Grain entering a truck, trailer or grain cart at over 3 bushels per second can trap an adult in seconds. However, use a water extinguisher only on crop debris. Do not wear loose clothing that can become entangled with the machine.
Correct leaks immediately and clean the machine thoroughly after leaks or spills. Have you, or did someone you know purchase a new combine in the last few years and continued to use it in much the same way as the combine it replaced? Many times operators do not fully realize and take advantage of modern features. It is a proactive way to be sure your combine will operate at its best possible performance when you need it.
Customized Maintenance Inspections include a visual and functional inspection of your combine. They can be used as a pre-season or as a post-season tune-up. The combined advantages of Customer Maintenance Inspection services should result in a lower cost of ownership and higher resale values. Documented Service Promotes High Resale Value When you schedule your equipment for annual maintenance inspection services, your Case IH dealership places an annual UPTIME Action Maintenance decal on your equipment after each inspection, distinguishing your commitment to keep your machines running in top condition.
Because Case IH technicians use Customized Maintenance Inspection checklists for each inspection, you can rest assured the service is thorough and nothing is overlooked.
Daily maintenance items to check at the end of the day while the machine is at operating temperature. Additional checks are recommended and should be performed prior to starting-when the engine is cooled to ambient temperature. To avoid damage, do not strike the inside of the element with the air wand. Case IH No. Check the sight gauge periodically for a red pin that may become visible.
Figure 7. Do not wear gloves. Gloves can become soaked with hot coolant and burn the skin before the they can be removed. Do not use automotive grade coolant available from common retail outlets. It is not low silicate, and is inadequate for heavy-duty use. A test kit is available to evaluate coolant corrosion protection.
Fuel System The most reliable way to prevent fuel-related performance issues is to purchase only high quality, low sulfur fuel from a reputable supplier. The use of Bio-diesel fuel is on the rise.
Hydraulic System The hydraulic system works hard propelling, lifting, turning and controlling functions on your combine. Add oil should the level decrease to the bottom of the sight glass. System capacity is 15 US Gallons 57 liters. If the oil is not warm, operate the engine at least 10 minutes to warm the oil, then with the separator and feeder engaged for 5 minutes.
Make sure chain is properly aligned, especially after performing repairs. Pull the dipstick out, wipe clean and full re-insert. Then remove and check oil level on the dipstick. The same basic standards apply to belts, as chains. Roller Chain Drive chains work hard on a combine, and proper maintenance is crucial for reliable operation. Bearings Be sure to keep weeds and crop residue from wrapping on shafts near bearings. Over-greasing will also damage seals, shorting bearing life.
See table Although level checks may not have a scheduled frequency, operators should know the location of the gearboxes, and check for possible leakage during normal machine cleaning and inspection.

Check brakes more frequently if used often in hilly conditions or when using the brakes for turning. Wheel bolt torque must be checked when new and periodically thereafter. Solid-state components have little tolerance for errant voltage.
This includes positive AND negative cables. The electrical system uses two volt batteries connected in parallel. This means both positive cables connect to the electrical system, and both negative cables connect to ground. Keep the area clean for best air quality conditions. Cab environment and lighting controls are located in the overhead cab console. The right side of the display is used for vehicle and precision farming applications. A wide selection of information can be displayed in the Pro Display Area.
Draper speed should be set for a consistent windrow formation entering the combine. Fine-tuning as harvest progresses will allow you and your combine to maximize performance. In addition to providing threshing action, they also provide positive crop movement through the rotor cage. The aggressive nature of the spiked bar tears the crop mat apart, allowing grain to effectively separate from the straw.
The angle of cage transport vanes can be adjusted to control the rearward movement of crop material. Special settings will tend to reduce threshing and separating performance, so a balance of straw value and grain loss must be determined when making adjustments. Some simple steps should be taken as the combine is adjusted to match each crop and season. The pump will remain in this position until there is a demand for oil.
In low-pressure standby mode the pump produces less heat and uses less horsepower than an open-center system. Low pressure standby also makes starting the engine easier. Minimum system pressure is There is a 0. The dynamic sensor orifice connects the pump outlet port to the signal port of the pump compensator through the orifice check valve.
If the oil in the signal line can flow through the steering hand pump too freely a 0. This signal pressure of 3. The spring pressure of The flow of oil from the pump is controlled by the difference in pressure at opposite ends of the flow compensator spool. When a valve is opened to operate a function on the combine, the outlet pressure of the pump will drop. This drop in pressure is detected on the non-spring end of the flow compensator spool. The spring will now shift the spool and allow oil to drain from the pump control piston into the pump case.
The swash plate control spring will tilt the swash plate, causing the pump to. When the flow demand of the system is met, the swash plate will be tilted to provide only the flow required by the component s in use. The working pressure in the system is fed back to the spring-end of the flow compensator spool through the signal line.
The pump must produce flow at a pressure equal to the working pressure desired, plus enough to overcome the When the outlet pressure is high enough to overcome both the spring and work pressure, the flow compensator spool will shift allowing oil to flow to the control piston, causing the pump to destroke to match the demand. Should the hydraulic system stall-out under a high load, or a cylinder reach the end of its stroke, the pump will go into high-pressure standby until the load is overcome or the valve is returned to neutral.
