Inspect the idler shaft thoroughly for:
 bends
 rust or corrosion
 cracks or breaks in the welding joints. (Vanguard and Vanguard2 only)
If any of these conditions are noted, replace the idler shaft immediately.
Inspect all the idler shaft fittings for:
 seized or worn bearings
 loose set screws at the bearings
 loose inner or outer flanges
Replace any seized or worn bearings. Perform the servicing procedure, Removing the
Idler Shaft and Installing the Idler Shaft to do this.
For all loose but otherwise good idler shaft fittings, perform the servicing procedure, Idler
Shaft Alignment. (Vanguard and Vanguard2 models only)
Installing the Idler Shaft (Conquest, Response, Bigfoot & Conquest 6x6)
Idler shafts on Conquest, Response, Bigfoot & 6x6 Conquest models manufactured
from S/N CB16970, RB17033, BF11543 & V6016200000C12747 utilize 1 retaining
ring on each shaft. These are seated to a machined groove on each of the shafts
during assembly of the floating sprocket. The right hand side idler shaft has an
“inboard” retaining ring, while the left hand side has an “outboard” retaining ring.
Vehicles prior to the above serial numbers do not have these retaining rings installed
to the idler shafts. The newer style idler shaft is fully exchangeable with the earlier
ones, however, during reassembly of the floating sprocket to the idler shaft, it should
be noted that it is installed facing opposite to the way it was originally installed on
the older style shaft.
Earlier sprockets were installed with the set screw hole facing outwards (towards the
outer bearing). The newer style shaft requires the sprocket to be installed with the
set screw hole facing inwards (towards the inner bearing).
IMPORTANT
If reinstalling the original idler shaft and floating sprocket assembly, it would benefit at
this time to wash the idler shaft and floating sprocket in a varsol bath to eliminate any
accumulated grease or dirt & debris build up between the teeth of the double sprockets.
