CHAPTER 12 STORAGE

After the harvesting season is over, store the Disc Conditioner in a dry place where it is not exposed to weather or livestock.

Before Storing

Perform the following preparations on the Disc Conditioner, before placing the unit into off-season storage:

1.Release tension from the Drive Belt.

2.Wash off the entire machine. Take special care to remove gum and accumulated dirt from the Cutterbar.

3.Remove trash and debris which may be wrapped around Shafts and/or lodged against Bearings.

4.Repaint any areas where the paint has been worn off or brush motor oil on the these areas.

5.Lubricate the entire machine following the information in the Lubrication chapter of this manual. MAKE SURE to change the Chain Drive, Gearbox and Cutterbar oil. Apply motor oil to adjusting bolt threads.

6.Apply grease to any exposed Cylinder Rods.

7.Take note of any damaged or missing parts or attaching hardware; order and replace them during the off-season.

8.Check all hydraulic components, hoses and fittings for damage or leaks; make repairs or corrections, as required.

9.If the unit is to be stored outside where rain or snow will contact the unit, MAKE SURE to clean out the drain slots in the Roll Pressure Spring Compartment. The Compartment is located under the top front Cover of the Header Assembly and the slots are in the bottom front corners of the Compartment.

After Storing

After taking the Disc Conditioner out of storage and before the start of the harvesting season, carefully check the unit over and make the following inspections and preparations:

1.Replace all Guards, Shields and Covers. Review and re-familiarize yourself with all safety precautions outlined in the Safety chapter of this manual.

2.Remove any trash or debris which may have accumulated on the unit during storage.

3.Check and re-inflate the Tires and re-torque the Wheel lugs.

4.Realign and re-tension the Drive Belt using the procedures outlined in the Service chapter.

5.Readjust the Flotation Springs tension.

6.Inspect Cutterbar Knives.

7.Lubricate the entire machine following the information in the Lubrication chapter of this manual.

8.Check Drive Chain tension following the information in the Service chapter of this manual.

9.Perform the Clutch run in procedure as outlined in the Steps below in accordance with the type of Driveline (540 RPM or 1000 RPM) your unit is equipped with.

540 R.P.M. Clutch Run In

Tools required: 1/4″ hex allen wrench, scale or vernier dial caliper.

1.MAKE SURE the tractor is shut off and the PTO is disengaged.

2.Disconnect the Driveline from the tractor.

3.Use the vernier to measure the lengths of the Springs through all three of the 3/8″ access holes. Include the thickness of the Plate in the measurements. Record these dimensions so that the Clutch can be reset to these same settings.

NOTE: Be as accurate as possible. An error as small as 1/64″ from the original dimension to the new dimension can cause a difference of up to 15% in torque.

4.Locate the six cap screws on the Clutch. Reduce the load on the screws evenly to avoid damage to the Clutch. Loosen the six screws 1/2 turns per screw at a time until all screws are just loose.

5.Attach the implement to the tractor and the driveline to the tractor PTO.

6.Start the tractor. Engage the PTO and run for a few minutes or until the Clutch visibly smokes, at which time, disengage the tractor PTO.

7.Disconnect the Driveline from the tractor.

8.Tighten the six cap screws 1/2 turn per screw at a time until the desired measurement recorded in Step 3. is reached in all three of the 3/8″ access holes.

NOTE: Be as accurate as possible! An error as small as 1/64″ from the original dimension to the new dimension can cause a difference of up to 15% in torque. Overtightening could cause the Clutch to fail to slip.

9.Grease the fitting on the Yoke which lubricates the Overrunning Clutch mechanism. Use Shell Super Duty or an equivalent lithium grease.

10.The Clutch is now ready for use.

1000 R.P.M. Clutch run in

Tools required: 9/16″ box wrench or socket, scale or vernier dial caliper.

1.MAKE SURE the tractor is shut off and the PTO is disengaged.

2.Disconnect the Driveline from the tractor.

3.Use the scale or vernier to measure the lengths of all of the Springs. Record these dimensions so that the Clutch can be reset to these same settings.

NOTE: Be as accurate as possible. An error as small as 1/64″ from the original dimension to the new dimension can cause a difference of up to 15% in torque.

4.Locate the six bolts on the Clutch. Reduce the load on the bolts evenly to avoid damage to the Clutch. Loosen the six nuts 1–2 turns per bolt at a time until all nuts are just loose, then tighten all nuts one turn.

5.Attach the implement to the tractor and the driveline to the tractor PTO.

6.Start the tractor. Engage the PTO and run for a few minutes or until the Clutch visibly smokes, at which time, disengage the tractor PTO.

7.Disconnect the Driveline from the tractor.

8.Tighten the six nuts 1/2 turn per nut at a time until the desired measurement recorded in Step 3 is reached.

NOTE: Be as accurate as possible! An error as small as 1/64″ from the original dimension to the new dimension can cause a difference of up to 15% in torque. Overtightening could cause the Clutch to fail to slip.

9.Grease the fitting on the Yoke which lubricates the Overrunning Clutch mechanism. Use Shell Super Duty or an equivalent lithium grease.

10.The Clutch is now ready for use.

After the above steps have been performed, hook up the unit to the tractor and connect the Front Telescoping Drive. Then, follow the Break-in procedure as outlined in the Preparing For Field Operation chapter of this Manual. Then, exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8) and make the following inspections: a.Check for overheated Bearings b.Check for loose Bearing Collars or Flanges c.Check for excessively worn Bearings d.Check for loose Sprockets, Chains or attaching hardware e.Check for missing Keys

Chapter 13 Troubleshooting

NOTE: This Troubleshooting guide presents problems, causes and suggested remedies beyond the extent of loose, worn or missing parts and it was developed with the understanding that the machine is in otherwise good operating condition. Refer to the index at the back of this manual for Chapter and Topic page references. BE SURE to exercise the MANDATORY SAFETY SHUTDOWN PROCEDURE (page 8), BEFORE making any adjustments or repairs.
