The present disclosure provides a captive sprocket system for an engine, comprising: a sprocket including a first sprocket gear, a second sprocket gear and a retaining disc having a diameter and a thickness; a cylinder block having a bore with a central opening and a plurality of threaded bosses, the plurality of threaded bosses together forming an axial support surface and a radial location surface, the axial support surface and the radial location surface being sized to receive the retaining disc of the sprocket to support and locate the sprocket; and a plurality of captivation screws configured to be received by the plurality of threaded bosses, each captivation screw having a head with a lower surface which, when the captivation screw is received by a threaded boss, overlies the retaining disc and retains the sprocket in the bore.

System and method for a captive sprocket in an engine

An improved belt tensioning system for an agricultural round baler that increases belt tension to reduce slippage between the belts and the driving rolls during the initial stage of a bale forming cycle when the bale chamber is empty and as the belts are beginning to be rolled. The system includes an accumulator that is pressurized by the tensioning system as a bale is being formed. The accumulator pressure may then be directed to a hydraulic cylinder included in a bale density system to increase tension in the belts after a completed bale is ejected and the bale chamber is being reset for the next bale.

Accumulator system for round baler belt pre-tension

An improved belt tensioning system for an agricultural round baler that temporarily bypasses a bale density, belt tension increasing system while the baler tailgate is moved out of a closed position thereby allowing the tailgate to be opened without encountering resistance form the belts and the belt tensioning system. Bypass operation is coordinated with the tailgate position so that the bypass is not activated when such activation would frustrate operation of the belt tensioning system. In balers equipped with a belt tensioning pre-tensioning system, the bypass operation is further coordinated with the pre-tensioning system to maintain proper pre-tension function.
