**All mounting information assumes a “central” position of the BA bushing,
allowing an adjustment from plus “X” to minus “X”.
BA = Ecctrentric bushing. Eccentric mounting hole. By rotating the bushing on its mounting bolt, the clearance between the wheel and track can be adjusted.
BC = Concentric bushing. Concentric mounting hole. The major load should be carried on the stationary bushing.
