    IX. REMOVING IMPACTOR F/ CART FRAME To service the Impactor, it is necessary to remove the Impactor from the Rolling Cart. The following Instructions cover the complete and correct method of performing this operation refer to SECTION XIII: Impactor Exploded View. These Instructions detail complete repair of the Impactor and its component parts.
  • Page 14 CAREFULLY remove Hub Sleeves, one at a time, from the Frame. The Impactor can now be moved to a clean, sturdy workbench to be disassembled for required maintenance and/or repair. To reinstall Impactor into Cart Frame, reverse the above procedure making sure the Impactor's Head Handle is positioned between the Frame's rear parallel Tubes.

  • Page 15: Disassembling The Impactor

    X. DISASSEMBLING THE IMPACTOR To disassemble the Impactor refer to Section XIII: Impactor Exploded View while completing the following steps: Remove six (6) Bolts [21] from Head Cover [33] and Motor Casing [20]. Separate Head Cover [33] from Motor Casing [20]. Remove eight (8) Bolts [2] from Hammer Casing [1] and Motor Casing [20].
  • Page 16 It may be necessary to apply heat to the Reverse Lever [36] as Locktite adhesive is used to secure the Reverse Lever Set Screw [39]. IMPORTANT Remove Reverse Valve Cover [34] from Head Cover [33] (heat may need to be applied). Reverse Valve [35] can only be removed from Reverse Valve Bushing [41] in one direction.

  • Page 17: Parts Inspection

    XI. PARTS INSPECTIONS When the GO-A13-HA Opener is in-for-maintenance and the Rolling Cart and Impactor have been disassembled (partial or complete), the components should be cleaned and inspected for wear before lubricating and reassembly of the Opener. Proper maintenance of equipment often depends upon the ability of a service technician to determine whether a part or assembly is worn to the point where it should be replaced.
  • Page 18 Installation of an air filter/dryer in the air supply line is the best method for reducing grooving and scoring of the cylinder. PN: 82-10420 is recommended. IMPORTANT A badly scored Cylinder cannot be restored to usefulness by honing. Enlarging the inside diameter widens the seal point between the Rotor and Cylinder to a degree that will hinder the operation of the motor and will result in loss of speed and power.
  • Page 19 The CYLINDER PLATE BEARINGS [25] provide a low friction support medium for the Rotor. To check the condition of a Bearing, hold the inner race and rotate the outer race by hand. If rough movement or substantial side play are detected, replace the Bearing. It is also possible to compare a used Bearing with a new one to detect the amount of wear.
  • Page 20 After the parts have been cleaned, inspected or, when needed, replaced, they should be wiped down with high quality air tool oil like WORKMASTER Tool Lube (PN: 36-21010) used in the Lubricator. The addition of the oil leaves a rust or moisture preventive film on the parts.
  • Page 21 The TWIN HAMMER MECHANISM of the Impactor is a highly effective design that delivers more power per pound and is less sensitive to air pressure fluctuations than any other design. Two Hammers strike instantaneous balanced blows to the Anvil's lobes generating powerful torque with minimal vibration.

  • Page 22: Reassembling The Impactor

    XII. REASSEMBLING THE IMPACTOR Once the Impactor's internal components have been inspected, repaired or replaced, the Impactor can be reassembled. The reassembly of the Impactor is essentially the disassembly instructions in reverse order. Refer to Section XIII: Impactor Exploded View during reassembly.
  • Page 23 Before installing Impactor into Cart Frame, operate Impactor for a short period (3 to 5 minutes) of time to test for proper operation. Check the free speed at the Anvil [10] with a tachometer. Speed is 1500 RPM (approx.) at 85 PSI using 150 CFM (approx.). Never substitute wire, nails, welding rod, etc for retaining pins or fasteners because they are dangerous if thrown from the unit at free...