When the system stalls-out, there will be no flow across the controlling valve. The pressure will then equalize on both ends of the flow compensator spool. The spring will then cause the flow compensator spool to shift. At the same time, the pressure will start to rise in the system until it is able to move the spring-loaded high-pressure spool.
This spring is set at When the high-pres- sure compensator spool shifts, it directs oil to the swash plate control piston, de-stroking the pump.
The pump will remain in the high-pressure standby mode until the load is overcome or the valve is returned to neutral. When the valve is returned to neutral, pressure is no longer available to the signal line.
The flow compensator spool will shift allowing oil to extend the control piston and destroke the pump. Signal line pressure is bled-off through a 0.
When the signal pressure is bled-off, the flow compensator spool will return the system to low pressure standby. This is due to the location of the signal line. The steering, reel drive, terrain tracker and header raise rates are variable by the operator, unlike the other functions, which are not adjustable.
For example, the steering speed can be affected by how fast the operator turns the steering wheel. The header raise rate can be increased or decreased by changing the raise rate setting on the Universal Display Plus monitor.
The signal line for the variable control systems steering, terrain tracker, reel drive and header raise is located after each control valve, monitoring the circuit work pressure. In this location, the signal line will sense actual working pressure in the cylinder s. When any of these functions are activated the jammer valve is also activated.
The jammer valve is used to direct full pump pressure into the signal line, this causes the PFC pump to go the high pressure standby. A supply side orifice in each valve controls the speed at which these function operated. The jammer valve is connected before the orifices that control the actuation speed.
As a result, the signal pressure sensed is not the actual working pressure at the cylinder s , but full system pressure. In this case, no pressure drop is detected and the oil pressure on either side of the flow compensator spool will remain equal.
Within the PFC system there are five checks valves located in the signal lines. One at the header valve, one at the steering priority valve, one in the reel drive valve and two in the lateral tilt valve. The purpose of these checks is to allow the highest signal line pressure to get back to the compensator.
This will make sure that the component with the highest-- pressure demand is satisfied. Supply to Steering Hand pump. Steering Signal Check Valve. The steering priority valve is integral with the main stack valve on the left side of the combine.
The primary function of the steering priority valve is to maintain a priority flow of oil to the steering system. Oil from the PFC pump is directed to the inlet of the steering priority valve. Inside the valve is the priority spool, which is spring biased. The spring will position the spool so incoming oil will to go to the steering hand pump first. When steering is not being used, pressure will increase due to the closed-center steering hand pump. This build-up of pressure is directed to the non-spring end 12 of the priority spool through a screened 0.
At the same time, a screened 0. The dynamic sensor orifice keeps the signal line filled with oil to keep the steering responsive. At the same time this oil is allowed to drain to the reservoir through the orifice in the steering hand pump spool. If the oil in the signal line can flow through the steering hand pump too freely, the 0.
This pressure in the signal line plus the With the oil on the spring-side The priority spool will meter just enough oil to the steering circuit to make-up for the oil being bled-off through the 0. On the spring-end of the steering priority spool is an orifice 8 fitting that connects the steering hand pump signal line to the steering priority valve. This orifice fitting has a 0.
The steering hand pump circuit is opened when steering is required. This will cause a pressure drop on the non-spring end of the priority spool. The spring will shift the priority spool to direct oil out to the steering hand pump.
The PFC pump will stroke to meet the steering demand. When steering demand is satisfied, pressure will start to build on the non-spring end of the priority spool.
The pressure will overcome the spring, shifting the priority spool, thus allowing excess oil to be supplied to the main valve assembly if required. Threaded into the steering priority valve is a screened 0. This orifice check allows oil pressure to get to the compensator when in low-pressure standby mode and when steering the combine. It also allows signal line pressure, once a function has been completed, to bleed from the compensator to reservoir through the steering hand pump, which de-strokes the pump.
This hand pump is a closed-center, load-sensing design to minimize horsepower consumption and heat generation. The NA unit is cc with 4. Two 2. When there is no demand for steering, the spring-centered main spool and sleeve block the oil inlet port and the ports to the steering cylinder.
At the same time the main spool and sleeve open a passage so the signal line can drain to the reservoir. The 0. At the same time this oil is allowed to drain to the reservoir through the orifice 1 in the steering hand pump. The orifice in the steering hand pump will create a back pressure of The internal check valve between the supply and return passages is closed at this time.
Oil from the PFC pump enters the steering hand pump at the supply port. This opens the spring-loaded check valve and seats the recirculation check. As the steering wheel is rotated left or right , the main spool will move within the sleeve. This movement will direct oil to the metering section as well as to the signal line.
The metering section begins to rotate with the rotation of the steering wheel. This moves oil from the PFC pump to the rod-end or the base end of the cylinder depending on the direction of rotation. At this point the oil pressure going to the cylinders is also transmitted back to the compensator by way of the signal line. Oil returning from the cylinder is directed back to the main spool and sleeve, then out the return port of the steering hand pump to the oil filter.
When rotation of the steering wheel is stopped, the spring-centered main spool and sleeve return to the neutral position. This stops oil flow to the metering section and traps oil in the cylinder. Welcome to ManualMachine. We have sent a verification link to to complete your registration.
