When operating in severe conditions or high yielding corn (high pulling header load), grease fitting at 12 o’clock position, 5 - 8 pumps every 10 hours. Excess grease will purge from under spring.Grease fitting at 2 o’clock position, 2 - 3 pumps every 10 hours. Over greasing this fitting can allow grease to purge on belt and cause belt failure.

When operating in normal conditions, grease 12 o’clock fitting , 10-12 pumps and 2 o’clock fitting 5-8 pumps every 50 hours. After greasing, cycle variable sheaves through speed range a couple of times to ensure grease spreads evenly over cam surfaces. ( cycle sheaves during sickle header usage)

John Deere TY25744 Synthetic Grease is available for feeder house reverser drive gear case sheaves but not necessary if lubricated daily with TY6341.

Variable Speed Feeder House Reverser Drive Gear case sheaves - Turn sheave so fittings are in the 12 and 2 o’clock positions.

• Maintain 1/8” gap between sheaves at reverser spring loaded drive sheave, (feeder house variable speed drive slowed down completely) (see next page on adjusting sheave gap)

• Run through variable speed range of feeder house drives once a day if operating rigid/flex headers. Make sure variable speed is slowed back down before operating flex/rigid heads to prevent knife drive failures.

• If operating corn header increase running thru speed range to several times per day to insure grease spreads on internal cams evenly.

During Corn Harvest, run the back shaft at a faster speed. Running faster back shaft speed reduces the torque loads and heat levels which willLESSEN belt slipping and INCREASE the torque sensing efficiency. This may require slowing the corn head down to a under drive or 1:1 driveratio in order to maintain the desired ground speed.

* Preventing feeder house drive belt failures*

Adjusting reverser sheave gap

1. Maintain variable speed feeder house belt idler in slot within one inch of upper support bracket to prevent bending and breaking of drive idler mounting under high loads.

*** Adjust reverser sheave gap with upper variable sheave by loosening three sheave support to feeder house frame bolts, using upper variable sheave adjustment rod push or pull upper sheave support to maintain 1/8” sheave gap in reverser sheave. (rolling feeder house variable speed belt around sheaves while adjusting will give more accurate results. Run feeder house and check adjustment results.

Customer states that while harvesting small grains the machine is operating with high tailings, high losses, and may have a poorgrain tank sample.Problem or Situation : The 9870 machines are fitted with a front chaffer extension (FCE), while harvesting in certain small grain conditions the FCE can contribute to the symptom.Solution : A) First step is to ensure that the concaves are leveled and zeroed. What this means is that the concaves run true to the rotor and that the concave clearance reading in the cab is accurate. This is often overlooked by customers, and can change over time and with wear. Every time concaves are replaced it is recommended that they be re-leveled and zeroed. See the Operator and/or Tech Manual for doing this work. If the measured displacement was significantly different from what was read in the cab, a concavedisplacement calibration may be required also. See Operator and/or Tech Manual. It is assumed that narrow spaced small 31 wire concaves have been installed in the machine.B) While checking the concave level in step B, also look at the rotor elements for excessive wear and or damage. Elements that areworn will not thresh as well as those with sharper edges. If needed, replace elements in sets of three as they are sold in the kits, doing this will maintain rotor balance.C) The next step to confirm is the shoe settings and again confirming that the measured displacement is what the cab readout indicates. If not, adjustment is required along with a factory installation calibration. Reference Tech Manual for proper measurement, adjustment and calibration.D) When conditions permit place both the feed accelerator on low speed, as well as the feeder house drive chain on either the 22or 26 tooth sprocket (smaller sprocket), to help reduce excessive material other than gain (MOG) generation, and breaking up thecrop. If the above items have been checked and confirmed the next steps should be performed in the field to modify machine settings toreduce tailings levels.Start harvesting and with the recommended in cab / out of cab machine settings/adjustments, if you are still seeing the issueperform a few good power shutdowns to determine what adjustments are required to even out the material distribution from the conveying auger bed and return pan. It's important to keep the distribution from both the return pan, and conveying auger bed tocleaning shoe as even as possible. When looking across the conveyor augers and front chaffer, the distribution should look like a frown with the material heavier in the middle and lighter to the outside. This way we are not increasing tailings and decreasing the grain savings ability. You can achieve this by the installation of separator blanks, to even out the chaff load across the return pan and adjusting the conveying auger bed dividers.If excessive free grain is seen in the tailings open the sieve while still obtaining an acceptable grain tank sample. Note: Excessively high fan speeds (especially in combination with tight sieve settings) can blow grain in the tailings. However if very little grain is found in tailings and tailings levels are still higher than desired, increase the fan speed. As a general rule the cleaning fan speed on

