BOLT TORQUE

READ THESE INSTRUCTIONS FIRST:

1.Improperly tightened bolts will result in damage, breakage, expense, and down time.

2.Always replace bolts with the specified grade and type.

3.Torque properly before first use of the machine and every 2-4 hours of use until you are sure bolts are staying tight.

4.The chart below is a guide for proper torque. Use it unless a specified torque is called out elsewhere in the manual.

5.Torque is the force you apply to the wrench handle or the cheater bar, times the length of the handle or bar.

6.Use a torque wrench whenever possible.

The following table shows torque in ft. lbs.

ASSEMBLY INSTRUCTIONS

WARNING: Never work under the toolbar while in a raised position without using safety lockups.

WARNING: Use extreme caution, the blade is sharp and may cause bodily injury.

The 30” coulter that are mounted on 12” spacing will need to be completely assembled before mounting to the toolbar.

NOTE: To aid the assembly of the opener, it is recommended that a stand be constructed to temporarily attach the opener and hold it in an upright position.

CAUTION: The coulter and its components are very heavy. Extra attention to lifting techniques while handling and or maneuvering the coulter during assembly is very important. Failure to do so may lead to personal injury or death.

STEP 1. Attach the 2986-111 hub assembly and 2986-318 hub cap retainer to the 2986-106 main arm assembly using (4) ½” x 1-1/2” hex head bolts. This step will determine right hand or left hand coulter assembly.

ASSEMBLY INSTRUCTIONS

STEP 2. Attach the 2986-211 Rear Knife Arm to the 2986-111 hub assembly using (4) ½” x 1-1/2” hex head bolts. Make sure that the mount for the knife is on the same side of the arm as the spindle/blade.

STEP 3. Attach the 2986-213 Closing System Mount to the 2986-211 Knife Arm using (2) ½” x 3” hex head bolts and (1) ½” x 1 ½” hex head bolt and ½” hex lock nuts.

STEP 4. Attach the 2986-212 Closing System Adjustment to the 2986-213 Closing System Mount Bracket using (2) ½” x 1 ½” hex head bolts and ½” hex lock nuts.

ASSEMBLY INSTRUCTIONS

STEP 5. Attach the 30” blade 2571-205 to the 2986-111 hub assembly using (6) ½” x 1 ½” plow bolts and ½” hex lock nuts.

NOTE: The blade must be centered on the spindle. Bolts are to be just slightly tightened. At STEP 7 they are to be tightened securely and torqued to 90-96 FT/LBS.

STEP 6. Attach the Avenger Knife 2986-214 to the Knife Arm 2986-211 using shims as needed to align the knife point with blade and using (2) ½” x 2” hex head bolts, hardened flat washers and ½” NIF-LOK nuts.

STEP 7. Center the blade on the spindle, check by rotating blade and watching clearance between knife and blade. Move the blade on the spindle as required until the blade runs concentric. Tighten (6) ½” lock nuts, torque to 90-96 ft/lbs. THE BLADE MUST RUN CONCENTRIC.

STEP 8. Adjust knife clearance to blade as close as possible. The high point of the blade should clear the knife no more than 1/64” max. as the blade is rotated. The blade should rotate freely. Tighten (2) ½” x 2” hex bolts to 120 ft/lbs. Re-check clearances by rotating blade one full revolution after all bolts are tight. Lock the knife in place by using the 5/8” x 2 ½” setscrew and 5/8” hex jam nut to prevent the knife from moving rearward.

KNIFE ADJUSTMENT

The adjustment of knife clearance to the blade is critical to trouble free operation of the coulter, in certain conditions the coulter can “plug” in just a few feet if not correctly adjusted.

1.The disc blade must run concentric. Adjust by loosening six hub nuts and centering the blade.

2.Set knife to rub slightly on blade, especially at bottom of knife. See illustrations above. Tighten NIFLOK nuts to 120 ft/lbs. by using the wrench on both the bolt head and the nut.

3.Adjust the 5/8” x 2 ½” bolt down against the stop of the knife to lock the knife in place, tighten the jam nut to secure bolt.

ASSEMBLY INSTRUCTIONS

STEP 9. Attach the 6200-201 Closing Wheel Bracket to the 2986-212 adjustment bracket using (2) ½” x 1-½” hex head bolts and lock nuts. NOTE: Securely tightening the bolts at this step is not necessary because the infield height adjustment will be done later for proper operation of the closing system.

STEP 10. Assemble the 6000-002 Close Wheel Kit as shown in illustration below.

STEP 11. Attach the 6000-002 Close Wheel Assembly to the 6200-201 Close Wheel Mount Bracket by first inserting the hook of the spring through the hole of the mount bracket then use (1) ½” x 6 ½” hex head bolt, eccentric bushings and ½” lock nut.
