Abstract
There is disclosed a method for compensating for wheel wear to maintain a constant car floor height above the railroad track where the compensating shim is at all times attached to the railway truck. The method comprises generally the steps of providing a wheel wear compensating shim that, when not being used, is removably attached to the underside of the bearing housing or other suitable location, lifting of the side frame away from the primary suspension, disposing the compensating shim between the side frame and the primary suspension, and finally lowering the side frame back onto the shim and primary suspension. The railway truck can thus be shimmed for wheel wear at any location where the side frame and accompanying car body can be lifted without the need to take the railcar to a retrofit service shop.
