Product Description:
The universal magnetic fall/trail gauge is a multifunctional axle gauge for motor vehicles with the following functions:
Features:
The adjustable spring end design is used, to return the spring leg to its original fall position after disassembly and reassembly of the suspension or to check the extent of the fall change, to maintain correct wheel alignment and prevent tire wear.
Robust magnetic measuring instruments enable fast and accurate measurements of fall and trail with scales in the range of +5° to -5° and a large adjustment button facilitates the zeroing of the Bubble during follow-up measurements.
Magnetic crash gauge wheel with grooves for secure grip when rotating to adjust the track start.
The powerful magnetic holder can be fixed to the wheel hub or brake disc for measurement.
Measuring angle:
The drop angle range is +5° to -5°.
It can measure the trailing angle. The measuring method consists in rotating the wheel by 20° from the front, placing the instrument against the wheel, adjusting the bubble so that it is away from the zero° mark, and then turn the wheel 20° in the other direction and read the Kingpin trailing angle.
Other functions:
Saves time, is inexpensive, easy to transport and delivers very accurate measurements.
Kingpin angle tool guide, the fall angle plays an important role in the tire side force, a positive fall angle can produce an automatic directional effect of straight steering.
To calibrate the gauge, clamp the dragonfly with the transverse dragonfly, place the magnetic side of the measuring instrument on the vertical side of the dragonfly and adjust the edge screws in this way, that the dragonfly of the measuring instrument is centered on the 0° mark.
This gauge can meet the tire positioning and repair requirements of various vehicles such as cars, SUVs and motorhomes, helping car owners and maintenance personnel to accurately adjust the wheel angle to ensure vehicle safety and normal tyre life.
