It sounds like what you are seeing may be one side of the chain (top or bottom) being tight while the other is loose? If so, that is just the normal operation of the chain. As one sprocket starts to turn, it pulls the chain tight on either the top or the bottom, depending on which axle you are looking at and which way it is turning. As the chain gets tight, it turns the sprocket that the chain is connected to. That side of the chain that is pulling will be tight and the other side will be looser. Is that what you were seeing?
Tighten them up, just a tad of free play each side of chain and each side of trans. There are 3 cross bolts, though most loosen 2 rears if front is loose enough, use small upright bolts to adjust evenly and then tighten cross bolts.

From Argo owners manual..
7.2.5 IDLER CHAIN
All ARGO vehicles are equipped with 2 idler chains to transfer
power from the output shafts of the transmission to the
drive chains through a series of sprockets. They are located
on each side of the transmission.
A loose or improperly adjusted idler chain can result in damage
to the chain or sprockets. During the new vehicle breakin
period, check the idler chain adjustment before operating
the vehicle and after the first 2 hours of operation. After the
initial break-in period, check the idler chain adjustment every
50 hours. An indication of loose idler chains is a loud banging
noise when the vehicle is turned.
To check the idler chain adjustment, push the slack side of
the chain and measure the amount of chain deflection (Figure
7-15). Adjust the idler chain tension if deflection is more
than 3mm (1/8").
Idler Chain Adjustment
1. Remove the firewall from the vehicle as detailed in Section
7.3.1 for the Vanguard and Section 7.4.4 for the Vanguard2,
Bigfoot, Response and Conquest.
2. Loosen the 2 left side clamping nuts and 1 front pivot
shaft nut with a 15/16" sprocket wrench (figure 7-16).
Loosen the 3/8" hex nut (117-15) securing the adjustment
support (602-27), just above the transmission, to
the hood frame assembly. (Refer to Section 6.0 of the
Parts Manual.)
3. Turn the vertical adjustment bolts counter-clockwise to
raise the power pack and tighten the idler chains. The
idler chains are properly adjusted when the deflection
measures 3 mm (1/8"), (Figure 7-15).
4. Tighten the 2 left side clamping nuts and 1 pivot shaft
nut securely. Tighten the adjustable support fasteners with
the rubber bumper (126-88) pressed down firmly onto the
top of the transmission.
I have the argo owners manual in pdf format. I can email it to you if you like. Admin Mike I can email it to you too so we can have it on the website under manuals.

I've read in the manual not to over tighten the idlers as that will also cause damage. Hope I've explained the question well enough. I'm working on my new to me 2001 bigfoot. Thanks for any guidance.
I have thought the same thing...seems like a very arbitrary adjustment. You could mess with the adjustment for hours if you get too picky. Tighten them, check for some deflection, button it up.Quote:

Thanks again for your input.Quote:
