 On 6x6 vehicles manufactured prior to S8131, locate and loosen off the four 1/2"-
20x1.5" power pack frame mounting bolts. Refer to Section 4.0 Power Pack As-
sembly Illustration in the appropriate parts manual. There is one located on each
side of the power pack frame in front of the idler axles, and one visibly located on
each side of the power pack frame, behind the idler axles. These bolts are threaded
into nuts welded to the lower frame assembly.
 On ARGOS manufactured from SN7841, S8131 and all RB, CB, BF & C vehicles,
locate the two 3/8"-16x3" bolts threaded into the lower frame channel beneath the
rear power pack mounting bolt. Turn each of these clockwise to lower the rear of the
power pack frame assembly. Photo WA-47
 On 6x6 models produced from S7304
and prior to S8131, undo the jam nuts
at the chain tensioner bolts and using an allen head wrench, turn the adjustment
bolts counter-clockwise to lower the back end of the power pack frame. This will
slacken the idler chains and allow for easy removal.
 On ARGOS manufactured from SN7841, S8131 and all RB, CB, BF & C
vehicles, Loosen the locknut in front
and behind the idler axles. These are
threaded to 2 mounting bolts inserted
through the power pack frame from
right to left and attached at the lower
frame. Photo WA-46
 6x6 Models prior to S7304, require a 3/4" socket on the adjustment bolt
head to lower the power pack frame.
