Main Drive Belt Adjustment - Haybuster H-1130 Operating Instructions And Parts Reference

2.15 Main drive belt adjustment

Power is transferred from the drive shaft to the rotor through drive belts and two sheaves. Maintaining the proper
tension on these belts is critical for reaching optimum grinder performance. A spring tensioning system is used on the
H-1130 grinder to maintain tension as belts stretch over time. To properly tension the drive belts turn the tensioning rod
until the spring caps come into contact with the tubes that the springs are seated into. DO NOT OVERTIGHTEN!
The two sheaves must be running parallel, if they are not the belts will not track, premature belt wear or belts running
off of the sheaves will result. Adjust sheave alignment if needed.
Discharge Conveyor Flow Control Valve
A flow control valve is located on the side of the discharge conveyor. This valve allows the operator to control the
speed of the discharge conveyor; it will not vary the speed of the belly augers.
Adjusting the discharge conveyor flow control valve
The discharge conveyor flow control valve can be used to slow the discharge conveyor down which is helpful when
grinding in windy conditions, when loading trucks, or when the grinder output is low. The flow to the hydraulic motor
can be varied from approximately zero to the maximum flow by adjusting the valve from min (0) to max setting (10).
Note: Whenever this valve is used to decrease the speed of the discharge conveyor, heat will be
generated. The hydraulic system may not be able to dissipate the excess heat generated in warm
operating conditions. Always be aware of the hydraulic oil temperature; a thermometer is located on
the side of the hydraulic reservoir. If the oil temperature becomes greater than 175°F (79°C) adjust
the valve to max setting (10).
