Plunger Adjustments

The plunger can be adjusted to remove both side and up/down play. It is important to keep the plunger in adjust-ment to avoid unnecessary wear.

Before adjusting the plunger, make sure the connecting rod is connected to the plunger and bullgears.

Adjustments:

1. Turn off control system and lock out power supply to the machine before making any adjustments.

2. Remove knife guide shown in Figure 6 page 4. Clean debris from area then re-install knife guide in its fully retracted position (as far right as possible).

3. Remove stationary shear bar shims that are shown in Figure 6 page 4 and re-install stationary shear bar.

4. Lower plunger rollers shown in Figure 4 to their lowest point, then pry plunger up. Secure plunger so it wont drop.

5. Loosen plunger slide bolts shown in Figure 4. Add plunger slide shim(s) so plunger slides protrude 1/8 below bottom of plunger as shown in Figure 5 page 6. Tighten plunger slide bolts, then lower plunger.

6. Pry plunger to right side of chamber.

7. Adjust upper plunger hard slides and lower plunger slides shown in Figure 4 so that the maximum clear-ance between the slides and the wear rail, at the nar-rowest point in the chamber is .032” - .045” clearance.Ensure all adjusting bolts are properly tightened.

8. Position plunger at shear bar intersection point as shown in Figure 6 on page 4. Pry plunger to left side of chamber.

9. Adjust knife guide shown in Figure 6 so there is .032 - .042 clearance between the knife guide and plunger knife using the 1/2” x 1 1/4” square head screw closest to the front of the baler as shown in Figure 6. Adjust the rear 1/2” x 1 3/4” square head screw until it firmly contacts the knife guide. Tighten the rear square head screw.

Tighten the 5/16” x 1 3/4” flat head machine screw shown in Figure 6. The first nut is only tightened enough to hold the knife guide against the square head screws. Hold the first nut from rotating and tighten the

second nut firmly, approximately 17 foot pounds. The forward square head screw is to be firmly tightened.

10. Check the knife guide with a straight edge to see that it remained flat, and is not bowed. Repeat step 9 if the knife guide is bowed.

11. Pry the plunger to the right so the plunger rests firmly up against the knife guide as shown in Figure 6. Measure the clearance between the plunger knife and stationary shear bar. The clearance should be at least 1/16 from top to bottom and no more than 1/8”. Add shims behind stationary knife if needed.

12. Adjust plunger rollers at the narrowest part of the chamber so the rollers firmly touch the top rails. Tight-en mounting hardware.

DANGER: SHIELDS ARE FOR YOUR PROTEC-TION. ALWAYS HAVE SHIELDS IN PLACE BEFORE STARTING OR OPERATING THE BALER.

Plunger Safety Latch

If the needles are obstructed by foreign material in the nee dle slots, foreign material in the chamber, or if the needles prematurely enter the chamber because of early timing, needle breakage can occur.

The plunger safety latch “A,” Figure 7, helps protect the nee dles against breakage. If for any reason the needles re main in the bale chamber while baling, the plunger is stopped by the plunger stop dog and the fl ywheel shear bolt is sheared.

Before replacing the fl ywheel shear bolt, always pull the stop dog out of the bale chamber. Do this by pulling the needle yoke back to the home position. The safety latch is adjusted by lengthening or shortening the latch rod at “B,” Figure 7. As the needles are leaving the bale chamber and the tips of the needles are even with the bottom of the bale chamber, adjust the length of the latch rod so that the plunger stop dog “A” in Figure 7 is just leaving the chamber and is fl ush with the inside of the dog plate.

Figure 7 - Plunger Stop Dog

Check these adjustments closely and run the plunger back and forth by hand to insure the knives are properly ad justed. Using a bar force the plunger to the right side of the chamber with great pressure to insure the knives do not lock up.

Pinion and Bullgear Adjustment

The fl ywheel should be parallel to the frame plus or minus 1/8", with pinions meshing evenly with the bullgear teeth (“A,” Figure 8).

The lash of the pinion gears should have between 1/8" and 3/8" of free play on the rim of the fl ywheel at “B.” Measure this when the connecting rod is fully extended and blocked to prevent bullgear movement.

To correct excessive free play, adjust set screws “C,” Fig-ure 8. Be certain both sides are adjusted evenly to avoid serious equipment damage.

