RE: Another T-55 build/review
The roadwheels are two halves glued together with a brass bushing between for the axle. This is basically the same assembly technique as other kit roadwheels. If bearings were desired, some additional modification would be needed.
The roadwheel assembly is held together by an e-ring clip, which did not clear the roadwheel mold to engage the axle key. All the roadwheels had to be shaved with a dremel to clear the access to the axle key in order to insert the e-ring.
To help with alignment, as the single brass bearing is a bit lacking in wobble support, a shim washer was added inner to the e-clip retainer on the axle. This is a step where ceramic grease that you supply can be applied before sealing the roadwheels.
Once the roadwheels were constructed, the axles insert into the suspension arms and secure by a set screw on a flat on the axle shaft. Fortunately, the flat has a tab on the end to prevent slipping out of the suspension arm should the set screw loosen.
The lower hull assembly is shown including the underbody which has some interesting detail as well.
