Your Paladin's hard-working
idler arm and housing don't always get the respect--or lube--they deserve.
I've had to adjust the tension on the
idler arm a couple of times, as the belt began to slip, making the plucker run too slowly to do good work.
The parallel-link steering subsystem is essentially a four-bar mechanism consisting of a pitman arm, center link, and
idler arm. A worm steering gear transmits motion from the steering wheel to the pitman arm.
If you don't lube the support arms, the bearings dry out and the
idler arm freezes.
I'M NOT AFRAID OF ANYONE WHOSE HAIR IS STIFFER THAN A PALADIN'S NEGLECTED
IDLER ARM!
And the ones on your Paladin's
idler arm and housing are a good example.
Use NSN 3110-00-100-5328 (PN 28584-28521, CAGE 60038) to get a new
idler arm roller bearing for your M113A3 FOV.
