Gerry, The only spacer type thing I have seen for the army type TRB assembly is one that goes in between the bearing cones for the low range gear to limit the preload on this gear due to it's small size. Is this the one you are referring to? Apparently there were some failures of the bearings on this gear due to excessive preload. When they come loose the other 2 gears will also be loose and the bearing cones will rotate on the shaft. I have found that if the races are seated fully into the gears and the correct preload obtained (with a shim on the inner end under the plug that fits into the hole in the front of the t/c) the cones will not rotate on the shaft. Tapping the gears and shaft/bolt with a brass hammer when you torque it up will also help ensure the races are fully seated. When you torque the bolt up you will find the low range gear will have the most resistance to turning, the shim was made (by MD I believe) to fit exactly in between the cones and alleviate this. Good idea to check the bolt torque once a year. Only ever seen a few fitted although I do have one in mine.
