If the gang is excessively loose it may be necessary to completely disassemble the entire assembly
and clean the mating surfaces between the spools, bearings, end washers and disc blades.
□ If it is necessary to remove and disassemble the gang assembly, use suitable lifting devices and
supports to prevent injury.
With the disc lowered to the ground, first remove the scrapers and then unbolt the bearings from
the bearing standards. There are four bolts holding each gang assembly to the gang bar. Once
the bolts are removed, raise the disc high enough to either roll or pull the assembly from under
the disc. Block the gang to prevent it from rolling. Remove the nut locks from both ends of the
assembly. Use one wrench to keep the gang from turning while using the other wrench to tighten
the nut at the opposite end of the assembly.
It may not be possible to properly tighten the gang if dirt, grit or debris has built-up between the
components. In this case remove a nut from one end of the axle, slide off the end washers,
bearings, spools and disc blades. Thoroughly clean the mating surfaces between the
components and reassemble on the disc gang (see assembly section). Clean the threads on the
axle and in the axle nut. Apply an anti-seize compound to the axle threads and reinstall the nut.
Tighten the nut and reinstall the nut locks. Place the assembly under the disc and bolt to the
gang bar bearing standards. Occasionally turn the gang while tightening the bolts to check the
gang turns freely. Retighten the bearing bolts after the first 10-12 hours of operation.
Assembly Safety
□ Wear proper attire when assembling disc. Always wear relatively tight and belted clothing to
avoid entanglement in equipment. Wear sturdy, grip work shoes and protective equipment for
eyes, hands, hearing and head.
□ Handle the disc gang components with care during assembly. The disc blades are sharp and can
cut hands, feet, etc.
□ Disc blade assemblies and disk weldments and components are heavy and awkward. Two-
person assembly is recommended. When working with others, try to maintain visual contact and
communicate actions and procedures which may present a danger to them.
□ Read assembly instructions thoroughly before beginning.
□ Use the proper tools and equipment for assembly. Make sure you understand the safe
procedures for the motorized equipment and lifting devices you will be using. Make sure tools
and equipment are in good repair.
□ Use proper supports for the job and chock tires or any other components that could roll
inadvertently.
□ Purge air from hydraulic systems before operation. After connecting the hydraulic lines, carefully
cycle the hydraulic cylinder several times to purge air from the system. Visually check all
connections for leaks.
□ Never use your hands to check for hydraulic leaks.