Figure 8 - Pinion and Bullgear

Bullgear Luber

The bullgear luber, Figure 9, distributes bullgear grease onto the bullgears through a manifold under the bullgear hood.

Prior to initial baler operation the bullgears require a complete coating of lubricant (Freeman bullgear grease, F000007626, only). Allow 4 hours before fi rst using the baler, after completely covering the bullgears with grease. During the next 48 hours of bailing, grease bullgears every 30 minutes, and again at the end of the shift. Greasing at the end of the shift gives the bullgear grease an opportu-nity to set up and adhere to the bullgears. Once you have established a good coverage of grease on the bullgears, greasing every four hours thereafter is usually adequate; and always grease at the end of the shift.

While turning the fl ywheel, operate the lube pump handle to apply a coating of bullgear grease to the gears. This typically will require about 5 revolutions of the bullgears to get a full fi lm of lube covering the working surfaces of the gear teeth. This process should only be done by turning the fl ywheel by hand and not by running the baler with the engine or tractor.

Subsequent lubrication should be done at the end of the baling shift to allow the lube time to set up and minimize the “fl inging” off of the product.

System Pressure Adjustment:

The pressure is to be set at 800 lbs. when lever “D” Figure 11, is full forward. To achieve this pressure adjust, nuts “B.” Do not adjust the pressure without the proper gauge, and be cer tain that lever “D” is full forward when the pres-sure is read.

Figure 11 - Tension Control

Tension Control Pump Drive:

To tighten the tension control drive chain “A,” Figure 12, loosen the two bolts “B” that hold the tank to the mounting plate. Move the tank back until the chain has about 3/4" of slack up and down at the center of the chain. Retighten the bolts when the chain is at the desired tension.

Figure 12 - Tension Control Chain

Bale Length Adjustment

Bale length is adjusted by changing the height of the trip bar stop bolt “A,” Figure 13. Raising the bolt decreases bale length and lowering the bolt increases bale length.

If no more adjustment is available with the trip bar stop bolt, change the height of the meter trip bar stop “B.” Use the holes provided to adjust the meter trip bar. If the meter trip bar is moved, the meter trip bar bolt will need adjustment.

Feed Fork Timing

The feed fork, Figure 14 and 15, pulls product into the bale chamber. It is important to have correct feed fork timing to keep the feed fork and plunger from interfering with each other which may cause damage to the baler. The feed fork should be 2” away from the plunger face as it leaves the chamber (see Figure 15).

Follow instructions below for adjusting feed fork timing.

Knotter Settings

The following instructions will help you understand the Knotter system and the adjustments necessary to main-tain and keep the system tying at the optimum level of performance. Periodic checks of these adjustments will help alleviate tying problems and reduce the risk of equip-ment damage.

Note: Adjustments may vary for different crops.

Twine Finger

The twine fi ngers have two independent adjustments, fully extended and fully retracted. The extended position of each twine fi nger adjusts separately and is determined by the length of the twine fi nger drive rod. The fully retracted position of all the twine fi ngers is managed by a single stop bolt. (see Figure 20 page 9)

The twine fi nger fully extended position should be set with the needles in the home position (see Figure 16), with the twine fi nger drive cam holding the twine fi ngers extended. Needles are in home position when bolt “A”, Figure 16, is 1/4" to 1/2" past center between “B” and “C”. Before adjusting the twine fi ngers, ensure the twine fi nger drive shear bolt is tight and in good condition, not partially sheared (see Figure 20 page 9).

With light pressure applied at the tip of the twine fi nger, the fi nger should lie just at the rear edge of the twine guide. The proper adjustment should have the twine fi nger (see Figure 19 page 9) between fl ush, and protruding 1/8" past the twine guide.

To adjust the twine fi nger extended position (see Figure 17 and 18), loosen the jam nuts on the twine fi nger drive rod and rotate the rod clockwise to increase travel.

Note: The jam nut toward the front is left-hand thread and the rear is right-hand thread.

To check the twine fi nger retracted position, turn the knotter shaft with a wrench (see Figure 30 page 11) until the twine fi nger drive cam releases the cam follower. The fi ngers should retract far enough so that the tips are completely clear of the needle slot (see Figure 19 and 20 page 9).

Needle Alignment

Adjust your needle alignment when the needles are at TDC (top dead center). TDC is when the needles are at the highest point of travel. At this time the Needle Yoke Drive Rod is in the 11 o’clock position (see Figure 21).Adjust the needle alignment by loosening the bolts at the needle base and sliding the needle left or right as neces-sary (see Figure 24 page 10).

