This article contains substantiation of the improvement of inspection instruments used for the repairs of farming machinery during incoming quality inspection, in-process inspection, and acceptance testing. The design of a gauge plug has been developed for repairs and with the purpose of inspection of bushing bores of the intermediary shaft bearing with the diameter of Ø48.8 F 7 for ZMZ engines. The manufacturing tolerance for go-side and no-go side has been determined. The deviation of the middle of the tolerance range in relation to the smallest limiting size of the gauge plug was 3.5 μm. The permissible overrun of a worn-out of the gogauge outside of the tolerance range border was – 3 μm. The manufacturing tolerance for the size of the check caliper gauge has also been determined and limiting dimensions of the check gauge have been calculated. Taking into account the values derived a layout for the gauge plug tolerance range has been developed in order to inspect the bushing bores of the intermediary shaft bearing with the diameter of Ø48,8 +0,050 +0,0025 .
