Work on changing the wheel sets are performed on a mechanized point or designated repair station routes, which for this purpose should have a supply of serviceable wheel pairs different in type and diameter of the wheel, lifting equipment and the necessary adaptations. The procedure works by changing wheel pairs depends on the design and type of trucks, cars, availability of lifting and other repair facilities.

For four-wagons to trucks with cast side frames and wheel sets with plain bearings this order is as follows:

If necessary, the rollout of the second wheel set one mechanic disconnects horizontal tightening connecting vertical and bypass levers, and the other using special clamps hangs the outer end of a four-beam connecting the trolley to focusing manhole covers at the intermediate beam frame gondola.
