T
he winch frame locking tabs on the bridge adapter pallet (BAP) have been known to break
off during common bridge transporter operations.
Problem is, welding
a busted tab back into
place is a bit tricky.
There’s just not a lot
of elbow room in that
confined space. But the
locking tabs are critical
items

and

from

bridge transporter.
There’s a new 21-step field maintenance repair procedure that should be used to fix a
broken tab instead of WP 0054 in TM 5-330-263-13&P. To get an electronic copy of the fix,

lean air flters are important For all vehicles. And the HYEX is no exception!
A vehicle’s engine will run rough or not
at all iF its flters are clogged. A dirty flter
steals power and Forces the excavator to
struggle with any load in the backhoe.
Operators, it’s a good idea to squeeze the
dirt out oF the dust cap on the bottom oF the
air canister every day. That’s especially true
iF you’re in a dusty or sandy area. That gets
rid oF the dirt From the canister, but not From
the primary or secondary air flters.
Tap the primary flter with the heel oF your
hand to loosen dirt. Then give it a shake and
tap some more. That’ll knock some oF the
junk out oF the flter and allow you to keep
operating until you can replace the flter or
clean it with low-pressure air (30 psi).
Never bang the flter on a rock or hard
surFace. You’ll just dent it and ruin the seal.
Keep a close eye on the air cleaner indicator on the operator’s station inside the
cab. When the indicator’s light turns red, stop and clean the primary flter.
It’s a good idea to read up on how the canister and air flters ft together. That
means you’ll want to take a look at Pages 2-6, 11-5, 14-9 and 14-10 oF TM 5-3805-
280-10 (±eb 00).
