(G.3) Removing & Installing Mirror Plates
Your Mekra-Lang mirror system is equipped with a durable mirror plate assembly reinforced with shatter-resistant
adhesive to minimize splintering in the event of breakage. It is strongly recommended to immediately replace damaged
mirror plate assemblies.
If you have a heated mirror, be careful not to damage the wiring, or push upward on the heater foil terminals. Make
sure you pull or push on the wire terminal, rather than the wire itself.
Please note that the main glass plate and convex glass plate are removed in the same manner.
1. Actuate the mirror down by applying pressure
to the bottom edge.
2. Push the convex mirror up until it clicks out of
locking position.
3. Slide the mirror up and out.
This illustration shows the installation of the convex
mirror plate assembly. The steps are the same for the
flat or convex glass plates.
Where possible, use the remote function of the mirror
to place the socket plate in the extreme “down”
position in order to install the mirror plate as shown in
figure 5. Once the convex glass is actuated down
apply pressure upward in order to dislocate glass from
actuator teeth as shown in figure 5.

(G.4) Removing & Installing the Back Cover
Removal
In order to properly remove the back cover, it is critical that you first remove the mirror plates,
as explained in G.3.
After removing the mirror plates, remove the five bolts using a T-20 driver as shown in figure 7
below.
After removing the bolts gently apply pressure to the groove between the housing and back
cover with a flat screwdriver until the back cover snaps free.
Installation
In order to properly install the back cover remove the Main mirror assembly and convex mirror
assembly as per instructions in G3.
Tools Required: Drill, 7mm or ¼ inch drill bit, marker, and a scale or a measuring tape
Use the below template or measurements to drill the 7mm or ¼ inch holes on the bezel.

(G.5) General Maintenance and Cleaning Tips
1st surface glass has an exposed reflective surface and is not subject to corrosion. When cleaning 1st surface mirror glass,
abrasive cleaners or brushes should be avoided. Excessive abrasion may damage the reflective surface. All glass can be
scratched.
A standard glass cleaner and a soft, clean cloth should be used to clean the mirror surface.
(T.1) Adjusting Folding Bracket
Your Mekra-Lang mirror brackets are equipped with a fold-away feature, also known as the break-away system. The
mirrors will fold back either manually or spontaneously, with impact. This feature aids in minimizing damage to the
mirror system and vehicle door.
The brackets have rotating attachments that allow the fold
away function. The lower holder is designed to give the
bracket stability. However, the lower holder may sometimes
require adjustment.
Start by disassembling the lower holder. Remove the 3 bolts
from the holder and then remove the rubber spacer,
pictured in figure 9. This should expose the spring and allow
for break-away adjustment. If the break-away feature
requires too much force to fold back, loosen the nut above
the spring in the lower holder. Nominal setting for the
torque is _ N-m. When the detent is in the nominal
position, the detent spring should be almost fully
compressed.
If the bracket folds back too easily, however, take the
following steps to tighten the break-away function. The
upper holder should be torqued to 30 N-m. Tighten upper
fastener kit if found to be too loose. Check the torque at the
lower holder, which should be ~9 N-m in order to compress
the detent spring almost completely.

(T.2) Mirror Movement Analysis Flowchart –Western Star
1. Follow the flowchart above in order to promptly diagnose mirror movement problems.
2. Make sure all cables and connections are tight.
3. Remove the mirror plates according to (G.3). Check to ensure the mirror is remote and the motors are present.
4. Check that the motor arms and linking components are in good visual condition and function.
5. Use a tester unity to check the mirror function from the end of the control cable ate the door. If the mirror
functions properly, the fault is cab-internal.
6. Use a tester unit to check the function of the mirror head. If the mirror functions at this point, but not from the
control cable, the problem is in the control cable. Check the connections, and if necessary replace the control
cable according to __.
7. If the motor does not function when power is directly applied, the motor must be replaced.

(T.3) Removing, Attaching, or Adjusting the Mirror Head (From the Bracket)
Adjustment
1. Remove antenna. Use a 9/16” wrench to hold the antenna hex nut in place.
2. Remove back cover from the bottom first. See G.4
3. Slightly loosen all four clamps using a T30 bit or 3/16” Allen wrench. To prevent the mirror from sliding down,
hold in place from the bottom.
4. Adjust mirror head to the desired position. Tighten clamp screws to ~4 N-m.
5. Attach back cover, from the top first, in order to fit over antenna holder. See G.4 for details.
6. Attach antenna.
IT IS IMPORTANT TO ENSURE THAT THE DRIVER HAS THE OPTIMUM VIEWING ANGLE OF MIRRORS AT ALL TIMES.
Removal
1. Remove the antenna cover and the antenna.
2. Remove the back cover according to G.4.
3. Remove all four clamps by unscrewing the 8 screws that
hold the clamps. It’s important to note that after doing this,
stripping in the housing will occur. Therefore, it is recommended
to use 8 new screws that come with the kit.
Installation
1. Position the new mirror housing in order to give the
driver an optimum viewing level.
2. Attach the four clamps with the new eight screws using
a T30 bit and tighten to ~4 N-m.
3. Attach back cover by snapping into grooves of new
housing. See G.4 for details.
4. Attach antenna.
