3.2.3. Install Distance Measuring Indicator
The collet grips the wheel nut as the collet bolt is tightened.
Failure of a collet may result in damage to the DMI components.
Thoroughly remove rust and dirt from each wheel nut. Replace
damaged or corroded wheel nuts.
To install the assembled DMI on the vehicle perform the following:
5. Slip collets over wheel nuts (Figure 7).
6. Use circular grooves etched on universal hub adapter so that collets are equal distance
from DMI encoder shaft; off-centre placement of universal hub adapter will increase data
noise and cause excessive mechanical vibration.
7. Apply thread-lock compound to collet bolt threads prior to insertion. For successful
bonding, knowledge of adhesive characteristics is essential.
Over tightening of the collet bolts may result in thread stripping.
Under tightening of the collet bolts may result in a poor
mechanical connection and subsequent damage to the DMI
assembly.
8. Tighten collet bolts in a uniform manner using supplied
