 On ARGOS manufactured from SN7841, S8131 and all RB, CB, BF & C vehicles:
ii. Adjust the chains until the amount of deflection in both idler chains is less than 1/8"
(3mm) See Photo WA-49 on page WA-22
iii. Tighten all power pack mounting bolts.
iv. Perform the servicing procedure, Installing the Firewall.
Idler Chain Adjustment
i. Locate the two 3/8"-16x3" bolts threaded into the lower frame channel beneath the
rear power pack mounting bolt. Turn each of these counter-clockwise to raise the
rear of the power pack frame assembly and tension the idler chains. See Photo
WA-47 on page WA-21
10. Tension the idler chains
IMPORTANT
When adjusting idler chain tension, be sure to always alternate between each
adjustment bolt, turning each a little at a time.
iii. Tighten all power pack mounting bolts.
iv. Perform the servicing procedure, Installing the Firewall.
ii. Secure the jam nuts of each tensioner bolt.
i. Adjust the chains until the amount of deflection in both idler chains is less than 1/8"
(3mm) See Photo WA-49 on page WA-22
 On 6x6 models produced from S7304 and prior to S8131, use an allen head
wrench to turn the adjustment bolts clockwise. This will raise the back end of the
power pack frame and begin to tension the idler chains.
 6x6 Models prior to S7304 will require a 3/4" socket on the adjustment bolt head to
raise the power pack frame.
DO NOT over-tighten the idler chains. Chain deflection should be as described on
page WA-22. However, a loose idler chain can result in worn chain links, worn or
broken teeth on the idler or brake disc sprockets, a reduction in vehicle performance
and personal hazard to the operator. Please inspect the idler chain regularly.
