et rid of the blind spot on the right side of your HEMTT by adding a spotter
mirror to the cab.
This spotter mirror, NSN 2540-00-401-8337, lets drivers see the area below
the front bumper to the second set of wheels. On the road, it lets drivers keep
track of cars passing and being passed.
To install the mirror, you’ll need a 21-in section of 1-in angle iron. Cut and
weld the angle iron at a 45
°
angle so you have a 10-in leg and an 11-in leg.
The 11-in leg is mounted to the cab
using the first two bolts of the right
front bumper. Drill
3

-in holes in the
leg to match the bolt holes.
Before you mount the leg to the cab,
drill a
1

-in hole one inch from the
end of the 10-in leg. That’s where the
mirror mounts.

WHAT'S THE
MATTER
WITH
YOU
?
YOU’d
better check MY
air cleaner
for
mounting stud
damage
.
ir cleaner assemblies for M1070 HET and M1074 and M1075 PLS tractors
are not cheap, so it’s tough to replace one just because a mounting stud is
damaged or missing.
But, if the assembly doesn’t seal
correctly, the truck engine can be
damaged, and that can be even more
expensive.
So, keep the seal between the air
cleaner mount and the element con-
tainer tight by using stud replace-
ment kit, NSN 5307-01-456-6938.
The kit contains one stud, one re-
tainer and one washer. Order as
many kits as you have damaged or missing studs.
