6-14 Repairing the Instrument
6WHS Position the Extension on the dual link bar with the measurement connector hard-
ware facing upwards and the arm of the dual link bar towards you. There are four
long mounting pins threaded into the Extension in each of the four corners under the
cover. Locate the heads of the two long mounting pins on the side away from you.
6WHS Use tweezers to prise the pins gently out enough to be removed by hand.
6WHS Remove the two pins and set them aside for refitting.
127(Do not lose these long mounting pins since the Extension will not function
unless they are in place.
6WHS Using your hands, gently pry the bottom cover away from the Extension at the link
bar end first. The bottom cover is press-latched at the link bar end. Remove it gen-
tly making sure not to bang or touch the inside of the Extension.
127( If you accidentally try to remove the wrong side of the bottom cover, you
will notice that it is attached to the inside of the Extension with a ribbon connector
and that the dual link bar prevents you from removing it completely. 'RQRWWU\WR