Figure 21 - Needles at TDC, left-hand view.

At TDC, the needles should be close to or make light contact with the knotter frames. Make sure there is no more than 1/16" gap between the needle and the knotter frame (see Figure 22). Light contact between the needle side and the knotter is actually preferred, and is accept-able as long as no more than a 3 lb force is required to move the needle away.

The needles may be bent side to side as needed, if the needles are centered in the bottom slots but the tips of the needles do not match the conditions described above.

Figure 22 - Needle/Knotter Clearance

The retracted position must be adjusted if the tip of any fi nger is hanging over the needle slot, or if all three fi nger tips are more than 1/8" from the edge of the slot. Adjust the retracted position by adjusting the twine fi nger stop bolt (see Figure 20) located just ahead of the twine fi nger drive shaft. A single adjustment affects both twine fi ngers.

Figure 25 - Needle Measurement

Adjust the amount of needle travel by turning the needle yoke drive rods attached to each end of the knotter shaft (see Figure 26). Loosen the jam nuts and turn each rod an equal amount in order to keep them equally loaded. Note that the upper rod end bearing has left-hand thread.

IMPORTANT: At TDC load on both needle yoke drive rods must be equal. If one is too tight and the other loose, adjust accordingly.

If the twine fi nger collides with the needle roller on the down stroke (or needle side near the roller) adjust the needle yoke drive rods shorter to raise the needle closer to 6 1/4" position at the instant the twine fi ngers activate.

Drive Rod

Figure 26 - Adjusting Drive Rods

Needle Height

The height of the needle is determined as it passes the twine fi nger while the tip of the twine fi nger is in the middle of the needle slot. (see Figure 23) The needles should be set such that there is 1/8" to 1/4" clearance between the needle and the edge of the twine fi nger at the clos-est point (see Figure 23). Take this measurement as the needles are on the upward stroke through the chamber top plate.

Bill Hook Twine Guide Clearance

Moving the knotter position affects the clearance of the bill hook over the twine guide plate, and the clearance over the twine guide plate will change.

The proper clearance between the twine guide plate and bill hook is 1/64" to 1/16" (see Figure 29) at the point of bill hook rotation which brings it closest to the guide plate.

Position the knotter with a wrench as shown in Figure 30 to check the clearance between the Twine Guide Plate and Bill Hook. Rotate the knotter shaft until the Needle Yoke Drive Arm is in the 12 o’clock position. (See Figure 31 page 12) This will rotate the bill hook above the twine guide plate. If any knotter on the baler has clearance less than 1/64", the knotter mounts should be shimmed. (see Knotter Mount Shimming Instructions on page 12)

Knotter Position

A properly positioned bill hook is essential for consistent tying. The proper position of knotter is determined by gauging the bill hook to the twine guide. Check the knotter position by turning the knotter shaft with a wrench until the bill hook is pointing straight forward. The distance from the front edge of the twine guide to the tip of the bill hook (see Figure 27) should be 5/8”± 1/16".

Knotter Mount Shimming Instructions

If the clearance between the Bill Hook and the Twine Guide Plate is less than 1/64", then you need to install Knotter Mount Shims. Install 1 shim (see Figure 32,33 and 34) under each knotter mount. Insure that the slots are pointing to the inside of the chamber, towards the knotter assembly.

Figure 32 - Left-Hand Knotter Mount

Figure 33 - Knotter Mount Shim

Figure 34 - Right-Hand Knotter Mount

Once the shims are in place and you have tightened the knotter mounts (torque bolts to 75ft lbs.), check the clear-ance between the bill hook and twine guide plate. Make sure the clearance is between 1/64" and 1/16". Add another shim to each side, if needed.

Bill Hook Trigger

There is one adjustment for setting the Bill Hook trigger tension. If the bill hook trigger is too tight, the knot may stay on the Bill Hook and the twine may break. If the trigger is too loose, the tail of the knot may release to early and will knot form a good not. To adjust the trigger tension, turn the nut to compress the spring to a length of 15/16" (see Figure 37).

