Illustrations of how to mount a wheel and tire assembly on the 30" swing SRS2 aluminum machine.

1. The photos on the following pages show how a wheel and tire assembly can be quickly mounted on the 30”
swing SRS 2 machine. The assembly can then be easily configured to perform the dual-axis straightening
process. The NewArc™ machine is the only device capable of this patented method, which is now exclusively
recognized by the Society of Automotive Engineers. For best results on bends requiring the maximum
allowable heat, the tire should always be removed.

2. The basic machine is light weight and takes little floor space. It can easily be secured to the
floor of any mobile unit, as shown here bolted to a pallet. This wheel to be mounted for
straightening has a 25” swing with the tire on. Although tire-on straightening is possible with
this machine, it is best to remove tires on wheels having more severe bends. 2 of 19

3. The first step is to remove the Bronze Bushing and raise the Swing Arm. Friction hinges in the
Swing Arm construction will hold it in any position.

4. Next, lower the wheel and tire assembly over the Mainshaft and align the bolt holes with the
slots on the Mainshaft Platen.

5. Install the Centering Cone. Pushing the cone in place, ensures that the wheel is positioned on
its center axis in the same manner as when it is on a vehicle.

6. Once the bolt holes are aligned on the Mainshaft Platen, three Mounting Bolts can be dropped
into place. Then attach the washers and nut on the underside of the platen. Leave them only
finger tight until the Mainshaft Spanner Nut can be installed and tightened.

7. Install the Mainshaft Spanner Nut and spin it into place.

8. Tighten the Mainshaft Spanner Nut.

9. Tightening the Mounting Bolts on the underside of the platen secures the wheel in place.

10. Tip the assembly out of the machine frame.

11. Tip the assembly out of the machine frame and remove the Lower Module from the bottom
of the Mainshaft. It will be reinstalled on the opposite end of the assembly.

12. Turn the wheel assembly around and install the Lower Module back on the Mainshaft.

13. Stand the Mainshaft back up, install the Press Platen, lower the Swing Arm and reinstall the
Mainshaft Bronze Bushing. Now the machine is ready for straightening setups.

14. The lower axis can now be installed with our custom ram extenders. If the bend is only
minor, one axis may be all that’s necessary. It is up the operator’s discretion.

15. If a second axis is desired, it can easily be installed at whatever angle the operator chooses.

16. It takes very little hydraulic pressure to keep the rams in place. They can easily be readjusted
to the exact position the operator chooses. From there the angles can be varied and the
rams can even be adjusted into separate planes.

17. Independent and alternating pressure with the dual-axis method is applied to achieve
maximum strain relief. This massaging action is much gentler on the damaged metal. This
method is so effective, little or no heat is necessary for minor bends.

18. If heat is needed, the amount that can be applied to the bent area is limited with the tire on
but a little more can be used if the tire bead is broken down. This can be done while the
assembly is still mounted in place.

19. Once the bead is broken, additional heat can be applied to the damaged area. From there, if
it is determined still more heat is still needed, the tire should be removed.
