With vehicles racking up more and
more hours of use, the question comes
down to this: How much rubber is
enough?
According to the PMCS check on Page
A-4 of TM 5-2430-200-10, the mid-
rollers need 50 percent of their rubber to
work smoothly. The front and rear idler
wheels are NMC if they’re missing more
than 25 percent of their rubber.
That’s it–plain and simple.
Cab Air System
The flter element For the cab’s air
system is located next to your right elbow
when you’re sitting in the driver’s seat.
Most oF the time, the air system keeps
clean air circulating inside the cab, no
matter how dusty the worksite is.
But a loss oF Fresh air inside the cab
signals you to remove the flter element
to see iF it’s clogged with dust and sand. IF
it is, clean it with low-pressure air.
The brakes are hydraulically powered, so the brake system acts up when the
hydraulic fluid is low.
A clogged front or rear brake cooling Flter will also cause problems.
A clogged Flter starves the vehicle’s brake system for hydraulic oil. Low or no oil
means the brake calipers won’t open or close smoothly against the brake disc.