Complaint or Symptom : Difficult to set and / or optimize machine performance in white cap conditions.Problem or Situation : White caps are present in the grain tank.High tailings levels and / or plugging of tailings.Solution : A) White caps are the unthreshed / broken heads of grain that end up in the grain tank. Removing these may require additional components to be installed in the separator. B) First step is to ensure that the concaves are leveled and zeroed. What this means is that the concaves run true to the rotor and that the concave clearance reading in the cab is accurate. This is often overlooked by customers, and can change over time and with wear. Every time concaves are replaced it is recommended that they be re-leveled and zeroed. See the Operator and/or Tech Manual for doing this work. If the measured displacement was significantly different from what was read in the cab, a concavedisplacement calibration may be required also. See Operator and/or Tech Manual. It is assumed that narrow spaced small 31 wire concaves (NSSW) have been installed in the machine.C) While checking the concave level in step B, also look at the rotor elements for excessive wear and or damage. Elements that areworn will not thresh as well as those with sharper edges. If needed, replace elements in sets of three as they are sold in the kits, doing this will maintain rotor balance.D) The next step to confirm is the shoe settings and again confirming that the measured displacement is what the cab readout indicates. If not, adjustment is required along with a factory installation calibration. Reference Tech Manual for proper measurement, adjustment and calibration.

E) If the above items have been checked and confirmed the next steps should be performed in the field to modify machine settings to reduce the white caps.F) To prevent the grain heads from breaking up before getting to the rotor it is suggested to run the feed accelerator on low speed and the feeder house conveyor chain on the smaller sprocket. If the machine was equipped with a 10 wing Tough Crop feed accelerator, it may be suggested to remove it and replace with BH81489 which contains the standard wings and grain wear strips.G) Addressing white caps should be done in the separator and not in the tailings system, hence steps B and C to confirm the separator.

It is recommended to start with concave covers (or blanks) to be installed (BH84534). These covers will prevent grain from falling through and allow the rotor to do additional threshing on the material before it falls down to the conveying auger bed. Start with the first concave then move to the middle of the mid concave which is where tailings returns to the separator.

Settings, it is recommended to run the rotor at maximum speed (1000+ rpm) to get as much threshing as possible. Setting the concave to a clearance less than 5mm should also be a good starting place, dialing this down to 0mm on a properly leveled and zeroed system is not uncommon and may be required. Start with a high fan speed and slow it as necessary check losses and slow fan speed if excessive grain is exiting machine in the chaff. Slow fan speed down if losses are high and grain is blowing out the back of the machine.

36

J) Conduct power shutdowns with each set of settings changes to get a full picture of what is happening in the separator. Instructions on how to conduct a power shutdown can be found in the STS Combine Adjustment Guide slide card. Look at shoe load; It's important to keep the distribution from both the return pan, and conveying auger bed to cleaning shoe as even as possible. When looking across the conveyor augers and front chaffer, the distribution should look like a frown with the material heavier in the middle and lighter to the outside. This way we are not increasing tailings and decreasing the grain savings ability. You can achieve this by the installation of separator grate cover blanks, to even out the chaff load across the return pan and adjusting the conveying auger bed dividers. The sectionalized concave covers should only be opened up if adequate threshing is achieved.K) If white caps still exist, the next recommendation is to install concave interrupters (AH202021) to the first concave while keeping the covers installed. Reevaluate the white cap condition by harvesting and making a power shutdown to look at distribution and how much threshing is taking place. Be mindful of tailings levels while running through the field and keep the fan speed up. If white caps are still present in the tank tighten the concave up to 0mm and evaluate again.
