft (2) is used to turn gear (1). Guide (7) must be loosened before the shaft is engaged or the shaft is turned.Shaft (2) is spring loaded. The shaft must be pushed toward the flywheel in order to engage gear (1) in the flywheel ring gear.The shaft can be engaged in position against the flywheel by pushing in on knob (3). Stem (4) engages in slot (5) of shaft (2). When the knob is pushed inward, the O-ring seals shut off the pressure air source (signal to the relay valve) to the starting motor. The loss of air pressure will prevent the start-up of the engine.The barring group can be used to prevent the rotation of the crankshaft. The inside of spacer (6) is splined. Shaft (2) and the flywheel will be locked in position when the manual barring group is engaged and guide (7) is tightened according to the torque that is listed in the engine's Specifications manual.When the manual barring group is not active, this component must be disengaged from the flywheel.
