Mechanics, here’s how to make the adjustment:
1.±
Remove the guard and
the brake screw cover.
2.±
Use a torque wrench and
turn the adjusting screw
clockwise until you get a
reading of 14-16 lb-ft.

Back off the screw

right clearance between
the brake linings and the

n order to start scoop loader bucket operations, you’ll need to unhook the excavator’s
spare tire carrier from the front bucket.
The carrier holds the spare tire, COEI hand tools and some BII items. All in all,
we’re talking about $10K worth of equipment here.
So make sure these items are out of the way during operations. You don’t want to
accidentally run over or drop a load on them.Also, don’t leave ’em behind at the work
site when it’s time to head back
to the motor pool. Hey, don’t
laugh! It’s happened on more
than one occasion.
That’s why it’s a good idea
to paint identifying marks—
like
your
machine’s
name
and bumper number—on the
carrier’s frame. That way, if
you
do
forget it, others at the
work site will know who to
return it to.