Twine Holder

There are two adjustments for setting the twine holder tension. The Tying Holder Bolt controls how fi rmly the twine is held while the knotter is turning, the Bale Forming Bolt controls how fi rmly the twine is held while the bale is being formed. (see Figure 35 and 36)

Adjust the Tying Holder bolt such that the end of the spring is even with the end of the spring gauge (see fi gure 35). This adjustment will vary slightly with different grades and sizes of twine. This setting may be too tight if you notice excessive twine strands building up in the twine holder. Material in the holder will affect tying, keep the holders clean.

Tying Holder Bolt

Spring Gauge Roller Contact

Lever

Figure 35 - Tying Holder Bolt

To set the Bale Forming tension, fi rst remove all twine from the twine holder (see Figure 36). The bale forming tension is set by loosening the jam nut and turning the Bale Form-ing Bolt C.W. until it just contacts the leaf spring. Turn the bolt 3 to 4 additional turns to compress the leaf spring. Remember to tighten the jam nut. Because of variations in leaf springs, the bolt settings may differ visually from one knotter to the next. This adjustment must be made with no twine in the holder.

It is acceptable to increase the Bale Forming Bolt tension as needed, but it is important that the leaf spring com-pletely releases tension while the knotter cycles. After increasing the Bale Forming Bolt tension, always rotate the knotter shaft to make certain the Cam Lever releases tension with the Leaf Spring (see Figure 36) during the tie cycle.

2. Feed twine through twine tension assemblies.

It is important that the three twine tension assemblies (Figure 40) are adjusted so that there is a slight amount of drag on the twine. If the twine tensioner is too loose, the twine lashes out and the twine fi ngers are not able to grasp the twine, or both. If the twine tensioner is to tight, it may break or come out of the twine holder.

Twine Stop and Angle Spring

The twine stop spring must maintain slight pressure against the end of the twine guide plate. The twine guide spring helps hold the twine when the twine fi nger rotates around. If the spring is too loose, the knotter will not tie a good knot. If necessary, bend the stop spring as required (see Figure 38). The Angle and Stop spring help hold the twine while the bale is being formed.

When having a twine knotter problem, or miss ing a knot on one twine or an oth er, it is important to determine which twine is not tying prop er ly. The TOP twine is the twine that is being held in the knotter while the bale is being formed. The BOTTOM twine is the twine that the needle de liv ers to the knotter to tie the bale. When a mis-tie occurs you must locate the problem twine (Top or Bottom) and determine:

1. Is the end of the untied twine frayed, or squared cut?2. Is there any damage to the twine? Is it frayed along the length, frayed beyond the knot? 3. Is the twine long enough to wrap around the bale?4. Is there twine tangled in the knotter?

A majority of the time, the mis-tie is caused external of the knotter frame. Some things to always check before condemning the knotter are:

1. Check twine delivery from the twine box. Are the twine boxes correctly tied together so as not to obstruct free feeding?2. Is the twine properly routed to the needle?3. Ensure the twine guides and/or needles have no sharp worn edges.

KNOTTER TROUBLE SHOOTING4. Slack pullers must be properly threaded and operate freely.5. Twine tensioners are properly adjusted when the twine has approximately 4 pounds of pull, while the knotter is tying.6. Check hay dogs for proper operation, and or broke or missing springs. Hay dogs will wear and are very important. If unable to correct a twine fi nger mis-tie, it is possible that the hay dogs have worn and are not properly holding the end of the bale.7. Check bale weight/density. Too light of a bale may cause the knot to hang on the bill hook, and too heavy of bale can cause several different mis-ties (see chart below).8. Are all the necessary components in proper adjustments? Remember any time you replace or adjust a needle the twine fi nger must be checked and prob a bly adjusted at the same time.9. Next to the hay dogs, the twine fi ngers are important to keep in good operating condition. They cannot have excessive play in the pivot, and they must be free of any nicks or burrs that may damage the twine.

Following table includes the most common examples of failed knots with possible causes for, and possible rem- e dies. Refer to Figures 47 and 48 for the letters referenced in the chart starting on page 18.

PERIODIC MAINTENANCE OR LUBRICATION

At the end of the season, remove all material from the bale chamber and clean with compressed air. Pressure washing or steam cleaning is not ad-vised. Mois ture can create problems with electrical components by promoting corrosion. Any hay, chaff or dust on the baler will collect moisture during the winter and cause unnecessary rusting.

Check the baler for any worn or damaged parts. Replace and order parts from the dealer as needed.

Coat the bale chamber lightly with grease to prevent rusting.

Provide adequate protection from the weather.

It is good practice to have the baler inspected and reconditioned at the end of the season.
