- Page 20 Step 14. Connecting the Lighting Cables Route the lighting cables as shown in the photos below and secure with cable ties. Utilize the loop clamps installed on module C to secure the cables. Be sure to test all light functions after the connections have been made.
- Page 21 Scorpion C-90 Installation: Flat Bed Mount Prior to beginning the installation, the host truck must be at its intended operating weight. The recommended weight range is between 18,000 and 20,000 lbs [8,165- 9,070 kg] however there is no upper weight limit. Any equipment that will be permenantly installed on the truck should be present or the truck should be ballasted to represent the additional weight.
- Page 22 Scorpion C-90 Installation: Flat Bed Mount Before beginning the installation, position the truck on solid level ground. The frame rail ends should be clean and square. Remove any electrical cables that could be damaged during the installation. Place a temporary ballast weighing approximately 3,000 lbs [1,360 kg] as close to the rear of the bed as possible.
- Page 23 Scorpion C-90 Installation: Flat Bed Mount Step 2: Install Bolts and Weld 4" x 9" Angles Take note of where welding on the angles and frame is required. Grind off the powder coating from the angles and frame as needed so that a clean weld can be applied. Attach the 4"...
- Page 24 Scorpion C-90 Installation: Flat Bed Mount Step 3: Position Backing Plate and Trim 4" x 9" Angles Measure approximately 12" [25mm] up from the ground and mark a cut line at the bottom of the 4" x 9" angles. Cut off the portion of the angles that extend below the line.
- Page 25 Scorpion C-90 Installation: Flat Bed Mount Step 4: Attach TMA to Check Ride Height Check that the assembled Scorpion C-90 TMA is level and is at the proper 12 inches [25mm] off the ground (see drawing 1000-169 for reference on measuring ride height). The C-90 truck side frame should also be level with the TMA. If it is not, make adjustments to the stop bolts to bring it level (again, see drawing 100-169).
- Page 26 Scorpion C-90 Installation: Flat Bed Mount Step 5: Check Ride Height of TMA Once the TMA is securely bolted to the truck, remove the temorary ballast on the truck bed. Raise all 4 of the jacks until the truck is carrying the weight of the TMA. Inspect the TMA to verify that it is reasonably level with the truck. Proceed to take ride height measurements as outlined in drawing 1000-169.
- Page 27 Scorpion C-90 Installation: Flat Bed Mount Step 6: Welding the Backing Plate Burn holes through the 4" leg of the 4" x 9" angles in line with the backing plate holes. Fully weld the backing plate in place. Grind off all slag and weld spatter adjacent to the holes.
- Page 28 21 October, 2019 TrafFix Devices Inc is the manufacturer of the Scorpion Truck Mounted Attenuator Model C-90 (TMA). TrafFix Devices Inc reviewed the installation of the C-90 Scorpion TMA for use in New Zealand and we have designed a mounting plate (reference drawing 11174 Rev B) to be suitable for mounting the C-90 to a host truck with an installation height of between 250 and 265mm above the ground.

- Page 30 Scorpion C-90 Installation: Flat Bed Mount Step 7: Attaching and Leveling the TMA Attach the TMA to the truck following the same directions in step 4. Use the eight (8) provided 1"-8 x 3" bolts, locknuts, and washers to attach the TMA. The bolts should be torqued to 250 ft-lbs [340 N-m]. Once the TMA is attached, remove the temporary ballast and raise the jacks.

- Page 33 Ride Height Adjustment: Scorpion C-90 Step 1. Position the TMA truck on solid level ground and lower the TMA to the fully deployed position. Measure the ride height at the rear diaphragm on both sides of the TMA. Both measurements must be 304.8mm +/- 25.4mm for the TMA to perform as designed.
- Page 34 Ride Height Adjustment: Scorpion C-90 Step 2. Raise the TMA to the fully stored position and verify that the locking latch has engaged. It is very important that the locking latch be engaged so as to prevent any unexpected movement of the TMA that could cause injury to workers. Loosen both jam nuts so the stop bolts may be adjusted. If the measurements taken in step 1 showed that the ride height was too high, turn the stop bolts clockwise which will lower the TMA.

- Page 36 Bearing Replacement: Scorpion C-90 Frame Step 1. Position the TMA truck on solid level ground and lower TMA to the fully deployed position. Lower the drop jacks until they hit the ground, then slightly raise the TMA until the next highest pin hole on the drop jack will align and reinstall the lock pin. Lower the TMA slightly until the drop jacks are carrying weight. Lower the drop legs on the front jacks to the lowest possible position and then begin cranking the handle until the wheels contact the ground.
- Page 37 Step 2: Disconnect Strut Power Cable Before the TMA can be seperated from the C-90 frame, the lighting power cable needs to be disconnected. Remove the screws and loop clamps identified in the photo below. Disconnect the the large power cable that connects to the truck and feed it back through until it is seperated from the C-90 backup frame (PN 11502-01).
- Page 38 Step 3: Seperating the C-90 Frame Once the strut power cable is clear and the weight of the TMA is being carried by the jacks instead of the pivot pins, the C-90 frame can be seperated. Remove the keeper pins from the pivot pins (PN 10939) and the cylinder clevis pins (PN 12015-3.375). Remove the pivot pins and clevis pins as shown below. Block the casters on the TMA so it can't roll away and then pull the truck forward far enough to provide room to work.
- Page 39 Step 4: Replace Worn Bearings 1 Remove the worn bearings (four total) from the vertical pivot plates on the backup. Use a wire brush to clean the bearing holes until all debris, dirt, grease, and residues have been removed and the surface of the steel is shiny. Inspect the condition of the bearing holes for any deformation, elongation, or wear. If there is any damage or wear present on the holes, please consult with the TrafFix Engineering department for assistance before proceeding with bearing replacement.
- Page 40 Step 5: Reconnecting the C-90 Frame Once the new bearings have been installed, back the truck up to the TMA and re-align the pivot axis. When reinstalling the pivot pins, be sure to also install the provided spacer washers (PN's 12001 and 12083). These are important as they occupy the extra space and prevent the bearings from walking out. Please note, the spacer washers may need to be installed differently than depicted, their orientation is dependent on the size and locations of the gaps.
