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. One
idler shaft has an “inboard” retaining ring and the other an “outboard” retaining
ring. A better explanation of these retaining rings is discussed in the servicing
procedure, Removing the Idler Shaft, for those vehicles manufactured in the above
serial number range. This retaining ring minimizes the amount the floating sprocket
can float.
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 newer 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. The newer style shaft requires the sprocket to be installed with
the set screw hole facing inwards.
