This presentation is a brief outline of everything needed to perform safe and effective wheel straightening. More detailed information on specific procedures can be found elsewhere on these Technical & Training pages.
Wheel Straightening Decision Flow Chart
This chart illustrates the controlled process that is now recognized by the Society of Automotive Engineers. It describes the exact steps that were used during the independent testing that met SAE performance standards. Critical procedures from initial inspection to marking are shown in a step-by-step GO/NOGO process. Knowledge and understanding of this process is key to acceptable straightening.
Control of process is one of the benchmarks of SAE standards. All repair personnel are responsible for their services. Professional repairs are always traceable and the service professionals must be held accountable for their actions. The method of marking is up to individual policy as long as it is traceable back to the repair facility. This page gives examples of acceptable marking protocol.
Fluorescent dye examination under an Ultra Violet light is the industry standard for crack detection. It is used in automotive parts testing, and Boeing uses this method to examine aircraft engine turbine blades. Proper understanding and use of this test is one of the requirements of the Society of Automotive Engineers.
Heating is the single most critical factor in wheel straightening. Improper heating can irreparably damage a wheel. Some essential facts are presented in this downloadable document.
Proper Use of Impact
Using impact is an effective process in wheel straightening, if done properly. Impact should be applied while the bent area is under hydraulic pressure. But that situation can be dangerous so care must be taken. This document illustrates the technique of using impact appropriately and safely.
Measuring a bend accurately can be difficult. This information explains how to measure the depth and width of bends easily and accurately. The bend to depth ratio is also explained, which establishes the recommended acceptance criteria for wheel straightening. The criteria, shown as both chart and equation, confirm that the width of the bend should be at least 14 times the depth or the wheel should be disqualified for straightening.
Quality Assurance Reports Explained
Click on the PDF below for instructions on how to properly complete the above form. The report contains essential information that is a demonstration of transparency and integrity. Depending on the severity of the repair this report can be filled out in just a few seconds.
Quality Assurance Reports
Download a copy of this report and have them printed in two-part carbonless. One copy should be given to your customer along with your invoice and one copy should be maintained in your files.
Temporary Repair Labels
Download the format for some repair labels. If you intend to mark your wheels with labels, these samples can be used until you have an opportunity to print your own. You can use this format with Avery Template 8163.
Watch a video of the original SAE testing done by Independent Test Services originally for NBT Global, now NewArc Tech, LLC. The controlled straightening procedures recognized by the Society of Automotive Engineers, which are also described in detail on this website, were used on all wheels tested.
SAE Technical Paper
If you find a bent wheel on a customer's car, it is important that they know the following. Recent scientific testing, published by the Society of Automotive Engineers, proved that a bent wheel (even a very minor bend) is likely to crack with continued use. And, more importantly, your company can repair the bend and restore the wheel to a condition where it will not crack. Ours patented process is the only wheel repair published and accepted by the SAE. View the Full SAE Report.
Engineering Technical Paper
This paper was written principally for automotive engineers. The manuscript presents scientific facts about the most common aluminum wheel currently being used in the automotive industry and how our wheel straightening process takes those facts into consideration. The paper was composed by Ken Archibald, distinguished expert on wheel technology and testing.
Aluminum Wheel Basics
As a wheel repair specialist, you should be aware of some essential wheel basics. Should you be asked for recommendations or advice from your customer, you must be capable of providing information accurately and professionally.
Bolts and Torque Specs
A professional wheel straightener should have a basic knowledge of U.S. bolt grades and torque specifications. This document is a great quick reference guide.
Reading a Dial Indicator
Reading a dial indicator is not difficult, but even a seasoned user can hastily interpret the readings incorrectly. This will not only result in improper application of straightening pressure, but it could damage the wheel even further. The information in the document is essential for beginners, and serves as a good review for veteran wheel straighteners.
Wheel Straightening Manual for Review and Downloading
The latest edition of the NewArc™ machine manual in PDF format. This manual contains detailed information on safety, setups, techniques and other procedures, including machine care and maintenance. Everything you need to know to optimize the use of this machine is included. Take advantage of the PDF search feature to quickly find information specific to your needs.
Actual Wheel Straightening Sequence Demonstrated
This slide presentation explains the exclusive and patented NewArc™ process. It will clarify why our machine is the only one capable of wheel straightening repairs recognized by the Society of Automotive Engineers.
The Proof is in The Pressure
This short slide presentation clearly illustrates why the patented and exclusive Dual-Axis Strain Relief straightening process is the only one recognized by the Society of Automotive Engineers. This explanation proves the superiority of this method because it is the only one that can achieve the maximum possible strain relief.
Mounting a Wheel and Tire Assembly
The proper method of mounting a wheel without tire removal is demonstrated in this slide presentation. A standard Dual-Axis straightening setup is illustrated, and integral bead breaking using the same hydraulic tools used for straightening is also presented.
Problems will arise occasionally when straightening a wheel, but most are easy to solve. This document describes the three most common problems to keep an eye out for and the simple fixes associated with them.
This downloadable document will explain the straightening methods we recommend. We explain the process used on both Euro Flange and MC Flange wheels. We illustrate both Single & Double axis methods and offer helpful hints as well. These explanations will assist you in becoming a confident and effective wheel straightening professional.
