Toronto, Ontario — April 10, 2018 — In a recent video from Collision Hub, Car-O-Liner and I-CAR experts teamed up to discuss how to properly interpret tolerances when it comes to autobody measurements, reports Repairer Driven News.
While most measurement tolerances have a certain amount of wiggle room, understanding exactly how much is crucial in order to correctly repair the vehicle, say the experts.
According to Car-O-Liner Training Academy manager Mike Hoeneise, many repairers mistakenly interpret tolerances. A typical tolerance is 3mm, but repairers often think “’If I’m within 3 mm, I’m good,’” said Hoeneise. He goes on to say that if one measurement is +3 and another is -3, there is a true difference of 6 mm and the repairer has exceeded the tolerance by 3mm. He insists that every component on the vehicle should be within 3 mm.
Hoeneise also discussed in the episode the difficulties advanced driver assistance and safety systems bring to measurement tolerances. Even when equipped with the OEM-specific repair procedure, oftentimes they don’t include exact measurements for the ADAS. In a case like this, Hoeneise advises repairers to “check the components around it.” If they are in the right place, the ADAS likely is as well.
When confronted with an incorrect measurement, Hoeneise says repairers need to be open to the idea that the error came from them. Sometimes this is due to selecting an incorrect data sheet or simply reading the measurement wrong. He advises techs to keep an open mind and retrace their steps, ensuring they have the correct data and tools to perform the measurement.
