t
he M9 ACE’s ejector hydraulic
cylinder rod looks like a handy step,
especially when you step down into and
around the bowl to check the vehicle’s
compensation pump or look for a leak in the
valve bank.
Problem is, your muddy boots can scratch the
cylinder rod’s surface. A scarred rod tears up the
cylinder’s seal when the ejector moves back and forth.
That causes a hydraulic leak.
Excess hydraulic oil on the cylinder rod is a sure sign the
seal is shot.
So save costly repairs and downtime by staying off the
cylinder rod when you need to get inside the earthmover’s bowl.
W
ho would imagine that the lack of a small strap clamp could stop a 27-ton
earthmover dead in its tracks?
But it has happened. And that’s why
you mechanics need to remember the
clamp when servicing the Fve hydraulic
lines mounted directly across from the
engine’s exhaust manifold.
The clamp is needed to keep the
hydraulic lines from touching the ACE’s
hydraulic manifold. If a line touches the
manifold when it gets hot, the line could
melt and start a Fre!
The clamp gets misplaced when a
hydraulic line is replaced or the engine
is pulled. If the clamp’s missing, replace
it with NSN 5340-01-179-7530. You’ll
Fnd it listed as Item 40 in ±ig 156 of TM
5-2350-262-24P (Jun 12).
Until the new clamp comes in, secure
the lines away from the manifold with a
tie-down strap, NSN 5975-00-570-9598.
